7 Ways to Improve the Plastic Manufacturing Process

As the demand for plastic products continues to rise, plastic manufacturers face increasing pressure to enhance their operational efficiency to stay competitive. Efficient operations play a crucial role in reducing costs, improving product quality, and meeting the ever-growing consumer demand. If you’re exploring plastic manufacturing services, understanding the latest techniques is crucial for achieving superior product quality. As an expert injection moulding company, here are a few of the techniques we implement to enhance our plastic manufacturing processes.

 

Optimise Injection Moulding Processes

Injection moulding is often at the heart of plastic manufacturing and when it comes to optimising plastic manufacturing processes, it’s best to take a systematic approach. 

The first step is the initial functionality testing and examinations. The mechanical functionality of moulding tools is thoroughly evaluated to ensure alignment with thermoplastic settings. Additionally, procedures like short shot testing focus on assessing issues like dynamic pressure loss and cavity imbalances in multiple-cavity tools.

Engineers then observe pressure curves and sample weight to determine the effectiveness of gate seals and identify sealing points during the moulding process. 

Next, sample parts are evaluated and defects are examined and recorded. Any recommendations for necessary adjustments to the process and the tool are documented while information about melt temperatures, fill time, tool temperature, coolant flow, cycle time, and pressure curves, is recorded.

At this stage of the process, the sample parts undergo rigorous quality control examinations which include assessing measurements and overall quality documentation. Any necessary tool adjustments are made based on the findings from the quality control phase and new sample parts are made if needed. The newly adjusted sample parts undergo the same quality testing procedures, with further adjustments made as needed.

To ensure the best results, the testing and adjustment process is continued until all process parameters meet the designated performance ranges.

 

Utilise Gas Assist Injection Molding

The type of plastic manufacturing process applied can also help create a superior plastic product. Gas assist injection molding takes precision to the next level by introducing nitrogen gas into the mold cavity. This innovative technique not only strengthens complex parts but also eliminates cosmetic defects like sink marks and surface irregularities. The lightweight yet robust components produced through gas-assist injection molding offer a winning combination of structural integrity and impeccable surface finishes, meeting the highest standards for your end product.

 

Enhance the Thermoplastic Material Selection

Selecting appropriate molding material is a crucial factor in enhancing the overall plastic manufacturing process. Proper material selection goes beyond meeting the basic structural requirements of a design. Choosing the right high-performance polymers is a strategic decision that influences the efficiency, cost-effectiveness, and quality of the entire production cycle. 

By carefully considering factors such as material flow characteristics, shrinkage rates, heat resistance, and chemical resilience, plastic manufacturers can tailor their selection to match the unique demands of each project. This precision in the thermoplastic material selection ensures the seamless functionality of the plastic manufacturing process. Additionally, careful material selection contributes to the production of high-quality, durable, and precisely engineered plastic parts.

Plastic Injection Moulding Vs Vacuum Moulding

 

When it comes to plastic moulded products, two main moulding methods are often discussed, plastic injection moulding and vacuum moulding. But what is the difference between plastic injection moulding and vacuum moulding? We go into the differences between the two plastic moulding types and more.

plastic injection molding vs vacuum moulding

What is Plastic Injection Moulding?

Plastic injection moulding is the process of injecting molten plastic into a pre-designed mould in order to create a plastic moulded product. By injecting molten plastic into a mould at high pressure, the plastic is forced to fill the gaps in the mould and create the shape of the mould design. Once the plastic has cooled, the mould is opened and the plastic injected products are removed from the moulding machine. 

What Type of Products Are Made From Plastic Injection Moulding?

Plastic injected products can be found everywhere in the home and beyond. Plastic injection moulding is often used to produce items such as recycling bins, medical tools, car parts, toys and more with the ability to highly customise the plastic mould meaning that a wide range of intricate designs can be produced in numerous quantities.

What is Vacuum Moulding?

Vacuum moulding, also known as thermoforming, is a process during which a heated sheet of plastic is stretched over a vacuum forming tool in order to form a plastic part. The thermoforming plastic sheet forms the shape of the mould through a vacuum process and as the sheet cools it forms a hard shape before the moulding tool is removed.

Here’s how the thermoforming process works:

  • Preparation – A flat sheet of thermoforming plastic is clamped into a frame. The type of plastic chosen depends on the specific requirements of the part being produced.
  • Heating – The sheet is then heated until it becomes soft and pliable. The temperature and heating time vary depending on the material’s thickness and type.
  • Moulding – After the thermoplastic sheet is heated to the desired temperature, it is quickly moved to the mould or tool.
  • Thermoforming – Once the heated sheet is in position over the vacuum-forming tool, a vacuum is applied beneath the mould, which suctions the plastic sheet tightly against the mould’s surface. This forms the plastic into the shape of the mould. Any excess material is trimmed away.
  • Cooling and Release – After the plastic has taken the shape of the mould, it is cooled. Once it has cooled and solidified, the vacuum is released and the formed plastic part can be removed from the mould.

What Type of Products Are Made From Vacuum Moulding?

Depending on the design of the plastic moulding, vacuum moulding can create a variety of designs and styles. Items such as plastic bathtubs, garden equipment and plastic utensils can be made using the vacuum moulding process.

Plastic Injection Moulding Vs Vacuum Moulding, Which is Best?

When it comes to plastic formed products, each technique is different. For tight tolerances, plastic injection moulding is often more suitable than vacuum forming whilst the plastic injection process can also often work out as cheaper than the vacuum moulding process, particularly for larger projects where a high volume of plastic injected products need to be formed. The process of vacuum forming is sometimes also less controlled than plastic injection moulding die to the heated plastic being stretched over a mould.

What are the Advantages of Injection Moulding Compared to Vacuum Moulding?

There are a few advantages to using plastic injection moulding when compared to vacuum moulding.

High precision and tight tolerances – Plastic injection moulding allows for the production of parts with extremely tight tolerances and high precision. This process is capable of producing complex, intricate parts with consistent wall thickness, intricate details and minimal variations. In contrast, vacuum forming may have some limitations in achieving the same level of precision due to the stretching of the heated plastic sheet over the mould.

Higher production volumes –  Injection moulding is better suited to high-volume production runs when compared to vacuum moulding. The cycle times in injection moulding are typically faster than vacuum forming, and the process can produce a large number of parts in a shorter period of time. This efficiency makes it more cost-effective for long production runs

Material selection – Plastic injection moulding allows for the use of a range of thermoplastic materials including high-performance engineering plastics like Acrylonitrile Butadiene Styrene (ABS), Nylon (PA) and Polycarbonate (PC). This means that injection-moulded parts can have superior properties such as heat resistance, greater strength, chemical resistance and more. Injection moulding is often chosen when the application demands specific material characteristics and performance.

Everything You Need to Know About Plastic Injection Moulding

Plastic injection moulding is present in almost every area of our modern-day lives. From toy shops to your bathroom, you’ll find items created from the plastic injection moulding process. But what exactly is plastic injection moulding? In this guide, we explain what injection moulding is, how the process works, its advantages and how we create the best products that are using this high-quality process.

plastic injection moulding uses

What is Injection Moulding?

Plastic injection moulding is the process of creating plastic products from a mould. This is done through melting plastic pellets otherwise known as thermoplastic polymers until they are malleable enough to be injected into a mould cavity at pressure to form, when cooled, a solidified final plastic product. 

This process is known for its precision and ability to create complex and detailed parts with unrivalled consistency. Plastic injection moulding is widely utilised across industries such as automotive, electronics, medical device production, consumer manufacturing and more due to its cost-effectiveness, design flexibility and fast production capabilities. Plastic injection moulding techniques allow the mass production of plastic components while maintaining accuracy and high quality. This makes it an important technique in modern manufacturing.

The Injection Moulding Process

Understanding the details of the injection moulding process is key to appreciating its versatility and why it is a preferred manufacturing technique in many industries. Here are the steps in more depth.

Thermoplastic Material Selection 

The process begins with the careful selection of plastic material. Various types of thermoplastic resins can be used, each offering specific properties suitable for different applications. Factors like durability, flexibility and heat resistance are considered when choosing the right material.

Melting and Injection

Once the thermoplastic material is selected, the prepared product mould is clamped firmly to prepare for injection. Molten thermoplastic material is injected into the mould under high pressure. This is usually done using a ramming device or a screw-like plunger. More pressure is then exerted on the mould to ensure that all of the mould’s cavities are filled with molten plastic. This is done through either mechanical or hydraulic pressure and ensures a smooth, complete product.

Injection Moulding Cooling and Solidification

After injection, the molten plastic is then left to cool and solidify within the mould. The cooling process is carefully controlled to ensure consistency and prevent defects in the final product.

Ejecting the Mould

Once the plastic has solidified, the movable metal plates used to hold the mould are separated from the fixed point in order to separate the mould. Rods, a plate or an air blast are used to eject the newly formed plastic part from the mould. This step is critical to maintain production efficiency and minimise cycle times. At this stage, Fern Plastics then aims to recycle and reuse any plastic waste from this process to create a circular plastic injection moulding process.

Here at Fern Plastics, we have a number of years of experience creating high-quality plastic injection moulds and injection moulded parts. We like to think that our process has been streamlined to be as cost-effective and environmentally friendly as possible in order to pass on those benefits to our customers. Some of the ways to keep plastic injection moulding costs as low as possible whilst still maintaining ultra-high quality levels include things such as modifying and reusing moulds to improve their performance and continue creating brilliantly-bespoke plastic injection moulded products. We also aim to recycle and reuse the majority of our product waste in order to lessen the environmental impact of the injection moulding process.

Here’s an in-depth look at how injection moulding costs can be reduced.

Optimise The Design of Moulded Parts

Smart part design is one of the most impactful ways to reduce the cost of plastic injection molding. By working closely with experienced engineers, you can create parts that are easier to mould and reproduce. Not only does this demonstrate design best practices, but also improves product efficiency. This results in reduced material requirements and minimises the need for secondary processes. Consider design elements like uniform wall thickness and avoiding undercuts or other intricate features that may require complex tooling. With efficient part design, overall cycle times are reduced with fewer discarded parts which saves time and money.

Select The Right Injection Moulding Material

Choosing the right injection moulding material is vital for cost reduction. While high-performance resins may offer excellent properties, they can significantly increase production costs. Injection moulding specialists will evaluate the required properties of the part carefully and consider using alternative materials that meet the necessary specifications at a lower cost. Recycled plastics can also be a viable option for certain applications, which reduces both material expenses and the impact on the environment. 

Optimise Tooling Design and Maintenance

Investing in high-quality tooling ensures consistent part quality and extends tool life. While initial tooling costs might be higher, better-quality moulds can result in lower production costs in the long run. Regular maintenance of the moulds is essential to prevent part defects, downtime and costly repairs.

Utilise Multi-cavity Molds

Using multi cavity molds allows multiple parts to be simultaneously produced in each molding cycle. This approach significantly increases the efficiency of production while reducing cycle time and lowering the overall cost per part. However, it is essential to balance the savings with the maintenance requirements of complex multi cavity molds.

Minimise Post-Molding Operations

Reducing the need for post-molding operations can save both time and money. Creating parts that require minimal or no secondary processes such as additional surface finishing and trimming. Integrating features directly into the mould can eliminate the need for additional manufacturing steps.

Mould Design Modifications

Before production, it is worth closely analysing the structural requirements of moulded parts. By closely examining the part’s structure, areas that are critical for function and quality can be identified and other areas can be modified. For example, gussets or ribs can be used to enhance the structural integrity of the part, replacing a completely solid area. This not only simplifies production but can also reduce weight, making it cost-efficient for shipping, storage and delivery. Additionally, replacing solid areas with hollow sections where appropriate, reduces the amount of injection moulding material used in the process which can further reduce costs. However, it is important to ensure that the quality isn’t compromised by the modifications as any savings would be cancelled out by the costs associated with failed parts.

Collaborate with Expert Injection Moulders

Partnering with experienced injection moulders can provide valuable insights and cost-saving suggestions. Collaborate with an injection moulding company that has a proven track record of optimising injection moulding processes and can offer innovative solutions and value-added services to cut costs without compromising quality.

How We Avoid Common Defects in Plastic Injection Moulding

When it comes to manufacturing quality plastic injection moulded products, we are experts in our field. From the smallest, intricate part to large, mass-produced plastic moulded projects, we have experience and skills to perfect your products. When it comes to plastic injection moulding, there will always be risks of defects in the finished product. Here are just some of the ways we avoid injection molding defects in our injection moulding process using high-tech machinery and skills to create your perfect product.

Avoiding Air Pockets and Vacuum Voids During the Plastic Injection Moulding Process

When creating bespoke products using plastic injection moulding, it is extremely important to avoid the creation of air pockets during the process. A bubble defect in injection molding can be the result of volatiles from the resin, the decomposition of gases from polymers or additives or moisture vapour. This can inadvertently distort the shape and use of the finished product. As experts in our field, we have a number of processes in place to avoid this in our plastics mould manufacturing process. We also have high-tech machinery to optimise the process and ensure adequate moulding pressure forces any excess air out of the moulding cavity. Our high-tech plastic injection moulding machinery also ensures premature cooling does not happen, another cause of air pockets in the moulding process.

Preventing Burn Marks in Our Plastic Injection Moulding Process

In some cases when creating plastic injection moulded products, burning can appear. In many cases, this can be due to air or even resin becoming trapped in an air cavity and overheating. This then results in the scorched material. Here at Fern Plastics, our skilled team members prevent burn marks in injection molding by loosely monitoring the temperature of our plastic injection mouldings and the speed of our injection mouldings to ensure this doesn’t happen to our products.

Avoiding Plastic Injection Mould Warping

As with any materials, when treating plastics and using them during the plastic injection moulding process, there is a risk of warping the materials. A warping defect in injection molding has a range of side effects including excessive space produced between components and misshaped products. Warping as an effect of the injection moulding process can be caused during the cooling process when uneven shrinkage can put stress on different parts of the plastic product. Often, the materials used can be prone to developing warping defects. Materials with semi-crystalline structures are more likely to be subject to warping. We combat this through strategic selection of materials and expert mould design to avoid this. We also ensure an even and gradual cooling process to avoid warping of the plastic injection moulded product.

Jetting During the Plastic Moulding Process

A jetting defect in injection molding can occur when the solidification process happens unevenly. In order to create a smooth, streamlined plastic injection moulding without any jetting, it is important to use the perfect injection pressure for your product to avoid initial streams solidifying before the product is finished. We have years of experience perfecting the plastic injection moulding process so make it our priority to provide an exceptional product and service each and every time. Our innovative machinery calculates the exact pressure needed for every moulding whilst our mould designs optimise for a smooth finish.

Preventing Sink Marks in Injection Molding

Sink marks are common defects in injection moulding often found in thick-walled sections. One of the main causes of sink mark defects relates to incorrect melt temperatures. We are able to prevent the formation of this defect by understanding the importance of staying within the temperature range recommended by the resin manufacturer. Since thick sections contain more plastic, failing to verify the temperature can result in the part taking longer to cool which will lead to the formation of sink marks. As well as verifying the correct temperature during the injection moulding process, we make sure the correct second-stage pressure and pack and hold times are maintained. The ideal second-stage pressure (or pack and hold pressure) not only helps to prevent shrinkage but when combined with the proper pack and hold times, ensures the part is efficiently sealed which can prevent sink marks from forming. Where applicable, we apply gas-assist injection moulding processes to help reduce the appearance of sink marks.

Avoiding Short Shots in Injection Molding

During the injection molding process, partially formed parts known as short shots occur when the resin hasn’t entirely filled the mold cavity. The result is a plastic part that is visibly incomplete and often unusable. We prevent short shots in injection molding by ensuring a consistent flow within the mold cavity which can be affected by blocked or narrowed gates. We also avoid short shots by adjusting the mold temperature and maintaining the correct injection pressure so that the entire mold cavity is filled during mould injection. 

Weld Lines in Injection Molding

A weld line defect is formed when two flows of injected resin material meet within the mould cavity. Also called a “knit line”, these marks usually form around holes as the plastic flows around either side. When the temperature of the resin is incorrect, the two flows fail to bond together properly which results in a visible weld line. Weld line defects reduce the durability, strength and aesthetic quality of the plastic component. To combat the formation of a weld line defect in injection molding, we can make adjustments to the mould design as well as raise the temperature of the molten resin which prevents it from solidifying too fast. Low-viscosity resins with lower melting points are often less prone to developing weld line defects. We also adjust the injection speed and pressure where necessary which also prevents early solidification and the formation of knit lines.

Can Injection Moulded Plastic be Recycled?

Countless objects around the world both inside and outside of the home are now made from plastic. However, plastic waste has become a huge problem for the planet with many non-recycled plastic products going to landfill. As producers of plastic injection moulded products, we answer questions such as can injection moulded plastic be recycled and what we are doing to help reduce plastic waste in the injection moulding industry.

Can Injection Moulded Plastic be Recycled?

When it comes to recycling your plastic moulded products, the good news is that most of the time, the plastic they are formed from can be recycled. At Fern Plastics, we ourselves recycle our plastic waste in a conscious effort to reduce the amount of plastic we dispose of. Plastic injection moulding uses molten plastic injected into pre-made moulds to form a finished plastic item. These injection moulded plastic products are used for everything from car parts to household items such as cutlery and toys, many of which will be recyclable. The plastic used in these injection mouldings and products made from recycled materials can be reused and reformed time and again to reduce waste.

Recycling plastic that has been injection moulded does not result in any loss of quality making it ideal for the rapid production of recycled plastic products on a large scale. As well as reducing waste going to landfill, recycling our plastic waste and reusing plastics within our process helps to reduce the amount of raw materials needed for plastic injection moulding, reducing pollution.

 

How Do You Reduce the Amount of Plastic Waste at Fern Plastics?

At Fern Plastics, we know how important it is to reduce the amount of plastic waste we produce. That’s why reuse and recycle up to 100% of our plastic and manufacturing waste to be used for future projects without compromising on quality. We also recycle the plastic bags our raw material is supplied in and use in-house robots and granulators to recycle plastic waste. Our state of the art machinery ensures that every piece of plastic we use for our injection mouldings is used to its full capacity whilst our partners Recycled UK then re-process any plastic we cannot use for other non-technical markets. Manufacturing with recycled materials and recycling our plastic waste helps us to reduce the amount lost in our plastic injection moulding processes.

Why is Plastic Injection Moulding So Effective?

Plastic injection moulding is one of the most efficient and cost-friendly plastic product production processes. Countless household and business products are formed from plastic injection moulding, perhaps even items you didn’t think were injection moulded. We talk through why plastic injection moulding is so effective.

What is the Plastic Injection Process?

Plastic injection moulding is conducted through precisely injecting molten plastic at pressure into a specially-designed mould. Once the molten plastic cools, a firm product is produced that can stand the test of time. Over moulding and other processes can be used to create more bespoke, intricate plastic injection moulded designs that work for a variety of purposes.

Why is Plastic Injection Moulding So Effective?

Fewer plastic production processes are as effective as plastic injection moulding. One of the main reasons for this is the impressive cost-effectiveness plastic injection moulding enjoys. Injection moulding can produce high volumes of identical products with ease and with a much quicker turnaround than other plastic moulding processes. The efficiency of the injection moulding process is also a factor in the fantastic cost-effectiveness of plastic injection moulding. Once the specialised injection mould has been designed and created by our in-house experts, that same mould can be used countless times, producing plastic injected products with ease at very little cost per item.
