Plastic injection moulding is a widely used manufacturing process for creating everything from car parts to toys. But in today’s environmentally conscious world, an important question arises, “Is plastic injection molding environmentally friendly?” 

By implementing certain sustainable practices, the plastic injection moulding process can be made more sustainable and energy efficient, resulting in less waste, a reduction in overall costs and less negative environmental impact.

What are Sustainable Practices in Plastic Injection Moulding?

Numerous areas in plastic injection moulding can be optimised to make the process friendlier to the environment. These include:

  • Utilising recycled plastic materials
  • Reducing energy consumption
  • Selecting sustainable plastic materials
  • Effective waste management

is injectionmoudling sustainable for plastic manufacturing

Utilising Recycled Polymers

When considering sustainable practices, you may wonder, “Can recycled plastic be injection moulded?” Recycled plastics can be successfully injection moulded and this practice is becoming increasingly common as more industries focus on sustainability. Processes like closed-loop recycling allow plastics to be recycled within their polymer types to create the same product or different high-quality products of the same type of plastic. Utilising recycled plastic material not only reduces the demand for virgin plastics but also lowers fossil fuel consumption and cuts down the amount of plastic waste in landfills.

 

Reducing Energy Consumption in Plastic Injection Moulding

The plastic injection moulding machines and the additional equipment involved in the plastic manufacturing process require a lot of energy to operate. Traditional plastic injection moulding machines wasted a lot of energy and were powered by hydraulics and fossil fuels until the late 20th century. 

Today, modern electric plastic injection moulding machines are much more energy efficient. As well as utilising renewable energy sources to increase sustainability further, modern plastic injection moulding machines allow for tighter control of process parameters which makes production and energy use much more efficient. 

Plastic injection moulding involves heating polymers to high temperatures and using high pressure to inject the melted polymers into their moulds. Since temperatures and pressure levels for various types of plastic will vary, expert injection moulders can optimise these parameters by reducing cycle times to maximise production and reduce unnecessary energy consumption. 

 

What are the Sustainable Plastics For Injection Molding?

Due to the significant environmental impact of producing, using and disposing of conventional plastic, finding eco-friendly alternatives to traditional polymers has become a top priority for plastic manufacturers. 

In response, the plastics industry has been developing environmentally friendly materials such as:

  • Bioplastics – These bio-based versions of traditional plastics, such as bio-polyethylene are made from sustainable, renewable raw materials like sugarcane, vegetable oils, or food waste.
  • Biodegradable Plastics – Polymers like Polylactic Acid (PLA) and Polyhydroxyalkanoates (PHA) are not only bio-based but are also capable of being broken down by naturally occurring microorganisms.
  • Compostable Plastics – These plastics decompose into natural substances like water and biomass.

Other thermoplastics like Polycarbonate (PC) and Acrylonitrile Butadiene Styrene (ABS) are also recyclable making them excellent sustainable plastics for injection moulding.

Utilising these sustainable plastics in the plastic injection moulding process helps lower the carbon footprint and reduce plastic waste. 

 

Minimising Waste in Plastic Injection Moulding

Waste in plastic injection moulding typically includes excess material known as sprues and many facilities like Fern Plastics choose to recycle and reuse this plastic material in production. By using in-house granulators to repurpose the waste material, we are also able to reduce the amount of time and resources needed to transport the waste to another facility for processing. 

Waste reduction, however, goes beyond the materials used in the injection moulding process. It also includes reducing wasted time and costs. Processes like lean manufacturing aim to reduce lead times and operating costs while maximising productivity and improving the quality of the end product.

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.

7 ways to improve the plastic manufacturing process

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.

Injection Moulding Costs – Is it Cost-Effective?

The plastic injection moulding process produces hundreds and thousands of products every single day. From large-scale production projects to smaller, more bespoke mouldings, plastic injection moulding can produce a wide variety of shapes, styles and finishes, all with perfect uniformity. Low injection moulding costs mean that extremely large quantities can be produced with little effort in a relatively short space of time. Here’s our guide to the cost-effectiveness of plastic injection moulding.

Is Plastic Injection Moulding Cost-Effective?

One of the most attractive elements of plastic injection moulding is that is it an extremely cost-effective plastic product production process. Huge amounts of product can be produced from just a single injection mould making it a time-efficient and cost-effective production process. Whilst the initial costs may seem higher than other plastic production methods, he ability to produce tens of thousands of parts from one tool means that plastic injection mould costs, in the long run, are extremely cost-effective, especially for larger-scale or repeat projects.

Creating the Right Mould for your Project

Whatever your project, the right plastic injection mould can help make it a success without the gruelling production process other types of product creation may involve. At Fern Plastic, we know what goes into creating the perfect mould for the plastic injection moulding process and know that the right mould can save time and resources on post-production adaptations later on down the line.

How Do We Save Money on Injection Moulding Costs?

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.
