Discover more about all of our services below and find out how they can be applied to your injection moulding requirements to improve your end product.

Value Added Service During the Plastic Injection Moulding Process

Gas-Assisted Injection Moulding

One of our popular injection mould services is gas-assisted injection moulding. This injection moulding technique improves aesthetics and reduces material content in thick sections. This variant of traditional plastic injection moulding uses pressurised nitrogen gas to maximise the resin flow inside the mould cavity. Gas-assisted injection moulding is an environmentally friendly value-added service that is also cost-effective.

Ultrasonic Welding

Joining injection moulded parts by ultrasonic welding or heat welding is quick and efficient. The process of ultrasonic welding eliminates the need for screws, nails or bolts when joining complex parts. Pressure and ultrasonic frequencies are transmitted to the parts which are fused by vibration and heat. Ultrasonic welding is suitable for small complex parts and parts that need to maintain their aesthetic quality.

Plastic Insert Moulding

All injection moulds can be customised to include moulded-in fasteners, shafts, hubs, electrical contacts or connectors. The insert injection molding process involves moulding plastic around other non-plastic inserts. Insert moulding is used for simple projects as well as complex moulding. Insert injection molding is economical, efficient and offers a variety of options for design.

Assembly & Test

At Fern Plastics, plastic injection moulded parts are joined together using techniques like mechanical fastening, with springs or o-rings. An experienced team of engineers test moulded assemblies for pressure tightness to guarantee the quality of the end products.

Injection Mould Printing

Pad printing, also known as tampo printing or tampography is the process of printing 2-dimensional images onto 3-dimensional shapes. This process gives you the freedom to print on complex substrates with uneven surfaces and shapes and produces high-quality detailed images. A silicone pad is used to transfer the images and up to 5 colours can be printed in one process using state-of-the-art tampo-printers.

Laser Marking

Fern Plastics’ laser marking machine produces indelible marking or etching on plain, chromed or painted mouldings. We use precise layer removal to produce back-lit mouldings for medical uses or applications that require backlit electrical components. An efficient laser marking service offers detailed laser etching for serial numbers, barcodes and QR codes.
