Injection Moulding Trainer offers a classroom-based resource for investigating the techniques used to create thermo-plastic products. Students initially use the trainer to mould a variety of items, including a model car and different designs of door handles.

Using the trainer alongside a 3D printer allows students to follow rapid prototyping and tooling techniques, including:

• 3D printing, evaluation and improvement of prototypes
• 3D printing of injection moulds
• Injection moulding of the final product

Students apply these techniques to develop various items, including a headphone cord wrap and a multi-part gear mechanism.

Students will see how a good grasp of the science of material properties is needed to select appropriate materials and methods for production. They will also gain an understanding of how mathematics is required to develop production costs and propose selling costs.

This resource can also be used in conjunction with Optional Cloud-based Software, which offers online practical tasks as well as interactive theory presentations, investigations, and assessments, which link directly to the practical activities carried out using this resource.

Training Concepts:

• Injection mould the parts for a model car
• Mould different doorknob designs and test each one for strength
• Adapt an existing mould design to make a corn cob holder
• 3D print an injection mould tool
• Adapt a 3D printed mould tool to overcome moulding problems such as flashing, surface finish and shrinkage
• Explore the benefits of adding a draft angle to a mould
• Design project - design a new component suitable for mass production

Trainer includes:

• Injection Moulder and Lever
• Mould Set containing:
• Single-part mould (for moulding tokens)
• Multi-part mould (for moulding a model car)
• Adaptable ‘smart’ mould (for moulding door handles, screwdrivers and corn cob holders)
• Support jacket for 3D printed moulds
• Plastic Granule Supply (5 kg)
• Model Cabinet Door (for testing door handle designs)
• PPE (Gloves)
• Curriculum CD
