PLASTIC INJECTION MOLD TOOLING is suited to high volume manufacturing, as it is capable of creating multiple quantities of solid plastic parts repeatedly with a very fast production cycle.
Each mould will have a unique design, that will be able to withstand high pressures involved, and provide a channel for the molten plastic to flow into the mould, extract heat from the part and provide a method of separating the part once it is has solidified.
What is Plastic Injection Mould Tooling?
Plastic Injection Mould Tooling is the creation of unique moulds that are used to manufacture plastic parts.
The plastic moulds consist of both moving and fixed sections which are clamped together at the beginning of the manufacturing process.
Molten plastic is then fed into the clamped mould at a very high pressure. If gas assist systems are used then air is pumped into the mould to ensure the plastic is uniformly covering the entire cavity.
Finally, the plastic is cooled and hardened within the mould, before the tool opens to release the component.
The injection moulding process has several benefits over other plastic moulding processes:
- Products can be produced in complex and intricate detail which, otherwise, would be too costly or difficult to make
- The production rate is high, labour costs are low ,with very limited production downtime
- The process makes complete products that can be used for whatever they are designed for
- Faulty products may be recycled for future use, therefore almost eliminating waste
- A wide range of materials can be used, from Polypropylene to high performance engineering polymers
Our moulds are constructed from hardened steel. These steel moulds are more expensive to construct but they have a longer lifespan because of steel’s strength and hard-wearing properties. This makes hardened steel moulds suitable for mass production volume which will offset the initial mould tooling costs.
Project management is key to the success of Plastic Injection Mould tool manufacture and we have developed procedures to ensure that each project runs smoothly, to specification and within schedule. The requirements of each customer are unique and to reflect this our tooling specifications are split into three classes – see table below.
As part of our standard process we check component cad data for mouldability.
Any issues are highlighted along with our recommendations.
We have the following Quality Management Process:
• Depending on the requirements of your project, our expert tooling team will design high quality plastic injection mould tools to suit your product design and production
• Once your product design has been finalised ready for manufacture, it is then time to
create your plastic injection mould tool.
• 3D tool designs including DFM reports are issued electronically and if the parts are complex Moldflow analysis will be completed.
• On design approval you will receive weekly schedules and photographs.
• One of our UK Engineers will attend tool trials to monitor mould quality and debug if
• Between 5 & 10 sets of parts are delivered for approval along with dimensional reports.
Any warranty issues are managed by Toolcast at one of our partner UK toolrooms.
