Mailbox - Injection Moulding
Simple, reliable and efficient
High pressure injection moulding is an extremely versatile and popular method of producing plastic parts and components, especially those requiring detailed features and complex geometry.
Key injection moulding benefits
- Accuracy – injection moulding is very precise, so can fabricate nearly any type of plastic part
- Volume – production can be scaled to allow extremely large runs
- Speed – injection moulding is ideal for long production runs as it is very fast (depending on the complexity of the mould being used)
- Less waste – the process only uses as much plastic as is necessary to create the part so it has a low scrap rate. Any excess it can be ground up and recycled after use
- Flexible – it’s easy to change the type of material and colour being used
- Strong – fillers can be added during processing to add strength to the final product
- Smooth – finished items need little or no end finishing
- Consistent -injection machines deliver consistent output and quality.
The team at Mailbox is experienced in delivering injection mouldings of the highest standard, working out of a UK facility equipped with the latest machinery.
Customers choosing Mailbox benefit from:
- Delivery in company vans from small to HGV
- Fully automated production facilities
- On-site warehousing
- Capacity to run 24/7 if required
- Design to inception of parts
- Gas injection and foam moulding capabilities
- Material is introduced into the injection moulding machine through a hopper.
- A heated barrel equipped with a reciprocating screw (driven by a hydraulic or electric motor) feeds the molten polymer into a temperature controlled split mould via a channel system of gates and runners.
- The screw melts or “plasticises” the polymer and acts as a ram during the injection phase. The screw action also provides additional heating because of the shearing action on the polymer.
- The polymer is injected into a mould tool that defines the shape of the moulded part.
View Rotational moulding
Rotational moulding machines come in a wide range of sizes and normally have moulds, an oven, a cooling chamber, and mould spindles. The spindles are mounted on a rotating axis to provide a uniform coating of the molten plastic.
