Mailbox - Injection Moulding
Simple, reliable and efficient

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.

Advanced Machinery

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

The process

• 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.
