Technical moulds for the plastic injection moulding industry

What is a standard plastic injection mould?

Injection moulding is a widely used manufacturing process in the plastics industry. It involves injecting molten plastic under high pressure into a closed mould to form solid parts once cooled. A standard mould is custom-designed to match the desired final shape of the part to be produced.

These moulds can be produced using direct injection or sprue injection, a configuration suited to the simultaneous production of multiple parts. We also offer hot runner moulds, which prevent the formation of what are known as sprues. These are plastic residues that form in traditional feed channels, thereby helping to reduce material waste.

A conventional mould produces plastic parts using a ‘sprue’, a channel that feeds molten material into the mould cavities. This is the most common injection moulding method as it is simple, reliable and cost-effective.

The hot runner mould keeps the molten material as close as possible to the mould cavity, significantly reducing the runner. This improves the consistency of the feed and reduces waste.

The direct injection mould eliminates the sprue. The molten material is injected directly into the part, reducing material loss and optimising production time.
