Injection Moulding

Parts shipped in 1 to 15 days

What is injection moulding?

Injection moulding is the most common form of manufacture, suitable for prototyping, bridge tooling and low-volume production of end-use parts. The process relies on a mechanism that injects thermoplastic or thermosetting polymers into a mould cavity, which then solidifies into the finished part before being ejected from the mould.

What are the advantages of injection moulding?

At Protolabs we offer rapid injection moulding with quick turnaround times to help reduce design risks and limit overall production costs. Our automated processes begin with data being sent directly to the mills, enabling us to produce rapid prototypes and end-use production parts in as little as 1 day. Moreover, our high-grade aluminium mould tools come with a lifetime guarantee and we stock hundreds of thermoplastic resins and liquid silicon rubber materials.

Plastic Injection Moulding

Plastic injection moulding is a manufacturing process where thermoplastic resin pellets are fed into a heated barrel, from which the now molten material is shot into the mould cavity. Injection times are often under one second, during which even predicted shrinkage through cooling is compensated. Once the desired cooling has been achieved the solidified production-grade part is ejected with an array of pins as the A-side and B-side of the mould separate. The two sides then close again for the process to be repeated.

Liquid Silicone Rubber Moulding

Liquid silicone rubber moulding is a thermoset process that mixes a two-component compound together, which is then heat cured in the mould with a platinum catalyst to produce a final LSR part.

Overmoulding & Insert Moulding

Overmoulding and insert moulding are two-part injection moulding processes where one material is overlaid onto a second substrate part or metal insert to create a single multi-material component.
