Compression Moulding ideal for low volume production rubber parts.
From prototype to production, compression moulding in China provides a cost effective, high quality solution.
The advantage of prototyping parts designed from rubber or flexible elastomers such as silicone, is that it enables you to confirm the required rigidity of the material. However, prototyping options are quite limited and the quickest option is to 3D print rubber or other flexible parts. Whilst this alleviates the need for tooling, little can be done to improve the layered surface finish.
An alternative option we can offer is to use vacuum casting and produce custom flexible parts in an elastomeric polyurethane. This can provide prototype options of Shore A hardness' ranging from 15 (simulating soft rubber) to 95 (simulating hard rubber). Surface finish is dictated by the silicone tooling and aesthetically pleasing parts can be produced.
Shore Hardness comparisons can be seen in the chart below. There is more information on selecting hardness in our FAQ article here.
If higher volume quantities are required, or functionality demands production intent materials, a range of rubbers such as EPDM, Viton, Neoprene, Nitrile and Silicone can be moulded by aluminium development tooling, or full production tooling.
You might find some of the FAQs we've included about flexible materials, custom rubber parts and Shore hardness useful. You can find them here.
Produces production intent material properties. Injection Moulding is used for development as well as production parts.
Compression Moulding is a great process that is commonly used for thermoset materials, such as silicone and a variety of rubbers.
Ideal for producing small quantities of plastic and flexible rubber parts, especially if aesthetics are important.
Selective Laser Sintering (SLS) is the second most commonly used process after Stereolithography (SLA). SLS parts can be produced with high functionality in very short lead times.
Offering one of the largest ranges of materials, Polyjet can produce hard, flexible and multi material parts.
Extrusion is a manufacturing method where long lengths of the same cross section can be produced quickly and repeatedly.
