Manufacturing processes

Generally there are two different manufacturing processes for the production of elastomer O-Rings possible.

• Compression process
(Compression moulding = CM process)
• Injection moulding
(Injection moulding = IM process)

In CM the slug is manually inserted in the tool (mould) before the two mould halves consisting of an upper and a lower part are closed. As this process is very time-consuming, it is primarily suitable for manufacturing smaller quantities and larger dimensions.

In injection moulding the slug is automatically injected into the tool, which contains several O-Ring cavities. This process is particularly suitable for large quantities and small dimensions.
