Compression / Compression moulding

Press moulding with mould tools

This production method is the simplest when using a mold tool. It is suitable for small series production, as well as large products where injection volume in an injection machine is not a concern.

The first step is to manufacture rubber blanks that will be used to load the tool.

You place a rubber or silicone blank directly into each cavity. Start the press, which compresses the tool. The part vulcanises in the heat and, after the specified time, the machine opens and the part can be removed. Much like making waffles!  Rubber conducts heat poorly, so the vulcanisation time is longer when working with transfer or injection. The tools/moulds are normally somewhat less expensive.

Mold manufacturing

We support you every step of the way, from drawings and/or 3D files to a fully functional mold tool for compression, transfer, or injection molding, using most common rubber or silicone materials.

Injection

The best way to manufacture a molded rubber or silicone component is through injection molding. The tool remains closed during the process, resulting in less flash.

Transfer molding

In transfer molding, one or more pre-formed blanks are placed in a pot. The press is then closed, and a plunger descends into the pot, forcing the rubber through a series of holes.
