Compression and transfer moulding

We supply compression and transfer moulded workpieces to a wide range of customers in the trade and we presently have 12 hydraulic presses and 2 transfer presses at our production plant.


Compression moulding is the simplest and oldest method for production of moulded rubber workpieces and is still very much in use. It is typically used in connection with large workpieces, with or without metal, with simple geometries and low requirements regarding dimensional tolerance and flashes.

Compression dies can be very simple and are used in hydraulic presses. The pre-shaped crude rubber material is inserted between the open, pre-heated die parts and the press then closes the die and forms the material. This moulding process is characterised by a longer
vulcanizing time and relatively much manual handling.Kompresionsstoebning2
Transfer moulding is a cross between compression moulding and injection moulding: Instead of being placed directly in the cavities of the die like with compression moulding, the crude rubber is placed in the transfer press chamber and then, by means of a piston, pressed out through the flow channels into the cavities.

A transfer moulding die normally has several cavities and is typically used for workpieces with a more complex
geometry, both with and without metal.
