Moulds

We are the only manufacturer specializing in welded moulds for plastic sheet production.
To date, we have produced more than 200 welded moulds, with our very first mould still operating reliably after more than 30 years in production.

Mould Designs

Our presses are equipped with moulds in bolted or welded design, available in various dimensions and heating options. They can be heated directly or indirectly using different heating media. Each mould is manufactured with a unique production technology developed through our in-house expertise.

With more than 30 years of experience in mould production for plastic sheets, we deliver solutions that ensure precision, durability, and consistent product quality.

Stamps

The stamp is used to press the product inside the mould and is fixed to the hydraulic press frame. It consists of three main components:

Heating plate: steel sheet with drilled channels for heating media.
Insulation: positioned between heated and supporting plates to minimize energy loss.
Supporting plate: robust steel sheet construction for stability.

For maximum reliability, the heating plate of the stamp is equipped with welded side barriers that prevent compressed material from entering the inner structure of the stamp.
