Wide range of customized solutions

Mould design, engineering, extrusion and co-extrusion, R&D+i, raw material and colorant formulating and special finishes

Our company’s 30 extrusion lines of different sizes and technologies allow us to quickly produce different types of extruded and co-extruded profiles using a wide variety of polymers available on the market.

We draw on our vast experience to develop dedicated projects using imaginative, effective applications from several sectors to adapt commonly used processes to the special needs of our customers.

We rely on our own facilities to develop our comprehensive design and production process, including mould design using electro-erosion as well as mould maintenance and safekeeping. We adapt market-ready raw materials, formulations and colorants in our laboratory, where we work with all kinds of plastics, from conductive to biodegradable, in a constant search for new solutions that includes collaborating with different European research programmes.
