Durostone® PMP 325


Durostone®compression moulded parts

With modern presses and precise tools we produce the most varied FRP components and pressed parts from SMC and BMC-polyester products. In the SMC technique, a combination of resin and fibres is cured in a mould under pressure and heat. The production method enables time savings, high reproducibility and a smooth surface. The process is particularly suitable for medium-sized series.

With our presses we are able to produce pressed parts with dimensions of 150 x 150 x 150 mm up to 2,200 x 1,600 x 1,200 mm.
