Many of our customers produce different ring stiffness classes to fulfill various market requirements. Our patented Mold Block Insert Technology enables them to produce them with one set of molds. For example, by changing only the mold inserts and cooling plug, optimized SN4 and optimized SN8 pipes can be made with only one set of molds.
It can be used also to optimize pipe profiles for the use of different raw materials.
Corma’s patented mold block insert system is available for pipe sizes from 400 to 3.000 mm o.d.
