Hewitech - Model - Drainage Box Brochure

Over 20 years ago Hewitechdeveloped the first welded film cooling fills in PP –shaped, extruded films in a single step from the melt. Films with a thickness distribution lead to high-strength blocks –with sharply reduced material input! Deformation of flat films is history. Today Hewitechmanufactures not only film cooling fills of PP but also of welded PVC –free of adhesives and solvents.
