PWDS, 3DX "Deformable Die" Systems
As experts in parison programming systems it was only a matter of time before we would produce radial thickness control systems. Originally called PWDS by the inventor Harald Feuerherm, the system comprised of a flexible steel die (aka bushing) squeezed into a series of shapes as the parison emerged. This gave a much greater degree of wall thickness control and became almost mandatory for complex shapes such as automotive fuel tanks. It is also extensively used on U.N. drums and jerry cans. Our 3DX system uses the same principle as the original PWDS. With the benefit of fresh thinking, new steel alloys and integrated electronics we feel that our product has many advantages over the original PWDS. Our 3DX system can be supplied with new machines or retrofitted to your existing machine. If retrofitted, we don't care what make of machine, or head design you have. All we ask is that the machine is capable of producing good quality parts that generally meet your requirements. Our 3DX 'deformable die' ring will then optimize the radial thickness to reduce container weight and optimize thickness distribution. With typical material savings of 10% on 'L' ring drums, payback under 12 months is very typical.
