KH Screw construction and special characteristics KH is attached to the metal core (SCM440) using the reactive sintering method. Thanks to this processing method KH is not only covering the surface of the screw- screw flights are actually 100% made out of it.As a result- the screw can last extraordinarily long even against resin materials like plastic magnet (high abrasion) or halogen-free resins(extremely corrosive). KH Cylinder construction and special characteristics 4 mm thick KH inner tube is attached to SCM440 metal outer tube by shrinking process.4mm thick layer of hardened material is much more than in case of products from other manufacturers. Due to this characteristics - KH products shows extraordinary durability against abrasion and therefore is very recommended to use with resin materials containing high percentage of Glass Fiber or other highly-aggressive types of resins.Moreover - thanks to using the shrinking process- inner tub is being pressurized from outside. It makes it very strong against any pressure pushing from the inside and conse-quently makes KH cylinder very recommended for clients working with very high injection pressure in their process
