Quality Control
1.Materials Control:
All the materials are purchased from the domestic brands of Eurpean twin screw specialty materials suppilers, which tested by elemental analysis and metallurgical inspections to ensure the quality.
2.The internal splines is checked by the spline plug to ensure interchangeability of the elemets
3.All components are machined by CNC machines to ensure the shapes and tolerances of the elements.
4.Adopt the European high speed steel powder processing technology, and to the heat treatment according to the strict heat treatment process to ensure the wear and corrosion performance same as the foreigh brands.
5.Professioal technical team can not only provide timely and accurate mapping sample design but also the combination of elements of technical services
6.There are various prepared technical information and fitxtures for the various brands extruders to ensure the timely lead time. The common components have a lot of stock,even the new one, it can be delivered within 45days.
7.The modern management system can ensure the product 100% qualified and tracked.
