Product details：
1. It is suitable for continuous extrusion molding of general purpose plastics (pepppspvcpmmapcpapetabshipsgppseva).
2. Material: high quality alloy 38crmoala is selected from well-known domestic and abroad manufacturers.
3. Heat treatment: the raw material is treated by several heat treatment procedures such as quenching, tempering, qualitative, nitride treatment, etc. To achieve the technical requirements of hb≥280, nitride hardness (hv)≥980, nitride thickness between 0.45mm and 0.65mm, nitride frangibility≤class 2.[]
4. New materials: skd61, 42grmo, 9cr18mov, etc. Treated by vacuum quenching or medium frequency quenching, etc.
5. Special process: to meet the products’ requirements of abrasion performance and corrosion resistance from different customs, the screw is spray welded by alloy or plated by hard chromium according to the practical situation.
