• Mould clamping force: 250-3200T
• Shot weight: 30-80000G
• Screw can be matched with different heads, and barrel can be matched with different nozzles.
• Screw tip ( Screw head ), check valve, ring, barrel head, and flange, nozzle.
• Material: 38CrMoAIA, Nitriding treatment, The surface hardness: HV≥950
• Depth of nitriding layer: 0.5-0.9mm
• Material: Special alloy steel, after vacuum quenching and other heat treatment process, can greatly prolong the service life of three small pieces.
• We can design screw according to customer's raw material,such as PA,PA66,ABS,PP,PE,with or without Glass Fiber.
• We can also advise customer the suitable material to make screw barrel according to percent of Glass Fiber mixed with material.Such as 38CrMoAlA,SKD61,DC53,SKH55 and so on.
• Screw will be bimetallic treatment with Ni-60 alloy powder by spray or PTA technology.
