  1. Zhoushan Changjia Plastic machinery Co.,Ltd. Square Parallel Twin Alloy Barrel Material：W6Mo5Cr4V2、38CrMoAlAandPowder alloy composites Use：Masterbatch, modified, extruder, granulator equipment Processing range：Ф20mm - Ф300mm Service: In the case of PE parts defibrillators does not exceed 30% of the normal operation of 4000 hours Mandrel is an important element to ensure the smooth operation of the extruder, so we will make several tests each combination of bits in order to ensure to achieve tolerances. Years of experience in processing so that we can supply to 6 m long mandrel. 40CrNiMo mandrel made of material at high speed, high torque, high load, in particular good toughness and mechanical properties, in the process strictly controlled precision to ensure the mandrel groove depth, groove from standard surface smooth, tough and durable. Also based on customer requirements, providing customers with high wear resistance, high corrosion resistance of powder high-speed steel and other specialty steel products.

  2. Nickel Plated Screw Modification hardness: HB280-320 Nitriding hardness: 950-1100HV Nitriding depth: 0.50-0.80mm Nitriding brittleness: ≤ 2 Surface roughness: Ra 0.4 μm Screw Straightness: 0.015mm / m Alloy layer hardness: HRC60-72 Alloy layer depth: ≥ 3mm After the nitriding surface hardness: ≥ 950HV Chromium layer thickness: 0.025 ~ 0.10mm Screw type: For different formulations and products, screw can be used: ordinary type, pin type, barrier type, separation type, exhaust type and so on. Injection molding machine small pieces 1, Material: 38CrMoAl A nitriding, surface hardness: HV ≥ 900 Nitriding depth: 0.5-0.8mm 2, material: special alloy steel, after vacuum quenching and other heat treatment process, can greatly improve the service life of three small pieces
