Injection ကိုစက်များအတွက်ဝက်အူ & Barrel
Function of screw and barrel. Conveying, compaction, melting, mixing and injecting plastic. All of these procedures are done through the rotation of the screw in the barrel.
Consist of screw and barrel. Generally screw and barrel for injection molding machine include screw, screw tip, thrust ring, seal ring, barrel, end cap, nozzle.
Material of screw and barrel
Generally, screws and barrels made of 38CrMoAlA (JIS SACM645) steel are used for processing most kinds of plastic, like PP, PE, ABS, PS, PA, etc. 38CrMoAl is a high-grade nitriding steel, which has very good quality of wear resistance and fatigue strength. After nitriding, the hardness of screw and barrel is around 900-1000HV. We have a lot size of raw material in stock.
Hardness After Hardening & Tempering: HB280-320
Nitrided hardness: 950-1100HV
Nitrided layer depth:0.50-0.80mm
Nitrided brittleness: Less than 2 level
Surface roughness: Ra 0.4μm
ဝက်အူ၏ Linear: 0.015mm / မီတာ
Bimetallic အလွှာနက်ရှိုင်း: ≥3mm
Bimetallic ခိုင်မာသော: HRC60-72
ခက်-chrome များတွင်လည်းကောင်း, ခိုင်မာသော nitride ပြီးနောက်: ≥950HV
Chrome-plating layer depth: 0.025~0.10mm.
Hard chrome plating
