Nickel Plated Screw

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
In the case of PE parts defibrillators does not exceed 30% of
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
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.
