Product name: PC/PMMA SPECIALIZED SCREW BARREL
Introduction
Polycarbonates plastics are among the strongest, toughest, and most rigid thermoplastics. In addition, they have a ductility normally associated with the softer, lower-modulus thermoplastics. They are transparent materials and resistant to a variety of chemicals. The creep resistance of these plastic materials is among the best for thermoplastics.
MATERIAL PERFORMANCE:
1. Thermostable
2. Viscosity
3. Non-crystalline material
4. Hydrophilic(high temperature)
Material Selection
While Selecting the steel material for this kind of processing, we must take into consideration of the plastics different requirement, and chrome-plated is commonly recommended, also stainless steel is another good choice for this kind of appliance
Appliance
1. Electical & electronics
2. Construction Industry
3. Automobile industry
Like safety shields, lenses, glazing, electrical relay covers, helmets, pump impellers, headlights, interior aircraft components, telephone switchgear, snowmobile components, boat propellers, and housing for hand-held power tools...
