Injection Support Pillars High Pressure And Hardness Alumina Zirconia Ceramic Injection Molding Pillars
The Support pillars is a mold part installed between the spare plate and the rear clamping plate of the mold. They greatly increase the mold capacity to support the projected cavity area and prevent deflection under injection pressure. Without sufficient support, bifurcation line surfaces may flicker and plate bending may occur.Support pillar vendors can help determine the number of pillars required for a particular application.
The ceramic support pillars from high-performance technical ceramic materials, including alumina, zirconia, and silicon carbide.with excellent wear resistance, high hardness, good insulation, low friction, chemical resistant , resistant high temperature , thermal shock resistant and so on.
The main materials of the injection ceramic pillar:
· 95%--99.99% Alumina (Al2O3)
· Silicon Carbide
· Silicon Nitride
· TTZ: Magnesia partially stabilized Zirconia (ZrO2)
· YTZP: Yttria partially stabilized Zirconia (ZrO2)
· ZDY: Yttria fully stabilized Zirconia (ZrO2)
Specifications
Support pillars have either tapped holes or drilled and counter bored holes for mounting a locating pin. For support pillars with tapped holes, product specifications include:
-Outside diameter (OD)
-Tap diameter
-Dowel locating hold diameter
-Length
The length, thickness , diameter and shape of the ceramic plates are customized.
Application
Support pillars for plastic injection molding, is the most common plastic processing method.The injection molding machine reduces the pelletized material to a hot liquid or melt, which is then forced into the cooling mold under great pressure...
Delivery:
Custom OEM will be shipped within 15 days after determining the parameters
The samples will be shipped within 3 days
Quick Delivery Via Fedex,DHL,UPS,TNT Etc.
