• Aspheric glass moulding and thermoforming mould (mould sleeve)

Features and advantages

• It still has high hardness and mechanical strength at high temperature to avoid surface scratches during the molding process;

• Excellent surface processing quality, no air holes on the surface, smooth optical mirror surface, no adhesion to the glass, good demoulding performance;

• It has excellent oxidation resistance under high temperature environmental conditions, it will not react with optical glass under high temperature, and the surface quality is stable;

• High thermal conductivity, low thermal expansion, thermal shock resistance: withstand repeated heating and cooling cycles in the molding process, has long life;

• As the thermal expansion coefficient of silicon carbide is slightly lower than that of tungsten steel, it fits well with the tungsten steel mold core. It is more convenient to pick and place the mold. Extending the life of the mold core can greatly reduce product costs.
