Injection mold products wall thickness recognition of polystyrene

Injection mold processing good liquidity of polystyrene, easy forming, because of the polystyrene melt viscosity on the shear rate and temperature are sensitive, so in the injection, both increasing the injection pressure rise or barrel temperature can make the melt viscosity drop, all can reach the purpose of improving polystyrene melt fluidity, which improve the effect of barrel temperature is more obvious. So some injection mould enterprises adopt the injection to the original, recognised by experts.

Injection mold products wall thickness is have certain effect on liquidity, PS melt the maximum flow length and the ratio of wall thickness of 200:1, so injection mould generally choose between 1.0 ~ 4.0.
