护坡模具材料选取
首先是要选择高耐磨性的,这是避免塑料质量的影响,防止出现钢材的导热性不足可用冷却系统来补偿,而塑料模具它的硬度、耐用度和弹性模量较低,特别更显重要是在加工半结晶性热塑料件时。还有,一般要对模腔进行抛光处理,抛光性能好模具行腔内壁要求很高,表面越亮越好,粗糙度非常小,因此要求模具材料易于抛光,模具等材料不应该有气孔、杂质等缺陷。高精度护坡模具具有线条流畅,圆顺,拼缝紧密的特征

The first is to choose high wear resistance, which is to avoid the impact of plastic quality, to prevent the lack of thermal conductivity of steel can be compensated by cooling system, while the hardness, durabilitygangguanl.37ix.com.cnzhimaig.37ix.com.cnsujiao.07858.netwulumuqi.89ix.comlanzhou.89ix.com

xian.89ix.comand modulus of elasticity of plastic mould are low, especially when processing semi-crystalline thermoplastic parts. In addition, it is generally necessary to polish the die cavity. The better the polishing performance, the better the surface, and the smaller the roughness. Therefore, it is required that the die material is easy to polish, and the die and other materials should not have defects such as porosity and impurities. The high precision slope protection die has the characteristics of smooth lines, smooth circles and tight joints.
