对于护坡模具材料的选择是要有所的注意,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。

For the selection of slope protection die materials, attention should be paid to, first of all, 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, durability and modulus of elasticity of www.huganqi.org.cnwww.xiaoyuandiaos.com.cnwww.qinhuandaobaojie.cnwww.diandongmenq.cn

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.
