四、新型塑料模具钢的热处理工艺规范 表3所列为新型塑料模具钢的热处理规范。 五、新型塑料模具钢的特点及应用 由于塑料制品的用途不断地扩大,对塑料制品质量要求更为突出,除要有一定强度、耐用度、抗老化性外,还要求塑料制品表面光泽,色彩鲜艳,图案清晰。而对塑料透明件,要求具有较高的透明度(透光率)和极小的光折射率。所有这些要求我们对塑料模具钢的特点和应用有一较全面的了解。
Fourth, the new plastic mold steel heat treatment process specifications listed in Table 3 for the new plastic mold steel heat treatment specifications. Fifth, the new plastic mold steel characteristics and applications As the use of plastic products continue to expand, the quality requirements of plastic products are more prominent, in addition to have a certain degree of strength, durability, anti-aging, but also requires the plastic surface gloss, color Bright, clear pattern. Transparent plastic parts, requires a higher degree of transparency (light transmittance) and a very small refractive index. All of these require that we have a more comprehensive understanding of the characteristics and applications of plastic mold steel.
