高光注塑成型工艺对ABS塑件表面硬度的影响

Influence of Rapid Heating Cycle Molding Process on Surface Hardness of ABS Parts

基于高光注塑成型工艺实验平台,进行了丙烯腈-丁二烯-苯乙烯共聚物(ABS)注塑成型工艺实验,分析了工艺参数对塑件表面硬度的影响。结果表明:模具温度对ABS塑件的表面硬度影响最为显著。在一定温度范围内,随着模具温度的升高,ABS塑件的表面硬度不断增大,而当模具温度超过110℃时,ABS塑件的表面硬度则开始快速降低。

Based on the rapid heating cycle molding process platform, the influence of molding process parameters on surface hardness of acrylonitrile butadiene styrene（ABS） parts was studied. The results show that the mold temperature is the most significant process parameter that can affect surface hardness of the ABS parts. In a range of temperature, the surface hardness of ABS product raises along with the improvement of mold temperature. However, as the mold temperature increases beyond 110℃, the surface hardness of the ABS parts will decrease rapidly.
