HIPS的工艺特点：

由于HIPS分子含有5-15%的橡胶，流动性受到一定程度的影响，因此注射压力和温度最好更高。鉴于其冷却速度比PS慢，需要足够的保持压力、保持时间和冷却时间。其成型周期略长于PS，加工温度通常为190-240°C。HIPS树脂吸水非常缓慢，因此通常不需要干燥。有时会吸收材料表面过多的水分，从而影响最终产品的表面光洁度。但是，可以通过在160°F下干燥2-3小时来去除多余的水分。HIPS产品也有一个特殊的“白边”问题，可以通过提高模具温度和夹紧力、降低保持压力和时间等来改善，但产品上的焊缝非常明显

Process Characteristics of HIPS:

Since the HIPS molecule contains 5-15% of rubber, the fluidity is affected to some certain extent, so the injection pressure and temperature are preferably higher. In view that its cooling rate is slower than that of PS, sufficient holding pressure, holding time and coolingtime are required. Its molding cycle is slightly longer than that of PS, and the processing temperature is usually 190-240° C. The HIPS resin absorbs water very slowly, so drying is generally not required. Sometimes excessive moisture on the surface of the material will be absorbed, which will affect the surface finish of the final product. But, excessive water can be removed by drying at 160°F for 2-3 hours. There is also a special “white edge” issue with the HIPS products, which can be improved by increasing mold temperature and clamping force, and reducing the holding pressure and time, etc., but welding lines is quite obvious on the product.
