产品性能：

1、塑料处理

PC/ABS吸水性小，一般为0.2%-0.5%。在通常情况下，PC/ABS不需干燥就能加工，但对潮湿原料必须进行干燥。干燥温度80℃以上，时间2小时以上，具体应按供应商资料进行。

再生料使用比例一般不超过20-30%。但要视产品的种类和很终用途而定，有时可达。

2、塑机的选用

PC/ABS除了要求螺杆无滞料区外，对注塑机没有特别要求，一般注塑即可。

3、模具及浇口设计

常见模具温度控制为80-90℃，流道直径有3-6mm，浇口长度为0.5mm，浇口大小要视胶壁厚度而定，圆形浇口直径至少应制品厚度的0.5-0.6倍，长方形浇口的宽度通常是厚度的2倍或以上，深度为壁厚的0.6倍，脱模斜度40′-1°30′之间。

排气系统

PC/ABS-H 厚度0.01-0.02mm宽3mm

PC/ABS-C 厚度0.04mm宽3mm

4、熔胶温度

可用空射法量度

PC/ABS-H 可设为215℃ （190℃-230℃）

PC/ABS-C 可设为205℃ （190℃-210℃）

5, injection speed is usually medium speed, too slow easy toproduce ripple, too fast easy to produce striae and shearoverheating. 6. The lower the back pressure, the better, generallynot more than 200bar7, retention time if the equipment does nothave melt retention point, pC / ABS-H can stay at 215 °C for 35minutes. PC / ABS-C can stay at 205 °C for 20 minutes withoutserious decomposition. At injection temperature, melt can not stayin the barrel for more than 20 minutes. PC / ABS-C can stay for 7minutes at 240 °C. If shutdown, barrel temperature can be reducedto 150 °C, if long-term shutdown must clean the barrel, turn offthe heater. 8, stop cleaning machine barrel must use PE or PP, turnoff the electric heating, push the screw in the front. The cylinderand screw must be kept clean. Impurities or dirt can change theoverheat stability of PC / ABS (especially PC / ABS-h) . So whenthe use of halogenated polymers or other acidic polymers, theapplication of Pe clean-up can play PC / ABS material, otherwisethere will be an explosion. If the inappropriate role of pigments,lubricants or materials containing GF Nylon, will lead todegradation of plastic. 9, post-treatment for the use of parts atvery high temperature and high quality requirements, to carry outheat treatment. The effect of annealing treatment, the product canbe put into 30% hydrochloric acid solution for 30 minutesinspection, and then visual inspection to determine whether thereis residual stress crack.
