PPS材料注射成型工艺

◆桶

为了防止材料氧化和变色，温度不应过高。流动性能满足型腔的顺利填充。模具温度通常为310-340℃。大部件使用较低的筒体温度，小部件使用较高的温度。桶的温度

◆材料喷嘴温度建议在不浇铸的情况下保持材料的良好流动性

◆模具温度通常以140-170℃为宜

◆注射压力

高注射压力的PPS产品更好，尤其是复杂薄壁零件，注射压力的增加对成型的负面影响更小。注入压力通常为80-150Mpa

◆注射速度

注射速度越快，产品的表面光泽度越好，但容易产生产品翘曲、边缘溢出和烧焦，因此一般采用中等注射速度

PPS material injection molding process

◆Barrel

In order to prevent the material from oxidizing and discoloring, the temperature should not be too high. The fluidity can satisfy the smooth filling of the mold cavity. The mold temperature is usually 310-340℃. The large part uses a lower barrel temperature, and the small part uses a higher temperature. The temperature of the barrel.

◆Material nozzle temperature

It is advisable to maintain good fluidity of the material without casting.

◆Mold temperature

Usually 140-170℃ is suitable.

◆Injection pressure

PPS products are better with high injection pressure, especially complex and thin-walled parts, and the increase in injection pressure has less negative impact on molding. The injection pressure is usually 80-150Mpa.

◆Injection speed

The faster the injection speed, the better the surface gloss of the product, but it is prone to product warping, edge overflow and scorching, so the medium injection speed is generally used.
