一.混料工艺：
I. Mixing process:
回料加木粉和轻钙混到110度打开高混机大盖1分钟左右加pa-02和HD3304//HD3303混到125-135度左右放入泠缸泠却到40度制粒。
Mix wood flour and light calcium into 110 degrees. Open the cover of the high mixer for about 1 minute. Mix pa-02 and HD3304//HD3303 into 125-135 degrees. Put them in a cold bowl and cool them to 40 degrees for granulation.
二.制粒工艺：
2. Granulation technology:
1.最好采用混炼塑化效果好的锥双或平双制粒。
1. It is better to use conical or flat double granulation with good mixing and plasticizing effect.
2.制粒的基本温度如下：
2. The basic temperature of granulation is as follows:
（160-170度）—（160-170度） —（165-175度）—（175-185度）—（190-200度）—（200-220度）温度设定顺序为摸头到下料，具体温度要据设备及粒子的质量来定，胶粒必须是表面光滑，不粘料，结实，胶粒大小和长度一致，无粉尘。
(160-170 degrees) - (160-170 degrees) - (165-175 degrees) - (175-185 degrees) - (190-200 degrees) - (200-220 degrees) temperature setting order is to touch the head to blanking, the specific temperature depends on the quality of equipment and particles, the particles must be smooth surface, non-adhesive, solid, size and length of particles consistent, no dust.
三.注塑：
3. Injection Molding:
1.注塑机无需做大的改变但喷嘴比注塑非木塑产品改大20%-30%左右。
1. The injection moulding machine does not need to be changed greatly, but the nozzle is about 20%-30% larger than the injection moulding non-wood products.
2.模具的浇口如产品厚度不一最好设在最厚处。
2. The gate of the die, if the thickness of the product is not the same, should be set at the thickest place.
3.WPC木塑注塑制品厚度务必在1.5-2mm以上，制品太薄不利于生产和影响制品质量。
3. The thickness of WPC wood-plastic injection products must be above 1.5-2 mm. The product is too thin, which is not conducive to production and affects the quality of products.
