The purpose of plastic molding is to use all possible conditions based on the original properties of the plastics, making it a product having application value.

The plastic molding process has extruded molding, injection molding, calendering forming, molded forming four categories. Plastic molding is to melt the plastic heating, by molding a die or mold, cooling to a solid form after the shape of the desired shape, becoming the final product.

Multi-molding methods of plastic, different forming methods have a large difference in processing temperature:

1. For the same variety, it is different if its processing process is different, the processing temperature will also differ. As a variety of LDPEs are used for hose molding, the temperature is 120-140 ° C, and the extrusion temperature is 170-205 ° C in the blown film molding process, and the temperature is delivered at a temperature of up to 285-300 ° C. Therefore, the same plastic is also different from the heat resistance requirements of the pigment during different forming processes.

2. Different molding processes of plastic are different from the dispersibility requirements of the toner. Spinning, cast film, communication cable machining process relate to pigments, especially the ultra-thin fifth requirements. If the pigment dispersibility is poor, the filter is blocked, and the wire is broken and affects normal production. The molding process is relatively low for the dispersibility requirements of the pigment.
