Raw materials for plastic products are mainly available in the domestic market as follows (examples of some raw materials):
PP-injection molding polypropylene: low transparency, low gloss, low rigidity, but has stronger shocker strength, commonly used in plastic buckets, plastic tubs, folders, drinking straws and so on.
PC-injection molding polycarbonate: high transparency, high gloss, very brittle, commonly used in water bottles, cups, milk bottles and other plastic bottles.
ABS：The resin is one of the five major synthetic resins and has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance, injection molding and electrical properties. It also has the characteristics of easy processing, stable product size, good surface gloss, etc., mainly used in milk bottles, cups, cars, etc.
PE: The main products are mineral water bottle caps, PE freshness mold, milk bottles and so on.
PVC: Mainly used for plastic bags, packaging bags, drainage pipes, etc. The PVC plastic injection molding is very important to produce high-quality PVC materials.
PS: Mainly used for printer shell, electric appliance shell, etc.
All plastics come in all sorts of colors. And this color is all blended out with pigments, which is the technical core of plastics. If the colors are well-matched and the merchandise sells very well, the owner will also value the privacy of the color match.
In general, the raw materials for molded plastic products are mixed together. For example, ABS has good gloss, PP has good resistance to shocks, and PC has high transparency, so new products are created by using the characteristic mixing ratios of each raw material, but such products are generally not used for food utensils.
Today's molded plastic products are made by injection molding or blow molding, so every time you design a sample, you have to open a new mold. And molds generally range from tens of thousands to hundreds of thousands of dollars, so in addition to the price of raw materials, the cost of the mold is also very large. There may be many parts to make a finished product, each of which requires a separate mold.
