The main reason for the defects in plastic service machining in the production of plastic parts is the injection of molds, industrial raw materials, etc. If the mold machining is poor, such as scars, wear, roughness, etc., it will also be reflected on the plastic parts, and the plastic parts will be shiny. bad. In this regard, the plastic service machining plant must carefully process the mold to ensure that the surface of the mold cavity is not rough, and if necessary, the mold can be polished and chrome-plated.
In the production of plastic service machining plants, if there are problems with raw materials, large differences in pigments, or uneven mixing of raw materials, it may cause poor gloss after injection molding of plastic products. For this reason, recycled materials or nozzles should be reduced. The addition of materials. Some raw materials can also cause poor gloss when baking temperature and adjusting temperature are not suitable. For this, raw materials with better temperature resistance should be selected and baked for sufficient time. In order to reduce costs, some plastic service factories have purchased raw materials mixed with foreign objects. If the foreign objects and the raw materials are uniformly mixed together to cause poor appearance, these materials should be excluded in advance to improve the gloss of the product.
