Mold temperature refers to the mold cavity surface temperature in contact with the product during injection molding. Because it directly affects the cooling rate of the product in the mold cavity, and thus has a great influence on the intrinsic performance and appearance quality of the product. In this paper, five points of influence of mold temperature on quality control of injection parts are discussed. The content of the package material system for excellent products is adopted for friends' reference

The code name (UR) is made by the polymerization of polyester (or polyether) and diisocyanamide lipid compounds. Its chemical structure is more complex than that of general elastic polymers. In addition to the recurring carbamate groups, the molecular chain often contains groups such as ester groups, ether groups, and aromatic groups.

The prerequisite for the success of plastic molds is mainly reasonable plastic mold design. The design of plastic molds is relatively important, and the same structure can be produced in multiple ways.

Barrel temperature: The temperature that needs to be controlled during the injection molding process includes barrel temperature, nozzle temperature and mold temperature. The temperature of the first two passes mainly affects the plasticization and activity of the plastic, while the latter temperature mainly affects the activity and cooling of the plastic. Each kind of plastic has a different activity temperature, the uniform plastic, because of the source or grade difference, its activity temperature and differentiation temperature are different, this is because of the equilibrium molecular weight and molecular weight dispersion difference, the plasticization process of the plastic in the injection machine of the different example is also different, so the temperature of the selected barrel is not similar.

PPSU is a slightly amber linear polymer. In addition to strong polar solvents, concentrated nitric acid and sulfuric acid, it is stable to general acids, alkalis, salts, alcohols, aliphatic hydrocarbons, etc. Partially soluble in ester ketones' aromatic hydrocarbons, soluble in halocarbons' DM. Good rigidity and toughness, temperature resistance, heat oxidation resistance, excellent creep resistance, corrosion resistance of inorganic acids, alkalis and salt solutions, ion radiation resistance, non-toxic, good insulation and self-extinguishing properties, easy to form and process.

Treatment method of whitening in the processing of plastic products Product design: Plastic product processing holds rounding and increases the demolding slope. Mold: 1. Mold surface polishing.
