Product design: Plastic product processing holds rounding and increases the demolding slope. Mold: 1. Mold surface polishing. 2. Pull the white status growth thimble. 3. Confirm that the parting surface has no inverted buckles and air spurs, and repair it with oil stone. Injection molding process: 1. Under the premise of thorough filling of the clad product, accept the lowest possible injection pressure. 2. Confirm that there is no problem with the size and appearance of the product, reduce the holding pressure, holding time or cancel the holding pressure. 3. Adjust mold temperature and cooling time. When we are in the injection molding of plastic finished products, we usually encounter the idea of product whitening, we can first analyze the whitening from the methods of man, machine, material, method and ring, and classify and summarize all the components that affect the product; Re-examine the process opened up by the product.

Injection molding processing from plastic particles to molding injection molding products needs to go through a series of rigorous processes, and the lack of mastery of any process in the middle will lead to product quality problems, which are shared as follows.

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

PMMA plexiglass material is characterized by low melting point, easy shrinkage, brittleness, and intolerant of organic solvents. PMMA material is used in the valve body, which has high transparency, easy observation, and high cost performance. It is a very commonly used material.

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.

Polishing processing is a processing technology for surface modification when machining shaft precision parts, and this processing method should also pay attention to beauty and practicality. Simple shaft polishing refers to a method of modifying the surface of the workpiece with a file, emery cloth, and sandpaper.
