1、 Ultrasonic cleaning can remove oil, dust, and oxidation impurities from the surface of PVD coated products, ensuring the cleanliness of the surface of the product to be plated and improving the adhesion of the film substrate. In industrial production, ultrasonic cleaning of products under different surface conditions generally includes rough cleaning and fine cleaning. Coarse cleaning requires a very short time, just simple oil and rust removal ultrasonic cleaning for electroplating products, mainly targeting some products with already coated surfaces or requiring passivation; Fine cleaning takes a long time and requires the use of various functional tanks on the cleaning line to clean the products to be plated. After cleaning, the product can be directly installed on the substrate for coating preparation.

2、 There are generally three methods for deburring and removing burrs: manual cleaning, semi-automatic wheel brush cleaning, and glass bead sandblasting treatment. Manual cleaning is very suitable for handling burrs on hard alloy cutting tools. This is because its blade generally has fewer burrs, and even if there are, it is very hard and brittle. When using semi-automatic wheel brushes for cleaning and glass bead sandblasting, it is easy to damage the cutting edge. Semi automatic wheel brush cleaning is generally used for deburring of gear hobbing cutters, which involves fixing the cutter on a low-speed rotary table and pressing it onto the cutter teeth with a stainless steel brush for cleaning. However, this method has lower efficiency. Glass bead sandblasting and deburring is a widely used pre-treatment method in the coating industry. The equipment used is usually a dry sandblasting machine, and the sand material is glass beads. After deburring, the blade disappears and the teeth are clean, which is conducive to the deposition of coating material particles. 3、 Sandblasting is powered by compressed air to form a high-speed jet beam that is sprayed onto the surface of the workpiece to be treated, removing impurities, impurities, and oxide layers on the surface, achieving a certain level of cleanliness on the product surface, eliminating residual stress on the workpiece, and improving the surface hardness of the substrate. 4、 Passivation and passivation treatment is an important treatment process for chemical cleaning, which can prevent substrate corrosion. In addition, passivation treatment can also remove precision and high-precision tool edge burrs, clean large particles on the coated surface after plating, and polish the surface coating. Sand materials mainly include coarse sand and fine sand. 5、 Polishing and polishing refers to the process of using mechanical, chemical, or electrochemical effects to reduce the surface roughness of PVD coated products, thereby obtaining a bright and smooth surface. It uses polishing tools, abrasive particles, or other polishing media to decorate and process the surface of PVD coated products. The purpose of polishing treatment is to obtain a smooth surface or mirror gloss, sometimes used to eliminate gloss. Polishing wheels are commonly used as polishing tools. 6、 Degassing and degassing is the process of heating, insulation, and cooling the product to be plated using ultrasonic cleaning in a vacuum environment, so that the blind holes, gaps, welding holes, gaps, welding parts, and product surfaces of the product to be plated are not cleaned by ultrasonic cleaning. Oil stains and volatile materials evaporate under high temperature and vacuum conditions to ensure that the product will not be oxidized by impurities and gases during the coating process, resulting in coating film and even polluting the furnace chamber. 7、 There are generally two methods for coating removal: chemical coating removal and electrolytic coating removal, both of which clean the old coating by reacting the chemical solution with the coating surface. The chemical stripping solution is convenient and the equipment is simple, but the stripping speed is slow. Different types of coatings require specific chemical solutions to be effective. Electrolytic recoating can almost remove all coatings with a fast recoating speed, but the equipment cost is high and its economic and practical applicability is not as good as chemical recoating.

Early failures often occur during the use of molds. The factors of failure are usually wear, corrosion, fusion, adhesion, etc. The problem is not only delaying the production cycle, but also greatly increasing production costs, thereby affecting the competitiveness of enterprises. To this end, the industry has successively launched different solutions, and PVD coating surface treatment technology is a highly favored solution that can most effectively solve the above problems. The PVD coating process used for different molds (plastic molds, metal stamping molds, die-casting molds, mold accessories, forming molds, etc.) and high demand hardware products such as mechanical wear-resistant and corrosion-resistant parts can significantly improve the surface hardness, wear resistance, corrosion resistance, heat resistance, and lubrication of the product; And it can facilitate film removal, greatly improve the quality (such as surface roughness, wear resistance, accuracy, etc.) and service life of molds and parts, so as to effectively unleash the potential of the product.
