In the coating deposition process, so that a coherent coating with superior product substrate, and can effectively control the deposition thickness of the coating (0.5 microns ─6 unilateral micron), process for the coating of different product types. After PVD tool also has a thermal stability of CVD after enabling tools (Broach, cutter, wire tapping, drill, knife tablets, points in the rod, etc.) of strong and efficient processing, it has excellent performance. Mold, mold accessories and mechanical parts for different classes of mold (plastic mold, metal stamping die, die casting mold ,, molding, extension of the mold, tensile modulus, flanging die, etc.) and mold parts (punch, thimble ), mechanical abrasion, corrosion-resistant parts, high requirements for PVD coating processes used in metal products, can significantly improve product surface hardness, wear resistance, corrosion resistance, heat resistance and lubricity; and to facilitate stripping greatly enhance the mold, the quality of the parts (such as surface roughness, wear resistance, accuracy, etc.) and life to effectively play the product's potential. Medical equipment, metal hardware products category PVD coating technology can be widely used in various types of wear, bite, corrosion, adhesion, fusion caused by the failure of tools, dies, machinery parts, medical equipment. Wherein, due to wear caused by failure of the product (such as: blanking, cold forging, powder molding, etc.) after the life of the coating can be increased by 2-20 times; strain caused by the bite of the products in question, or the mold (such as: extension mode, tensile modulus, flanging die, etc.), can be fundamentally resolved after coating. PVD coating suitable material: bearing the heating temperature is greater than 230 degrees unaffected metal material. Application examples: Die Name coating type mold material is processed material effect tool class TiN (Titanium Nitride) SKD11 0.5mm stainless steel increased by more than 9 times punch mold parts TiN (Titanium Nitride) Cr12MoV carbon steel increased by more than five times the powder metallurgy mold CrN (chromium nitride) DC53 WC + Co powder increased by more than 12 times the tensile mold TiCN (titanium carbonitride) SKD11 low carbon steel resolve molds, die casting mold strain problem AlCrN (aluminum chromium nitride) H13 aluminum alloy 6063 to solve the sticky aluminum material phenomenon, extend die life nano PVD coating usually title: titanium, ion plating, vacuum plating, coating, nano-coating, coating, etc.
