Metal stamping manufacturer, stamping parts surface treatment technology + 16 quality inspection manufacturers [hardware]

Metal stamping manufacturers, in order to delay metal oxidation and rust, while taking into account the appearance, texture, function and other requirements of the product, they will carry out some post-processing treatments on the metal surface of the stamping parts. Xiaoshuo will take you to understand some of the common ones. Processing technology: 1. Common mechanical surface treatments include polishing, sandblasting, shot blasting, wire drawing, etching, etc. Mechanical surface treatment is mainly to improve the appearance and texture of the product. For example, polishing is to polish the metal surface. After polishing the stainless steel stamping hardware product, it can achieve a mirror effect. Sandblasted stamping hardware products have a matte effect. 2. Electrochemical surface treatment Common electrochemical surface treatment methods in the stamping hardware industry are electroplating and electrophoresis. Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. Electrophoresis is the electrophoretic coating at the anode and the anode. Under the action of voltage, the charged coating ions move to the cathode, and form insoluble matter with the alkali generated on the cathode surface to deposit on the surface of the workpiece. They can enhance the corrosion resistance of metals (corrosion-resistant metals are mostly used for coating metals), increase hardness, prevent abrasion, improve conductivity, lubricity, heat resistance, and surface aesthetics. 3. Heat treatment Common heat treatment methods include hot-dip galvanizing, blackening and baking varnish, all of which require treatment of the metal surface at high temperatures. Hot-dip galvanizing is a surface treatment technology in which a layer of zinc is plated on the surface of metals, alloys or other materials in a high-temperature solution containing zinc ions for aesthetics and rust prevention. Blackening is to rapidly oxidize the surface of steel products at high temperatures to form a dense oxide film protective layer and improve the anti-rust ability of steel parts. Baking paint is to put primer and top coat on the substrate, and send it to the dust-free and temperature-controlled baking room for baking every time the paint is applied. The heat treatment of stamping hardware products can generally take into account the ability of rust prevention and beauty. Hardware, 15 years of experience in metal stamping manufacturer, custom production of 20000+ sets of stamping dies, stamping accuracy can reach 0.01mm, 16 quality inspections are strictly controlled. It can ensure that the precision and quality of some products processed by stamping parts are up to standard.
