QPQ processing, which is an abbreviation of Quench-Polish-Quench, refers to the ferrous metal parts placed in two different salt baths, which penetrate into the metal surface to form a composite layer through various elements, thereby modifying the surface of the parts. the goal of. It has good wear resistance, fatigue resistance, corrosion resistance and small deformation; the process is applicable to steel materials, from pure iron, low carbon steel, structural steel, tool steel to various high alloy steel, stainless steel, cast iron Etc.; commonly used in various industries of prototype, precision parts, non-standard and large parts, especially in automotive parts, motorcycle parts, mechanical parts, machine parts, electrical switches, tools and tools are widely used. email@example.com
ZhuanXin Precision has more than 10 years of surface treatment experience, such as: anodizing, dusting, painting, Teflon spraying, electroplating, passivation, polishing, sandblasting, wire drawing, silk screen, laser engraving, electrophoresis, CD pattern, etching, High gloss, etched, blackened, QPQ treated, we are also very good at heat treatment.
Heat treatment refers to the metal heat treatment process in which the material is heated and cooled on the surface layer of the workpiece to change the surface structure of the workpiece to obtain the desired properties, and the comprehensive mechanical properties of the workpiece are improved. The heat treatment process can be roughly divided into integral heat treatment (annealing, normalizing, quenching and tempering), surface heat treatment (laser heat treatment, flame quenching and induction heating treatment), local heat treatment and chemical heat treatment (carburizing, nitriding, metal infiltration, compounding). Seepage) and so on. Commonly used in mechanical products, automotive products, motorcycle products, robot products, medical products, aircraft products, bicycle products and other industries, some shafts, gear links, bolts, gears and parts subject to variable load.
In addition to surface treatment, we are also very good at various processing techniques. We have more than 30 advanced processing equipments, which can customize your processing technology, such as: CNC milling, CNC lathe machining, wire cutting, electric spark, laser Cutting, CNC bending, stamping, drilling, tapping and other processing, 1~10000 pieces of prototype and precision parts can be customized, now send 3D/CAD files to us, get free quote within 2 hours.
