Steel: Includes varieties such as carbon steel (C1008 - C1010, S50C), stainless steel (304, 316, 410, etc.), and spring steel (SK5 - SK7). Carbon steel provides cost - effective strength; stainless steel delivers enhanced corrosion resistance for harsh environments; spring steel offers elasticity for vibration - damping scenarios.Manufacturing Processes
Precision Stamping: Leverages advanced stamping presses with tonnages ranging from 20 to 400 tons. Processes like blanking, bending, deep drawing, and coining are used. Progressive dies enable high - volume production with tight tolerances (down to ±0.01 mm for linear dimensions, ±1° for angular tolerance) and consistent part quality.
CNC Machining: Employs CNC milling, turning, drilling, etc., guided by CAD/CAM technology. This ensures complex geometries (custom slots, holes, or contours) are produced with extreme precision, minimizing human error and enabling repeatable accuracy for small - batch or highly customized orders. Dimensional & Quality Precision
Tolerances: Linear tolerance reaches ±0.01 mm (0.0004"), angular tolerance is ±1°, and minimum spacing between holes can be as low as 0.5×material thickness. Surface roughness is customizable, ranging from Ra 0.2 μm (mirror - like finish) to Ra 3.2 μm (standard finish).
Quality Control: Complies with standards like ISO 9001:2015, IATF 16949:2016. Inspections cover chemical composition, mechanical properties (tensile strength, hardness), dimensional accuracy, and surface quality. Certifications such as SGS, CE, PPAP are available upon request.
Surface Finishing: Options include galvanizing (blue/zinc/yellow zinc), nickel plating (bright/black), anodizing (for aluminum alloys in related variants), passivation, powder coating, and dacromet. These enhance corrosion resistance, wear resistance, and aesthetic value.
Customization: Fully tailored to drawings or samples—adjusting outer diameter, inner diameter, thickness, hole patterns, and special features (e.g., countersunk angles for CSK washers) to meet unique application needs.
