Our Corrosion-Resistant Precision Metal Stamping Parts are engineered to withstand harsh corrosive environments, integrating corrosion-resistant material selection, advanced surface treatment technologies, and rigorous precision control. We specialize in providing customized stamping solutions for industries requiring anti-corrosion performance, covering marine, chemical, food processing, and automotive components, ensuring excellent corrosion resistance, dimensional stability, and long service life to meet the high-performance requirements of global customers.

　　1. Product Overview & Core Technical Parameters

　　Our corrosion-resistant precision metal stamping parts are fabricated from high-performance corrosion-resistant metal materials through specialized processes such as precision blanking, bending, drawing, and coining. Equipped with professional stamping equipment and mold design optimized for corrosion-resistant materials, we overcome the challenges of processing materials with high corrosion resistance (e.g., stainless steel, aluminum alloy) and ensure high-precision manufacturing and efficient mass production. Below are the detailed technical parameters:

　　Material Options: Specialized for corrosion resistance - Austenitic stainless steel (304, 316, 316L, 0Cr18Ni9), ferritic stainless steel (430), aluminum alloy (5052, 6061), brass (C2680), phosphor bronze (C5191), and corrosion-resistant alloy steel; Materials feature excellent corrosion resistance with Cr content ≥17% for stainless steel (forming dense chromium oxide passive film), 316L stainless steel offers superior pitting corrosion resistance in salt spray and chemical environments, and aluminum alloy 5052 provides natural anti-corrosion performance through oxide film formation

　　Precision Specifications: Dimensional tolerance: ±0.01mm ~ ±0.08mm (adapted to corrosion-resistant part assembly requirements); Surface roughness: Ra 0.4 ~ Ra 1.6 (smooth surface reduces corrosion initiation points); Flatness: ≤0.02mm/m; Parallelism: ≤0.03mm; Perpendicularity: ≤0.03mm; Key feature tolerance controlled within ±0.005mm to ensure precise fit with associated components

　　Stamping Processes: Precision blanking, bending, drawing, embossing, coining, progressive stamping, transfer stamping; Adopting CAD simulation to optimize die structure and process parameters, ensuring forming stability of corrosion-resistant materials; Minimizing surface scratches during stamping to avoid damaging the passive film; In-die tapping and welding processes compatible with corrosion-resistant material properties

　　2. Core Advantages: Specialized for Corrosion-Resistant Precision Stamping

　　2.1 High-Performance Corrosion-Resistant Materials & Passive Film Protection

　　We strictly select high-quality corrosion-resistant materials from well-known suppliers, focusing on material composition and passive film formation ability. All raw materials undergo strict incoming inspection, including material composition analysis, corrosion resistance testing (salt spray test, chemical immersion test), and mechanical property testing. For stainless steel materials, we ensure Cr and Ni content meet standard requirements to form a dense and stable chromium oxide passive film on the surface, which effectively blocks the contact between the base metal and corrosive media. Our stamping parts can maintain excellent corrosion resistance in harsh environments such as salt spray, humidity, and chemical erosion, significantly extending the service life of the equipment.

　　2.2 Advanced Surface Treatment Technologies Enhance Corrosion Resistance

　　We adopt a variety of advanced surface treatment technologies tailored for corrosion-resistant requirements, including passivation, electropolishing, and composite coating processes. The passivation treatment accelerates the formation of a dense passive film on the surface of stainless steel parts, improving their resistance to pitting and crevice corrosion. The electropolishing process reduces surface roughness, removes micro-defects, and enhances the uniformity and stability of the passive film. For parts in extremely harsh corrosive environments, we provide composite treatment solutions (e.g., passivation + magnetic polishing) that can extend the salt spray resistance time to over 960 hours, which is more than 10 times that of conventional treatment methods. All surface treatments are strictly controlled to ensure they do not affect the dimensional precision of the parts.

　　2.3 Precision Manufacturing for Corrosion-Resistant Material Characteristics

　　Corrosion-resistant materials such as stainless steel and aluminum alloy have unique mechanical properties (e.g., high ductility, high toughness) that pose challenges to stamping forming. Our professional R&D team uses CAD simulation technology to optimize die structure and process parameters, ensuring uniform material flow and avoiding surface scratches and passive film damage during stamping. We adopt high-rigidity CNC stamping machines and precision molds (mold accuracy: ±0.005mm) to ensure consistent dimensional accuracy of corrosion-resistant stamping parts. The production process is equipped with online surface quality inspection equipment to promptly detect and eliminate defects that may affect corrosion resistance.

　　2.4 Customized Solutions for Diverse Corrosive Environment Needs

　　Our team has rich experience in corrosion-resistant precision stamping, capable of providing customized solutions according to customer drawings, samples, and specific corrosive environment requirements. We specialize in developing stamping parts for various harsh environments, including marine (salt spray corrosion), chemical industry (chemical medium corrosion), food processing (humidity and cleaning agent corrosion), and automotive undercarriage (road salt corrosion). Whether it is marine hardware, chemical equipment components, food machinery parts, or automotive anti-corrosion components, we can tailor the most suitable material selection, stamping process, and surface treatment plan to meet the specific anti-corrosion performance requirements of different industries.

　　2.5 Strict Corrosion Resistance Testing & Reliable After-Sales Service

　　We implement a full-process quality control system tailored for corrosion-resistant precision stamping parts, covering raw material procurement, mold trial, production process, surface treatment, and finished product inspection. All finished parts must pass comprehensive corrosion resistance testing (neutral salt spray test, acetic acid salt spray test, chemical immersion test) and dimensional accuracy testing before leaving the factory, with a qualified rate of up to 99.9%. We also provide a complete after-sales service system, including product corrosion resistance quality tracking, technical support for installation and use in corrosive environments, and replacement of defective parts.
