　　Surface-Coated Wear-Resistant Metal Stamping Parts: High-Durability Solutions for Industrial Applications

　　In industrial environments where metal stamping parts are subject to frequent friction, impact, and harsh working conditions, wear resistance is a critical performance requirement. Our Surface-Coated Wear-Resistant Metal Stamping Parts integrate precision stamping technology with advanced surface coating processes, delivering exceptional wear resistance, corrosion resistance, and service life. Backed by a professional R&D team and rich manufacturing experience, we provide one-stop customized solutions, covering product design, mold development, precision stamping, professional surface coating, and strict quality inspection. Our products meet international industrial standards, successfully serving customers in automotive, machinery, aerospace, and other high-demand industries across over 30 countries and regions worldwide.

　　Core Technical Advantages: Advanced Coating Technology & Precision Manufacturing

　　1. High-Performance Surface Coating Technologies

　　We adopt a range of advanced surface coating technologies tailored to different wear resistance requirements, ensuring optimal performance for specific applications: ① Thermal Spray Coating (e.g., HVOF high-velocity oxygen fuel spraying of WC-Co, Cr3C2 coatings) – the coating hardness reaches HRC 65-70, with excellent wear resistance and impact resistance, suitable for heavy-duty friction parts; ② Physical Vapor Deposition (PVD) – including TiN, TiAlN, CrN coatings, featuring high hardness, low friction coefficient (≤0.2), and good adhesion, ideal for precision parts in automotive and electronic industries; ③ Hard Chrome Plating – provides a smooth, dense coating with hardness up to HRC 60, excellent wear and corrosion resistance, widely used in hydraulic components and mechanical parts; ④ Ceramic Coating – offers superior high-temperature resistance (up to 1200℃) and chemical stability, suitable for high-temperature working environments. All coating processes are equipped with precise thickness control systems, ensuring coating thickness uniformity (tolerance ±0.005mm).

　　2. Precision Stamping & Coating Compatibility Design

　　We combine high-precision stamping technology (stamping speed up to 1200 times/min, dimensional tolerance ±0.01mm) with coating compatibility design to ensure the stamping parts maintain structural integrity and performance after coating. Before stamping, we optimize the material selection and process parameters based on the intended coating type – for example, selecting low-carbon steel or alloy steel with good surface properties for thermal spray coating, and pre-treating the material surface to enhance coating adhesion. For complex-shaped parts, we adopt multi-station progressive stamping to avoid surface defects that may affect coating quality, ensuring the final products have both high dimensional accuracy and excellent wear resistance.

　　3. Professional Pre-Coating & Post-Coating Treatment

　　To ensure coating adhesion and performance, we implement strict pre-coating and post-coating treatment processes. Pre-coating treatment includes degreasing (alkaline cleaning + ultrasonic cleaning), derusting, sandblasting (surface roughness Ra 0.8-1.2μm), and activation, which effectively removes surface impurities and creates a rough surface for strong coating bonding. Post-coating treatment includes grinding, polishing, and passivation – grinding ensures coating surface flatness and dimensional accuracy, while passivation enhances corrosion resistance. Our professional treatment processes ensure the coating adhesion strength reaches ≥50MPa, preventing coating peeling or cracking during use. The service life of our surface-coated wear-resistant stamping parts is 3-5 times that of uncoated parts.

　　4. Diversified Material & Coating Matching Capabilities

　　We have rich experience in matching various metal materials with suitable coating technologies, including carbon steel (Q235, 45#), stainless steel (304, 316L), aluminum alloy (6061, 5052), copper alloy (H62, H65), and special alloys (titanium alloy, spring steel). According to the working conditions of the parts (e.g., friction intensity, temperature, chemical environment), we customize the optimal material-coating combination. For example, for high-temperature friction parts, we match Inconel alloy with ceramic coating; for precision electronic parts, we match stainless steel with PVD TiN coating. All coating materials comply with international environmental standards (RoHS, REACH), ensuring environmentally friendly and non-toxic products.

　　Strict Quality Control System: Wear Resistance & Quality Assurance

　　We implement a full-process quality control system focusing on wear resistance performance, covering raw material inspection, stamping process inspection, coating process monitoring, and finished product performance testing. Key quality control links include:

　　Raw Material & Coating Material Inspection: Inspect the chemical composition, mechanical properties of metal materials with spectrum analyzers and tensile testing machines; test coating materials for purity, particle size, and adhesion to ensure quality.

　　Stamping & Coating Process Monitoring: Monitor stamping parameters (force, stroke, temperature) in real time to avoid surface defects; track coating process parameters (temperature, pressure, time) to ensure coating uniformity and thickness accuracy.

　　Finished Product Performance Testing: Conduct professional wear resistance tests (e.g., pin-on-disk test, abrasion test) to verify wear resistance; test coating hardness with Vickers hardness testers; perform adhesion tests (pull-off test, scratch test) and corrosion resistance tests (neutral salt spray test for 96-200 hours). Conduct 100% dimensional and appearance inspection to ensure product qualification.

　　Quality Documentation: Provide customers with detailed quality inspection reports (including raw material certificates, dimensional test data, and surface treatment test reports) to ensure traceability of product quality.

　　Our products have passed international certifications such as ISO9001:2015, IATF16949 (automotive industry), and CE, complying with strict quality and wear resistance standards in global markets such as Europe, America, and Japan.
