　　Core Technical Advantages: Engineered for Miniature Electronics

　　1. Ultra-Precision Micro-Stamping Technology

　　We adopt high-precision micro-stamping equipment and advanced process control to achieve ultra-small size and high accuracy of parts. Our micro-stamping presses have a precision positioning accuracy of ±0.001mm, capable of processing ultra-thin metal materials (thickness 0.01-0.5mm) and forming miniature parts with minimum feature size of 0.1mm. Key technologies include: ① Micro-dimension control – using high-precision sensors for real-time monitoring of stamping parameters to avoid dimensional deviation; ② Fine blanking technology – ensuring smooth cutting edges of miniature parts with roughness Ra ≤ 0.8μm; ③ Multi-station micro-progressive stamping – integrating multiple processes (blanking, bending, forming, punching) into one, improving production efficiency while ensuring precision consistency. The stamping dimensional tolerance is strictly controlled within ±0.002mm, fully meeting the assembly requirements of miniature electronic devices.

　　2. Specialized Material Selection for Electronic Applications

　　We specialize in processing high-performance materials tailored for miniature electronic devices, including: ① Copper alloys (C1100, C17200 beryllium copper) – excellent electrical conductivity and ductility, suitable for connectors, terminals, and spring contacts; ② Stainless steel (304, 316L) – good corrosion resistance and mechanical strength, ideal for electronic enclosures and structural components; ③ Aluminum alloys (1060, 6061) – lightweight and good thermal conductivity, suitable for heat sinks and lightweight electronic parts; ④ Nickel alloys (Ni201) – high temperature resistance and electrical stability, used in high-reliability electronic components. We strictly control material thickness uniformity and surface quality, ensuring materials meet the processing requirements of micro-stamping and the performance requirements of electronic devices.

　　3. High-Precision Micro-Mold Design & Manufacturing

　　Molds for miniature electronic stamping parts are manufactured using high-precision mold steel (SKD11, DC53) and advanced micro-processing technologies (micro-EDM, 5-axis high-speed milling) with mold precision up to ±0.001mm. Our mold R&D team conducts finite element analysis (FEA) to simulate the micro-stamping process, optimizing mold structure to avoid material wrinkling and cracking during micro-forming. Each mold undergoes rigorous precision calibration and trial stamping, ensuring stable production of miniature parts with consistent precision. For small-batch and customized electronic parts, we provide rapid mold development solutions using additive manufacturing technology, shortening the development cycle by 30%.

　　4. Electronic-Grade Surface Treatment

　　To meet the electrical and environmental requirements of miniature electronic devices, we provide electronic-grade surface treatment services: ① Electroplating (gold, silver, tin, nickel) – enhancing electrical conductivity, corrosion resistance, and solderability, suitable for connectors and terminals; ② Electroless nickel plating – ensuring uniform coating thickness on miniature parts, improving wear resistance; ③ Anodizing – for aluminum parts, providing insulation and corrosion resistance; ④ Passivation – for stainless steel parts, enhancing corrosion resistance without affecting electrical performance. All surface treatment processes comply with RoHS, REACH, and other environmental standards, and the coating thickness is precisely controlled within 0.1-5μm to avoid affecting the assembly of miniature parts.

　　Strict Quality Control System: Precision & Reliability Assurance

　　We implement a full-process quality control system focusing on precision and reliability, covering raw material incoming, micro-stamping, surface treatment, and finished product delivery. Key quality control links include:

　　Raw Material Inspection:Inspect chemical composition, thickness uniformity, surface roughness, and mechanical properties of electronic-grade materials using spectrum analyzers, precision thickness gauges, and universal testing machines. Only materials meeting electronic industry standards are allowed to enter production.

　　Micro-Stamping & Surface Treatment Process Monitoring: Monitor micro-stamping parameters (pressure, stroke, positioning accuracy) in real time using high-precision sensors; track surface treatment processes (coating thickness, adhesion) with non-destructive testing methods. Conduct intermediate inspection of semi-finished products to detect dimensional deviations and surface defects early.

　　Finished Product Precision & Performance Testing: Conduct ultra-precision dimensional inspection using coordinate measuring machines (CMM) and optical microscopes with accuracy up to ±0.0005mm; test electrical conductivity, solderability, and corrosion resistance of finished parts. Implement 100% inspection for critical electronic components, and sampling inspection for general components in accordance with AQL 0.65 standards.

　　Quality Documentation: Provide customers with detailed quality reports, including material certificates, process records, precision test data, and surface treatment reports, ensuring full traceability of product quality and compliance with electronic industry audit requirements.

　　Our quality management system has passed ISO9001:2015 and IATF16949 certifications, and our miniature electronic device metal stamping parts comply with international standards such as IPC, ASTM, and DIN, meeting the strict quality and reliability requirements of global electronic device manufacturers.
