Stamping Parts are core components in power fittings and optical cable accessories. Formed by applying pressure to sheet metal using precision molds, they are widely used in key components such as ADSS/OPGW cable fittings, connectors, and suspension clamps. Handan Jinmai Fastener Manufacturing Co., Ltd. specializes in the custom production of stampings. Leveraging advanced forging and CNC technology, we provide high-precision, high-strength metal parts for the power, communications, and railway industries, supporting processing based on supplied drawings and samples.
1. High precision and consistency: CNC punching and mold-based production ensures consistent mass production, ensuring compatibility with demanding power system installation environments.
2. Superior strength and durability: Made from high-quality carbon steel/stainless steel, heat-treated and strengthened, the components boast a tensile strength exceeding 500 MPa and excellent fatigue resistance, making them suitable for high-voltage transmission applications.
3. Lightweight design reduces redundant material through structural optimization, resulting in a 30% weight reduction compared to traditional castings, reducing tower loads and improving installation efficiency.
4. Corrosion resistance: The surface is galvanized/Dacromet-treated and salt spray tested for over 1000 hours, meeting long-term outdoor corrosion resistance requirements.
1. Precision stamping and forming utilizes a 630-ton friction press and CNC punch press to complete blanking, punching, and bending processes, supporting sheet metal thicknesses from 0.5 to 20 mm.
2. A quenching and tempering process increases hardness (HRC 28-35), while shot blasting enhances surface adhesion.
3. Full-process quality inspection: Each batch undergoes three-dimensional coordinate measurement and tension testing, complying with DL/T 768 and other electrical hardware standards to ensure a gripping force ≥ 95% of the ultimate tensile strength of the optical cable.
