Premium KCF Material & Advanced Manufacturing Process
Adhering to the production principle of "Materials as the foundation, technology as the core, and quality as the life", we select high-quality KCF material (chromium-iron alloy) for our M10 KCF Round Head Locating Pin — a special metal material that combines the advantages of metal toughness and ceramic insulation superscript:3 superscript:6. Different from ordinary steel or ceramic materials, KCF is processed through special heat treatment at 1000-1500℃, forming a dense insulating layer on the surface, which can effectively isolate welding current and prevent arc leakage, while its metal matrix ensures excellent toughness and impact resistance, avoiding brittle fracture common in ceramic locating pins superscript:3 superscript:6. All KCF raw materials undergo strict incoming inspection, including material composition testing, insulation performance verification, high-temperature resistance detection and mechanical strength test, to ensure stable performance (insulation resistance >1.0×10¹²Ω, continuous use temperature up to 400℃, instantaneous high-temperature resistance up to 600℃), laying a solid foundation for the locating pin's long-term stable operation in harsh welding environments. Compared with imported KCF materials, our domestically produced KCF material maintains the same performance while offering higher cost-effectiveness, making it a cost-efficient choice for high-precision positioning needs.
Our M10 KCF Round Head Locating Pin adopts an integrated manufacturing process of precision CNC turning, high-temperature heat treatment, precision grinding and surface polishing. We adopt advanced CNC machining technology to ensure that all dimensions of the locating pin (thread specification, round head size, overall length, positioning accuracy) meet international standards (GB, DIN, ISO, ANSI), with strict tolerance control (±0.003~±0.005mm) to ensure precise matching with M10-sized workpieces, welding fixtures and manual feeding workstations superscript:4. The round head is precision ground to a smooth, burr-free finish (Ra≤0.8μm), ensuring damage-free guiding of workpieces during manual placement and accurate positioning without scratching workpiece holes or threads. The high-temperature heat treatment process enhances the material's hardness (HRC 45-50) and wear resistance, making the locating pin not easy to wear, deform or corrode under long-term high-frequency positioning and high-temperature welding conditions. The thread part is processed according to standard M10 specifications (M10×1.5 coarse thread and M10×1.0 fine thread superscript:2), with precise tooth pitch and smooth surface, ensuring firm installation and no loosening during operation. Every finished product undergoes comprehensive quality inspection, including dimensional accuracy testing, insulation performance detection, wear resistance verification and surface defect inspection, to ensure zero defects before delivery. Standard models are available in common lengths (18~45mm) and can be customized according to customer needs, compatible with mainstream welding jigs, fixtures and manual feeding workstations at home and abroad, and perfectly matching the standard hole diameter of 11mm for M10 nuts.
Core Product Advantages
