Tailored for the high-precision positioning needs of M10-sized workpieces in welding lines with automatic feeding systems (such as nut conveyors superscript:5), our positioning pin adopts a one-piece KCF material structure, with a precision-machined pointed tip (standard pointed angle 60°, compatible with M10 nut inner hole size of 11mm superscript:3) and a matching M10 thread design that perfectly fits mainstream welding jigs, fixtures, positioning bases and automatic feeding workstations superscript:3 superscript:5. KCF, a special chromium-iron alloy material originally developed by Toshiba Corporation superscript:3 superscript:4, forms a high-quality insulating layer (8-10μ thick) on its surface through special heat treatment (1000-1500℃) superscript:3 superscript:4, enabling it to effectively isolate welding current while maintaining excellent mechanical strength. This unique material advantage makes it an ideal alternative to traditional ceramic locating pins, solving the problem of ceramic pins being brittle and easy to break superscript:3 superscript:4. The pointed design ensures fast, accurate and smooth guiding and positioning of workpieces (especially nuts) during automatic feeding, preventing jamming or misalignment in the feeding channel, while the precise thread and positioning accuracy ensure that workpieces are fixed in the correct position during welding, avoiding deviation, tilting or displacement. It is widely compatible with various resistance welding equipment such as robotic spot welders, projection welders and fixed spot welders, and is widely used in automotive manufacturing, hardware processing, sheet metal fabrication and precision machinery industries, especially suitable for large-batch, high-standard welding lines with automatic feeding that require strict positioning accuracy and high efficiency.
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 Pointed Positioning Pin — a special metal material that combines the advantages of metal toughness and ceramic insulation superscript:3 superscript:4. 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:4. 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 positioning 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 in automatic feeding welding lines.
Our M10 KCF Pointed Positioning 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 positioning pin (thread specification, pointed tip 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 automatic feeding workstations superscript:5. The pointed tip is precision ground to a sharp, burr-free finish (Ra≤0.8μm), ensuring fast, smooth guiding of workpieces during automatic feeding and accurate positioning without jamming or damage to workpiece holes, threads or surfaces. The high-temperature heat treatment process enhances the material's hardness (HRC 45-50) and wear resistance, making the positioning 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:1), with precise tooth pitch and smooth surface, ensuring firm installation and no loosening during high-speed automatic feeding and welding vibration. 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 automatic feeding workstations (such as nut conveyors that adapt to M10 nuts superscript:5) at home and abroad, and perfectly matching the standard hole diameter of 11mm for M10 nuts superscript:3.
Core Product Advantages
1. Premium KCF Material, Superior Performance
Made of high-quality KCF chromium-iron alloy, the M10 KCF Pointed Positioning Pin combines the advantages of metal toughness and ceramic insulation. The special heat treatment process forms a dense 8-10μ thick insulating layer on the surface superscript:3 superscript:4, which can effectively isolate welding current, prevent arc leakage and short circuit, and avoid damage to workpieces or equipment caused by current conduction. Compared with traditional ceramic locating pins, KCF material has better toughness and impact resistance, effectively solving the problem of ceramic pins being brittle and easy to break, greatly extending the service life of the positioning pin superscript:3 superscript:4. It also has excellent high-temperature resistance, maintaining stable performance and structural integrity in continuous high-temperature environments (up to 400℃) and resisting instantaneous high temperatures up to 600℃, which is far superior to ordinary steel positioning pins. The material's excellent wear resistance ensures that the pointed tip does not easily wear or deform even under frequent high-speed positioning operations, maintaining precise positioning accuracy for a long time, which is crucial for stable operation of automatic feeding welding lines.
2. Precision M10 Design, Accurate Positioning & Automatic Feeding Compatibility
The positioning pin is specially designed for M10 specifications, with a precision-machined thread (M10×1.5 coarse thread and M10×1.0 fine thread superscript:1) and pointed tip structure that perfectly fits M10-sized workpieces, welding fixtures and automatic feeding workstations (such as nut conveyors superscript:5). The strict tolerance control (±0.003~±0.005mm) ensures ultra-high positioning accuracy, effectively avoiding workpiece misalignment, tilting or displacement during welding, and ensuring consistent welding quality. The pointed design is specially optimized for automatic feeding scenarios, featuring a sharp, smooth tip that allows for fast, unobstructed guiding of workpieces (especially nuts) through automatic feeding channels, preventing jamming or misalignment — a key advantage over round head positioning pins which are more suitable for manual feeding systems superscript:7. The precise thread design ensures firm installation with welding jigs, no loosening during high-frequency welding vibration and high-speed feeding, and stable positioning performance, fully adapting to large-batch, high-standard welding lines with automatic feeding. It also matches the standard M10 thread drilling diameter (8.5~8.7mm for M10×1.5, 9.0~9.2mm for M10×1.0) and the standard hole diameter of 11mm for M10 nuts superscript:3, ensuring seamless assembly with existing fixtures and automatic feeding equipment.
3. Pointed Tip Design, Ideal for Automatic Feeding Operations
The integral pointed tip structure is a key design feature of our M10 KCF positioning pin, specifically developed for automatic workpiece feeding superscript:3 superscript:7. Unlike round head positioning pins which are designed for manual feeding systems, the sharp, precision-ground pointed tip allows for fast, smooth guiding of nuts or workpieces into the positioning hole through automatic feeding channels (such as nut conveyors superscript:5), reducing feeding resistance and avoiding jamming, misalignment or damage to workpiece surfaces, threads or holes — a common pain point in automatic feeding welding lines. The pointed tip also ensures precise alignment with workpiece holes, especially for M10 nuts, ensuring that the nut is correctly positioned before welding, even in high-speed feeding scenarios. The smooth surface of the pointed tip reduces friction between the pin and workpiece, minimizing wear and extending the service life of both the positioning pin and the workpieces. For large-batch, automatic feeding production, this design significantly improves positioning efficiency and workpiece quality, reducing rework caused by feeding jamming or misalignment.
4. Strong Customization Capability for Diversified Needs
We support full non-standard customization according to customer-provided drawings, samples and actual welding working conditions. Whether it is the size specifications (overall length 15~100mm, pointed tip angle 45°~90°, thread specification M10×1.5/M10×1.0 or non-standard threads), material optimization (enhanced wear-resistant KCF, customized insulation layer thickness), or special structural design (extended thread, stepped pointed tip, anti-slip thread), our professional R&D and machining team can provide targeted solutions. We can also customize the positioning pin according to the specific model of welding equipment (robotic spot welder, projection welder) and automatic feeding workstation (such as nut conveyors superscript:5), workpiece material (high-strength steel, aluminum alloy, galvanized plate) and working environment (high temperature, high humidity, heavy spatter), meeting the diversified and personalized positioning needs of different industries. For special positioning scenarios, we can also adjust the pointed tip size and sharpness to ensure perfect fit with workpieces and feeding channels, and optimize the insulation layer thickness according to specific current isolation requirements.
