Stud welding machines are critical in non-stick pan production, specialized in joining metal studs (e.g., pan handles, support brackets) to pan bodies (usually aluminum or stainless steel with non-stick coatings like Teflon). Operating via the "arc ignition + pressure bonding" principle, they generate a short, intense arc (10-50ms) to melt stud tips and pan surfaces, then apply pressure to form tight joints—avoiding damage to the delicate non-stick layer.
Key features for non-stick pans: First, precision arc control: The machine limits arc duration to ≤50ms, minimizing heat transfer to the pan body. This prevents non-stick coating degradation (which occurs above 260°C) and keeps the heat-affected zone (HAZ) ≤2mm, preserving coating integrity. Second, adjustable pressure: It applies 50-200N pressure, ensuring firm stud bonding (shear strength ≥150MPa) without warping thin pan bodies (0.8-2mm thick). Third, coating-friendly design: Specialized ceramic nozzles shield the arc, preventing spatter from adhering to the non-stick surface and avoiding post-weld cleaning that risks coating scratches.
In applications, it’s used for two main tasks: 1) Handle stud welding: Joins stainless steel handle studs to pan rims. The machine’s quick arc (30-40ms) ensures the coating near the weld remains intact, meeting food safety standards (e.g., FDA 21 CFR 175.300). 2) Induction coil stud fixing: For induction-compatible pans, it welds small copper studs to pan bottoms, enabling coil attachment—all without damaging the non-stick layer on the inner surface.
Advantages include high efficiency (3-5 welds per minute, fitting 10,000+ pans/day production lines), low defect rates (<0.3%, due to automated parameter control), and compliance with food-grade requirements (no flux or consumables that could contaminate pans). Future upgrades will add vision systems to align studs precisely, further reducing coating risks in high-volume non-stick pan manufacturing.
Stud welding machine for non-stick pan
The non-stick pan special welding nail machine is an automated welding equipment designed for the kitchenware industry, used for precisely welding metal connection parts such as handle fixing nails and rivets on the non-stick pan body. This device adopts microcurrent resistance welding or capacitor discharge technology, ensuring the welding strength while avoiding damage to the non-stick coating of the pot body, thus guaranteeing the aesthetics and durability of the kitchenware.
