Product Introduction:
If you are producing pipe clamps, luggage buckle clamps, or automotive exhaust hoop clamps, this custom dual-head capacitor discharge projection welding machine will be your best production partner. This equipment is deeply focused on the connection scenarios of ring-shaped metal parts and specially shaped stamped parts, adopting a semi-automatic mode of “left and right dual vibratory bowl feeding of small parts + manual loading of large parts.” After the operator places the carbon steel ring into the center fixture, the two independent welding cylinders on the left and right press down in sequence, and the capacitor power supply instantly welds the buckle firmly. This design of completing stepwise projection welding at both ends in a single clamping completely eliminates displacement of ring-shaped workpieces under force, making it particularly suitable for segmented industries such as hardware fasteners, appliance hoop clamps, and automotive parts that require high-volume, high-consistency welding.
Features:
1.Designed specifically for ring-shaped parts: Developed entirely around the structural characteristics of “circular buckle clamps,” it solves the difficulties of positioning ring-shaped workpieces on traditional welding machines and their tendency to slide under force.
2.Solves the feeding pain point of small buckle parts: In response to the small size of buckle clamp parts and the slow speed of manual picking, custom-developed dual vibratory bowl tracks ensure that small parts do not jam or flip over and are delivered precisely.
3.Perfectly adapts to different sizes: The fixtures and vibratory bowl tracks offer a certain degree of adjustability. By simply replacing the tooling, production can be quickly switched to carbon steel rings and clamps of different diameters.
4.Broad coverage of hardware and auto parts: The equipment has been successfully applied in segmented scenarios such as exhaust pipe clamps, pipe hoops, and luggage buckles. It is highly specialized and an essential tool for building hit products in vertical niche industries.
5.In-depth customization service: Comprehensive non-standard customization is available, from equipment appearance and fixtures to PLC control programs, ensuring the equipment integrates perfectly into your existing production line.

Welding Workpiece: Engineered specifically for tabbed steel clamp rings and broad ring-shaped hardware like pipe hoops, exhaust clamps, and U-clamps, this dual-head step-by-step capacitor discharge projection welding machine handles carbon steel, galvanized steel, and stainless steel components. It perfectly resolves the thermal deformation and spatter issues of thin-walled ring welding, making it an ideal equipment for mass production in hardware fasteners, automotive parts, home appliances, and pipeline engineering.
