Copper‑plated CD stud welding insulation pins are pre‑assembled with self‑adhesive paper disc base. It can be temporarily fixed by adhesive before CD‑stud welding. Mainly used for HVAC ducts and ship insulation to fasten rock wool and glass wool. Features easy positioning, stable welding joint, high efficiency for thermal‑insulation fastening projects
IKING CD weld insulation pins are high‑performance capacitor‑discharge welding fasteners specially made for thermal and acoustic insulation fixing. Manufactured by China Aike Industrial Co., Ltd, these copper‑plated weld pins deliver reliable welding performance without drilling or damaging base metal sheets. Made of low‑carbon steel with uniform copper‑plated surface, they offer excellent electrical conductivity during CD stud welding, producing solid, consistent weld spots and avoiding cold‑weld failures.
The cup‑head profile works perfectly with self‑locking insulation washers to hold rock wool, glass wool and insulation boards firmly in place. Even under continuous vibration, temperature swings and outdoor exposure, the insulation layers will not sag or fall off. Every piece is precision‑produced, burr‑free and batch‑inspected, making it a dependable fastening solution for insulation contractors, equipment manufacturers and global distributors.


IKING CD weld insulation pins are widely used for thermal insulation, sound‑absorbing and fire‑proof insulation fastening across multiple industries.
They are heavily deployed on HVAC ventilation duct insulation to secure inner and outer insulation materials and cut heat loss and operational noise. In marine and shipbuilding projects, the copper‑plated surface resists humid and salt‑laden cabin environments to maintain long‑term insulation performance. Besides, these weld pins fit container wall insulation, industrial furnace linings, railway vehicle interior insulation, generator‑set noise reduction and steel‑structure building wall & roof insulation.
Workers weld pins onto steel substrates with CD welding guns, fit insulation materials over studs and lock by self‑locking washers. The whole installation process is fast and labor‑saving, lowering overall construction costs for large‑scale projects.

Our Company is a specialized manufacturer and exporter under the IKING brand, focusing on stud welding fasteners and insulation fixing accessories. We combine in‑house R&D, mass production and strict quality control.
We test dimensions and welding performance for every batch before shipment. Apart from standard CD weld insulation pins, we support custom sizes and special‑request packaging. With competitive factory pricing and responsive technical support, our products are exported to Europe, Southeast Asia, the Middle East and other regions, building stable partnerships with overseas engineering clients and distributors.
Q1: What welding machine works with these CD weld insulation pins? A: They match standard capacitor discharge (CD) stud welding machines. Adjust welding parameters based on pin diameter and base‑plate thickness for best results.
Q2: What is the advantage of copper‑plated treatment? A: Copper‑plated improves electric conductivity for more stable welding joints, meanwhile boosting anti‑oxidation performance in harsh working conditions.
Q3: Can you supply custom sizes and test samples? A: Yes, non‑standard dimensions are supported. Small‑quantity samples can be offered for welding and quality evaluation.
Q4: What is your production lead‑time? A: Standard goods take 3‑7 working days. Custom or large‑volume orders take 7‑15 working days. Urgent projects can get priority arrangement.
Q5: Are the products suitable for heavy‑duty engineering projects? A: All IKING insulation weld pins pass strict outgoing inspection and meet international industrial standards for large‑project applications.
