IKING cup‑head insulation weld pin, CD stud welding type insulation fastener widely used for HVAC duct, boiler, steam pipeline and storage tank thermal insulation fixing. Copper‑plated steel cup‑head weld pins are made to firmly secure rock wool, mineral wool and fiberglass insulation materials on metal substrates.
As a leading global manufacturer and exporter of insulation attachment systems, China IKING Industrial Group proudly presents the premium IKING cup head insulation weld pin. Specially engineered for high-speed installation, this all-in-one insulation fastener streamlines the attachment of thermal, acoustic, and fireproof lining to sheet metal and ductwork in a single, efficient operation.
By integrating a precision-formed bevel-edged washer with a high-tensile steel weld nail, the IKING cup head insulation weld pin eliminates the need for separate self-locking washers or speed clips, dramatically cutting labor costs and boosting job site productivity.
Seamless CD Capacitor Discharge Welding Performance Designed specifically for CD capacitor discharge welding systems, our pins feature a micro-welding point at the nail base. This allows instantaneous fusion to metal sheets (such as galvanized steel, mild steel, or stainless steel) in milliseconds without causing heat discoloration, burn-through, or cosmetic damage to the opposite side of thin-gauge ductwork.
One-Step Rapid Installation Traditional insulation methods require multi-step processes—welding the pin first, placing the duct liner, and manually securing a speed clip. The IKING cup head insulation weld pin enables "weld-through" application. Operators can press the pin directly through fiberglass blankets, mineral wool, or duct liner to finish fixing and welding simultaneously.
Superior Anti-Tear Cup Head Design The staked-on metal washer features a smooth, beveled outer rim. This cupped design ensures optimal force distribution across the insulation surface, holding light-to-heavy insulation materials firmly in place without tearing the foil facing or crushing the fibers.
Optional Insulated Shank & Kraft Paper Backing For aluminum-foil-faced insulation (ASJ/FSK), IKING offers custom variants with a partially insulated shank (plastic sleeve or paper washer). This prevents electrical arcing between the gun chuck and the aluminum foil facing during CD capacitor discharge welding, ensuring 100% reliable weld contacts every time.
