Spot Weling KCF Pins For Resistance Welding M4 / M5 / M6 / M8 / M 10
KCF is a special metal materials, the main metal elements include iron, chromium, lead, mercury, PBB, PBDE, etc., with special heat treatment process and temperature range 1000-1500 in the process of adjustment, can be generated an 8-10u thickness high quality insulating layer in the surface , this material can be processed into pin, pipe and all kinds of shapes, it is mainly used for high temperature, insulation environment protection some product parts, like bolt, nut welding in automobile industry.
Normally we have the standard size fo M4/M5/M6/M8/M10 and we also accept the customized types.
You just need to share the drawings you want and we will quote for you.
We generally use ceramic guide pins as a welding nut positioning pin, but because of the toughness of ceramics is poor, fragile, so now KCF guide pin instead of ceramic is more and more popular.
KCF Guide Pins /Sleeve is not an insulation coating but a specially processed insulation material which does not peel.
Pin Material: KCF,AL2O3,ZrO2,Si3N4,Ceramic,Stainless Steel etc.
KCF Pins Diameter:M4,M5,M6,M8,M10,M12...
Application: KCF guide pins are widely used on projection welding,nut welding,stud welding
▲high temperature strength
▲superior thermal shock resistance
▲ excellent wear resistance
▲good fracture toughness
▲mechanical fatigue and creep resistance
▲ Excellent non-wetting property with good oxidation resistance
▲ It is convenient to process the rod shape, and the period will be shorter
