KCF Insulation Guide Sleeve Tube Bushing For Resistance Welding
1 . Descriptions:
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.
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.
| Ceramic (solid) | Traditionally Silicon Nitride -fully insulated. | Grey, White, Beige, Blue | High intial cost but will last longer than any other pin when conditions allow. Sosceptible to damage. Repels weld spatter. |
| KCF | A special heal treated alloy with a hard,insulating skin | Grey / Black | A low cost pin with a reasonable lifespan |
KCF Guide Pins /Sleeve is not an insulation coating but a specially processed insulation material which does not peel.
Has been being used in resistance welding applications for several decades. It has an insulated skin on its surface. Any shape can be made quickly. Our standard shapes are the cheapest in the business.
2 . KCF Guide Pin Technical Specification
Pin Material: KCF,AL2O3,ZrO2,Si3N4,Ceramic,Stainless Steel etc.
Application: KCF Sleeves are widely used on projection welding,nut welding,stud welding
3 . Advantages:
▲high temperature strength
▲ superior thermal shock resistance
▲ perfect 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
