Excellent Wear Resistance Ability,Cost - Effective KCF Guide Sleeve , For Nut Welding
1 . Descriptions:
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 cheaper in the business.
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.
