PB-6.2-25 / PB-8.2-25 KCF Sleeve For Wedling Electrode

1. Description

We supply various shapes of KCF sleeve & KCF guide sleeve.Standard size M4,M5,M6,M8,M10,M12 KCF sleeves are always in stock.If you need special sleeve,we accept customization according to your drawing or specification.Our kcf sleeve has high temperature characteristics and good insulation skin to ensure long life.Our KCF sleeves are always used with bolt welding electrode,nut welding electrode,stud electrode and projection welding electrode.

KCF is a special metal materials, its 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.

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.
