Lower Electrode And Lower Electrode Holder Combination KCF Guide PIn For Weld Nuts
KCF Guide PIn Lower Electrode And Lower Electrode Holder Combination For Weld Nuts
1 . Descriptions:
Bloom welding is the manufacturer of the KCF bars,and we also make the KCF guide pins.We offer different sizes guide pin,locating pin,bushing,sleeve.Our material include KCF alloy material,ceramic coated,Zirconia ceramic,Silicon nitride ceramic etc.We not only can make the standard size and also can make the KCF pins according to your drawings.Welcome your inquiry.
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.

What is KCF Guide Pins?
KCF material is a special metal material.Through special heat treatment process and process temperature range of 1000-1500 degree adjustment,the surface can generate a layer of 10-32μm thick high-quality insulation layer,the insulation layer and the alloy matrix has a good ability to combine.So that the material takes into account the good wear resistance and high insulation resistance.The material in the mechanical processing after formation of a variety of parts,after cleaning and heat treatment with insulation,wear and anti-oxidation of the three functions of the product.This material is mainly used in resistance welding equipment.
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 |
