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.
We produce and supply all kinds of resistance welding
accessories,welding electrode,electrode tips,cap tips,electrode
holder,electrode arm,adapter,welding wheel,straight shank,bent
shank,KCF guide pins,KCF sleeve,tip dresser tool,welding tester.

We offer various sizes of KCF guide pin and KCF sleeves. The
standard kcf pins are always in stock.Also supply customized pins
according to your drawing.With excellent insulation performance and
long-life,our kcf guide pins are directly or indirectly used on
GM,VW,TOYOTA etc.automotive welding factory.
KCF Guide Pin Technical Specification
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
KCF Guide Pins Advantage:
Good insulation performance
Excellent wear resistance ability
High temperature anti-oxidation performance
Good heat shock performance
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.
KCF Positioning Pin
a)Special ferrochrome alloy
b)Characterized by good hardness and strength and toughness
c)Low-voltage insulation on the surface after special heat treatment
process
d)processing is convenient and the cycle is shorter
KCF guide pins advantages:
1 |
Good insulation performance |
2 | Excellent wear resistance ability |
3 | High temperature anti-oxidation performance |
4 | Good heat shock performance |
| 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. |
