Automative welding location pin made of nanometer zirconia

Wuxi Tecceram Fine Ceramic Co., Ltd, founded in 2013, is focus on high technique and high precision engineering ceramic products. Material include high purity alumina (>99.8%, ivory color), 3mol% yttria stabilized zirconia (3Y-TZP, white color), super high bending strength and toughness nano-meter zirconia (3Y-TZP, blue color), magnesium oxide full stabilized zirconia (Mg-PSZ, yellow) and silicon nitride (grey color or black color ). The raw material of these ceramics are imported from German, Janpan and France.

The ceramic raw material of our welding pin, nanometer zirconia powder, is imported from Germany. After shaping by cold-isosactic-pressing (CIP), debinding and sinter, the rods are re-heat-treated by thermo-isostacic-pressing (HIP). Then the HIPed rods are grinded to welding pin by CNC to keep high dimension precision (with tolerance 0.002mm) and then polished by diamond to get perfect surface.(Roughness Ra<0.03um).     

The mechanical property of the ceramic after HIP is very high with bending strength higher than 1200MPa, fracture toughness 14MPa•m^1/2 and extremely high abrasion resistance. The life time of the our welding pin is much higher than special steel and KCF material.

Our welding pin material is completely ceramic from inside to surface. The electrical insulation of the ceramic can completely avoid faulty welded joint defects of auto-body spot welding, which is the fatal weakness of ceramic coated pins like KCF.

    To avoid ceramic falling off from the metal connection during use, we use a threaded and strong adhesive connection method to ensure that the ceramic will not fall off from the metal even if the product is subjected to significant tensile force.
