  17. 17. • Sino Stone uses 3 die 3 blow cold forging machine to produce shear connector with chamfer which depends on the mold of cold forging machine. • It can’t produce the shear stud with chamfer when using one die two blow cold forging machine, which is popular with most factory in Handan City of Hebei Province. Chamfer or not? Note: You seldom find the shear connector with chamfer in the factory of Handan City in Hebei province, this is one season for their low price.
  18. 18. • There are two ways to clean oil after the shear stud by cold forging. Sino Stone uses new cleaning oil machine(left photo), most factories in Handan use the rotating cylinder which is full of shear stud and wooden piece together. Cleaning Oil Process
  19. 19. • Most factories in China install aluminum ball by hand. However, Sino Stone uses automatic riveting machine to install it. Installing aluminum ball process
  20. 20. • Thear are two types packaging for shear connector: – Barrel&Pallet: About 200kgs/barrel, 6barrels/pallet – Carton&Pallet: About 25kgs/carton, 36cartons/pallet Package of Shear Connector
  21. 21. • UF ceramic ferrule is designed for unthreaded stud and shear connector, there are two types of UF type, one is for normal welding with 20 teeth, another is for through deck(it is also called thru-deck) welding with 8 teeth. Ceramic Ferrule
