Small handle

15. Forging and trimming a small handle: A forged part is
made using drop forging technology. Drop forging provides various
ergonomic product shapes. Suitable forging procedures maintain

appropriate "ber orientation, leaving it the same as in rolled blanks.

Super&uous material around a forged part is removed using a special-
purpose trimming tool; material is trimmed to the desired shape,
always making the weight of trimmings as low as possible.
16. Hole broaching and CNC treatment: Broaching shapes the tip
of the jaw. The latter must have optimal thickness for the necessary
functionality of the broach. That is followed by CNC treatment of
small handles that provides the necessary positioning of the broach
assembly.

17. CNC working: CNC working of the small handles provides
accuracy and thus improves the functioning of the entire product.

18. Heat treatment (quenching and tempering) and sanding:
Heat treatment with annealing and tempering is intended to enhance
the structure of steel, product strength and toughness, and other
properties required to withstand the loads to which such a product is
exposed to. Sanding is used to clean the surface for further operations.

19. Sanding: Cleaning the surface before chroming is important for
the sake of quality and durable surface protection.
20. Chroming: The handle of the puller is plated with a thin, hard
coating of chromium oxide, which protects against corrosion and wear
and other mechanical damage. At the same time, it gives the entire
Unior puller a glossy appearance.

Assembly

21. Final assembly: The trained, skilled and meticulous workers

performing the "nal assembly assemble the product into a solid whole
that ensures the functioning and high quality of the Unior puller.
