Tin snips

Cutting material is the first operation in the technological procedure of wrench manufacturing. Optimum design of a cut provides optimal use of material.

Forging technology at Unior ensures excellent strength characteristics of wrenches. Notably, it maintains appropriate fiber orientation in a forged part, leaving it uninterrupted and the same as in a rolled blank. That characteristic of forged parts is vital for achieving the characteristics of products exposed to heavy and dynamic loads.

Superfluous 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.

by drilling/sinking, it is possible to achieve the required precision of positioning for each individual jaw.

the heat treatment with hardening and tempering is intended to improve the structure of the steel, to provide greater hardness and toughness of the product and other properties required to overcome the strain that work with such products requires.

local heating and tempering of the jaw serration ensures a high degree of hardness of the functional part of the snips. By hardening, we can achieve the optimum microstructure and the required hardness, which ensure a long service life for the snips.

grinding is done using a special CNC machine, which is used to achieve the correct, optimum angles of the blades and thus the optimum cutting of the Unior snips.

A tin cut, which serves as a base, is made from quality tin that ensures the appropriate hardness and rigidity of the handle even under the highest strain.

the desired shape of the handle is achieved by bending the handle using a special machine with a bending tool that ensures the appropriate link between the jaws and the handles.

the nickel plating surface protection gives the product a professional appearance and provides resistance to corrosion.

the handles are bound together with a suitable, smooth flexible link by way of riveting.

the left and right jaws are bound together into a suitable, smooth flexible link with a screw.

both jaws are linked to the handles with a firm link that gives the Unior snips the required function, which is reliable under even the greatest loads.

the trained, skilled and meticulous workers performing the final assembly put together the individual parts, examine the main characteristics and turn the Unior snips into a high quality product.
