Cutting material is the first operation in the technological procedure to manufacture a ratchet casing. Optimum design of a cut provides optimal use of material.

The forging technology at Unior ensures excellent strength properties of wrenches. Notably, it maintains an appropriate course of fibres in a forged part, leaving them uninterrupted and the same as in a rolled blank. That characteristic is vital for achieving the characteristics of products typically exposed to heavy and dynamic loads, such as a ratchet.

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.

A CNC machine is used to make a ratchet casing within the necessary tolerance margins for optimal functioning of the final product.

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.

A ratchet housing is plated with a thin, but hard coating of chromium oxide that protects against corrosion and wear and other external influence. At the same time, it gives the entire product a brilliant and professional appearance.

Machining is carried out on a CNC machine, which ensures the necessary accuracy. The pinion is one of the essential elements of a ratchet and individual sizes have to be executed within very narrow tolerance margins.

Teeth on a pinion are shaped with a broaching operation. The obtained 72-teeth geometry guarantees the necessary two-sided shifting of an Unior ratchet.

Ratchet parts 12-16 are made using advanced manufacturing procedures, such as sintering and injection moulding. Quality materials provide optimum strength and premium durability.

Well qualified, skilled and meticulous employees performing the final ratchet assembly will assemble the product into a whole ensuring a top-quality final product. An Unior ratchet will withstand up to 30% higher loads than standard requirements.
