Manufacturing process of manual punching pliers
The production process of tools includes raw material procurement, parts production, parts surface treatment, and post-assembly. Except for surface treatment, our factory produces other processes by itself.
Selection of raw materials
We analyzed that the steel used by many manufacturers is unqualified, resulting in insufficient tool hardness.
The main body of the manual punching pliers is high-strength carbon steel, which has high hardness and is not easily deformed, so it is very suitable for the manufacture of manual punching pliers. At the same time, the handle of the pliers also needs to choose high-quality materials to ensure the reliability and service life of the product.
Stamping the handle of the pliers
Stamping is one of the key processes of manual punching pliers. The handle of the pliers needs to be formed by stamping. In the stamping process, it is necessary to design the mold first, and carry out typesetting and processing in strict accordance with the design requirements. The material is then placed into a mold, and through pressure and the action of the mold, the material is transformed into the desired shape.
We use continuous mould, which can control the precision of size best
Surface chrome treatment
Surface treatment is one of the quality guarantees of the pliers, and chrome-plated treatment can improve the corrosion resistance and aesthetics of the pliers. The specific steps of the surface chrome plating treatment are cleaning treatment first, then electroplating treatment on the surface of the pliers, and finally polishing and other treatment processes.
There is also a dipping process, or a blackening process. Can make the product anti-rust and beautiful.
Heat treatment of the punch
Heat treatment is one of the important links.
Heat treatment makes the punch harder and more durable, using the correct temperature for quenching and tempering is the exclusive secret recipe of each factory.
Detection
The assembled manual tools need to be inspected to ensure the quality of the tools. The inspection process usually includes appearance inspection, material hardness inspection, hole diameter and spacing correction, service life inspection, etc. Through the testing , it can ensure that the product meets the quality requirements, and at the same time, it can also exclude unqualified products Appear.
Through the production process and testing links of the above content, it can ensure that the product quality of the manual hand tools meets the requirements, has good reliability and service life, and helps users complete efficient operations.
