HEAT TREATMENT
The heat treatment step in the nipper manufacturing process plays an important role in improving the mechanical properties of the material.
Early stage
Heating the raw material to high temperature to soften and homogenize the grain structure of the metal.
Later stage
The material is held at this temperature for a certain period of time before undergoing a rapid water quenching process, which creates a harder structure.
Final stage
The final stage is relaxation, in which the product is reheated at a lower temperature to relieve stress and improve ductility.
In this way, heat treatment not only increases the hardness and fatigue strength of the pliers, but also reduces brittleness, giving the product strength and extending its service life.
Testing and evaluating the properties after heat treatment is necessary to ensure that the product meets technical standards, thereby improving the quality and performance of the pliers.
