Production Process
Supports have two parts:left and right
A pairs were used on disk harrow , they are used to support the spring seat and the spring,disk harrow is common agricultural machinery.
The production process of Supports includes hot die forging, quenching+tempering and CNC.
Supports need to bear a strong pressure , so their material is chosen to be DIN42CrMo4,and through the hot die forging and QT , In order to improve their mechanical properties and hardness of the products, and thus enhance their stiffness and wear resistance.
Because the product needs interference fit, enough smooth surface roughness, high precision of size and shape tolerance, we use CNC and custom tooling for product accuracy.
This is all the result of our joint development with our customers

Inspection
In the production process, we strictly control the quality of each link of the product: material, hardness after heat treatment, and at the same time, according to the requirements of customers, we also made special inspection tools to test the accuracy of the products, so as to ensure that customers can assemble the products smoothly.
