Choose 20# material filter cover, processing technology has warm forging, The forging process of the product is essential to heat treatment, one of the procedures is annealing, is to heat the steel whose organization deviates from the equilibrium state to the appropriate temperature, heat preservation to a certain time, and then slowly cooling.

The other process is tempering. The purpose of tempering is:
1. Reduce brittleness, eliminate or reduce internal stress, there is a lot of internal stress and brittleness of steel after quenching, such as not tempering in time often make steel deformation and even cracking.

2. Obtain the mechanical properties required by the workpiece, the workpiece after quenching high hardness and brittleness, in order to meet the requirements of different performance of various workpiece, can be adjusted by appropriate tempering with hardness, reduce brittleness, get the required toughness, plasticity.

3. Stabilize the workpiece size.

4. For some alloy steel that is difficult to soften by annealing, high temperature tempering is often used after quenching (or normalizing), so that the carbide in the steel is properly aggregated, and the hardness is reduced to facilitate cutting.

Innovation is the essence, integrity is fundamental, responsibility is the principle, pursuit is the spirit. "Innovation" is the essence of Weiying. We take the concept innovation as the forerunner, the strategic innovation as the direction, the technology innovation as the power, the management innovation as the means, the market innovation as the goal, the innovation runs through every detail of the enterprise development. It is the core value system gradually formed in our years of development, with us from small to large, from weak to strong, firm through more than a decade. The "innovation" culture itself also innovates and develops continuously in every stage of the enterprise. In this regard, our employees generally agree, take the initiative to participate in, and actively promote!

Honesty, honesty, honesty, honesty and strong enterprises, integrity is the foundation of enterprises to become stronger.

Responsibility is a kind of power that not only promotes the growth and expansion of an enterprise, but also promotes the progress and development of a nation.

Pursuit, is a positive positioning of the value of thought, but also a self-climbing and transcendence, human progress from the eternal pursuit.
