Standard requirements for machining high-precision parts for precision parts Release date:

With the development of the market and the increase in demand, the requirements for products are also getting higher and higher. At present, there are more and more mold parts manufacturers and types of parts. Whether the mold parts produced by manufacturers can meet the needs of the market is a problem that we need to face and consider together. So, what are the standard requirements that precision mold processing factories should meet when processing high-precision parts?

Precision mold parts

1. Heat and cold fatigue resistance of precision parts processing

Some molds are in a state of repeated heating and cooling during the working process, which causes the surface of the cavity to be subjected to tension, pressure and stress, causing surface cracking and peeling, increasing friction, hindering plastic deformation, and reducing dimensional accuracy. , resulting in mold failure.

2. Machining toughness of precision parts

Machining of precision parts

Most of the working conditions of precision mold parts are very harsh, and some often bear large impact loads, resulting in brittle fracture. In order to prevent sudden brittle fracture of mold parts during operation, the mold must have high strength and toughness. The toughness mainly depends on the carbon content, grain size and organizational state of the material.

3. High temperature performance of parts

When the working temperature of the mold is high, the hardness and strength will decrease, resulting in early wear of the mold or plastic deformation and failure. Therefore, the mold material should have high anti-tempering stability, and the precision stamping mold should ensure that the mold has high hardness and strength under the working temperature.

4. Corrosion resistance of parts

When some molds such as plastic molds are working, due to the presence of chlorine, fluorine and other elements in the plastic, strong corrosive gases such as HCI and HF are decomposed after heating, which erodes the surface of the mold cavity, increases its surface roughness, and exacerbates wear failure.

5. Fatigue fracture performance of parts

During the working process of precision mold parts, fatigue fracture is often caused under the long-term action of cyclic stress. Its forms include small-energy multiple impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture and bending fatigue fracture. The fatigue fracture performance of the mold mainly depends on its strength, toughness, hardness, and the content of inclusions in the material.

The above 5 points are the standards and requirements that mold parts processing factories should meet when processing high-precision parts. Based on the above points, only with continuous product innovation, high standards and strict requirements can we better cater to future molds Parts processing demand market.
