With the development of the market and the increase in demand, the requirements for products are getting higher and higher. This is nothing more than a good challenge opportunity for the mold accessories manufacturer Dongguan Aokai Precision Mold Co., Ltd. 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 plants should meet for processing high-precision parts?

Precision mold parts

1. Heat and cold fatigue resistance of parts

Some molds are in a state of repeated heating and cooling during the working process, which causes the surface of the cavity to be pulled and pressure to change the stress, causing surface cracks and peeling, increasing friction, hindering plastic deformation, and reducing dimensional accuracy. Mold failure. Hot and cold fatigue is one of the main forms of failure of hot work molds. This kind of Dongguan precision mold parts should have high resistance to cold and heat fatigue.

2. Strength and toughness of parts

The working conditions of precision mold parts are mostly very bad, and some of them are often subjected to greater impact load, which leads to brittle fracture. In order to prevent sudden brittle fracture of mold parts during work, the mold must have high strength and toughness. The toughness of a tool mainly depends on the carbon content, grain size and organization state of the material.

3. High temperature performance of parts

When the working temperature of the mold is higher, the hardness and strength will decrease, leading to early wear of the mold or plastic deformation and failure. Therefore, the mold material should have high anti-tempering stability to ensure that the mold has high hardness and strength at the working temperature.

4. Corrosion resistance of parts

When some molds such as plastic molds are in operation, due to the presence of chlorine and fluorine in the plastics, strong corrosive gases such as HCI and HF will be resolved after being heated, which will erode the surface of the mold cavity, increase its surface roughness, and aggravate wear failure.

5. Fatigue and fracture performance of parts

In the working process of precision mold parts, under the long-term action of cyclic stress, fatigue fractures are often caused. Its forms include low-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 plants should meet when processing high-precision parts. Based on the above points, Aokai Precision Mold believes that only by continuous product innovation, high standards and strict requirements, can it better cater to The future mold parts processing demand market.
