What are the requirements for machining precision mold parts

With the development of the market and the increase in demand, the requirements for products are becoming higher and higher. Therefore, as a mold parts manufacturer that deals with the mold industry a lot, if you want to produce high-precision and efficient mold parts, you must meet relevant requirements. So, what requirements should mold accessories meet when processing high-precision parts? The following are the requirements compiled by the editor for you that mold parts factories must meet the following requirements when processing high-precision parts:

Hot and cold fatigue resistance of parts.

Some molds are in a state of repeated heating and cooling during the working process, causing the surface of the cavity to change stress under tension and pressure, causing surface cracking, peeling, increased friction, and hindering plastic deformation. , the dimensional accuracy is reduced, resulting in mold failure. Thermal fatigue is one of the main failure modes of hot working molds, so this type of precision mold parts should have high thermal fatigue resistance.

Parts are strong and tough.

Most of the working conditions of precision mold parts are very harsh, and some often bear large impact loads, leading to brittle fracture. In order to prevent mold parts from suddenly breaking during work, the mould should have high strength and toughness. Its toughness mainly depends on the carbon content, grain size and organizational state of the material.

High-temperature performance of parts

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

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, corrosive gases such as HCI and HF will be decomposed after heating, which will corrode the surface of the mould cavity and increase its surface roughness. degree, aggravating wear and failure.

Fatigue fracture performance of parts

Precision mould parts often lead to fatigue fracture under the long-term action of cyclic stress during the working process. Its forms include low-energy multi-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.
