With the development of the market and the increasing demand, the requirements for products are getting higher and higher. Whether the mold parts processed by precision parts processing 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 for precision mold processing factories to process high-precision parts?
1. Parts resistant to cold and heat fatigue
Some molds are in a state of repeated heating and cooling during the working process, causing the surface of the cavity to be subjected to tensile and pressure-induced stresses, causing surface cracking and spalling, increasing friction, impeding plastic deformation, and reducing dimensional accuracy, thereby resulting in The mold failed. Hot and cold fatigue is one of the main forms of hot work die failure and should have high resistance to cold and heat fatigue.
2. Parts strength and toughness
The working conditions of precision mold parts are mostly very bad, and some often withstand large impact loads, resulting in brittle fracture. In order to prevent the mold parts from suddenly breaking during work, the mold must have high strength and toughness. The toughness of the material depends mainly on the carbon content, grain size and microstructure of the material.
3, high temperature performance of components
When the working temperature of the mold is higher, the hardness and strength are lowered, resulting in 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
Some molds, such as plastic molds, when working, due to the presence of chlorine, fluorine and other elements in the plastic, after the heat, the HCI, HF and other strong aggressive gases are resolved, eroding the surface of the mold cavity, increasing its surface roughness and aggravating wear and tear.
5, fatigue fracture properties of parts
During the working process of precision mold parts, under the long-term effect of cyclic stress, fatigue fracture is often caused. The form has small energy multiple impact fatigue fracture, tensile fatigue fracture contact fatigue fracture and bending fatigue fracture. The fatigue fracture properties of a mold depend mainly on its strength, toughness, hardness, and the amount of inclusions in the material.
The above five points are the standards and requirements that the mold parts processing factory should meet when processing high-precision parts. Based on the above points, Taijin Precision Mould believes that only when the products are constantly innovating, high standards and strict requirements can they better cater to The future demand for mold parts processing market.
