A good precision mold parts manufacturers, the production of mold spare parts products, if you want to win the market, by the customer and the recognition of the industry, is not easy to do, there needs a long time of polished and improved process.Therefore, in the final analysis, the product quality is the key, so, as a mold parts manufacturers, changsha BoRun Mould Parts think, manufacturer of precision mold standard parts and features should grasp the following aspects:

What should the manufacturer control precision mould parts standard and characteristics?

1. Thermal fatigue resistance

Some mold in the process of work is in a state of repeated heating and cooling, the cavity surface tension, pressure and stress effect, cause surface cracking and spalling, increase the friction, obstacles to plastic deformation, reduces the dimension precision, resulting in the mould failure.Cold and heat fatigue is one of the main forms of thermal die failure, which should have high resistance to cold and heat fatigue.

2. Strong toughness

Most of the working conditions of precision die fittings are very bad, and some of them often bear a large impact load, which leads to brittle fracture.In order to prevent the sudden break of mold parts at work, the mold should have high strength and toughness.The toughness of the mould depends on the carbon content, grain size and the state of the material.

3. High temperature performance

When the working temperature of the mold is higher, the hardness and strength will decrease, causing the die to wear out or to produce plastic deformation.Therefore, the mould material should have high anti-tempering stability to ensure that the mould has a high hardness and strength under working temperature.

4. Corrosion resistance

Some mould such as plastic die on the job, as a result of the elements such as chlorine, fluorine plastics, thermal decomposition after precipitation HCI, HF, such as strong erosion gas, erosion surface of mould cavity, increasing its surface roughness, aggravate the wear failure.

5. Fatigue fracture performance

In the process of precision mould parts, the fatigue fracture is often caused by the long-term effect of cyclic stress.Its form has small energy multiple impact fatigue fracture, tensile fatigue fracture contact fatigue fracture and bending fatigue fracture.The fatigue fracture performance of molds depends on its strength, toughness, hardness and inclusions in the material.
