Return list Reffer:NITONI Click number:- Release time:2018-04-17

With the development of the market and the increase of demand, the demand for products is getting higher and higher, which is nothing but a good challenge for the mold accessory maker, changsha borun.At present, the variety of mold parts manufacturers and parts more and more, factory production of mold parts can meet the needs of the market is that we need to confront and question.So, what are the standard requirements for the processing of high precision parts in the mold parts factory?

The standard requirements for processing high precision parts of the mould parts factory

1. Cold and thermal fatigue performance of parts.

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. It should have high resistance to cold and heat fatigue.

2. Strong and resilient parts.

The working conditions of precision mould parts are very bad, some of them are often subjected to a large impact load, which leads to brittle fracture.In order to prevent the mold parts from breaking suddenly at work, the mold should have high strength and toughness.The toughness of the material 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 high, the hardness and strength will be reduced, which will cause the die to wear out or to produce plastic deformation.Therefore, the mould material should have high tempering stability to ensure that the mould has higher hardness and strength at working temperature.

4. Corrosion resistance of parts.

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 of parts.

In the working process of precision mold parts, 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 the die depends on its strength, toughness, hardness and inclusions in the material.

Above 5 points is mould factory in the processing of high precision components, shall meet the standards and requirements, based on the above points, changsha borun embellish think, only in product innovation, high standard, strict, can better meet the demand of future mold accessories market.
