Dongguan Precision CastingcastingNowadays, it must be adopted in many regions. All kinds of machinery and equipment manufactured by mechanical equipment, cars, etc. are all adoptedDongguan precision casting castings, There are strict specifications for the application of goods. Dongguan Chengmao Hardware Products Co., Ltd. will talk about the following specifications:

How to be competentDongguan precision casting castings?

Dongguan precision casting castingsThe eligibility standard is that the surface of the casting is free of slag, burrs and casting tumors. If there are surface defects on the production and processing surface, the deep layer cannot exceed2 mm. If it is on a non-production processing surface, the depth cannot exceed 1 mm. In addition, in all its positions, there must be no stripe defects and cracks. Considering the said standard,Dongguan precision casting castingsIt can be counted as qualified.

2.Dongguan precision casting castingsIs tempering in the heat treatment process?

Dongguan precision casting castings, In the case of tempering, it is usually in the heat treatment process. Its key purpose is to improve part of the characteristics of castings, and then to improve its performance indicators and actual effects. Therefore, the use of raw materials and the selection of molding processes must be effective.

3. WhycastingCould it be a thin-walled casting?If it appearsWhat are the reasons for bag picking and leaking molten steel?

castingIt can be thin-walled castings because of thecastingIn the process, the mold shell is heated at a high temperature, and during casting, the condensation rate of the metal material is slow, so it can It is a thin-walled casting. for,castingLadle pick-up and leakage of molten steel may be due to poor casting itself, such as insufficient mold shell strength, or poor bonding agent applied, which may cause the aforementioned problems.
