Q:Casting parts have poor surface finish. What sand is used to make them?
V casting, EPC, precision casting of the surface is good.
Q:What is the reason for 304 stainless steel precision casting parts to be changed?
Steel deformation control is one of the most common problems in the metal processing industry. Any process will occur. The casting is the largest deformation and the least fine. It is generally used to produce blank blanks
Q:How can the casting be free of trachoma?
2, pouring temperature should be enough, otherwise the sand can not float up;
Q:How much is the amount of electrophoretic paint per square meter used in the casting?
In general, when the final thickness of 15-20 microns, cathode electrophoresis paint can be coated per kilogram of 6-8 square meters, the current general cathode electrophoresis paint for the price of 22 yuan / kg, so the cathodic electrophoresis electrophoresis paint cost at 4 yuan / square meters.
Q:Why do cheap cars like stamping parts instead of casting parts?
The difference between automobile stamping parts and castingsAs the saying goes, there will be progress in comparison. In fact, through comparison, we can find the advantages and disadvantages of both. Next, we will talk about the difference between car stamping parts and castings.Looking for national casting orders, ductile iron castings, purchasing castings, foundry orders, and consulting foundry technology issuesCasting order networkAutomotive stamping parts are widely used in every field of our life, including some electronic components, auto parts, decorative materials and so on.
Q:Cause of choking of casting parts
Choke fire is the process of pouring a large number of gases can not be discharged smoothly, boiling in the metal liquid, resulting in a large number of castings in the pores, and even incomplete casting defects
Q:What's the effect of casting copper?
Copper is one of the main corrosion resistant alloys. When the mass fraction of copper in cast iron is from 0.25% to 1%, the corrosion resistance of copper in the industrial atmosphere can be obviously increased. But copper has very little corrosion resistance in lye or salt solution.Copper can increase the flowability of molten iron and improve its casting ability remarkably.Copper can increase the coercive force and residual magnetic force, but the permeability is not affected.Combined use of copper with other alloy elements, such as copper chromium, copper chromium molybdenum, copper molybdenum, copper manganese, copper vanadium, can achieve greater results.
Q:Why should pig iron be used in casting?
Not necessarily is iron, steel, stainless steel, aluminum, copper can be cast iron, is cheaper, and better properties of cast out, for example, is not easy to rust, high strength, easy processing and so on, and is the only iron iron cast out, it is not necessarily the raw pig iron, plus some other material
Q:The casting defects of pores, trachoma how to repair?
If the repair after the high temperature resistance, choose LT737 high temperature repair agent.
Q:Why does the surface of stainless steel casting mirror mirror ripple?
Those should be head prints. If required, it would be better to throw with a single grinding head.
