- Q:How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
- Hot galvanizing doesn't seem to workThe zinc layer is 275g/ square meters of material coating is 0.019mm (mm), up to 0.08 thick.
- Q:What are the casting parts used to test shrinkage holes?
- 3 fluorescent magnetic powder, this method can also be found in part.
- Q:Can the casting part be phosphating with the phosphating solution of the pickling board?
- If it is Phosphating for painting, it is not necessary, because the surface of the casting is rough and can be firmly bonded with the paint film.
- Q:Casting parts have poor surface finish. What sand is used to make them?
- Manual coal dust, clay sand is a little worse. Mechanical styling is not bad either.
- Q:What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?

- Q:What do you mean by "proofing" in the casting? Do you charge for the proofing?

- Q:What's the effect of casting copper?
- In general cast iron, the mass fraction of copper below 3% - 3.5% can increase the hardness; but when the cast iron has a tendency to chill, or when there is a hard point of free carbides, the addition of copper decreases the hardness.Copper can be used to improve the wear resistance, abrasion resistance, and shock absorption of cast iron, so it is often used in the manufacture of sliding friction iron castings, such as drilling machine spindle, automobile and tractor, valve tappet, etc.. But in white cast iron or chilled cast iron, adding copper does not make any improvement in its abrasion resistance.Copper for certain heat resistant cast iron and austenitic cast iron can increase the heat resistance and corrosion resistance, copper - chromium composite alloy to prevent oxidation under high temperature in the atmosphere from the skin effect is particularly effective, heat resistance and corrosion resistance of austenitic cast iron containing many mass fraction of 4% ~ 7% copper.
- Q:Casting parts by shot blasting, spray painting, baking after the formation of very small rust spots, how to solve ah?
- The first process is very important. Shot blasting must be thorough. The solution is to wipe the surface of the paint with a release. Re shot
- Q:Selection of hydraulic press is the casting parts and steel plate welding, how to choose?
