- Inquire about price/MOQ

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:How can the casting be quenched and tempered?
Another is the result of pre heat treatment (quenching or annealing) after quenching and tempering treatment, suitable for ZG35SiMNMo, ZG35CrMo and so on. Please tell the casting process is your product and material and then set tempered.: shutup:
Q:What are the casting parts used to test shrinkage holes?
2. x ray. This method can do nondestructive testing, but the cost is higher. Generally, high castings are required.
Q:We are small castings, the need for surface treatment of shot blasting machine, about how much?
according to the comprehensive consideration of factors such as yield, size of workpiece commonly used on the market the crawler shot blasting machine has Q324, Q326, Q328, Q3210, and each time the amount of their treatment were 125KG, 200KG, 400KG, 600KG, the specific use of what types also need to be determined according to the actual situation
Q:General aluminum alloy die casting or casting box and other parts,
Single for this problem, the direct casting out of course good. But many times because of the limitations of the process, so we choose the post-processing hole
Q:The casting sand is going on
2, causes(1) sand mold (core) strength is not high, when the box a little reason will fall off.(2) the strength of sand mould (core) is not high, it can not stand the erosion of molten steel.(3) box sand mould (core) crush.(4) high strength under high temperature, warpage, deformation and protuberance into the cast steel under the action of high temperature molten steel.(5) the floating sand in the air hole of the sand mold falls, especially when the floating sand falls in the casting, and the floating sand on the surface of the sand mold is easy to fall through the air vent.(6) when the box is closed, the surface of the mold cavity and the surface of the sand core are not cleaned, and the sand (core) surface has floating sand and so on.
Q:When the blank is a casting, the margin is evenly distributed, how should rough machining? Twenty
Personal advice:Because of the large margin, your outline is easy to guarantee;So the key is to consider the assembly and aesthetics of the casting. You have to find the machining criteria;Rough the datum so that it can be machined;After the outline, turn back to the finishing line.If the casting requirement is not high, the benchmark can be directly processed; (not recommended)Over
Q:What is the ejection angle of the die casting (Tan Gang)?
Because after the wax, wax parts will have a slight contraction, which is good for demoulding. Many moulds don't do the ejection angle
Q:Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!
Increase the refractoriness and looseness of core sand
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
