Q:Can the casting part be phosphating with the phosphating solution of the pickling board?
Phosphating. But it's not necessary. Because casting parts have strong corrosion resistance.
Q:What are the casting parts tested?
The surface brightness, appearance, size, chemical composition, weight, material, surface defects, internal defects, seals need to be checked, leakage, etc.
Q:What's the density of casting?
Uneven casting density is caused by uneven shrinkage of the casting during solidification.
Q:Heat treatment process and purpose of casting parts
Objective: to stabilize tissues, eliminate or substantially reduce internal stress.
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:Is 316 casting better than 304 casting?
It is comprehensive. There is no simple comparison of the material to determine the degree of difficulty in processing
Q:What reason is the bronze statue choking fire?
The casting process in boiling phenomenon, is the setting of the exhaust hole positioner position or number is not reasonable, the air cavity can not be discharged, overwhelmed by a material inlet, reflux, change mould, sincerely help you look forward to adopt,
Q:How to improve the surface roughness of casting parts?
One is to improve the accuracy of the model; the two is to improve the molding sand mesh. How much is the other relationship?.
Q:How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.
