Q:What are the requirements for casting steel castings?
1, high quality requirements of the surface or the main processing surface should be placed below.
Q:General aluminum alloy die casting or casting box and other parts,
If it is not directly cast hole hole, later processing, large pores may be directly cast out,
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:Lathe processing stainless steel casting parts to use what type of tool, the speed into the amount of how much tool angle
It has something to do with the size of your work, and it has a lot to do with the blade you're using right now.
Q:What foundry factories are used in the casting parts of China's major automobile manufacturers?
This is too muchYou do not have a specific list of statistics, but there are many foundries in china!Moreover, car prices are unlikely to be ordered in the local factories!
Q:When the blank is a casting, the margin is evenly distributed, how should rough machining? Twenty
Even distribution is a good thing. Generally, the machining allowance of the casting is uneven.If the processing depends on how your processing techniques have been arranged.In the NC milling plane contour machining, when the rough margin is large, how to deal with.1. Return to the foundry, too large margin improvement.2. Then you can spend more time on it.
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:Can the casting part be phosphating with the phosphating solution of the pickling board?
Like stainless steel casting, duplex stainless steel casting is phosphating, ductile iron gray iron is not required
Q:When there is no flaw detection for large casting parts, is there any crack inside?
According to the industry standards, within the scope of the standard requirements to determine whether the product is qualified
Q:How to collect exothermic process of casting blank?
Casting, do not need to provide a rough casting foundry drawings, according to your chart will put foot margin in the processing needs of the surface, the rest of the size can be found according to the mechanical design manual and manual casting. General Casting Factory Casting Division will be in your chart marked on shrinkage and processing margin figure (usually with red and green pen) to the patternmaker production of wood or other material mould diagram.
