Q: Casting blank in the cooling process to release a large amount of heat energy, what can be recycled?
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.
Q: How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.
The material is usually steel material price plus the cost (per ton of 2.5-3 million, plus profit).In the Yangtze River Delta region, generally 304 casting price of about 5-5.5 million / ton.The price will be higher if the parts are complex, or a piece weighs less than 100 grams.
Q: Selection of hydraulic press is the casting parts and steel plate welding, how to choose?
Casting parts in one shape, the overall processing in this regard than steel plate welding better. The same price is much more expensive than steel. Large hydraulic presses seldom have casting parts.
Q: I often see Waixiejiagong drawings, casting, how to distinguish the latheman.
Casting rough drawings generally no processing symbols, processing drawings indispensable is processing symbols!
Q: The cause of fracture and why there is no toughness
This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.
Q: What is the difference between casting and stamping parts?
Cold stamping is generally no longer done by cutting, or only a small amount of cutting is required. The precision and surface state of hot stamping parts are lower than those of cold stamping parts, but they are better than those of castings and forgings, and the amount of cutting is less.Stamping is mainly based on process classification, can be divided into separation process and forming process two major categories.
Q: Where is the precision casting factory?
Everywhere is. Look what you want to do
Q: When the blank is a casting, the margin is evenly distributed, how should rough machining?Please help friends from mechanical classes.There is another problem: in the NC milling plane contour machining, when the rough margin is large, how to deal with.Who can help in time, add 20 reward. Urgently!!
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: Which master knows how the casting tolerances for malleable iron, gray iron and ductile iron should be chosen? Hurry up, thank youCan you provide a tolerance scale for castings, please?
Our country has a national standard for casting tolerance levels. This national standard applies to you in malleable iron, grey cast iron, and ductile iron.
Q: Shandong foundry, casting small pieces of precision casting
Small foundry in Shandong too much, like many of us in Qingdao, then Dongying Changshun investment casting is a home, they are also casting precision casting equipment, specifically what I recommend that local enterprises, far is not convenient,
CMD is one of the largest manufacturers and professional exporters of forged grinding balls and cast grinding balls in China, with an annual output of 50,000 tons.
