- Q: Why does the precision casting factory not usually make iron castings?
- The so-called precision parts is the size, roughness requirements of the piece. Cast iron parts generally do not reach the accuracy.
- Q: Casting parts need to be subjected to the kind of heat treatment after the weldment is finished
- Annealing is needed to eliminate stress and refine grain
- Q: How do casting parts remove stress?
- Annealing treatment, according to different casting annealing treatment, eliminate thermal stress, if need to restore hardness or increase hardness, and then quenching treatment
- Q: It is generally said that cast iron is re smelted by pig iron. My question is..:1 pig iron for melting iron, is directly cast into products (such as bed cover, etc.); or that is just the first pig iron smelting iron casting, such as to cover, bed and other products, will once again cast iron melt to casting?2, there are many castings to the engine. Are these castings made by the engine manufacturer themselves or bought by others?There is no need to answer all. Thank you！！！
- The first to ask, such as casting end cover, bed and other products, is to put the iron melting and casting againThe two question, their casting castings manufacturers than to buy professional casting factory production, production quality more security professional.
- Q: I often see Waixiejiagong drawings, casting, how to distinguish the latheman.
- Yes, casting drawings are casting drawings with machining allowances, slopes, and gating systems
- Q: What are the causes of pitting on the surface of a precision casting?
- The quality of the shell surface is out of order. Or shot blasting out of question.
- Q: As shown, how do I achieve the tightness test of this product, and achieve industrial production? Seek expert advice.
- Precise and tight sealing of the surface to which the test piece is to be tested, equipped with an airtight test instrument, and an electrical control system. You can complete automated testing equipment
- Q: What do you mean by "proofing" in the casting? Do you charge for the proofing?
- Proofing? In the casting industry is not called proofing, proofing is generally used in the printing industry, that is, according to the customer's drawings or samples, to do a first piece, to provide customers with the inspection process to meet their requirements;In the foundry industry, providing prototypes is sometimes difficult:1, customers if the provision of mold, it would be best, at this time, sample costs are very low, and almost the same as your regular products;2, the customer does not provide the mold, but in business relationships, your factory and not very sure must take this one, it requires your leadership decision-making, is free or low cost, or by a strict process offer (of course sample);3, not all of the casting process to provide samples are difficult, like lost foam can directly make a white NC prototype, and then assembled pouring, this is her unique advantages, first cost less than the opening process and so on;If you don't understand, you can continue to question me
- 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 reason is the bronze statue choking fire?
