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!
If is casting, internal shell mold may be not completely dry, strength is not enough, resulting in shell mold collapse into molten steel.It is also possible that the refractory is not refractory enough.
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:How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
Hot galvanizing doesn't seem to workThe zinc layer is 275g/ square meters of material coating is 0.019mm (mm), up to 0.08 thick.
Q:What foundry factories are used in the casting parts of China's major automobile manufacturers?
For example Changchun FAW, under a casting, two casting and other casting plant, but there are more than half of all outsourcing in Tianjin Hebei Shandong purchase, many automobile enterprises to casting foundry.
Q:How to distinguish the forging parts and casting parts accurately
To distinguish from the use of materialsForging materials are mainly made of carbon steel and alloy steel of various components, followed by aluminum, magnesium, titanium, copper and their alloys. The original state of the material is rod, ingot, metal powder and liquid metal. The materials needed for casting are mostly metal, wood, fuel, molding materials and so on. In contrast, the forging parts rarely produce dust, harmful gas and noise, etc., and play a more obvious role in environmental protection. Of course, because of this, the price of forged parts on the market is higher than that of castings.
Q:In theory, which is more expensive, forging parts or casting parts?
It depends on the structure. In theory, the shape of the forging is relatively simple, but the requirement of internal structure is relatively high
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:Stainless steel mirror polishing precision casting parts is very difficult, 20
German winter three step mirror polishing 2013 new processYou can free proofing!
Q:Sealing test of casting parts 5
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:When there is no flaw detection for large casting parts, is there any crack inside?
