Q:What is the reason for 304 stainless steel precision casting parts to be changed?
Mainly because of the cooling shrinkage caused by internal stress caused. There is the change of temperature distribution in materials element imbalance, is typical of surface and internal, thin wall and thick wall, bottom and top.
Q:What method of casting does not rust? I think the sample is like oil
Close to the solder, and slowly dissolve is hot melt double-sided adhesive, otherwise it is oily double-sided adhesive.
Q:What is the difference between forging parts and casting parts?
No, it's called die castingDifference: the die casting parts are simple in structure and large in batch sizeCasting: the use of a wide range of structures without restrictions
Q:How to calculate the price of casting parts?
Cost of raw materials + electricity (fuel) costs + workers' wages + managers' wages + transport costs + raw materials burned + accessories costs + equipment maintenance depreciation costs + management fees + tax. The most convenient, the raw material market price plus 2000 yuan, plus you want profits on the line.
Q:Heat treatment process and purpose of casting parts
Objective: to stabilize tissues, eliminate or substantially reduce internal stress.
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:Explain the heat treatment effect of casting parts, forging parts and welding parts
2 improve the crystal structure, enhance the formation and stability of spherical carbon crystal;Forgings are generally stress bearing members, and most of them are made of high strength medium carbon steel (alloy), which is formed by forging and fine crystalline. After the shell is annealed or quenched and tempered, the mechanical properties of the shell are more superior, and it has better strength and better elasticity;Welding materials.
Q:General aluminum alloy die casting or casting box and other parts,
You need to confirm what you use tap processing, so as to determine the size of the casting hole
Q:Casting pieces of plastic processing requirements can not fall off the skin,
Steel parts are not familiar. But after spraying, the powder should be divorced from the adhesive force is too low, try to provide the surface roughness of the casting
Q:How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
Hot galvanizingGenerally 0.06 mm or more
