Q:Why do cheap cars like stamping parts instead of casting parts?
We usually say that the stamping is usually refers to the cold stamping parts, for example, a piece of iron, wants to turn it into a fast food dish, it must design a set of mold, mold is working face plate shape, the pressure plate mold, it becomes you want the dishes, this is the cold stamping die stamping is the direct use of metal materials.Automobile stamping parts are mainly classified according to process, and can be divided into two major parts: separation process and forming process.
Q:What are the casting parts tested?
The surface brightness, appearance, size, chemical composition, weight, material, surface defects, internal defects, seals need to be checked, leakage, etc.
Q:How to improve the surface roughness of casting parts?
First, the accuracy of the model should be improved; two is to change the molding technique; the three is the coating; and the worker's technical level.
Q:What's the density of casting?
Uneven casting density is caused by uneven shrinkage of the casting during solidification.
Q:What are the casting parts used to test shrinkage holes?
2. x ray. This method can do nondestructive testing, but the cost is higher. Generally, high castings are 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:What are the factors affecting the machining process of the casting material and structure?
The impact on the machining is obvious, it should be the material and heat treatment of the castingCarbon steel parts should be treated by heat treatment (annealing) without special conditions. It can effectively prevent the uneven hardness and hard points. It is easy to turn.
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 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:How can the casting be free of trachoma?
3, the gate is not facing sand core, flush sand core, will cause trachoma.
