Q:What is the ejection angle of the die casting (Tan Gang)?
Because after the wax, wax parts will have a slight contraction, which is good for demoulding. Many moulds don't do the ejection angle
Q:The difference between cement sand castings, resin sand castings and vacuum casting parts
The clay wet sand castings casting weight from a few kilograms until tens of kilograms, but the clay dry type of casting production can be weighed dozens of tons.For medium and large castings, cast iron, cast steel can be self hardening sand with resin can be water glass sand production, can obtain the precise size, smooth surface castings, but casting precision, surface roughness, density and microstructure, mechanical properties and material cost of sand casting production is often poor, so when the higher performance requirements of castings, should adopt other casting methods, such as casting (lost wax casting), die casting, low pressure casting.
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:Is the cast steel a casting part?
Cast steel is one of the casting parts that you call. The material is made of carbon steel or alloy steel, stainless steel, etc. the method is cast
Q:What is the difference between casting and stamping parts?
The purpose of forming processes is to allow the sheet to undergo plastic deformation without breaking the billet and to make the desired shape and size. In actual production, a variety of processes are often applied to a workpiece. Blanking, bending, shearing, drawing, bulging, spinning and rectification are several main stamping processes. The difference between stamping parts and castings: with thin, uniform, light, strong features, stamping can be produced by other methods difficult to make, with stiffeners, ribs, UPS or flanging of the workpiece, to improve its rigidity. Due to the use of precision molds, the workpiece accuracy up to microns, and repeated high precision, specifications consistent, you can punch out of the hole, lug and so on.
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:Casting parts, anodizing 20
Yes, the cast aluminium is polarized and gray, but the key problem is to guarantee the quality of the aluminium casting, and the quality of the other aluminium casting is not good.
Q:How to solve casting defect casting?
Different defects, different solutions, some shortcomings, the current domestic level can not be resolved
Q:What is the difference between forging parts and casting parts?
The forging can guarantee the continuity of the metal fiber tissue, make the fiber structure of the forging keep the same shape as the forging, the metal streamline is complete, the tissue is compact, and the mechanical property is good. To ensure that the object has good mechanical properties and long service life, the processing of objects sharp, durable, high strength, first-class quality.
Q:What should I pay attention to when designing a casting structure?
(2) in the prevention of metal mold casting misrun and cold partition should pay attention to the following problems: the structure of A casting thickness should be appropriate not too thin, especially when casting size when not too thin; the B should avoid a big level, because it makes the liquid metal in the casting. Rise slowly, and the air contact surface, easy oxidation, and because the metal type liquid metal heat quickly, quickly lose liquidity, easy to cause misrun and cold lap, slag and other defects; C casting shape should be streamlined to avoid sharp corners and has sharp change connection structure in order to facilitate the flow of liquid metal. 2 in the design of metal castings in a complex shape, if the production process is very difficult, should not affect the casting conditions, try to make the casting has simple shape, strong structure change, removed from metallic die for.
