Q:What is the difference between forging parts and casting parts?
The casting parts are low in cost and short in production period. Because the molten iron has good flow properties, complex shapes can be formed. But because there may be sand holes, pores, shrinkage holes and other defects, the quality is unstable, easy to produce many defects, mechanical properties are not forged well, thus affecting the service life.
Q:Shandong foundry, casting small pieces of precision casting
Dongying Huayang precision casting factory, the smallest to do 2G pieces.
Q:How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.
Yantai five God casting is generally 53 yuan /kg, the appearance is quite beautiful
Q:What's the effect of casting copper?
Copper is one of the main corrosion resistant alloys. When the mass fraction of copper in cast iron is from 0.25% to 1%, the corrosion resistance of copper in the industrial atmosphere can be obviously increased. But copper has very little corrosion resistance in lye or salt solution.Copper can increase the flowability of molten iron and improve its casting ability remarkably.Copper can increase the coercive force and residual magnetic force, but the permeability is not affected.Combined use of copper with other alloy elements, such as copper chromium, copper chromium molybdenum, copper molybdenum, copper manganese, copper vanadium, can achieve greater results.
Q:The cause of fracture and why there is no toughness
This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.
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 angleEspecially deep hole, and customers to discuss, generally take 0.3-1 degrees is enough
Q:How much is the amount of electrophoretic paint per square meter used in the casting?
It was a very simple question, and it was complicated by what you said.In general, when the final thickness of 15-20 microns, cathode electrophoresis paint can be coated per kilogram of 6-8 square meters, the current general cathode electrophoresis paint for the price of 22 yuan / kg, so the cathodic electrophoresis electrophoresis paint cost at 4 yuan / square meters.
Q:The casting sand is going on
2, causes(1) sand mold (core) strength is not high, when the box a little reason will fall off.(2) the strength of sand mould (core) is not high, it can not stand the erosion of molten steel.(3) box sand mould (core) crush.(4) high strength under high temperature, warpage, deformation and protuberance into the cast steel under the action of high temperature molten steel.(5) the floating sand in the air hole of the sand mold falls, especially when the floating sand falls in the casting, and the floating sand on the surface of the sand mold is easy to fall through the air vent.(6) when the box is closed, the surface of the mold cavity and the surface of the sand core are not cleaned, and the sand (core) surface has floating sand and so on.
Q:Why should pig iron be used in casting?
Cast iron is generally called pig iron, but casting is not merely iron casting.For example, injection molding, die casting, and so on, in fact, cast iron, cast steel, cast aluminum, plastic and so on, can be used in the form of casting processing molding
Q:What is the difference between the casting drawing and the car work drawing?
Yes, casting drawings are casting drawings with machining allowances, slopes, and gating systems
