v Anti corrosion,water, dust and pets tight, well sealed prevent poisonous gas leaking out.
v Without displacement, freely radio signal passing.
v Higher and lower temperature tolerance with the range -40°C-200°C.
v Wear indicators available when thread depth is in a danger value.
5. Free design
v Much more clear resolution ratio of surface design than cast iron or BMC.
6. Carbon footprint saving and environmental care.
v Lower embedded energy carbon emission and during manufacturing process than cast iron covers.

- Q: There is a little trace of polishingShock polishing is even worseElectrolysis can not be uneven, there is a slight bump
- German winter three step mirror polishing 2013 new processYou can free proofing!
- Q: What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?
- According to the requirements of the workpiece annealing, there are many kinds of annealing process specifications, such as full annealing, spheroidizing annealing and stress relieving annealing. Steel the steel quenching is heated to the critical temperature Ac3 (hyposteel) or Ac1 (hypereutectoid steel) above a certain temperature, holding time, so that all or part of 1 Austenitic, then the cooling rate is greater than the critical cooling rate of fast cooling to below Ms (or near Ms isothermal) of martensite the body (or bainite transformation) heat treatment process. Aluminum alloys, copper alloys, titanium alloys, tempered glass and other materials are usually treated by solid solution or heat treatment with rapid cooling process. Tempering is a heat treatment process where the workpiece is hardened and heated to a temperature below AC1, which remains cool for a certain period of time and then cools to room temperature. Tempering generally followed by quenching, the purpose is: (a) to eliminate the residual stress caused by quenching, prevent deformation and cracking; (b) hardness, strength, plasticity and toughness of workpiece is adjusted, to use performance requirements; (c) the size of organization and stability, ensure the accuracy improvement; (D) and to improve the processing performance. Tempering is therefore the last important step in obtaining the desired properties of the workpiece. According to the tempering temperature range, tempering can be divided into low temperature tempering, medium temperature tempering and high temperature tempering. This answer is recommended by the questioner
- 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: 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: 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's the density of the cast iron? The density is thin and the density is thin
- Generally cast iron thick place, density is empty, thin place density a little more.
- Q: How to cast iron and wrought iron collocation
- 3, if you have a file in the hand, can be used to file to see finish can also make a judgment from the file down the iron can also be seen, but this is beyond your request, it can be done in the factory. 4, if placed in the grinder grinding, see iron spark from a judge or iron wrought iron, but this is only to do in the factory. About it, may not be full, but through these methods, generally can distinguish between iron or wrought iron.
- Q: Why do casting parts have air holes?
- Cangshan Qiao hidden his answer is quite comprehensive, you can try using inert gas to reduce air cover
- Q: Where is the precision casting factory?
- Everywhere is. Look what you want to do
- 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.
