Q: How to calculate the price of casting parts?: According to the complexity of the workpiece, material and casting requirements and process yield

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: Domestic large steel castings factory which is better, recommend!: Do the casting manufacturer of large steel castings, Hunan Jinsha heavy industry science and technology limited company, heard that their professional only more than 1 tons of steel castings, anyway, 150T just big, the company won a lot of foundry industry patents should be good.

Stamping is a highly efficient production methods, the use of compound die, especially the multi station progressive die stamping process can be completed in a multi machine, realized by belt uncoiling, leveling, punching, forming and finishing automatic production. High production efficiency, good working conditions, low production costs, can produce hundreds of parts per minute. 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 straightening are the main types of stamping machines.

Q: It is generally said that cast iron is re smelted by pig iron.

Q: What's the density of the cast iron? The density is thin and the density is thin: Uneven casting density is caused by uneven shrinkage of the casting during solidification.

Q: For example, casting parts contain many holes, inclusions and other defects, the size and the number of holes exceed which limit is not qualified: For example, the castings shall be in accordance with the requirements of the second types of castings in the technical requirements for aluminum alloy castings of GB/T9438-1999;

Q: Can the casting part be phosphating with the phosphating solution of the pickling board?: Like stainless steel casting, duplex stainless steel casting is phosphating, ductile iron gray iron is not required

Q: Lathe processing stainless steel casting parts to use what type of tool, the speed into the amount of how much tool angle: What kind of work, what kind of material, 204201304316, how big live ah? You ask?Can the 201 pieces of material and 304 of the pieces fit in a single car? Can I use the universal YG8 knife?
