Q: What are the casting parts used to test shrinkage holes?: 3 fluorescent magnetic powder, this method can also be found in part.

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

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.

Q: How to get rid of casting sand inside casting parts?: Are you saying that in the sand casting cavity? We use the manual blast, he is like a pipe will be automatic shot out of the grit, into the casting cavity, to remove the internal cavity in the purpose of casting sand!
