Q:Why does the precision casting factory not usually make iron castings?

The so-called precision parts is the size, roughness requirements of the piece. Cast iron parts generally do not reach the accuracy.

Q:Why do cheap cars like stamping parts instead of casting parts?

Separation process is also called blanking, the purpose is to make the stamping parts along a certain contour line from the sheet metal separation, at the same time guarantee the quality requirements of the separation section. 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:As shown, how do I achieve the tightness test of this product, and achieve industrial production? Seek expert advice.

Precise and tight sealing of the surface to which the test piece is to be tested, equipped with an airtight test instrument, and an electrical control system. You can complete automated testing equipment

Q:What are the requirements for casting steel castings?

1, high quality requirements of the surface or the main processing surface should be placed below.

Q:My parts complex, machining costs are relatively high, so want to cast, but the surface needs anodizing, what material will be better?

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 can the casting be free of trachoma?

Measures for the prevention of trachoma in castings:1, sand compaction to high, paint two times;

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:The difference between sheet metal and casting parts

Commonly used in machine tools casting material is gray cast iron, casting bearing alloys can also be.

Q:After reaming, the roughness can reach several levels, that is to say, the sample.Casting parts in rocker arm drilling, reaming, roughness, block. After reaming, the roughness can reach several levels, that is to say, the sample.

Not processed, do not understand your problem... There's something wrong with the drilling machine. Please call me

Q:There is a little trace of polishingShock polishing is even worseElectrolysis can not be uneven, there is a slight bump

Use the vibrator to polish the material: the high aluminum porcelain 4cm (with a polishing agent that has an automatic mending function), you go find this polish,
