The dimensional precision of the die casting.

The dimensional precision of the die casting is high. It is the crown of all kinds of casting methods, and its stability (the time of keeping this precision) is also very good. It is basically based on the machining precision of the die casting die. But there are many factors that affect the accuracy of die casting, and they are interrelated and influenced. These factors are mainly caused by the deviation of the chemical composition of the alloy itself, the shrinkage rate is different, the degree of deformation is different, the calculated shrinkage rate is deviant from the actual shrinkage of the alloy; the design structure of the casting is not reasonable, such as the casting thin and no reinforcement, which leads to the deformation or cracking of the casting when the die is ejecting, and the wall thickness is not uniform. In the casting, the shrinkage is not consistent and the internal stress is different. The casting is less inclined and the mold difficulty is increased; the deformation or fracture causes the dimensional accuracy, the opening and the core pulling, the stability of the movement state of the mechanism, the error caused by the grinding loss in the mold use process; the die casting process reference. Deviation of the number, error caused by the precision and rigidity of the die-casting machine; the error produced by the number of moulds, the deviation of the calculation and manufacture of the forming parts; improper selection of the mold material, the core pulling and the introduction of the mold; the position of the casting in the mold (i.e. the improper selection of the type surface); the casting die temperature, the injection velocity and the ratio of the casting. The work of pressure, time, coating thickness and so on Technical factors will affect the dimensional accuracy of die castings.


1. this product is smooth and large, requiring no pitting and scratching on the surface. Is that possible?

This is a little difficult, because the products of the alloy will have this kind of unavoidable phenomenon. It needs a standard sample to make the goods. With our experience, we suggest that you can spray sand on the surface of your company. The products we've done before are all sandblasting. I can send you a sample to show you the effect. It is very good.

2.ADC12 be welded with aluminum profiles? Is it strong enough to bear?

We have tried that ADC12 can be dumb argon welded with aluminum profiles, but there will be pores at the weld, because of the density of the reason, bearing a large force will also fracture. So you need to do your tension test.

3.Is there any difference between 9. powder spray and paint? Which is better?

There is a difference. One is powder and the other is paint. We think the effect of powder spraying is better. Because the cost is high, the wear resistance is strong. 

4. can you make a high precision product? Is there a five axis CNC? 

Our 3 axis and 4 axis CNC, you say the precision is how, we can usually do positive and negative 0.1MM, if a special size 0.03-0.05MM is a bit difficult to do CNC processing, but if you want to electroplating, the size of this size is not well controlled. And the cost is very high.

5. for the products of aluminum alloy, please quote the price?

Yes, do you have a three D chart? Please provide the drawings and let me have a look at the project.
