Cast aluminum manufacturersIt is pointed out that the analysis and research of casting defects is one of the key technologies to improve the output of castings. However, its difficulty is not small.BelowCast aluminum manufacturersLet's talk about the difficulties.

its difficultyMainly in the following four aspects:

1,A wide range of knowledge is involved, such as alloys, casting technology, modeling materials, casting equipment and production process testing.

2、There are many reasons for casting defects. One type of defect may be caused by multiple reasons, and one cause may cause multiple defects.

3,Limiting technical measures, such as taking measures.-1-To prevent one type of defect, but may cause another type of defect.

So...When the shrinkage of the casting in the mold is only affected by the frictional resistance between the metal surface and the mold surface, it is free shrinkage. If the shrinkage of the casting mold in the mold is also hindered by other obstacles, the copper casting is called hindered shrinkage. For the same alloy, the hindered shrinkage is less than the free shrinkage.

Cast aluminum manufacturersIn orderPrevent casting shrinkage and porosityUsedThe basic principle is to develop the correct casting process for the shrinkage and solidification characteristics of the alloy so that the casting can establish good shrinkage conditions during the solidification process and as far as possible. The shrinkage rate is converted to a shrinkage rate. Holes and shrinkage occur during solidification of the casting. In this way, the cast aluminum manufacturer places a certain size of the riser at the location where the casting solidifies, and the aluminum casting concentrates the shrinkage cavity in the riser, or opens the gate at the solidification location to feed directly. Cast aluminum manufacturers in orderGiveCasting solidification provides good feed conditions, the main reason is to control the direction of casting solidification, so that it conforms to"Principle of Directional Solidification" or "Principle of Simultaneous Solidification".

Cast aluminum manufacturersRight.The introduction position of the gate system has an important influence on the temperature distribution of the casting. Adjusting the casting temperature and casting speed of the liquid metal can enhance directional solidification or simultaneous solidification.
