Die Casting Manufacturer Help You To Solve The Problem Of
Sag


The concave and flat part on the smooth surface of the die
casting is naturally cooled. The following Die Casting Manufacturer
https://www.chinaweilong.cn/ will introduce
it for your analysis.

Cause:

1. The structural design of die castings is unreasonable, with
local thick parts and hot spots.

2. The alloy shrinkage rate is large.

3. The cross-sectional area of the ingate is too
small.

4. Be lower than others.

5. The mold temperature is too high.

Resolution:

1. Improve the die casting structure to make the wall thickness
slightly uniform and the joints with large thickness difference should gradually
ease the transition and eliminate the hot spots.

2. Select the alloy with small shrinkage.

3. Properly set up the gating system and appropriately increase
the cross-sectional area of the ingate.

4. Increase the injection force.

5. Adjust the heat balance condition of the mold properly, adopt
temperature control device and cooling, etc.
