1.Casting information
Casting name: unknown
Casting requirements:internal requirement
Casting process: 
Die Casting machine tonnage: 160
alloy material: A380
2. Casting problem
machining porosity on the end surface of the ejector die half (mainly concentrated under the ribs). The ribs were added to avoid sticking to the cover die half.

4. Casting analysis
①The main problem is that the binding force of the cover die half is greater than that of the ejector die half. In order to increase the binding force of the cover die half, the process ribs are increased, resulting in the porosity caused by overwork of processing .
②The two side gates flow too fast, which is easy to prematurely block the end exhaust gas and affect the exhaust effect.
5. Improving measures
①The problem of clamping force of the ejector  die is solved by arranging crochet on the surface of the ejector die and removing the process ribs and reducing the processing amount.
②Optimize the runners: change the original four gates to two, adjust the filling Angle and redefine the 5 overflow exhaust positions, so that the air in the cavity can be maximized discharged to achieve the improving effect.

6. Tips
For the machining surface.
For the surface that needs to be machined, it can be used to arrange elements conducive to production, such as the ejector pin, gate, barb, etc.
