4. Casting analysis
The casting is a deep cavity radiator part, there is no problem if feed water from the slider, and there are many successful cases in this layout. The reasons for the poor molding of the ribs in this case:
1: The rib is too thin, the molding distance is too far, and the speed is not enough.
2: The water flow speed on the bottom of cavity is faster than the water speed on the ribs, resulting in wrapping at the end.
5. Improving measures.
1. Use bigger machine, die trial with 1600T machine to  verify. in order to improve the gate speed, using the gate high fog forming process to see whether the effect can be achieved or not.
2.adjust the feeding angle of gate, improve the rib water speed, so that the rib and the cavity bottom wall thickness synchronous filling.
Improving measures.
