The process requirements of the automatic molding machine for sand compaction

The process requirements of the automatic molding machine for sand compaction:

From the casting process, the automatic molding machine has the following requirements for the compacted sand mold.

1. The fully automatic molding machine should have enough tightness after tightening, so that the sand type can withstand the movement during the handling or turning process without damage; at the same time, it must take into account the pressure generated during casting casting and solidification. Stress, due to the lack of tightness of the sand type, may cause the movement of the profile wall, resulting in dimensional deviation of the casting.

2. The sand type after the automatic molding machine is compacted should be easy to touch, and the resilience is small, and the mold precision can be maintained after the touch.

3. The sand mold of the automatic molding machine should have the necessary gas permeability to avoid defects such as pores during pouring.

With the development of society, machinery is to replace manpower. We are specialized in producing fully automatic horizontal molding machines. It has always been excellent in this industry. It has won more than 10 inventions, which is more suitable for some customers and better. Solve their problems and more effectively cater to the needs of most foundries and help them solve their problems. At present, our company's main automatic horizontal molding machine sandbox specifications are: 700mmx600m, 600mmx550mm, 600x500mm, 520mmx420m various specifications, can also be customized according to customer needs.
