Gravity Casting Machine

Introduction

The grille of Gravity Casting Machine is transferred from the flap to the memory chip holder, and the rotating bed pushes the grille back. When the grid length changes, the adaptability to the storage shelf can be adjusted. Secondly, our products use time pressure to fill the material, and the lead mouth and lead spoon are heated by electric heating tubes, automatically controlling the temperature. The system is simple, reliable, easy to use and maintain. More importantly, our circuits are all controlled by PLC, the data setting adopts touch screen, the electrical components are imported from abroad, and the hydraulic components are also imported from abroad. Finally, our products are cheap and of high quality, which are deeply loved by customers.

 

Feature

The Gravity Casting Machine use long cutters and lower positioning mechanism to ensure that the equipment can work in a large range. The grid moves forward from the mold to the conveyor, through the tablet roller and the delivery roller, and then into the cutter. Secondly, our position is controlled by the lower positioning mechanism. So this is a process without impact. With this, the problem of mesh deformation is solved. This is very important for thin grid casting. By using a long cutter, the mechanism will ensure that the equipment works in a wide range. Finally, our products use PLC and touch screen to control the whole system, which makes our system very stable and reliable.
