Vacuum Process Casting and Molding Line

Simple Introduction

The “Vacuum” modeling casting process is a kind of physical modeling process. None adhesives and other accessory materials shall be added into the molding sands.

This kind of casting process uses plastic film sealing sand box and molding joint, makes the sand compact by depending on the negative pressure, and makes it form into the desired cavity.

This kind of process can use wood template molds to weld the sand box by steel with short production cycle, high material utilization rate and high quality castings, which can reduce the investment by about 30~50% .

The main equipment includes vibration compacting table, film baking and covering machine, vacuum system and sand preparation system.

It is widely applicable to the casting iron, casting steel and non- ferrous metal castings.

Operating principle

vacuum process cast molding is a new metal molding technology and only adopts dry sand ( no water, binder, tagger) . It' s automatic by an electric control system.

1. Make use of the heated EVA film covering on the model to seal flask.

2. Take out the air with vacuum pump. The sand mould is tightened by pressure difference.

3. Pouring to form the casting

4. The course is physics molding way. Release little dust, so it' s eco- friendly. And the sand recovery rate can reach at 95% .

Advantages of this system

•Take good use of sand, the material recovery rate is 95%

•low cost

•good casting dimension accuracy

•save labor cost

•keep clean working environment

•eco- friendly

•save material

•reduce the labor intensity
