V-process casting line / Vacuum sealed molding line

PRODUCT INTRODUCTION

1.Vacuum sealed molding is a new modeling process, use single dry sand (don't add water, binder and affix) for molding sand, with plastic film after heating with a vent and suction device on the shape of the coated forming, sealing the flask, and relying on the vacuum to pump out of internal air, causing the internal and external pressure difference compelling the dry sand to get tight, to form the required cavity with a physical modeling method.

2.Our company has the world's leading V-modeling technology, according to the user's different requirements of castings, design and manufacture different specifications of the V-modeling equipment, and matched sand processing equipment.

3.It's basic equipment is: sand box template with suction filter tube, vacuum system, plastic film heating, molding and cut off, jolt compacting platform and sand processing equipment.

4.Vacuum sealed molding process with its high degree of automation, casting high-quality, high precision and pollution-free, energy conservation, improve the labor environment, etc., in recent years has been developed by leaps and bounds.

V-process casting technology:

1. Film heating: using special film heat to heat the EVA film to certain temperature.
2.Film covering: turn on the pattern vacuum, put the soften film on the pattern surface. The film will covered on the pattern surface tightly underthe effect of vacuum.
3.Coating spraying: spraying the coating through coating spraying system on the film surface. Using drying machine to dry the coating.
4.Flask setting: put the empty flask on the pattern.
5.Sand filling: vibrating table move to sand filling position. Turn on the sand filler, sand flow into the empty flask and under vibration to get high density mold.
6.Film sealing: put another piece of film on the back surface of the mold. Turn on the vacuum, the mold become hard.
7.Stripping: after get hard mold, using special lift machine or manapulator for stripping and close the mold on the pouring area.
8.Pouring: pouring under vacuum pressure. Then keep certain time of vacuum. After keep vacuum pressure,
9.Shaking out: turn on the vacuum, move the mold to shaking out area, then turn off the vacuum. The sand flow freely and back to sand hopper through sand preparation system.

● Characteristics& Advantages of v-process casting technology
.1.V-process using dry sand without any chemical binder, under the vaccum pressure to get stable mold;
.2.No chemical binder consumption can reduce the production cost;
.3.No pollution, environmental friendly;
.4.Excellent surface quality (Ra12.5);
.5.High dimensional accuracy;
.6.Suitable for all kinds of metal materials;
