vacuum sand molding machine for casting

 

  

 

HOW IT WORKS 
First, we heat a thin plastic film and place it over a pattern. A vacuum tightly draws the film over the pattern, 
which is then surrounded by a flask.

Next, we fill the flask with dry, unbonded, extremely fine sand and 
vibrate the sand so that it tightly packs the pattern.

After a second sheet of film is placed on the flask, a vacuum draws out the air, and the completed mold is then stripped from the pattern. 
Each half of the mold is made in a similar fashion and then aluminum is poured directly from the furnace 
into the closed halves. The mold is held under vacuum to retain its shape. After the mold cools, the vacuum 
is released and the sand and completed castings fall free. 
Simple in concept and far reaching in impact, V-PROCESS produces quick turn-around, high-value castings. 
In order to provide the highest quality product, Harmony Castings continually strives to improve our systems 
and raise the level of our performance. To achieve these standards, we maintain ongoing training programs 
that teach our employees to accept responsibility and to act on their knowledge.

The caliber of our people and the quality of our V-PROCESS make it possible for Harmony Castings and TPi create a vision for the future, and to establish our Company as a leader in the casting industry. 
It is no accident that major companies in the medical, instrumentation, electronics, computer and telecommunication industries rely on the V-PROCESS for their casting needs.
