History of V process investing casting foundry machine

•From 1970s , China introduced the vacuum process casting technology and put this equipment into production. From that time we began to produce this equipment by ourself.

Our factory is a leading company in theV-Process casting machineproducing field. We have 7-10 people professional technical team and strict quality control system. We sincerely hope to cooperate with home and abroad customers.

Process & Operating principle

V-process investment casting machineis only adopt dry sand (no water ,no binder,no tagger).

Then take use of heated EVA film covering on the mould to seal the flask.

After taking out the air from the flask by the vacuum pump,the sand mould will be tightened by the pressure difference.

Pouring to form the casting, in this period , keep the flask in the vacuum state.

This process use no chemical material ,it release little dust and low noise, so it's a physics molding way.

Also it's an efficient and cost-effective Machine.

Technology process

Heat the EVA film
Cover the heated EVA film on the mould(can be made from wood or aluminum)
Spray a coating in a certain baume degree
Put on the empty blask
sand-up the flask and vibrate to compaction
cover film on the full flask
vacuate the sand flask
lift flask
mould assembling
vacuate the whole mould
pouring
loose sand flask
