Vacuum process casting equipment is well used in large size casting's production. It has great advantage in making counter weight, wear-resistance parts, and so on. The sand is totally dry without any chemical.
Vacuum process casting molding equipment
Advantages:
Mold filling rate during pouring process is higher by 25-30% than during greensand mold filling.
The mold provides for a minimum pouring temperature for metal due to the high filling rate and heat capacity.
The lowest production cost of casting, by 25-30% lower, than the castings made with sand molds and by times lower in cost than traditional cold-hardening mixtures casting –
the best solution for mass-production of castings.
No necessity to prepare the sand mixture – the process is carried out with dry sand.
No waste products, sand mix regeneration system and eco-friendliness.
Possibility to produce thin-walled steel castings.
Long service life and high durability of patterns, no contact between the pattern and the sand (only through film, which excludes the possibility of quick wear).
Minimum raw material consumption.
Considerable decrease in the prerequisites for ‘hot cracking’.
High-temperature castings knock-out capability.
Less cost for thermal treatment of ready castings.
No need for additional/further training of operators.
Production process:
prepare the mold pattern
heat the EVA film
cover the EVA film on the surface of the mold pattern
put the empty cope/drag box
fill the sand into the box
cover the surface film
vibrating and compact the sand
pin lift the sand mold.
do the same process making the drag
combine and close the sand box.
