Automatic Vacuum Process Foundry Casting Molding Machine is used to produce various castings such as cylinder head, complicated pipe fittings, shell, housing, engine block, axle, brake drum, manhole cover, steel lining board etc. These casting parts are available in construction machinery, auto spare parts industry and so on.
Automatic Vacuum Process Foundry Casting Molding Machine is also called sand cast molding machine, vacuum seal casting molding equipments line, vacuum process molding and so on. It is a kind of dry sand casting molding machine which adopts no adhesive and based on the pressure produced by the vacuum pump, the pressure compacts dry sand to the needed shape. Filled dry sand(without adhesive, no mixing) in the flask, both sides of flask are covered with plastic film, and evacuated air inside, under a certain vacuum condition sand will lose relative motion, and then forming a mold.1. Produce burr-free castings without draft angle, thus minimized machining
2. Achieve a highly reproducible moulding result within narrow tolerances
3. Dimensional accuracy
4. Reduce shrinkage and porosity of casting
5. Achieve flat surface geometries without bending and without cracks
6. Control the cooling process by activating/deactivating the vacuum
(reduction of residual stress and elimination of shrinkage holes)
7. Cast outstanding surface qualities
8. Reduce pattern wear (mainly use of wooden patterns possible)
9. Reduce life-cycle equipment cost compared to chemical-bound moulding
10. Increase output compared to chemcial-bound moulding by degree of automation
11. Reduce environmental impacts (no sand reclamation plant, less sand losses)
12. Eliminate gases from cores and metal during pouring to gain tight micro structures
