Product Overview
Description
Vacuum processing SG casting moulding foundry machine
Features:
- Higher quality and lower cost: Smooth cast surfaces and excellent dimensional accuracy significantly reduces the subsequent finishing process and reduces the machining cost.
- High production efficiency: Sand filling and disassembly are easier than with the self-hardening process and the sand can be recycled.
- Environmentally friendly: The use of dry sand containing no binder leads to environment-friendly casting with less wastes and hazardous gas emissions.
The proceduer of V technology
1.A pattern is placed on a hollow carrier plate in advance. Then we heat a thin plastic film (.003″ to .008″) and place it over the pattern.
2.When the softened film covers a pattern, a vacuum (200 to 400 mm Hg) draws it tightly around the pattern, which is then surrounded by a flask.
3.Next, the process uses dry, free-flowing, unbonded sand to fill the special flask set over the film-coated pattern. (*The sand used contains no water or organic binders and is kept under a vacuum during molding.)
4.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.
5.Each half of the mold is made in a similar fashion and then casting is poured directly from the furnace into the closed halves.
6.The mold is held under vacuum to retain its shape. After the mold cools, the vacuum is released and the sand and completed casting falls free.
