The main Vacumm casting process shell are:
1) degreasing and degreasing of modules.
In order to improve the ability of the coating surface, the oil stains on the surface of the mould should be removed.Vacumm casting.
2) apply paint and sand on the module.
Smearing paint before, should first coating and minimize paint barrels of refractory precipitation, adjust good paint viscosity or density, so that the coating can pack well and wetting moudle, hanging coating, soak your module in the paint, or shake, can make the paint is very good wetting moudle, evenly covering the surface of the group.When the coating is coated, sand can be carried out.CNC machine .
3) drying and hardening of the shell.
After each coating of the shell, it is necessary to dry and harden it, so that the binder in the coating from the gel to gel, gel transformation, the refractory materials together. tooling .
4) melting and loss of mold in the self-type shell.
When the shell is completely hardened, it needs to be melted away from the shell, and it is also called dewaxing.According to the different heating methods, there are a lot of dewaxing methods, which are mainly used in hot water and the same pressure steam method.rapid prototypes .
5) roasting rapid prototypes shell.
If the molding (sand filling) is needed, before the roasting, the molds in the moulded shell of the moulded shell will be removed before the furnace roasting.If the shell has a high temperature strength and no moulding is needed, the moulded shell can be fired directly into the furnace.Gradually increase when roasting furnace temperature and heat type shell to 800-800 ℃, heat preservation for a period of time, can be cast.
