Vacuum Casting. Vacuum casting is the process of smelting, pouring and crystallizing metal in vacuum chamber. Vacuum casting can reduce the gas content in metal to the minimum and prevent metal oxidation. With this method, special alloy steel castings with high requirements and titanium alloy castings which are easy to oxidize can be produced.
This type of open pouring method of molten metal is excellent for brass and bronze casting. This unit does not include a vacuum pump and works best with a 21CFM vacuum pump. Will take flasks up to 8" diameter x 12" high. How it works... The SuperVac will build up vacuum pressure in the lower chamber and register on the vacuum gauge.
The casting of gold and silver alloys is now carried out in a Vacuum Pressure Casting machine. The metal is melted in a graphite crucible that is heated by an induction coil. This is like a highly concentrated microwave oven. The hot mould with a perforated steel sleeve is placed in the lower chamber.

1 1/4 Gallon Vacuum Chamber Only (Requires Vacuum Pump) 1 1/4 Gallon Vacuum Chamber With Venturi (Requires Air Compressor)
casting has a crystalline structure with randomly oriented grains. With the melting chamber under vacuum, the twochamber design allows a preheated ceramic mold to be loaded into the mold chamber and the chamber rapidly evacuated. The interconnecting valve between the two chambers is then opened and the mold
The vacuum casting facility can vacuum casting metal and you can specify vacuum investment creates extremely precise cuts, angles, and designs into metals and plastics 2. It is of great importance for INDUSTRIALMAN to provide exquisite customer service.
Vacuum Assist Casting Procedure (Skip this step if using the Vacuum Chamber Casting Procedure) Casting by vacuumassist is accomplished with the use of standard solidwall flasks and the vacuumassist flask adapter. It is done on a level surface above the casting chamber. Place the 5" adapter seal (No. ) on top of the recessed chamber.

WayKen Rapid (China) provides low cost urethane vacuum casting services for making small number of plastic prototypes, offering a wide variety of materials to create PU resin parts.
In the vacuum molding process the mold are made is two parts (cope drag) with each parts attached with its vacuum chamber. The pattern is kept and a metal or wooden flask place around it. Unbonded sand is poured over the molding box, and the tables is shaken vibrantly, by which the sand particle become tight and compact.
Briefly, metal is melted in a vacuum in the lower chamber of the casting machine. The hot mold is introduced in a separate upper chamber and a vacuum is created there. Both chambers are back filled with Argon. A valve is opened and the melt is raised until the snout of the sprue enters the molten metal.
Delivery of the molten metal into the die cavity is through a gooseneck metal feed mechanism, which gives the Hotchamber die casting process its secondary name. Metals with low melting points and high fluidity are most appropriate for this process.
A wide variety of vacuum metal casting machine options are available to you, such as free samples, paid samples. There are 3,455 vacuum metal casting machine suppliers, mainly located in Asia. The top supplying countries are China (Mainland), Hong Kong, and Taiwan, which supply 99%, 1%, and 1% of vacuum metal casting machine respectively.
