Vacuum Furnace

gold silver bullion making machine

The vacuum furnace is equipment for heating and melting types metals  in vacuum conditions. Vacuum furnace is mainly used for , vacuum melting, vacuum heat treatment, annealing, brazing of metal parts, metal grians& powder making. Cooldo can provide a variety of customized vacuum furnaces.

Function:

1: Vacuum melting furnace: melting all kinds of metals and metal alloys in a vacuum condition. The vacuum-closed environment can prevent oxidation and achieve the best quality metal castings.

2. Vacuum heat treatment furnace can be used for vacuum quenching (tempering, annealing), which is a treatment method to achieve the expected performance by heating and cooling materials or parts in a vacuum according to the process specification.

3. Vacuum continuous casting machine. Melting and casting integrated design, various shapes of metal, like bar, strip, sheet, rod directly can be cast with our vacuum continuous casting machine.

4: Vacuum powder making machine is used to melt metal in a vacuum condition, and then break the molten metal into extremely fine particles by high-pressure water gun. It is widely used in the gold refirney  industry and metal powder industry.

5: Vacuum granulator, adopting the principle of induction heating, drill some hole at the bottom of the graphite crucible. The molten metal flows out through the hole at the bottom of the crucible and falls into the water tank to form uniform metal particles as per required.

Vacuum furnace has many different specifications and models and functions, and they are different in effective area size, furnace loading, heating power, etc., so welcome to inquiry us for more details.

Precious Metal Vacuum casting machine is designed for those ingot casting of gold, silve or other precious metal on basis of the customized mould. In the process of metal heating, The machine can vacumm pumping or inert gas inflate to make the gold or silver ingot surface looks more bright and smoothy, and without any oxidized or other loss.
Approaching each project as a partnership, the goal of COOLDO is to share the customer’s vision to produce the best for the your application.

High Pressured Vauum Queching Furnace is mainly used for cool work & hot work steel, high speed steel, tool steel material vacuum quenching, tempering and solution-ageing process. And it is divided into horizontal and vertical types. The vertical type vacuum gas quenching furnace is especially suitable for the vacuum gas quenching process of large workpieces with easy deformation such as long rod-shaped parts, shafts and plate parts. The workpieces can keep bright and minimal deformation after heat treatment.

COOLDO Vacuum Induction melting furnace is one of the most commonly used heating process in matel refining and adjustment of chemical compostion to achieve the quality demands. for example, Vacuum melting furnce is indispensable in the produce of special alloys, which must be melted under the vacuum or in an inert gas atmosphere because of their reactivity with atmospheric oxygen. This process is very suitable for the production of high-purity metal within an Oxygen-free atmosphere.
