Are you looking for the pros and cons of casting machine? What’s so special about this machine? What are its specifications? Just to gain solutions to all the questions, you can refer to this article.

Vacuum Casting Machines

Basically, Vacuum casting is the process of forcing the metal into the mold just to produce dense, thin-wall and high- quality castings. Vacuum casting is also thermoforming and it’s usually used when there is an air entrapment problem. Also, this machine is used when the material is wire or fiber reinforced.

Now, let’s see the features, advantages and specifications of this machine. This machine utilizes plastic sheet goods just to process it into a mold.

Why to Buy this Machine?

Vacuum Casting Machines are mainly needed to suck the metal into the mold. These machines make your process easier and major advantage is that you don’t need to follow the tedious balancing procedure.

It offers with more reliability and it’s highly durable too. It is mainly used to resolve issues caused due to air entrapment. The machine comprises of melting furnace, vacuum investing and casting.

What are its Features?

It is capable of molding up to 520mm x 445mm x 425mm.

The voltage of the machine is about 230v with the current supply of 8-10 amps.

Oil capacity is around 3-3.5 ltrs. It is also designed with the automatic self-vibrating investment table and possesses heavy-duty construction.

It possesses tow tank system just to generate high vacuum pressure for less porosity casting.

It’s capable of accommodating flask with the size of 2”to 5”Dia and height of about 9”. It’s approximately 110kg weight.

Pros and Cons of Vacuum Casting Machine

  • Vacuum casting machine is capable of creating larger parts mold. The mold size may range up to 48” x 96”.
