Vacuum casting and benefits it encompass

Wondering to make a prototype under your budget? Here is the suggestion that meets your budget as well as meets your expectation in creating a prototype.

Then vacuum casting is the ideal of option for fit and function testing, marketing purpose. Low volume production runs of plastic parts can also be manufactured using vacuum casting. Since it is versatile process, numerous industries are getting benefited by sourcing it.

What is Vacuum Casting?

It is generally a casting process for elastomers. Employing vacuum to draw any liquid material into the mold, casting is done in this method. Vacuum casting is ideal to use when air entrapment is a snag in the mold, intricate details and undercuts on the mold etc. This process is also called as thermoforming as its manufacturing process encompass rapid prototyping somewhere the plastic sheets are preheated in the process.

How Vacuum Casting Works?

The working procedures of vacuum casting are listed below.

High Quality Master Model

Vacuum casting process needs high caliber master model which is also an industrial part.  Model created after stereo-lithography process if you are sourcing prototyping application.

The master model should possess no flaws and opt right dimension as well as looks. 

Cure Process

When the master model is done, it is condensed into two fragments of silicone rubber mold. To make sure the two parts stick together, it is cured under high temperature. Curing process strengthens the mold and ensures its durability.

Cured mold is sliced at the center to reveal hollow space which possess the precise measurement of master model.  The mold is then placed into vacuum chamber for further filling of designated material to bring out the product.

Fill The Resin

When the mold is filled with desired material in vacuum chamber, the resins duplicates the features of industrial material. To achieve the desired outlook or to hike the aesthetics of the outcome, the resin is mixed with metallic powder or other coloring agent.

Final Cured Process

The resin is then placed in the oven for its final stage of curing process. It is cured in high temperature for strong and durable process. Now the silicone mold is removed to make more prototypes.

The removed prototype from the mold is painted or maneuvered to bring out the final look. It is mainly depending on the desire of manufacturer.

This is how prototypes are made from vacuum casting method.

Benefits of Vacuum casting:

Vacuum casting possess various benefits and some of the prominent are listed as follows.

High precision and fine detail to the finished product

High quality of the product

Lowers production cost

Increase productivity

Consumes short span of time to bring out the effectual results

Adopt this manufacturing process if you are up to fabricate prototype or low volume plastic products.

I hope this article enlightens you the vacuum casting process and the benefits it encompasses to the manufacturing industry. Opt this manufacturing process and rely on the advancements it encompasses.
