Vacuum casting is a casting process for elastomers using a vacuum to draw the liquid material into the mold. This process is used when air entrapment is a problem, there are intricate details or undercuts, of if the material is fiber or wire reinforced.
Vacuum casting is a low-cost but reliable method for making a small number of high-quality prototypes based on a master model.
The tolerance of vacuum cast parts is dependent on the accuracy of the master model, part geometr and casting material. Generally, ashrinkage rate of 0.15% is normal.

Advantages Of Vacuum Casting

	Vacuum casting is an ideal choice for rapid prototyping because:
	There is a low initial cost since it doesn't require investment in tooling
	The high fidelity of the mold gives excellent surface details requiring little or no post-process
	Many different molding polymers are available that can be pigmented to meet your color requirements
	Molds can be read in a rew days once the master model has been created
	Molds are durable up to approximately 50 copies so it's great if you need more than one copy
	We provide overmoling, so that different types and hardnesses of plastic can be molded together into a single unit
	It is an excellent option for testing multiple variations of a prototype design for rapid product development

The Vacuum Casting material

The Vacuum Casting material include ABS, PP, Acetal, Crystal Clear, Rigid PA POM, Rubber, High-Temp ABS, etc.

The application of the rapid prototyping device will be to merge rapid prototyping capabilities with the high-volume output of conventional manufacturing.
It is believed that the rapid manufacturing processes may soon lead to the tooless production of finished goods and the mass production of individually customized parts.

Rapid Tooling(RT) describes a process that is the result of combining Rapid Prototyping techniques with conventional tooling practices to produce a mold quickly or parts of a functional model from CAD data in less time and at a lower cost relative to traditional machining methods.
