Vacuum casting
What is the vacuum casting?
Vacuum Casting is a rapid prototyping technique used to manufacture complex parts. It combines traditional casting processes with modern vacuum technology. This technique is commonly employed for small-batch production and rapid prototyping, especially when high quality, precision, and surface finish are required.
The process of vacuum casting typically involves the following steps
Firstly, a mold for casting is created based on the design of the desired part. This mold is usually made from materials such as silicone or polyurethane and replicates the shape and details of the final product.
The mold is placed inside a Vacuum Casting machine and properly positioned and sealed. The mold should be hollow to allow for material injection.
The selected material, often a two-part liquid epoxy resin, is injected into the mold using the control system of the Vacuum Casting machine. During the injection process, the vacuum system removes the air from the mold to ensure density and quality of the part.
After the material is injected, the mold is placed in a controlled environment for curing and cooling. This process typically requires a certain amount of time to ensure complete solidification and hardening of the material.
Once the material is fully cured, the mold is opened, and the part is removed. Necessary post-processing steps such as trimming, grinding, painting, etc., are performed to obtain the final product.
