Vacuum casting is the same as duplication using a silicone mold. Plastic vacuum casting using silicone molds was developed in the 1960s in German universities.
Vacuum casting is a casting process for elastomers using a vacuum to draw the liquid material into the mold. Vacuum casting is ideal when highly accurate,functional plastic prototype parts in very fine details are required.
This process is used when air entrapment is a problem, there are intricate details or undercuts,or if the material is fiber or wire reinforced.
If you are wondering which is the most economical way to make any prototype? Then you should try silicone vacuum casting. In vacuum casting, you’re require to have the correct optimum temperatures when curing the materials.
The process is sometimes called thermoforming because the manufacturing process involves rapid prototyping where the plastic sheets are preheated.
The materials are preheated in an automated silicone vacuum casting machine until they are soft and pliable.Vacuum casting is a copying technique used for the production of small series of functional plastic parts.
Using two-component polyurethanes and silicone molds,Vacuum casting is known for its fast production of high-quality prototypes or end-use products.
Silicone molding results in high-quality parts comparable to injection-molded components.This makes vacuum casted models especially suitable for fit and function testing,marketing purposes or a series of final parts in limited quantities.
Vacuum casting also lends itself well to a variety of finishing degrees, and we can match the finish you need for your parts.
High quality surface finish comparable to injection molding.Vacuum casting is used for producing small numbers pf highly accurate polyurethane prototype parts with characteristics and quality comparable to the final product.
At prototype projects we can produce parts to extremely fine levels of details and keep concessions to the absolute minimum.
The vacuum casting process begins with the creation of a master pattern using the Sterelithography process. The SLA model is then finished/painted to meet customer specified surface texture is achieved.
The small numbers of parts are made from a single master mold,which is made using an SLA master model usually using silicone rubber.
