Vacuum Casting
Vacuum Casting
ABC Rapid has fully capabilities to handle your vacuum casting and silicone molding demands. With years of expertise in this field, we’re able to manufacture your plastic parts with high quality standard and competitive price.
Vacuum casting (also know as urethane casting) is a widely used process in rapid prototyping, typically used for building 10 to 50 pieces of functional prototypes out of broad range of polyurethanes and other polymers.
How Does Vacuum Casting Work?
Generally, using CNC machining or SLA part as a master pattern first, and then create a mold which made from silicone material. The mold duplicate intricate details and textures from the master pattern. Then pour liquid casting material under precise vacuum into the mold, take the copy parts out of the mold and remove excess materials, finally get fine texture and colored parts one by one.
Advantages of Vacuum Casting
1. Fast turnaround: Only need about 2 weeks or less to make the parts well
2. Economical in both cost and time: Silicone molds are less expensive than metal tools, but more easier and faster to make.
3. Surface finish options: Different Colors, Textures & Finishes Available
4.. Repeatability: Silicone molds can be used around 20 times before replacing.
5. Excellent Physical Properties: The casting parts have good Physical Properties for functional purpose.
The Capability of Vacuum Casting
We can accurately reproduce the prototypes with original color, over-mold, texture and geometries from the master model and components. These plastic castings will closely represent the mechanical properties of the intended production parts from a steel mold. One silicone mold can cast about 15 to 20 pieces of parts, depends on complexity, painting or original color, size and other factors in different parts. The typical lead time is 7 working days for 10 parts.
