Vacuum casting or silicone molding is a very good choice for plastic rapid prototype, when the quantity is about 20 pieces or less. Vacuum casting is a clone processing which using the original sample to make a silicone mould in vacuum state, and injecting PU material to the mould in vacuum state, then a copy will be cloned out.
What is Rapid Prototyping?
Rapid prototyping is the fast fabrication of a physical part, model or assembly using 3D computer aided design (CAD). The creation of the part, model or assembly is usually completed using additive manufacturing, or more commonly known as 3D printing.
How Does Rapid Prototyping Work?
Rapid prototyping (RP) includes a variety of manufacturing technologies, although most utilise layered additive manufacturing. However, other technologies used for RP include high-speed machining, casting, moulding and extruding.
While additive manufacturing is the most common rapid prototyping process, other more conventional processes can also be used to create prototypes.
