Vacuum Casting Manufacturing To Low-volume Production Choice
As one professional CNC machining manufacturer, Creatingway always offer customers different machining method according to customers’ project quantity, budget, and delivery date request. Here vacuum casting is one of the ways we provide for plastic parts projects.
What is Vacuum Casting Manufacturing?
Silicon Molding also named Vacuum Casting. It is a kind of rapid tooling manufacturing technology (RT), appeared by the development of rapid prototyping technology and new materials development, and silicone mold is one of the ways most widely used in making a prototype for low volume manufacturing of plastic and rubber parts. Using silicon mold instead of a steel mold, the cost will be reduced a lot. When customers only want one or two for their design, this process is suitable. And for trial production and low volume production, too. Here Creatingway may show you some more information about vacuum casting.
Material choice for vacuum casting manufacturing
ABS, PP, PC, PMMA, POM, Nylon (PA), heat-resisting material, polyethylene, silicone rubber, and so on. Most plastics material is suitable to vacuum casting manufacturing. Specifically, some of the automotive lightings asked our product is very transparent, so Vacuum casting will be the best choice for us.
Advantages of vacuum casting manufacturing.
By vacuum casting, you can work out those complex parts with different shapes in which CNC machining has limited, and this production time is fast, most important is the less cost and processing failure rate is very small. Also, one silicone mold can cast about 10-25 pieces or dozens of pieces of the same products. Also, the cost of vacuum casting manufacturing is lower than our current CNC machining, and rapid tooling, etc process.
What’s the Vacuum casting manufacturing process?
- Make Prototype: According to the 3D drawings provided by the customer, the prototype is made by CNC processing, SLA laser rapid prototyping, or 3D printing.
- Cast silicon mold：Once finished make the prototype, make mold frame, fix the prototype, pouring silicon. After 8 hours of drying, take out the prototype from mold and the silicone mold is finished.
- Vacuum Casting Manufacturing：To inject liquid rubber materials into a silicone mold, curing about 30 to 60 minutes under the constant temperature box of 60-70°, and then release it. If necessary secondary curing for 2-3 hours in the constant temperature box of 70-80°.
- Generally, silicone mold service life is normally 15 to 20 times.
