Custom Vacuum Casting Service
Goodtech’s Vacuum Casting service delivers high-quality plastic parts for rapid prototyping and small-batch production. Using silicone molds and polyurethane resins, we create parts with exceptional detail, smooth surfaces, and properties akin to injection-molded components, ideal for testing and market validation.
What is Vacuum Casting?
Vacuum casting is a process used for producing small-volume, high-quality plastic parts, prototypes, and functional models. It involves creating a silicone mold from a master pattern, then using the mold to produce a limited number of cast resin parts..
Vacuum casting is a versatile process that can produce parts with high levels of detail and a smooth surface finish. It is commonly used for producing prototypes, small production runs, and functional models, where a high degree of accuracy and surface finish is required. Additionally, vacuum casting is relatively fast and cost-effective compared to other manufacturing processes, making it a popular choice for producing small-volume parts.
The Vacuum Casting Process
Master Model Creation: A high-precision master model is crafted, typically via 3D printing or CNC machining, to ensure accurate replication.
Silicone Mold Production: Liquid silicone is poured around the master model and cured to form a flexible, reusable mold.
Resin Casting: Polyurethane resin is mixed, degassed, and poured into the mold under vacuum to eliminate air entrapment.
Curing and Demolding: The resin cures in the mold, and the part is removed, ready for finishing or assembly.
What are the advantages of Vacuum Casting?
- High Quality: Vacuum casting produces parts with a high level of detail, a smooth surface finish, and dimensional accuracy. The use of a silicone mold and vacuum technology helps to eliminate entrapped air, resulting in a high-quality part.
- Versatility: Vacuum casting is capable of producing parts in a wide range of materials, including polyurethane (PU), epoxy, and polypropylene (PP), making it a versatile manufacturing process.
- Cost-effectiveness: Vacuum casting is a cost-effective process compared to other low-volume manufacturing methods, such as injection molding. This is because vacuum casting does not require the investment in a complex and expensive mold, as is required for injection molding.
- Flexibility: Vacuum casting is a flexible process that can be used to produce parts in a variety of shapes and sizes, making it suitable for a wide range of applications.
- Low-volume production: Vacuum casting is ideal for producing small-volume parts, prototypes, and functional models, where a high level of detail and surface finish is required.
