Rapid injection molding
From Plastics Wiki, free encyclopedia
Rapid Injection Molding allows us to make prototype injection molded parts in a production thermoplastic resin in 2-5 weeks. These parts may be used for full functional and fit testing as well as test marketing. Using Molding process, cast the tools from patterns fabricated from rapid prototyping or CNC machining. Also called Prototype or Short-Run Injection Molding
Cast tools are made directly from the designer's database using stereolithography (SLA) or CNC machined masters. In our aluminum foundry, we cast the injection mold. Perfect for prototypes, this process is also an excellent short run or bridge-to-production method, since these molds can produce thousands of parts.
Advantages
- Prototypes in production thermoplastic resins in 2-5 weeks
- Bridge or production tooling - molds can run 1000’s of parts
- Most colors and materials available
- Molds can be textured
Disadvanages
- Size Limitations is approximately 7.5 inches by 14 inches
