Vacuum casting/ Urethane Casting offers an economical solution for small batch production of plastic parts. By using silicone rubber molds and CNC or SLA parts as the main mold, we can accurately replicate details and textures, ensuring consistent finishes from one part to the next. This process allows us to simulate the final molded part or finished product, providing a cost-effective alternative to injection molding.

Product Operate Guide
1. Prepare the Master Model: Create a high-quality master model using 3D printing or CNC machining techniques.
2.Mold Making: Build a silicone mold around the master model, ensuring it captures all the intricate details.
3.Mixing and Pouring: Prepare the PA casting material by mixing the resin with a hardener. Degas the mixture to remove air bubbles. Pour it into the mold.
4.Vacuum and Curing: Place the mold in a vacuum chamber to remove air bubbles. Cure the PA material in an oven or under UV light according to the specified temperature and time.
5.Demolding: Carefully remove the mold to reveal the casted part. Trim any excess material and perform post-processing if required.
6.Quality Control: Inspect the casted part for dimensional accuracy, surface finish, and any defects. Ensure it meets the desired specifications and quality standards.
7.By following these technical parameters and operating guidelines, vacuum casting provides a reliable and efficient method for producing high-quality prototypes and small-batch production parts in various industries.
