Brightstar's standardized operating procedures ensure accurate replication of parts and consistent mechanical properties. Our vacuum casting technicians control all operational parameters:

The casting mold is made from liquid silicone resin, also known as RTV mold. The silicone rubber has excellent chemical stability, self-release properties, and flexibility, and because it has minimal shrinkage, it can effectively transfer fine details from the master model to the mold.

The quality of the cast polyvacuum parts depends on the quality of the master model. When you need to maintain strict tolerances, glossiness, or even optical clarity, it is best to process through CNC machining.

CNC milling is a machining process to remove material and shape the workpiece. Brightstar has over 100 milling machines for rapid prototyping and custom machining of metal and plastic parts.

Overmolding uses injection molding to create parts made from multiple materials.

Metal injection molding typically refers to the process of mixing metal powders with plastic resins, melting them at high temperatures, and then injecting them into molds to form metal-reinforced plastic parts.

Liquid Silicone Rubber (LSR) is an inert and biocompatible material, ideal for manufacturing medical injection parts such as fluid management, respiratory equipment, and more.

Injection molding is a custom plastic parts manufacturing process that involves injecting high-pressure thermoplastic into molds.

Essential for mass production, including the manufacture and assembly of durable molds using steel or aluminum to ensure precise and repeatable part geometries.
