Vacuum Casting is a Specialized Manufacturing Technique
Vacuum casting , also known as resin casting or polyurethane casting, is a manufacturing process used to create small series of high-quality plastic or rubber parts. It's particularly useful for producing prototypes, functional models, and low-volume production runs where the cost of injection molding would be prohibitive. Process Overview: Master Pattern Preparation : A master pattern of the desired part is created using methods like 3D printing, CNC machining, or handcrafted models. This master pattern must be precise and typically made from materials like wax, plastic, or metal. Mold Creation : A silicone mold is made around the master pattern. Silicone is chosen for its flexibility, durability, and ability to capture intricate details from the master pattern. The mold is typically created in two halves to allow for easy removal of the pattern. Vacuum Casting Process : Mold Preparation : The silicone mold halves are se...
