Vacuum Casting: We provides Vacuum Casting as a major prototype tooling option in Polyurethane's, which resemble properties equivalent to PP, ABS, elastomers, and transparent. Silicone rubber molds have excellent chemical resistance, low shrinkage and high dimensional stability, making them suitable for producing parts in polyurethane by injection molding. Initially, a silicone rubber mold is made using the master sample obtained from rapid prototyping or readymade masters supplied by the customer.
Liquid Silicon rubber is cast around a Rapid Prototyping master (preferably SLA).After curing the Silicon block is cut open to form the core and cavity after the master removal.
Why we vacuum casted parts? - Functional plastic parts. - Wide range of polyurethane resins from elastomers to 30 percent GF Nylon - Various kinds of inserts possible - Different colours / shades possible
