Vacuum Casting Materials
ABS (Acrylonitrile-Butadiene-Styrene)
ABS is one of the most popular materials for Vacuum Casting Services because it offers a strong balance of toughness, rigidity, and good surface finish. It is especially suitable for functional prototypes and small-batch production where parts need to replicate the performance of injection-molded plastics. Vacuum-cast ABS parts are often used in automotive components, electronic housings, and household appliance prototypes. For example, dashboards, connectors, and consumer electronics shells can be cast in ABS to verify both mechanical performance and aesthetic requirements before moving to large-scale injection molding.
