Additives and Fillers: Colorants, metal powders, and fibers to enhance aesthetics, stiffness, conductivity, or wear resistance, giving engineering teams more control over part behavior in real conditions.
How Costing Works
The cost of silicone casting services depends on mold complexity, material selection, finishing requirements, and production volume. For rapid manufacturing and silicone casting for prototyping, NEXAMS keeps costs practical by minimizing tooling expenses and leveraging vacuum casting to improve yield; for medium-volume silicone casting batch production, smart kitting and repeatable mold cycles reduce per-unit cost while keeping schedules predictable.
