The choice between the two methods depends on budget, production volume, and product complexity. Vacuum casting is better suited for producing small quantities of complex parts with fine details, while injection molding is ideal for large production runs of simple parts.
Centrifugal casting involves pouring molten metal or plastic into a spinning mold, which uses centrifugal force to distribute the material evenly throughout the mold. Vacuum casting is better suited for smaller and more intricate parts, while centrifugal casting is better suited for larger and simpler parts.
we can provide design assistance, tooling fabrication, and production services as well as post-processing and finishing operations. Additionally, we will work with you on material selection and help ensure that quality standards are met throughout the entire process.
