  • Vacuum Casting for Flexible and Economic Production

    product-description1e62

    Urethane or vacuum casting merges silicone molds with a 3D printed master pattern to produce high-quality, rigid parts in limited quantities. The procedure solidifies thermoplastic polyurethane within silicon or epoxy molds, yielding parts that mirror the shapes of the original master models. The ultimate dimensions of these parts are contingent upon the master model, part geometry, and chosen material.
    Breton Precision, a top vacuum molding maker, provides economical production of top-notch plastic components. This method removes the necessity for costly initial capital. Our vacuum casting solutions provide the full answer for crafting top-grade prototypes and small-batch production parts.
