Why Choose UNION for Your PVC Foam Machining Needs?

  • One-Stop Closed-Loop Production


    We control the entire process—from raw material formulation and foaming to CNC machining and finishing. This allows us to adjust material density, rigidity, and cell structure to optimize machinability and final part performance.

  • Reduced Resin Consumption & Assembly Time


    Our precision CNC-machined custom PVC foam parts are designed to fit perfectly within composite structures, significantly reducing resin usage during infusion or lamination processes. By providing near-net-shape components with tight tolerances (±0.2mm), we minimize gap filling and material waste. This leads to direct cost savings for you—especially important given the high cost of resins—and shortens installation time thanks to simplified assembly and reduced manual adjustments.

  • Cost & Time Efficiency


    By eliminating middlemen and reducing logistics, we offer faster lead times and 20–30% lower cost compared to outsourced machining solutions. Full production cycles are streamlined under one certified ISO facility.

  • Expert Technical Team


    Our engineers and machinists have extensive experience in interpreting 2D drawings and 3D models with minimal back-and-forth. We ensure design intent is accurately translated into machined parts with tight tolerances (±0.2mm) and superior surface quality.

  • No MOQ & Free Samples


    We support both prototype and production orders—no minimum order quantity. Request free A4-sized samples to validate fit, finish, and performance.

  • Full Customization Support


    · Multiple surface treatments: grooved, perforated, scrim-backed, hyperbolic.
    · Wide thickness range: 2mm–70mm (±0.2mm tolerance).
    · DNV GL-certified foam grades: P45 to P250 densities.
    · Secondary processing: bonding, laminating, edge-sealing.
