What Are Spray Molds?
Precise Temperature-Controlled Molds for Robotic PU Spray
Spray molds are specifically designed tools used in robotic or manual spray polyurethane (PU) processes to create soft-touch, durable interior skin components. Weber’s spray molds employ Nickel Vapor Deposition (NVD) nickel shells with built-in temperature control for superior consistency and surface fidelity. These tools are ideal for instrument panels, door panels, and armrests—especially in two-tone or multi-material applications.
Cleaner, Faster Tooling—Optimized for Your Interior Programs
- Rapid lead times: Weber delivers spray molds in just 18 weeks for instrument panels, with consecutive tool delivery every three weeks for large-scale programs
- Industry-grade NVD shells: Reusable deposition mandrels produce multiple nickel shells quickly and cost-effectively, maintaining dimensional precision across tool sets webermfg.ca+1webermfg.ca+1.
- Deep-under-cut capability: Designed for complex part geometries, Weber’s nickel shells can accommodate tight radii and undercuts commonly found in automotive interiors
Key Features & Benefits
- Rapid, repeatable cycle times thanks to wheel-mounted infrared or air heating and uniform temperature control
- High fidelity surface reproduction and sharp detail via NVD nickel shells
- Scalable tooling: one master model and reusable mandrel can produce multiple shells—enabling low-cost, fast delivery, and minimal variation
- Full-service supply: NVD shells, slush powder tubs, powder boxes, and carrier frames—delivered ready for production
Supporting Two-Color & Multi-Material Applications
Weber manufactures spray masks and tooling frames optimized for two-tone PU spraying. This enables precise material separation and consistent part differentiation during robotic or manual spray cycles
