Polyurethane Overmolding Molds

Riamolde designs and manufactures polyurethane overmolding molds from simple tooling to complex serial-production solutions, including full-harness overmolding applications.

Our mold engineering is developed around the customer’s part, PUR process, workstation and production requirements, allowing tooling and production equipment to be engineered as one integrated system.

Prototype and serial-production overmolding molds

• Prototype molds: delivery timing is defined according to project complexity and validation scope.
  • Developed to support validation before the serial-production mold.
  • Simplified configuration with the level of automation required for development and validation.
  • Typically manufactured in aluminium.
  • Can be supplied with a supporting mold console.
• Serial-production molds: delivery timing is defined according to project complexity, automation and validation requirements.
  • Engineered for automated serial-production applications.
  • Can be mounted on a Riamolde console structure with dedicated controls.

For demanding applications such as automotive wiring harnesses, tooling design is considered together with part positioning, PUR processing, production handling and the required automation level.
