The main focus of the Pernoud Group in North America is to provide premium plastic injection molds, improving mold processes and productivity.

Our primary customers are the Original Equipment Manufacturers and Tier 1 suppliers in the automotive industry who manufacture under hood parts for air and fluid transfer systems.

With our tooling, we can develop innovative technologies such as our patented Multitube molds and Multi-Process molding (MPM).

Georges Pernoud R&D allows us to offer solutions for improving upon existing molding processes:

  • Co-design of plastic parts
  • Cross-functional integration from metal to plastic
  • Conformal cooling of the tool by laser sintering

The Multitube®, an Innovative Technology :

  • By eliminating post molding operations such as welding on plastic parts
  • Validated according to the automotive specifications
  • Series production programs on Ford, Fiat, Mercedes and Audi
  • By using standard resin, injection molding machines, end of arm tool
  • Developed as part of the productivity and cost savings
  • By allowing an investment pay-back less than 1 year
  • Improved internal quality (reject, cleanliness, tightness)
  • Removal of in-progress and simplified management of spare parts
  • Appropriate for typical functions Air duct , Water duct, Turbo duct, Air Filter, Air Intake Manifold
