Technical Plastic Ducts

Plastic Ducts for Turbo Air Circuits

MANUPLAST designs and manufactures technical plastic ducts for turbocharger intake and outlet air circuits serving the automotive, agricultural, construction (off‑road), and industrial sectors.

Installed at the heart of the under‑hood environment, these components are subjected to particularly severe constraints:

  • air intake scoops
  • high temperatures
  • rapid thermal variations
  • boosted air pressure
  • engine vibrations
  • exposure to oil mist

Design of plastic extrusion parts suitable for extreme environments

Nos conduits en plastique sont réalisés à partir de matières techniques haute performance (PA, PA chargé, PP, EPDM, TPC) sélectionnées pour garantir :

Our plastic ducts are manufactured from high‑performance technical materials (PA, reinforced PA, PP, EPDM, TPC), selected to ensure:

  • high thermal resistance
  • resistance to turbo pressure and pressure pulses
  • excellent resistance to oils and condensates
  • controlled flexibility and vibration absorption
  • long‑term dimensional stability

Grâce à la technologie d’aspiration 3D, nous obtenons des géométries complexes optimisées pour le passage des flux d’air, tout en maîtrisant poids et encombrement.

Thanks to 3D suction technology, we are able to produce complex geometries optimized for airflow, while maintaining strict control over weight and space requirements.

With more than 65 years of expertise in 2D extrusion blow molding, MANUPLAST masters the production of hollow plastic components in a wide variety of shapes. Parts can then be cut, machined, welded, or assembled to deliver a complete, ready to‑install solutions.

Plastic components for battery cooling systems

Dans la continuité de notre expertise en conduits techniques, MANUPLAST développe également des conduits plastiques dédiés aux systèmes de refroidissement de batteries, pour les applications véhicules électriques (VE), hybrides, stockage d’énergie et équipements industriels haute performance. Building on its expertise in technical ducting, MANUPLAST also develops hybrid vehicles, energy storage systems, and high‑performance industrial equipment.

Ducts Designed for Battery Thermal Management

Temperature control is critical to ensuring battery durability, safety, and performance. Our plastics ducts are designed to provide:
