EV Powertrain Housing

Saint Jean Industries is able to offer complete solutions for the design, manufacture, heat treatment and pre-machining of complex aluminium core parts such as electric motor housings.

Types of products: electric motor housing with or without cooling circuit, power electronics housing

Engine mounts

These mounts hold the engine in place and are sometimes subject to significant mechanical and vibrational strains. Saint Jean Industries designs and manufactures this type of mount from cast iron, steel and aluminum.

Manufacturing processes: shell molding (Croning) cast iron casting, gravity die casting, machining and assembly.

Types of products: Engine mount, battery mount, drive shaft bearing.

Rotor and stator for retarders

Retarders are placed in the gear boxes of buses and heavy trucks. These parts are subject to high mechanical strains, with very slender areas of less than 1 mm, and require an excellent surface condition.

Manufacturing processes: steel shell mold casting (Croning).

Types of products: speed governor rotors and stators.

Intake parts

Intake parts are used to provide air to each combustion chamber to allow the engine to function correctly. Saint Jean Industries specializes in the design and manufacture of this type of aluminum part.

Manufacturing processes: gravity die casting with sand cores (hot or cold box), machining and assembly.

Types of products: intake shims, intake pipes, distributors, piping, etc.

Turbocompressors

Saint Jean Industries specializes in the design and manufacture of parts and sub-assemblies for turbocompressors.

Mass-production processes:

  • Gravity die casting
  • Low-pressure casting
  • Cast iron and steel casting using shell molding
  • Machining and assembly

Prototype manufacturing processes:

  • Billet machining.
  • Aluminum casting by sand molding or 3D printing.
  • Cast iron or steel casting by sand molding or 3D printing.

Types of products: turbine casings, turbo manifolds, compressor casings, central casings, e-turbo, compressor wheels, valves, backplates, etc.

Exhaust manifold

Manifolds are designed to vent exhaust gases from the engine, often at very high temperatures (850 to 1,050°C), hence the need to manufacture them from steel and obtain the best surface condition to ensure good gas flow.

Manufacturing processes: steel shell mold casting (Croning), machining.

Types of products: Exhaust manifolds, turbo manifolds.
