Gravity die casting (GDC) & Low pressure die casting (LPDC or LPPM)

Aluminium casting is the historical core business of Saint Jean Industries. Whether gravity or low-pressure casting, these two technologies are available at the majority of the group’s sites.

Aluminium GDC and LPDC technologies are used for many years in the car industry in order to save weight and cost. These technologies enable the production of parts with:

  • complex shapes, hollow if necessary via the use of sand cores
  • average mechanical properties: Rm = 290 Mpa, Rp0,2 = 210 Mpa, A% = 6%

All our casting tooling are designed and manufactured in-house, ensuring we are extremely responsive to your needs.

This is the first stage of the COBAPRESS™ process, which obtains a preform before the forging operation.

Gravity die casting: Our light, flexible and automated equipment delivers high production rates ranging from a few thousand to several million parts per item.

Low-pressure die casting: These facilities deliver high production rates with the use of multi-die molds through a central supply unit.

Typical parts manufactured

GDC and LPDC / LPPM are particularly suitable for safety critical parts such as suspension and chassis parts: knuckles and wheels carriers, hollow knucklescontrol arms, hollow control armssuspension bracket, transmission holders, subframe nodes, cradle
