Composite

LAUAK Group has skills in composite sector in both thermosetting materials and RTM technologies.

 

CENTRAIR company proposes its know-how in the following areas:

 

  • floor panel
  • structure parts
  • tubes and pipes
  • electric boxes

 

The main means of production are ovens, presses, autoclaves (up to 8m long and 3m diameter) and 5-axis CNC machining.

Hard Metal Sheet Metal, Hot Forming

LAUAK Group invested into two Hot Forming and Super Plastic Forming industrial machines (with a maximum strength of 800 T). Those both technologies allow to manufacture complex parts of shape in titanium with very high mechanical performances for an optimized final part mass.

 

  • Hot Forming: In heating platens press, deformation by tooling punch / matrix maintained at temperature (600 to 800 °C) compatible with elongations up to 50%.

  • Super Plastic Forming: On matrices made of refractory alloy, 900°C stamping by “gaseous punch” (Argon inert gas) to form the metal and allow extreme elongations (up to 500%).

Tubes and Pipes

LAUAK Group created a 700 m² Autonomous Production Unit (APU) dedicated to piping with the following technologies:

• Tube bending

• Welding

• Crimping

• Pressure tests 

• CND (penetrant testing, radio)
