ENGINEERING

Research and development are very important at New Lachaussée.

 

Upstream the machine design, engineering at New Lachaussée involves research on strength of materials, physical and chemical properties of metals and alloys, and constant analysis of client feedback.

Cold forming simulations

Using state-of-the-art software, our mechanical designers simulate the operation of the tool during a press cycle, for detailed analysis of the metal deformation and temperature variation.

Among others, they calculate the forces required for the press and tooling. They also design the right chilling circuits.

Metallography

Using fine metallography techniques, our engineers analyze the grain size of metals and alloys, as well as the distribution of particles. This helps in the definition and verification of annealing processes and subsequent treatments.

A sample of cases is reserved for quality inspection. Specimens are prepared (polished and etched) to be examined with a microscope.

Micro-structure of a case, seen under a LEM microscope with a magnification of 200x. The grains are smaller and tight at the periphery, which weakens the surface. Proper treatment is pickling.

Presses for any metal element

New Lachaussée welcomes the challenge.


Relying on the large experience of our design office, we also engineer high-output presses, of all sizes, to produce all kinds of elements other than ammunition or detonators: lipstick cases, lighter heads, rivets, airbag parts...
