IMAL, a specialist in machinery for the production of wood particle, plywood, MDF, OSB, has created a quality control system to be placed at the end of the production cycle, based on TeraHertz / millimeter wave (T-ray) technology. They turned to CRP Technology for the manufacturing of their functional sensor housing box, as they didn’t want to use mass-production to do it, as it would not have met their quality criteria.

The application had to be created in a short time, and to combine high mechanical characteristics (resistance to acceleration, stress and heat) whilst maintaining high level aesthetic standards.

How does it work?
Work began with an accurate analysis of the 3D and 2D files. CRP Technology then selects the Laser Sintering process and Carbon-composite Windform XT 2.0 material, from the Windform top-line family of composite materials for LS technology (invented by CRP Technology itself). The choice of the material proved to be particularly appropriate: the sensor housing box turned out to be electromagnetically shielded thanks to the Carbon filled Windform XT 2.0 composite material. An added unexpected bonus considered very important by IMAL.

Once received the .STP file from the client, CRP Technology created the functional 3D printed sensor housing box in two shells. To obtain higher feature tolerances, the sensor housing box has been CNC-machined on a 5-axis machining center on specialized jigging, via Subtractive technology. This was possible through the characteristics of Windform composite materials.

A laser scan was performed on the finished part, from which a control report was drawn up to be provided to IMAL.
