Turnkey projects

We design, build and install complete lines and sub-systems. From mechanical engineering to electrical cabinets and PLC programming.

Services
Engineering + distribution

We represent brands. And build our own.

We are an official Graco Adhesives distributor and resell compatible parts for every major hot melt system on the market. In parallel, we design in SolidWorks and Fusion 360 and machine on our own CNCs in Portugal a proprietary line of applicators and modules under the Rapson brand.

Environmental commitment

Regeneration is the greenest way to manufacture.

Every regenerated part is a new part that does not have to be manufactured on another continent, packaged and shipped to Portugal. Our footprint is smaller because our logic is circular.

Every part we regenerate is a new part that does not have to be manufactured and shipped from Germany, Switzerland or the United States. It is a direction we are still learning to measure properly — but it is where we want to get to.
