PLANNING AND DEVELOPMENT
We design all our products with CAD-CAM-SCANNER systems, through prototyping and assembly and operation simulations for each component and for each finished product, with performance tests performed in independent laboratories.
This is why we’re the logical choice to produce quality products for OEM contracts and leading automakers.

         FILONG has advanced and reliable production technologies that allow us to create quality products and contain production times and costs to be competitive in an increasingly demanding market.
         A fundamental part of our production process is the constant control of every detail. We are equipped with in-line testing systems that verify 100% of the filters produced and we have a laboratory inside where checks are carried out on the incoming materials and functional tests on the finished products.
