    We have produced highly porous sintered materials at our site in Dortmund since 1953. Our many years of varied experience in the processing of PE, stainless steel and bronze to highly porous plates, pipes, moulded parts and customised welded constructions makes us a competent partner in the search for the best solution for your specific application problem. Typical applications of our materials include: Bulk material handling, gasing/degasing, filtration, silencing, safety technology, capillary transport, engineering. Testing bulk material qualities for fluidisation. Selecting the optimal material. Collaboration to find system solutions. Quality assurance. Bubble-point permeability test, electronically controlled measuring of system pressure, differential pressure, flow, flow rate. Porometer measurements. Determination of the degree of separation for filters by independent institutes. Determination of tensile strength and shear strength. Customised measurements. We are certified in line with DIN and ISO
