Overview Powder Shaping Technologies FAST-Direct-Hot-Pressing / Granulating / Mixing POWDER SHAPING TECHNOLOGIES

Over 60 years of milestones in the sintering technology Since the foundation of the company over 60 years ago, Our customers are the center of our business – that is Dr. Fritsch has continuously been setting milestones in what nearly 100 employees in our German and Indian the sintering technology. Our self-developed FAST-Direct- companies as well as a global sales network with Hot-Pressing has triggered a little revolution in the representatives all over the world stand for. Our highly industry. Finally it was possible to significantly shorten qualified service technicians guarantee a comprehensive the sintering cycle. This not only lowered production and competent support on site. The close interdiscipli­ costs at higher productivity, but also allowed the nary cooperation of our construction teams allows the development of new materials and products with development of individual solutions and also complete considerably improved properties. production lines according to your requirements. The early beginnings of Dr. Fritsch started in the diamond In our Application Center we offer extensive test tool industry. In this sector Dr. Fritsch holds a market possibilities on nearly all machines from our product share of about 50 % and the FAST-Direct-Hot-Pressing range. Upon request, we also provide assistance in the has become a standard. Meanwhile many other indus­ field of mold design. Since we are exclusively focused on tries benefit from customized sintering solutions. Beside machine production without any final product manu­ the manufacturing of diamond tools, the Dr. Fritsch facturing you can always rely on our confidentiality sintering presses are also used for the production of regarding your R&D activities. brakes and clutches, heat sinks, sputter targets, in the hard metal industry as well as at universities and research Dr. Fritsch would like to contribute to your success with institutes. In addition to these innovative sintering experience, innovative technologies, highest quality and presses, Dr. Fritsch offers field-tested solutions for mixing first-class service. and granulation of metal and ceramic powders. We look forward to cooperating with you! Yours DR. FRITSCH team 2

Technology FAST stands for Field Assisted Sintering Technique. This refers to the heating of a mold by means of current flow. The unit is not heated from outside as usual in a furnace (indirect), but from inside (direct). Dr. Fritsch applies a self-developed direct current process (FAST-Direct-Hot-Pressing). This process can also be used with electrical non-conductors such as various ceramics. In this case heating occurs through the sintering mold and therefore much closer to the sinter part than with conventional heating technologies. This heating technology has significant advantages: ● The very short sintering cycles reduce the unit costs at a higher productivity ● The significant reduction of the grain growth improves the property of the material ● The attainable densities are considerably higher than with conventional sintering methods ● The temperature control is very precise due to the direct resistance heating ● The development time for new materials can be substantially shortened ● New material combinations can be manufactured, for example FGMs (Functionally Graded Materials), which cannot, or only with great difficulty be processed with conventional methods ● Parts can be produced at near net shape ● Expensive production steps can be skipped; for example the application of adhesive and solder between the backing plate and the friction material and also the final calibration. Even the copper plating of the carrier might be omitted. POWDER SHAPING TECHNOLOGIES 3

Applications Dr. Fritsch has more than 60 years of experience in the production of FAST-DirectHot-Presses for industrial applications. The machines are designed for a daily 3-shift operation, all reasonable work processes are automated and easy to operate. The equipment is arranged in a compact housing. The risk of operating errors is re­ duced due to the intelligent programming and not freely accessible components. In co-operation with our customers and due to continuous development and optimization we succeed to enter into new Sputter Targets application areas.
