2 Technical specification DSP 520 FAST/SPS sintering is a technology with many advantages compared to conventional sintering techniques: FAST (Field Assisted Sintering Technique) FAST/SPS does not heat up the sinter chamber but the sinter part or the mould directly. Very short sinter cycles are achieved by that. This technique is suitable for electrically conductive as well as for non-conductive materials. Depending on the material, a sinter cycle usually takes between 15 and 45 minutes. PRECISE All sinter parameters can be controlled exactly. A process monitoring software shows all information and administers the process data. Sinter programs can be adjusted to your individual requirements. Near net-shape production is a must, especially when working with precious materials. Thanks to the precise control of all parameters like pressure, temperature, travel distance and time, it is nothing to worry about. ECONOMICAL FAST/SPS is ideal for both, research and development and mass production. The machines are designed for high output and for 24/7-operation. Operation is easy and most machines can be fully automated and integrated in an automated production environment. FUNCTIONING The filled die is put into the machine manually or automatically, depending on the machine configuration. The sinter program is initiated by one click. The typical sinter programme is partitioned into 3 steps: a) De-waxing with vapour extraction and air flushing b) Sintering with inert gas flow c) Cooling with inert gas flow Heating velocity, sinter temperature, pressure and time can be set individually and can be adjusted to your materials. After the sinter program has been completed the die is unloaded manually or automatically and a new die is put into sinter position. DSP 520 Seite 2 von 4 V ; jh
