DSP 517

Product catalog summary

Main Features

High Quality: Precise control of sintering parameters such as temperature, pressure, stroke, and time.
Flexibility: Short cycle times due to direct heating of the sintering mould, with typical sintering times ranging from 15 to 45 minutes.
High Productivity: Large surface graphite electrodes allow for the sintering of multiple clamping frames simultaneously.
Low Graphite Costs: Utilizes closed vacuum/inert gas equipment.
Easy Handling: Features a touch screen panel and programmable control for up to 100 sintering programs.
Easy Maintenance: Main components are easily accessible.
Pressing Force: Switchable between 39 – 461 kN and 51 – 603 kN.

Options

Increased maximum heating power to 240 kVA.
Various special cylinder and pressing force configurations.
Insulation of the vacuum chamber with graphite felt.
Additional features like a pyrometer, active suction system, UPS for PLC, and barcode reader.

Functioning

The DSP 517 operates as an automatic pressure sintering press for metal, ceramic, or resin-bonded workpieces. It uses resistance heating and hydraulic pressures up to 300 bar. The process involves placing a sintering mould on the lower electrode, controlling temperature via thermocouple or pyrometer, and executing a sintering program with selected parameters.

Technical Data

Electric Power: Standard max heating power is 205 kVA, with options up to 240 kVA.
Cooling Water: Consumption is approximately 220 l/min at 20°C.
Compressed Air: Consumption is approximately 20 l/min with a pressure of 4 – 6 bar.
Inert Gas: Consumption ranges from 300 – 1000 l/h, with a pressure of 1 – 5 bar.
Suction System: Recommended air flow rate is approximately 800 m³/h.
Pressing Force: Various configurations available, with nominal and differential switching options.
Graphite Electrodes: Standard dimensions are 350 x 350 x 80 mm.
Temperature Control: Thermocouples and pyrometers available for temperature ranges up to 1400°C.
Dimensions and Weight: Machine weight is approximately 5500 kg.
