*AUTOMATIC SINTERING MACHINE mod. IDRA  3T, WITH THREE STATIONS, 240 kVA, 42TON.

 

Main features

·        Machine suitable for the continuous production of average/large series of diamond segments.

·        Cycle subdivision into three phases / stations:

  §         station 1: preheating

  §         station 2: sintering

  §         station 3: cooling

·        The sintering process  takes place in a controlled atmosphere  in the 3 stations by inlet of inert/reducing gas. During the transport between the stations the mould is protected by a “shower” of the same gas.

·        Temperature control with thermo-couple automatically inserted in the center of the mould.

·        Type K thermo-couple for operating temperatures up to 1000°C.

·        Evacuation system and smoke filtering with water filter.

·        Preheating, sintering and cooling times are the same.

·        Control program with cycles divided into 12 steps. Each step includes:

  §         temperature

  §         pressure

  §         max. power limit

  §         heating time

  §         holding time

·        From 18 up to 64 mould unloading and loading magazine.

·        Automatic mould feeding from mould magazine.

·        18 special aluminium frames.

·        Process data visualisation (set and real) and alarms.

·        Machine complies with EEC regulations.

 

Options

·        Analogic outlet for variable process recording.

·        Pyrometer 350-1300°C to be used alternatively to the thermo-couple.

·        Height segment reading during sintering process (linear transducer on cylinder, resolution of 0.01 mm)

·        Data acquisition system on external PC.

·        Barcode reading system for automatic selection of sintering cycle according to product in aluminium frame, including labelling machine.

·        18/36 moulds loading/unloading magazine.

·        Aluminium frames.

·        Electrodes in graphite.

·        Graphite plates.

·        Graphite moulds.

·        Thermo-couples.

·        Prearrangement for modem installation for remote assistance.
