Platicast-model

tmax up to 2000 °C

Precision fine casting unit with rough vacuum, gas and vacuum tight, 6,6 kW

Applications:

casting, melting, precision fine casting

The Most important characteristics

  • Melting and casting processes with very specific adjustment of atmosphere (f.ex. normal, vacuum, vacuum-protective gas)
  • Casting of metals (f.ex. platinum, gold, silver, German silver, brass, copper, bronze, steel and its alloys) in centrifugal casting process to high quality precision parts.
  • High frequency centrifugal casting machine for jewellery production
  • Max. melting temperatures to 2000 °C
  • Optimal stirring of alloyed metals through electromagnetic forces.
  • Possibility to cast under air and vacuum or vacuum with protective gas purging.
  • Use of casting arm in open state possible
  • Heating of  bigger material quantities in shortest time
  • High energy efficiency
  • User friendliness
  • High quality – made in Germany
  • Easy to handle

Technical Data

General

The machine consists of a fitted with noise suppression high frequency generator with an induction coil power of appr. 6,6 kW and an operating frequency of appr. 1,0 to 1,2 MHz which is mounted together with the under atmosphere or vacuum or vacuum with protective gas purging, working induction melting furnace and centrifugal casting device in a compact, two times lacquered, stainless steel housing. The required space is appr. 1,0 m². (without additional devices). 

Machine control

Hardware

The operation is effected through a 7“ colour-Touchpanel with 10 integrated function keys and integrated SPS function. Local components are used for control of machine functions. 

All inlet and outlets of the sensors and actuators are galvanically separated and MF/HF is fail-safe connected with the local control unit.

The process datas and parameters can be read out over an USB interface.

A well accessible emergency switch off offers additional safety in operation. 

Scope of functions

The self explanatory menu navigation and guided programme processes make a simple operation possible. The optical display of the programme process and the respective working steps inform about the current state of the machine. 

With integrated recipe administration for the melting programmes (the number depends on storage). The compiled melting programmes can be saved on a USB storage medium and and levelled to all further machines of same Lifumat type, without having to compile it new.

The safety supervision of diverse functions is effected with clear text alarm f.ex. cooling water temperature, cooling water flow, cover and door locking, generator stream (power). An optic and acoustic signal is effected at disturbance and casting process end.

Operator language is selectable in German or English (further against surcharge).

The user levels (producer, administrator, operator) are locked. 

Manual function

In order to optimize processes and written melting programmes the process parameters are freely changeable. With status display of hardware inlet and outlet.  

Cooling water connection

With switch off automatic appr. 8 l/min. at at least 3,5 bar, max. 5 bar, at a water temperature of max. 25°C. When using of deionized tube water max. hardening degree 6° German hardness, conductivity max. 200 µS/cm. 

Melting and casting atmosphere

Selectable as melting or casting atmosphere respectively:

  • Normal atmosphere
  • Under gas purging
  • Under vacuum
  • Under vacuum with gas purging
  • Vacuum

A vacuum of max. 1 mbar is reachable with rotary vane pump with 4 m³/h. The pump is not integrated in the machine housing but will be placed next to the machine.
