Multi-station machines

pouring station with temperature measurement
drawing station with automatic lock inserter

For quantity and mass production with quantities of up to 200 pieces per hour.

 

On this machine type, several moulds are used parallely. All required work steps are carried out simultaneously - casting, centrifuging, cooling, pipe drawing, brushing of mould inside and lock seat, inside coating of moulds as well as withdrawing, coating and replacing of mould lock.
  

All stations work fully automatically, a manual intervention is only required in case of malfunction or for modifications of the work steps. When the work steps on the individual stations are finished, the moulds are automatically transported to the next station and the work steps are carried out again. .

 

Depending on the product, production quantities of up to 200 pcs/h are possible. In our Karlstadt works we maintain ourselves such a plant for the production of drainage pipes.

 

This machine type is ideal for the mass production of cylinder liners and cast iron pipes.

 

 

Every machine of this type has a basic equipment of:

  • roller stations with controlled electrical drives
  • SPS control
  • process visualization with display of all parameters and machine operation
  • gas burner for pre-heating of casting equipment 
  • scale for dosing of the required liquid iron quantity
  • casting station with casting bucket for the measured quantity of liquid iron, and pouring nozzle for optimal melt guidance
  • measurement of mould temperatures on 3 positions
  • controlled mould cooling
  • automatic brushing of mould inside and lock seat
  • automatic lock treatment (cleaning, cooling, coating)
  • spraying lance with possibility of electric drive (velocity and quantity of spray cycles adjustable)
  • various splashboards with integrated connections for dust extraction equipment
  • full hydraulic equipment for all required movements
  • pipe drawing equipment
  • pipe pacemaker as a cooling distance
  • pipe outside brush

 

 

Molten iron delivery with casting furnace

automatic dosing of molten iron for a product
3D CAD model multi-station machine with casting furnace

On this machine type, the supply of molten iron through a casting furnace is the best solution.

A movable casting bucket is equipped with a balance. The value reported by this balance is analysed by our machine control unit, which passes on the corresponding signal to the plug control of the furnace. This way, the molten iron quantity taken from the furnace can be dosed exactly. The dosing is fully automatic and adapted to the machine cycle.

Running since March 2008

Since March 2008, two identical plants of the type B80/1200 have been running on the premises of a well-known international automobile supplier, with a total output of approx. 5 million cylinder liners per year.
