Manufacturing stages by Staub

 

First stage :

Manufacture of mother moulds (male and female) in resin.


 


This is followed by two manufacturing processes :

The pressing process :
  • Lumps of clay are first cut to shape then squeezed between male and female moulds.
  • The finishing touches are added then they are left to fry for 24 hours in a damp room.
  • When dry, each piece is individually finished off by hand, imperfections being corrected with a knife and sponge.



  Pressure casting :
  • Hydraulic pressure is used to inject liquid clay -called slip- between two resin moulds.
 


The finishes touches then begin


  • Once out of the machine, products are dried in the open air a dryer at 60°C.
  • Products are then enamelled. The enamels used are lead-free and recycled. They are cooked at 1,000°C to vitrify the enamel in a direct current electric furnace.

 


Finally, products are sorted and packaged

Quality controm is ensured throughout all stages of production.
