Our Process

Ateliers du Futur by Avignon Ceramic
Mix
Avignon Ceramic can offer 4 main materials, to be defined according to technical characteristics of the piece to be obtained :
  • H -- 20 EQX : used for small ceramic cores, Equiaxe process (EQX), air or vacuum cating. Good behaviour during casting, good chemical leachability.
  • H -- 20 DS/SX : used for small ceramic cores, Directional Solidification (DS) or Single Crystal (SX). Good behaviour during casting, good chemical leachability.
  • S -- 20 EQX : material showing high permeability, used for large ceramic cores, Equiaxe process (EQX), air or vacuum casting. Good behaviour during casting, good leachability with chemicals or water under pressure.
  • S -- 20 DS/SX : used for large and complex ceramic cores, Directional Solidification (DS) or Single Crystal (SX). Good behaviour during casting, good chemical leachability.
  • Aluminium : Zircon and others on demand
Injection
Standard processes :
- High pressure
- Medium pressure (slurry).

On demand : Pouring
Firing
Capacity : 14 kilns
Finishing
Avignon Ceramic has got a manual finishing workshop and a mechanized one finishing machine (CNC)
Inspection
Dimensional inspection
Avignon Ceramic has got several dimensional inspection means according to the type of ceramic cores :
  • classical equipments : calliper-square, palmer, profile projector...
  • control gauges belonging to every ceramic core : Go-Nogo...
  • electronical measuring station (pro-control) for big quantities
  • 3 tri-dimensional machines to inspect mainly large and complex ceramic cores

An inspection and registering frequency is agreed with our customer according to critical dimensions and process capability, and can go up to 100%.

Impregnation / Coating
Ceramic cores are fragile. They are impregnated in a substance to strenghten them and avoid any breakage during transport and handling.
In case of use of the ceramic core with reactive alloys, Avignon Ceramic can offer its coating capacity to its customers. It is an inert alumina-based coating aimed at avoiding any reaction between metal and ceramic.
Packing
The ceramic cores have been finished and inspected : they are now ready to be packed and shipped to our customers.
Specific packagings according to ceramic cores type, strenghtened for export.
