Tool making


The best shape for your product

With the shaping tools from ECT-KEMA, there are no limits to the design, development and manufacture of your products.
Ceramic, oxide, mineral, organic, inorganic, metallic and non-metallic materials can be extruded into almost any required shape – in a completely individual process that is optimized for the specific application.

Pressure heads
In the pressure head of the extruder, the body is prepared for subsequent shaping. To ensure optimum extrusion, the pressure head can be equipped with different features:

  • Temperature control
  • Wear inlay /­ wear protection
  • Centring device for augers
  • With and without strainer plate
  • Optimized feed geometry
  • P/­T sensor connection‎
Dies
Different geometries, filigree structures – every custom-made die is as individual as your product:

  • Honeycomb tools up to 650 CPSI
  • Symmetric and asymmetric perforation pattern
  • Tube and roller tools, open and closed
  • Pelletizing tools and dies
  • Multichannel dies
  • Dies for heavy clay ceramics
  • Flat membrane tools
  • Foil tools
  • Special profiles‎


Safety and comfort - Starting and extrusion aids avoid die damage and pin breakage, especially during commissioning, die changes or cleaning.
Materials
In line with your requirements, we make high-performance precision tools from:

  • All common tool steels
  • Stainless and acid-resistant materials
  • Hard metal
  • Ceramics
  • Plastics‎

Simulations

Simulation steps

Simulation steps
For optimization of the tool for a precision shaping process, we determine key parameters:

  • Density
  • Water content
  • Penetrometer value upstream of the extruder
  • Penetrometer value downstream of the extruder
  • Yield point
  • Bingham viscosity
  • Slippage
