Company
ECT-KEMA GmbH, based in Markersdorf near Görlitz, develops, designs, builds and supplies machines and systems for preparation, dosing, forming and handling of ceramic and similar plastic masses. The product range includes medium- and high-pressure vacuum extruders (screw diameters 250 to 950 mm), pelletizers, piston presses, feeders, milling and crushing systems, cut-off machines as well as vertical lathes for forming ceramic insulators. In addition, the company manufactures extrusion tools such as pressure heads and dies, including honeycomb tools up to 650 CPSI, made from tool steels, stainless steel, hard metal, ceramics and plastics. An in-house technical centre offers feasibility tests, rheological characterisation and extruder simulations. Customers are found in the chemical industry, electro-ceramics, the building materials, automotive, environmental and recycling industries as well as the tool, agricultural and metallurgical industries; deliveries are made worldwide.

Materials & Processes
Medium- and high-pressure vacuum extrusion
Extruding, kneading and de-airing plastic and ceramic masses into solid and hollow strands, with pressures up to 150 bar in stiff-plastic extrusion.
Pelletizers
Extruders with or without vacuum with cutting systems for pellets from residual materials, biochar, animal feed and aggregates.
Piston presses
Continuous extrusion by means of piston press for honeycomb bodies, filters and pellets.
Extrusion tools
Design and manufacture of custom pressure heads and dies, including honeycomb tools up to 650 CPSI.
Additive Manufacturing / Concrete 3D printing
Forming of adhesive and rapidly setting masses such as concrete by extrusion.
Insulator lathe AKD series
Vertical turning of ceramic insulators with diameters of 200 to 500 mm and heights of 500 to 3000 mm.
Laboratory service
Feasibility tests, rheological characterisation, mass and raw material analyses as well as extruder simulation in the company's own technical centre.
Tool steels
Material for high-performance precision extrusion tools.
Rust- and acid-resistant materials
