casting machine

Tape casting is a casting process used to manufacture thin layers from a slurry cast onto a flexible base. KMS produces tape casting solutions for R&D to industrial production of applications such as ceramic tape casting (e.g. LTCC/HTCC/MLCC foils), solid oxide fuel cell (SOFC) ceramic, electrolyte and electrode layer casting of batteries, adhesive layer coating on metal foil, …. Our speciality is the complete integrated solutions and accompanying our customers from their initial development to scaling them up to large production.

Machines

Compact

KC300

  • Compact, Continuous system for casting ceramic tape on coated PET-film.

  • One of the smallest and most accurate machines on the market

  • Doctor Blade or / and Slot Die

  • Easy to operate, low maintenance

  • Serial production or lab operation

cast thickness

The KC-series casts ceramic tape to a thikness from 3-400 microns(dry) depending on the slurry (solid content, rheology,etc), Thinner casting(1um) has been done with special formulations.

 

cast Method

Doctor-Blade Technology, ” Blade over Roll” type casting method. Precision ground carbide casting blade, Thikness variation of the PET-film are automatically eliminated. The model KC300 is prepared to accept a slot die ( AAA-grade), allowing both continuous and intermittent coating e.g for lithium-ion batteries.

 

Dimensions

approx. 110cm high (inch.monitor / touch screen approx. 160cm high). Length: KC300-7 approx. 265cm

 

Weight

approx.500-600kg, depending on configuration.

 

construction

Stainless steel welded frame, stainless steel enclosure. easy to clean up slurry spills.

 

air flow

Two fans draw air through a HEPA filter. One fan provides intake air while the other is used to exhaust air. Each fan is independently controlled so the drying chamber can operate at a positive or negative pressure. Negative pressure is used in a clean room and positive pressure is used if the machine is not in a clean room.

 

tape cleaning

Each side of the carrier film is rolled over a apecial “tacky” roller to remove debris before enterning the casting chamber.

 

drying

Five/seven individually controlled sealed heating plates. Temperature settings and tolerances are set via the touch screen. The intake air has a heater as well (counter flow drying)..
