Tape casting machine refers to the special equipment used for making tape casting film. The high-precision electronic ceramic tape casting machine is used. Aluminum oxide is used as the main raw material for ceramic tape casting. First, the crushed powder is mixed with the binder, plasticizer, dispersant and solvent to make a slurry with a certain viscosity. The slurry flows down from the hopper, is scraped and coated on the special baseband with a certain thickness by a scraper, and is peeled off from the top to become a film of green belt after drying and curing, Then, according to the size and shape of the finished product, the green belt is processed by punching, laminating, etc. to make the finished blank to be sintered. The utility model has the advantages of low cost, high quality, no poison, simple production process, etc.
