A casting machine refers to specialized equipment used for producing cast films. The high-precision electronic ceramic casting machine employs alumina as the primary raw material for ceramic casting. First, the finely ground powder is mixed with binders, plasticizers, dispersants, and solvents to form a slurry with a certain viscosity. The slurry flows from the hopper and is spread onto a dedicated carrier tape by a doctor blade at a specific thickness. After drying and curing, the film is peeled off to form a green tape. The green tape is then subjected to processes such as punching and lamination according to the required dimensions and shape of the final product, resulting in a semi-finished blank ready for sintering. This method offers advantages such as low cost, high quality, non-toxicity, and a simple production process.
