Manufacture of molded product e.g. can, involves coating negative contour with suspension containing water-soluble non-polymer and solvent, forming ceramic or metal powder, removing solvent and obtaining matrix of polymer molecule

摘要

Negative contour of molded component is coated with a suspension containing water-soluble non-polymer, solvent for polymer, and water to form soluble and powdery ceramic or metal powder. The solvent is then removed, and ceramic or metal particles precipitate polymer. Matrix consisting of dimensionally stable polymer molecule is formed on the resultant material to obtain molded product.
