ABSTRACT:
An ice blasting apparatus comprises: an ice making device operating a cutting blade to shave off ice freezing on an inner wall of the freezing casing and continuously discharges the shaved ice as flake-shaped ice pellets; an ice mixing tank mixing the ice pellets and water and maintaining the resulting ice slurry at a predetermined concentration with a concentration sensor; and a blast gun blasting the ice slurry. A trimming method is performed on a film insert molding with a film material adhering to a face of a resin molding and extending beyond a periphery edge of the resin molding. A blast gun facing the face with the film adhering to it blasts ice slurry of a required concentration toward the vicinity of the periphery edge of the resin molding to remove the unnecessary portion of the film material extending beyond the periphery edge of the resin molding.
