Latest Patents
Tateyama's latest patents include a method of dyeing or reforming injection, blow, or compression molding. This innovative molding method provides a homogeneous surface without any patches by dyeing or reforming a resin surface in a die concurrently with molding. After thermoplastic resin is filled in a die cavity, a mixture gas of carbon dioxide and a dye, or a reformer, is injected between the resin and the die to form a clearance. The pressure of the mixture gas is maintained at a constant level, allowing it to dissolve in the molded surface. The molded product is then taken out after exhausting and cooling the mixture gas. Another significant patent involves controlling the forward movement speed of the screw in an injection molding machine. This method ensures that the internal pressure of the mold reaches a predetermined target pressure during the filling and deceleration steps.
