Latest Patents

Mold for Molding Optical Disc. This invention describes a mold with two members that come together to form a cavity. One member includes a recess, while the other has a body fitted with a plate-like sintered ceramic component that provides a flat seat for a detachable disc-shaped stamper. The ceramic material’s high Rockwell hardness is intended to help protect the seat surface from damage over extended use.

Method for Manufacturing Shaped Articles by Injection-Blow Molding. This method begins by injection-molding thermoplastic material onto a core to form a bottomed parison. After cooling, the parison is removed, reheated to a specified temperature, and transferred to a blow-molding mold, where it is shaped.
