METHOD FOR PRODUCING HOLLOW DEVICE, MOLD FOR PRODUCING HOLLOW DEVICE, AND MOLD CELL FOR PRODUCING HOLLOW DEVICE

摘要

PROBLEM TO BE SOLVED: To easily set a fine, complex channel pattern into various patterns, at low cost to improve the design latitude of the channel pattern, and to exactly and easily correspond to various applications. SOLUTION: The channel pattern of a hollow part is specified by a pattern Pk set in a mold 1. A plurality of cells 1A-1H having different functional patterns Ps and a blank cell 1I are used as the mold 1. Each cell 1A-11 is combined optionally as required to set up the pattern Pk of the mold 1, and the channel pattern of the hollow part is specified. COPYRIGHT: (C)2004,JPO
