Title:
MANUFACTURE OF SYNTHETIC RESIN FLUID CHANNEL FORMING
Document Type and Number:
Japanese Patent JP3717682
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for forming profile shapes of a fluid channel and a fluid channel forming member substantially in a predetermined shape irrespective of heating in the case of manufacturing the member to be connected by heating the member made of a thermoplastic synthetic resin.
SOLUTION: In the case of connecting channel members 1a to 1c made of a thermoplastic synthetic resin, a fluid channel formed of a hole 3 or a groove 4 at a connecting surface 2 between the members is formed in the state of expecting a shrinkage of the channel in advance so as to form a predetermined designed section caused by the shrinkage at the time of heating and connecting the members. The member is closely engaged within a mold 10, the mold is sealed in the state that connecting surfaces to be connected to one another are brought into pressure contact with one another, heated, softened and connected. A deformation of the member in a direction perpendicular to the connecting surface is suppressed by the sealed mold, and an expansion caused by heating the member and a flowed part of the material caused by the pressure contact with the connecting surface are absorbed mainly by the shrinkage of the member.
