Kind Code:
A
Abstract:
An injection molding process for fabricating a Coriolis flowmeter. The process includes the steps forming a material flow path core using a core mold, placing the formed material flow path core into a wrapper mold having a cavity whose surfaces define the exterior surface of the plastic Coriolis flowmeter structure to be formed, injecting low temperature metal or soluble material into the cavity of the wrapper mold, removing the plastic Coriolis flowmeter structure from the wrapper mold, and removing the material flow path core from the plastic Coriolis flowmeter by melting the low temperature metal core or by dissolving the soluble material using hot water.
