Abstract: Provided is a method for crimping a thermoplastic member which allows a first member made of thermoplastic resin to be mounted on a second member at a high mounting strength without complicating the fabrication process and without causing any reduction in the production efficiency. After an entire portion of the first member that is to be crimped is thermally melted or softened, the portion is deformed and crimped by using a crimping die having a die surface which is at a temperature lower the melting point of the thermoplastic resin. Therefore, the deformed portion is given with a uniform internal structure free from internal defects such as cracks and interfaces. Because the interior of the crimped portion remains to be hot as compared to the surface portion which is in contact with the crimping die during the crimping process, a certain pattern of internal stress is produced in the internal part which opposes the internal stress of the surface portion as the deformed portion cools and contracts.

Abstract: A flexible pipe connector is disclosed for connecting to a hard plastic pipe. The flexible pipe connector, preferably made of polyethylene, has a tubing member which defines a cylindrical wall with inner and outer surfaces, the cylindrical wall having a male end which has a plurality of undercuts formed on the outer surface. The male end with the undercuts is inserted into the female end of a hard plastic pipe with a solvent weld glue applied at the inner surface thereof. The solvent weld glue liquifies the inner surface of the pipe's female end to form a liquified layer of hard plastic which is received in the male end's undercuts and then hardens into a reconfigured solid layer. In this manner, the flexible pipe connector, which is inert and normally cannot be attached with glue to a hard plastic pipe, can be sealably secured to a hard plastic pipe as the liquified layer solidifies within the undercuts to prevent separation of the pipe connector and the hard plastic pipe and to provide a seal therebetween.

An optional stacking and fusing procedure is also described to facilitate shipment of frame members prior to assembly.
