An injection-molding process using blow-mold resin and moulded plastic container

摘要

The fabrication of an injection-molded plastic part using a blow-mold resin includes a first step of modifying an injection-molding machine (26) by enlarging resin passages in order for that machine to accept a more viscous resin. The next step in the fabrication process is to provide a mass of blow-molded resin heated to a viscosity suitable for the modified injection-molding machine. A third step is to introduce the mass of blow-molded resin into the modified injection-molding machine. The fourth step is operating the modified injection-molding machine in a manner consistent with the normal operation for injection-molding of the desired plastic part. A part of the present invention is the specific method of modifying component parts (28; 36; 38) of the injection-molding machine so that those component parts are compatible with a more viscous plastic resin.
