It is possible to strip undercuts for parts molded of these processes in some cases and threads can be molded-in. However, side actions or split cavities, as would be required for details A and G, are more commonplace. Threaded inserts, like those at E and H, can also be molded-in. However, it may be more advantageous to emplace them after molding with adhesives since the molding cycle will be shorter and the risk of one misplaced insert ruining an entire moldment is ehminated. The other common methods of assembling compression, transfer, and thermoset injection-molded parts are self-tapping screws (holes can be tapped), adhesives, snap-fits, press-fits, and the usual screw and bolt techniques. None of the plastics welding techniques can be used with thermoset parts. [Pg.691]

The design rules discussed in this section refer to the injection molding of thermoplastics. For the design rules for thermoset injection molding, please refer to Sec. 8.3.5. [Pg.696]

Thermoplastic injection molding came into general practice well before thermoset injection molding, and it is the principal method for volume production of thermoplastic parts. Because thermoplastics are liquefied by heating and hardened by coofing, there are differences between thermoset and thermoplastic injection presses and molds (Figs. 9.10 and Fig. 9.11). [Pg.577]

As with thermoset injection molding, heavily fiber-reinforced parts are also molded from thermoplastics. Such parts still may exhibit creep during prolonged mechanical stress, but they are nevertheless considerably stronger and tougher than the nonreinforced products. Glass-reinforced nylon, for example, is used with the lost-core process for a complex air-intake manifold on a current automotive engine. [Pg.579]

In molding processes such as thermoset injection molding (for example, with phenolics), a hot mold is used to initiate the polymerization/crosslinking reactions. In RIM, mold temperature does not play a key role. The reaction is initiated in an intensive mixing process that blends the reactive chemicals just before and as the reaction mixture is injected into the mold. [Pg.223]

On account of the high degree of design freedom and cost efficiency it offers, thermoset injection molding has established itself as a process for manufacturing thermoset components on a mass-production scale (Fig. 2.18). [Pg.60]

There is no settling of the functional fillers. The materials can be handled by standard machines. In terms of process parameters, however, thermoset Injection molding... [Pg.60]
