Electric Automatic Reaction Injection Mold, Power : 1-3kw

Reaction Injection Molding (RIM) injects a rapid-cure resin and a catalyst into the mold in two separate streams. Mixing, and the resulting chemical reaction, occur in the mold instead of in a dispensing head. Automotive industry suppliers have combined structural RIM (SRIM) with rapid preforming methods to fabricate structural parts that don’t require a Class A finish. Programmable robots have become a common means to spray a chopped fiberglass/binder combination onto a vacuum-equipped preform screen or mold. Robotic sprayup can be directed to control fiber orientation. A related technology, dry fiber placement, combines stitched preforms and RTM. Fiber volumes of up to 68% are possible, and automated controls ensure low voids and consistent preform reproduction, without the need for trimming.
