As an industry innovator, NCC offers a unique Structural Reaction Injection Molding System (SRIM) designed for rapid injection-compression molding using multiple port urethane resin systems. The $2.5 million molding cell has a shuttle type press with 140” x 120” platens and 126” of daylight and an 85” stroke. The SRIM system delivers higher stiffness and increased strength when compared to sheet molded compound parts. While sheet molded compound produced parts offer a good surface finish they lack strength. The SRIM system uses an advanced combination of urethane and resin which, when poured into a mold, produces a very strong structural composite part. The SRIM primarily targets the automotive and recreation equipment markets and is suited to high volume large and multiple part production.
Additional Equipment Details
The press also has four 12” stroke leveling cylinders and is designed for short cycle times with 180 inch per minute (IPM) rapid traverse, a maximum 59 IPM feed with a computer compensated leveling system that maintains the press platens parallel to .010” within 10 feet. The press is linked to three Cannon A-200 gear type urethane injection systems with 300-gallon daytanks. The injection units can be sequentially or simultaneously fired and have injected as much as 26 pounds of resin in six seconds. Full pressure, temperature and real time platen position sensing make this molding cell second to none.
