Chroma Corp. has developed an additive that cuts cycle time while maintaining good mold-fill and dimensional stability.
The McHenry, Ill., firm says its Chroma Rheology Extreme, or CRX, cut cycle time for one large-part injection molder to 20 seconds from 29 seconds in an application where dimensional stability is critical. As well, a closure molder saw a 20 percent increase in throughput after switching to Chroma color concentrates containing CRX, according to Chroma.
Chroma said it also is evaluating CRX's utility in extrusion, blow molding and compression molding.
