If a spring fails due to fatigue, the effect on the conveyor can be devastating – leading to a cascading failure of additional springs as they take on increased, unintended loads. THE IMPACT Not only did the Gordon Composites vibratory springs outperform the company’s originally specified spring components, they provided a number of additional benefits: Ready-to-install springs reduced labor and simplified installation Unlike alternative springs, Gordon Composites springs are factory machined to the required size and pre- drilled for a significant reduction in cutting and drilling processes and allowing valuable labor time to be allocated elsewhere.

This often causes additional damage to the motor’s lower unit, costing up to several thousand dollars to repair. The addition of a toughening agent to the long fiber composite provided improved vibration damping, according to Stahl.

In addition, the MIC process avoids VOC emissions associated with painting. Smartbatch™ FX for Paint Replacement is a combination of color and additive concentrates that help manufacturers replace paint and meet performance requirements for a variety of applications.

CASE STUDY: EXCELITE™ IM CHEMICAL FOAMING ADDITIVES THE CHALLENGE With more major OEMs introducing lightweighting initiatives, the use of chemical foaming additives (CFAs) is becoming more common among automotive injection molders. This offered significant improvement in dispersion and dimensional stability, and an additional 2% density reduction, lowering final part weight. Dispersion and performance of the additive was critical to success.
