Bronze Ejector Bushings Offer Superior Performance for Toughness
Solid bronze guided ejector bushings from PCS Company offer superior performance for toughness, tensile strength and low coefficient of friction.
Solid bronze guided ejector bushings from PCS Company offer superior performance for toughness, tensile strength and low coefficient of friction. Made of solid aluminum bronze, the bushings are available in nominal diameters ranging from ¾” to 2”. Included internal grease grooves help prevent galling, which aids in smooth operation. Other features include, keeping ejector assembly aligned, extending the life of ejection components and better performance than steel bushings.
Understanding the effects of injection on the core, slide and associated components is critical to selecting the best side-action methods for a given application. This first of two articles will discuss the basic physics underlying all side-actions.
Although PERC (Programmable Electric Rotating Cores System) is not a brand-new technology, it warrants a second look as a way for moldmakers to provide another value-added service to their customers.
Simple cylinder calculations provide good first look comparisons for proper sizing when moldmakers are considering the most suitable side-action option early in the mold design.
