New Spring Cups from Progressive Components Allow for Safer and Easier Spring Installation

Press release submitted on behalf of Progressive Components.

Progressive Components (Wauconda, IL) announces the release of the new Spring Cup ejector system component. This product speeds and simplifies the safe assembly of spring-loaded ejector systems, helps prevent damage to ejector pins and components, and optimizes valuable space within a mold’s design.

Mold assembly can be cumbersome and unsafe when overcoming spring pressure within an ejector system. Instead, Spring Cups allow for all ejection components to be installed first, without the ejector springs installed. This allows the ejector system to be tested or “dry cycled” to verify the mold components were assembled correctly and that there are no binding issues, which can cause damage or premature wear to pins, sleeves, and lifters. After verification, the mold’s springs are then installed, and the Spring Cups bolted in last.

Spring Cups speed mold assembly. Traditionally, a common requirement on a toolroom checklist is for the entire mold half to be assembled without springs, followed by a check that the ejector system is moving smoothly, then disassembly of the mold, springs added, and then reassembled. But with Spring Cups, after verification of smooth ejection movement, assembly is completed, which means that a mold’s core half need only be assembled once. These steps are apparent to toolroom personnel, as Spring Cups feature laser etched text that states “Install last” and “Uninstall first.”

Mold designs benefit from the use of Spring Cups. An additional advantage is that Spring Cups can also serve as a PKO Extension, allowing two functions to be located at one location.

Product features:

  • Springs are installed last, which enables verification of a smooth-running ejector system prior to spring installation.
  • Assembly is safer by eliminating spring-loaded moving mold plates.
  • An application-suited spring can be selected by designers and placed away from more valuable locations within the mold.
  • Can be placed at PKO locations as a space-saving option.
  • Spring Cups can retain springs in other locations, such as cavity-half floating plates.
  • Available in seven sizes to accommodate common spring diameters and standard plate thicknesses.
  • CAD geometry is offered in various formats, including SolidWorks, NX, VISI, Parasolid, ACIS, and IGES.
