Progressive Components Standardizes
Expandable Cavities 

Utilized as a custom solution for years, Expandable Cavities now have been released as a standardized, off-the-shelf component by Progressive Components. 

The Ex-Cav™ is designed for molding undercuts located under the part surface, such as barbs and protrusions, and is offered in four sizes, ranging from 20mm to 50mm. 

Expandable Cavities simplify mold designs by eliminating the need for complex side action assemblies.  In addition, their compact design enables the use of smaller mold bases and a smaller press.  

The Ex-Cav standard includes two mounting styles, with CAD geometry available for ease of integration into upcoming mold designs.  All Ex-Cav’s can be ordered with molding details already machined, saving time.

RJG Introduces Process Stability Dashboard 

RJG has assembled a suite of tools to manage quality for all molds that run in molding plants whether they have in-cavity sensors or not. 

An overview is provided on the eDART™ network that shows each machine’s status and how much it has deviated from the process that should be running.  Once a proper process “template” is recorded the eDART sends a record of any deviations in machine speeds and pressures from that template to the overview.  A quick scan down the overview screen lets one know about any processes that aren’t being run correctly. 

The eDART also observes changes in material viscosity comparing them with the value from the saved template.   

RJG recognizes that it is not practical to put cavity pressure into every mold all at once. The next best thing is to monitor the machine and material and make corrections in a systematic way. If molds require in-cavity sensing one can add sensors to them as needed. These are then displayed in a third meter that tells if all cavity pressure sensors match their templates.
