Designing and molding complex sealing assemblies for intelligent electronic devices is a core expertise of Minnesota Rubber and Plastics (Minneapolis, MN). Typical of this expertise is a test collection cell assembly that the company redesigned and manufactured for use in a printed circuit board (PCB) contamination tester. To achieve the vacuum improvement and testing consistency, Minnesota Rubber and Plastics has provided a new design, which:

  • Changed the base material to higher quality polypropylene.
  • Improved cooling lines in the mold.
  • Refined molded part dimensions to increase component stability.
  • Designed a new machine molding cycle to achieve desired moldability and component cooling.
