CASE STUDY: P-80® Grip-it Quick-Drying Temporary Rubber Assembly Lubricant Allows Dishwashers to Pass Critical Drop Test

The following is a case study from a major appliance OEM. It shows how using the proper P-80® assembly lubricant assisted in reducing drop test failures. Assembled dishwashers routinely undergo post assembly drop testing. During testing, a number of failures occurred. P-80® Grip-it was trialed and selected because of its lubrication and adhesive qualities. Switching to P-80® Grip-it solved the problem by significantly reducing drop test failures.

CASE STUDY: P-80® Grip-it Quick-Drying Temporary Rubber Assembly Lubricant Allows Dishwashers to Pass Critical Drop Test

Test Results:

  1. P-80® Grip-it reduced failures allowing dishwashers to pass drop tests consistently.
  2. Easier assembly installation.
  3. Greater hose removal force.

Challenges: A dishwashing manufacturer was experiencing failures during their six inch drop test. Specifically, a connection of a return hose to the sump was susceptible to excessive tangential stress when the dishwasher was dropped at a certain orientation. The return hose separated slightly from the sump, causing leaks during the initial operation. In order to simulate any problems during delivery and installation, the drop test is performed to evaluate the robustness of the dishwashers.

Solution: Design engineers trialed P-80® Grip-it as a replacement for the current lubricant. Grip-it’s dual properties of lubrication and adhesion offered a better outcome.

Grip-it passed the prototype test phase and was moved into production. Assembly workers commented on Grip-it’s superior assembly lubrication over the previous product. Also, Grip-it provided detergency, which cleaned the hose assembly and adjacent areas. Most significantly, the slightly tacky residue of dried Grip-it increased the removal force to 33 pounds, which was found to withstand the tangential stress subjected during the drop test.
