Manufacturing of an OBVR Fuel Emission Tube for the Automotive Industry
Prior Product:

Akron Polymer's customer that is a major tier 1 supplier to the automotive industry used a bulky EP rubber hose assembly for an automotive emission vent application. The assembly required a formed EP rubber hose; injection molded & inserted hose connector and hose clamps to secure each extremity.

Akron Polymer's Solution:

Using the customer supplied specifications the tube assembly was redesigned by the Akron engineering staff. The new, all Nylon (PA) 12 tube assembly featured an extruded thermoplastic tube that was formed into a complex 3D shape and an over-molded glass reinforced Nylon (PA) 612 connector at one end. Akron developed all of the form tooling, molds and fixtures in house.

Results/Value:

The customer was able to drop in the Akron Polymer tube assembly onto their On Board Vapor Recovery System. The redesign resulted in significant costs savings for the customer as well as a 35% reduction in weight. Akron Polymer was able to completely redesign, develop, and manufacture this custom molded assembly in only 14 weeks.
