Squeaking problem silenced with lubricated nylon

When DaimlerChrysler realized they had a problem with squeaking doors on their full size Dodge vans they switched to Lubriloy RF-30, a glass-fibre reinforced, lubricated nylon 6/6 from LNP Engineering Plastics, for the mini wedge in the swinging horizontal tail door.

“The mini wedge is a small plastic part that acts as a stabilizer to keep the van’s tail door from jumping up or down or chucking,” explains Morry Almacher, engineer at DaimlerChrysler. “When the door is closed, it essentially “wedges” into the mini-wedge which stabilizes it,” he said.

The use of glass-fibre reinforcement gives the composite added strength, stiffness, rigidity, and impact strength. Lubriloy RF-30 composites have significantly lower coefficients of friction, improved wear resistance against metals and extremely high limiting pressure velocity.

An important factor in the switch to the Lubriloy RF-30 composite was the fact that it is available in glass reinforced grades. “This allowed for a smooth transition at our molder,” explains Allmacher. “Lubriloy RF-30 met the dimensional requirements determined by the existing 33 percent glass filled nylon 6/6 material being used in the application.”
