In an effort to strengthen the bushings, the company’s engineering team tested materials from several suppliers, but the LubriOne™ wear-resistant compounds from Avient were the most intriguing.
But the specific product that would meet all of the company’s requirements didn’t exist.
The company, which does its own injection molding, found that the polyamide and LubriOne™ combination generated a 50% reduction in scrap rates.

It is better to
fill out the part at slower speeds in-order to let
any compressed air escape, and to get the best
surface finish on the part.3
• Using all of the previous settings, record the
Transfer Pressure, Fill Time, and Injection
speed
• Reduce the injection velocity by 10% and
record the same values

• Keep reducing the injection velocity until a
fill time of 10-15 seconds is reached
• Calculate the Relative Viscosity for each of
the Injection Speeds using the equation
above (Transfer Pressure * Fill Time)
• Calculate the Relative Shear Rate for each of
the injection speeds using the equation
(1/Fill Time)
• Plot the points on a graph and find the
optimum velocity
• The optimum velocity will be where the
curve starts to level out
In figure 48 above, the optimum velocity is where
the plotted line crosses the black trend line;
therefore the optimum velocity would be about
1.00 in/sec.
