Why Injection Molding?
Because it’s a better process! As of today it’s the best process for making rubber parts!
Mixing the rubber, preheating the rubber, adding more heat through injecting, injecting into a mold that’s already closed are all good things for processing rubber. And each of these steps give you additional parameters you can control to optimize your production, quality, labor and scrap.
US Molding Machinery presses give you the ability to control these parameters and many, many more.
The ability for you to optimally control these parameters is why you need to evaluate injection molding for your company. We’ve listed several specific benefits below and why they occur.
Better fill due to consistently heated rubber and injecting into a closed mold.
Consistent cure due to preheated rubber and consistent contact with the mold.
Homogeneous material due to mixing.
Rubber is preheated by screw.
Rubber is heated externally.
Rubber is heating during inject.
More rubber is in contact with the mold.
Exact amount of rubber is used.
Design more "detailed" parts.
Reduce cure Time / cycle Time.
30% – 80% reduction in time.
Mold closes parallel.
Closed mold sees even pressure.
Rubber flows with less pressure when warm.
Mold already closed.
“Post Cure” Labor
Less tear away trim.
Better rubber flow.
Eliminate material weighing and prepping.
Precise shot size - machine measured and applied.
