The
manufacturer produces 7.5 million cases per year, and
was using liquid injection molded (LIM) silicone for this
part.
However, the silicone was sticking to the mold
and inner workings of the molding machine.
This not
only caused a high scrap rate, but also led to frequent
interruptions in the automated process so that the mold
and machine could be cleaned.

Compared with
a traditional painting process, injection-molded Artisan materials also offer additional sustainable benefits:
energy use and VOC emissions are reduced by eliminating secondary painting or in-mold labeling.
If material is not in the
recommended moisture percentage for molding, dry
material until it is in the acceptable range for molding.
If material is not in the recommended

It has great strength, is inherently resistant to solvents, as well as heat, abrasion and friction and shrinks very little during molding.

During molding, longer fibers intertwine and align with polymer flow to form an internal skeletal network.

Typically for injection molding processing 12 mm (0.5 inch) long pellets are the standard length to facilitate material handling and feeding into processing equipment.
