Strategies to counteract failure in this “new
normal” of heightened disinfection are two fold:
One, selecting materials with improved chemical
resistance and two, modifying part design to
reduce residual stresses.
The inside
diameter of the boss should be the diameter
of the core or screw being used, and depends
on the type of fit desired, interference, and/
or clearance.

resistance or other challenges, please contact

If a reinforced substrate material is used a high hardness abrasion resistant steel may be required.
Most GLS materials overmolding materials are generally non-abrasive / non-corrosive and replicate the mold surface fairly well.
For conventional cold runner tools, full-round runners are best because they provide the lease resistance to flow and minimize cooling in the runner.
