In the first step, the first barrel fills the substrate set of
cavities.
Transitions between wall thickness should be gradual
to reduce flow problems such as back fills and gas traps.
This
helps TPE flow into and fill thin walled sections commonly encountered in over-molding.

• Replace lead while providing uniform shielding
performance
• Radiation shielding up to 140KeV
• Improve glasses design
• Compliance with Radiation Protection Regulation: Adult
eye exposure must be below 20 mSv per calendar year
• Conducted extensive testing to ensure comparable and
uniform shielding performance
• Improved geometric flexibility
• Lowered shielding component costs 30-50% by
eliminating machining and assembly steps (associated
with lead)
• Reduced weight of the glasses and enabled a more
ergonomic design
• Eliminated disposal concerns associated with lead
