Protective eyewear sealing strips must endure prolonged exposure to ultraviolet radiation, ozone, and perspiration without exhibiting signs of embrittlement or cracking prematurely. TYM's LSR molds constructed from hardened tool steels treated with proprietary nitriding processes exhibit exceptional wear resistance resisting abrasive erosion caused by repetitive sliding motions occurring during donning/doffing procedures executed hundreds of times daily by frontline healthcare professionals.
Strategic placement of ejector pins avoids stress concentration points prone to initiating fatigue cracks under cyclical loading scenarios typical of extended service intervals spanning months rather than weeks. Venting channels strategically located around core-cavity interfaces expel trapped gases efficiently, reducing occurrence of voids or porosity defects commonly found in thick-walled sections typical of earplug bodies.
Post-forming operations include precision cutting using waterjet technology to trim extraneous flash remnants cleanly without inducing micro-cracks susceptible to fatigue failure over prolonged usage periods. Secondary bonding procedures join separate hose segments together using proprietary adhesive formulations tested extensively for compatibility with various coolant chemistries prevalent in modern vehicle architectures.
