ADVANTAGE - ZERO CONTACT DURING SEGMENT MOVEMENT
LARGE SEGMENTS LEAD During the mold closing phase, the center core first engages larger segments, designed to make contact before the smaller ones. This allows larger segments to smoothly lead the opening, ensuring efficient and contact-free movement. SMALL SEGMENTS FOLLOW Following the larger segments, the center core smoothly engages the smaller ones, ensuring their synchronized and coordinated efforts. This designprevents contact and additional load on the smaller segments during the mold closing phase. ZERO CONTACT DURING MOTION In the DURA CORE, the absence of physical con- tact between large and small segments markedly decreases wear and tear. This essential innova- tion is key to ensuring a longer operational life for the DURA CORE.
