MOLD INTERLOCKS LT-Series LifeTime Roller Side Mold Interlock
ALIGNING TOOLS IN DIFFERENT MOLDING APPLICATIONS
Alignment of the mold during the process is critical to the reliability and the achievement of high levels of O.E.E. (Overall Equipment Effectiveness), essential for a profitable molding process. Tried and tested the newly designed and upgraded DME LifeTime lock addresses a gap in the Industry helping improve part quality, reduce cycle times and increase production uptime. Designed for the best possible lifetime performance.

CHALLENGES OF ALIGNMENT
Several factors can challenge alignment through the life time of the tool: thermal expansion, aged equipment, worn leader pins and bushings are just some of the variables. HEAT VARIATION Heat variations can cause misalignment of the mold over time. Managing temperature changes in stationary and movable mold halves is critical: 1. Mold cooling, including the temperature differential between mold halves. Steel grows approximately 0.0000065 inch for every degree Fahrenheit of temperature differential. When A and B halves vary by as little as 20˚F and the mold is 30 inches long, the difference in plate lengths is about 0.004 inch… enough to start wearing of the alignment components. To extend mold life, try to keep the all of the mold plates (mold halves) at a consistent temperature. 2. Hot runner system heating. Since these systems are driven by electric heaters, they can be a major contributor to mold temperature variations if proper cooling is overlooked. 3. Insulator plates. As production begins, insulator plates (top and bottom of the mold) will create a temporarily controlled closed environment. But any heat generated within the mold will eventually migrate through the insulating materials into the press platens and affect the alignment of the mold halves.
