4 Mold Maintenance & Repair F E AT U R E By Flavio Malosio and Josh Kauzlarich As mold complexity increases, so, too, does the complexity of maintenance, which advances the role of spotting in mold validation. In the highly competitive plastics industry, great emphasis is placed on precision, effciency and productivity, but people often forget about the importance of completing the mold process. If a mold builder invests resources into high-pre- cision machining, yet tests his molds using an overhead crane, how can he assure his cus- tomers that the molds are properly validated? With a high-precision spotting press, a mold builder can say, "This is how we know the mold is accurate." This validation not only completes the mold process, it also provides the quality assurance of a premiere mold manufacturer. As molds become more and more compli- cated, so does the checking and maintenance process. In turn, technology advances and so does the role of a spotting press to validate a mold. Having a high-precision spotting press provides a shop owner several advantages: Safety. The frst criteria in the design and manufacture of a spotting press should be safety. A high-precision spotting press minimizes dangerous mold handling associated with cranes, forklift trucks and other lifting equipment. Differ- ent from the mechanical multi-hole or toothed-bar system, a high-precision spotting press includes a safety device that prevents the press ram from falling if the hydraulic system fails. Safety devices are The Hidden Value of a Spotting Press Spotting operations of a high-precision press are intuitively controlled through a control touch panel that makes press functions clear, straightforward and simple.

A high-precision spotting press is designed intrinsically with the maintenance crew in mind. Both platens should have the ability to tilt at varying angles, which helps avoid stressful maneuvers when performing mold maintenance by making the molds easily acces- sible. Some presses have a compact design that allows the mold maintenance technician to ap- proach the mold from a variety of angles with a simple tap of a control touch panel. For example, a press with the upper platen rotating 360 de- grees and the lower platen rolling out and then tilting 75 degrees. This same approach can be applied to medium and large molds where the upper platen withholds the capability of fipping
