Ensure Component Integrity With the Right Mold Management System
How tooling engineers can avoid mold performance unknowns and surprises downstream.

Once upon a time … The U.S., Europe and Asia were like three separate manufacturing ecosystems. More often than not, a part would be designed, tooled, run and sold within the same region—and often the same neighborhood—with borders rarely being crossed. Back then, there might be some potential flare-ups at the startup of the tool ("Let's blame the part design!"). But once the tool successfully passed the sampling, that mold was considered to be road ready for producing the parts for the rest of its life cycle. But enough about ancient history that dates way back to the 90s … Everything's Different What's the difference of then versus now? Accountability. Mold builders wouldn't try to sneak in something third-rate for a mold being run around the corner. After all, not only would they have to weather no charge fixes, but it would jeopardize the relationship and future projects to come. To track mold production from concept through processing, one can build a database or access existing mold management products. Images courtesy of Progressive Components. Similarly, component suppliers used to be few in number, and well-known to both the mold builder and the molder, so the accountability factor was present there as well. A name brand "or equivalent" component meant, well, that a name-brand component or an exact equivalent would be in that tool. But today downstream performance problems are more of a risk, for several reasons:
Years ago, despite a sometimes adversarial relationship, molders and mold builders used to be closer—both in proximity and in agreed upon specifications. Now, in a rush for cost savings, specifications are being dropped, and lifetime costs and headaches for tooling engineers are on the rise. "Or Equivalent" There are knockoffs of patented components. Not only is that a no-no for the mold builder, but it exposes the end user to an infringement issue. More important though, is that the mold buyer is being shipped a tool that now contains performance unknowns. One can tour faraway component manufacturing plants and see ancient heat treat-ing processes, titanium nitriding applied so poorly that it's merely for cosmetics, and quality systems with huge gaps. Perhaps an applicable analogy could be that regardless of assurances that it is "equivalent", in most places in the world one would prefer a drink of bottled water rather than a sip from a garden hose to avoid problems downstream! A specific undercut release system was specified, but an imitation (shown here) was not the same tolerance or specification, leading to a surprise in the molding room. How Can You Know? How does one who buys millions of dollars worth of tooling ensure the integrity of the components selected by the mold supplier—or the mold supplier's supplier? Following are some steps you can take and some considerations you should make when ensuring component integrity. Step 1: Get specific. This can be done as extensively as formulating a mold standards document, or as simply as sending an e-mail to the tooling source. Also, referencing your spec on the RFQ, and later on the purchase order also helps. Step 2: Maintain a database. This database then serves as a virtual file cabinet, thereby eliminating dependency on the physical mold book; and the mold buyer, from anywhere in the world, can access critical information on any tools that have been built. Step 3: Mold builder input. Step 4: Check it out. If these steps are followed, surprises inside the mold can be eliminated. "What's In It for Me?"
Those are the benefits. Is there any negative impact? Not really. A proper mold management system can be set up for a minimum cost, so the only negative impact might be that a mold costing $52,100 with unknown steels and components now costs $52,900 with a system in place, for example. Considering the productivity that will be required from that tool, getting what you want should not be seen as an added cost. You're the Customer Whether or not we like this new global market, it is a reality that we all have to contend with. And for tooling engineers, whether a mold is purchased from down the street or across the world, now is the time to review mold specifications and determine how those specifications will be consistently maintained. |
