A moldmaker likes a challenge, and that is what was received when A-1 Tool Company (Melrose Park, IL) was approached by a West Coast container manufact-urer. The molder had been manufacturing a product for some time and had many molds used for its production, but now there was a desire to alter the molds in order to reduce the part weight due to the rising cost of the plastic material.
Mike Schillaci, Vice President of Sales, related that this customer had previously tried to reduce the wall stock using the current mold design and gating by just reducing the wall thickness of the part. The customer invested time and money on the effort only to see it fail due to flow length. That’s when the customer turned to A-1 Tool.
Having already worked with similar projects, the A-1 team knew that although its customer’s original request for help working with existing tooling was not an impossible one, another approach was viable and so they presented a new solution.
“With this project, we began by looking at aspects including those our customer may not have considered,” explains Schillaci. “With every project, we try to meet with customers early on so that we can influence the part design. Our sales personnel have the experience and skills needed to warn of such things as bad steel condition, drafts needed for textures and changes that could make secondary labor less intense and costly.”
Schillaci and A-1 Tool’s President Geoff Luther met with the customer and reviewed the problem, and then proposed building a new tool—though that was not the original customer request. Questions that were asked:
“We quoted options on design elements that could influence any tests or shipping requirements they may run into,” Schillaci says.
For example, the thinner wall could fail a drop test, so design options were quoted, such as structural ribbing or reshaping the bottom of the container—changes that could be made with minimal influence on the tool and the customer’s budget.
“Upon initial sampling, if the product doesn’t pass every test, the options we quoted are already budgeted for and therefore can be implemented quickly,” he explains.
Because the original tool could not be effectively altered and saved for production, A-1 Tool’s new approach, given the savings gained over the life of the mold, made the investment in a new tool a savvy financial decision for the customer.
A-1 Tool was able to do the math for its customer (see sidebar) on this project to prove out the savings gained
by implementing a new mold build and these were the results:
“We offered contingencies and provided tangible data that could be taken back to management to justify the idea of not only building a new mold, but for building a better one,” states Luther.
There is nothing more costly than a tool that doesn’t perform to its maximum potential. Producing the lowest cost part is the whole reason a tool is built. Challenging traditional approaches of the past is an opportunity for profitability on the part of both the moldmaker and the customer.
