New MoldTru™ LPT-68000 low-profile tooling resin from AOC can reduce the cost and time to make Class A surface composite tools by up to 70%. The new resin is designed to make tools for open molding, resin transfer molding and resin infusion.

"Because MoldTru LPT-68000 resin's unique chemistry produces very low exotherm heat, up to five layers of tooling laminate can be built simultaneously without causing surface distortion," explained AOC Business Manager Fletcher Lindberg.

"Making the same mold with conventional tooling resin takes five individual steps, each followed by an overnight cure," he continued. "With MoldTru LPT-68000 technology, all that extra labor is eliminated, and finished parts are going out the door much sooner."

Replicating the master model

AOC chemists leveraged the company's leadership in automotive Class A resins to engineer a special additive technology that gives the new tooling resin a near-zero shrink feature. Ultralow shrinkage combines with excellent fiber and filler wetting to ensure that the mold surface is essentially a precise replica of the master model's surface. For some applications, vacuum can be used to produce high glass content tooling with technical fabrics.
