Challenge
A diagnostics application experienced a dimensional change due to a mold cooling change.

Solution and Results
A DOE revealed a counter-intuitive solution.

Challenge
A two-component subassembly with an internal locking mechanism required an undercut.

Solution and Results
The DFM phase reduced the subassembly to a single component and saved over $55,000.

Challenge
The Mold Flow Analysis revealed three primary quality concerns: Gate Freeze, Volumetric Shrinkage, and Warpage.

Solution and Results
Improved quality, cycle time, and cost for a 165% ROI by the end of the first year.

Challenge
A Polystyrene part from a 32-Cavity mold was causing rejects when assembled to an HDPE/LDPE component from a 64-cavity mold.

Solution and Results
Rather than adjust the mating diameters, the Natech Engineers collaborated with partners in the Materials Sciences to find an additive to reduce the surface lubricity.

Challenge
Overmolding can cause substrate deformation and flash.

Solution and Results
Adding sidecam support and interlocking cores to the mold design achieved a consistent wall thickness free of flash or deformation.

Challenge
A thin-walled section posed a high risk of incomplete fill.

Solution and Results
Modeling with mold flow analysis successfully identified the optimized gating to address the racetracking issue.
