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.

Challenge
A consumer unit-dose package with a break point needed to be able to be ejected and sealed.

Solution and Results
A Design for Manufacture and Assembly by the Natech Engineers solved the conflicting challenges.

Challenge
A drug delivery mechanism had a high risk of leakage of the combustible material.

Solution and Results
Natech's Engineers performed a Design for Manufacture and removed one join and improved the two remaining joins.

Challenge
This electronics client had designed a part with excessive ribbing which posed risks during the ejection process.

Solution and Results
The Natech Engineers performed a DFM analysis to reduce the ribbing and maintain the strength and flatness requirements.
