Challenge
Four of the five component designs had already been defined in relative isolation and were already locked, but tolerances allowed for potential leakage risk during assembly.

Solution and Results
The Natech Engineers performed a tolerance stack analysis and refined the specifications to address the assembly risks.

Challenge
The mold had been designed and build without considering part shrinkage.

Solution and Results
The Natech engineers were able to employ a design of experiments to adjust the process rather than adjust the mold.

Challenge
Size and feature variations to the part would require eleven separate molds.

Solution and Results
Integrating flexibility into the mold design helped the client avoid the costs associated with building a new mold for each variation.

Challenge
Improve the mold design to improve quality and extend mold life

Solution and Results
Improved process control, wider processing window, and reduced cycle time

Challenge
A part designed for machining needed to transition to injection molding.

Solution and Results
The Natech Engineers applied Design for Manufacture to the parts to improve risks and economics.

Challenge
A design for a Collector of blood sample had been designed for manufacture, but posed risks in assembly.

Solution and Results
The Natech Engineers identified and resolved the assembly risks during the design for assembly phase.
