Innovative Solutions for Unique Tooling
Bridging the gap between physical replication and dynamic facility automation. In a strategic design program with Unique Tooling Pty Ltd, our team deployed precision 3D scanning reverse engineering and engineered a state-of-the-art, food-grade pick-and-place blow moulding automation system. These integrated solutions successfully reduced plant downtime, slashed supplier dependencies, and secured a clean, contamination-free handling environment ready for production scales.
Executive Summary
project profile & parametersModern precision manufacturing demands complete operational autonomy and rapid turnarounds to survive supply chain volatility. Our engineering engagement with Unique Tooling Pty Ltd tackled two distinct operational bottlenecks. First, we resolved high tooling lead times and external supply dependencies by deploying high-resolution 3D scanning to reverse engineer complex tooling components into fully parametric, fabrication-ready CAD models. Second, we transformed manual, high-risk handling at the blow moulding stations into a hygienic, robotic pick-and-place automation layout. The resulting designs achieved food-grade compliance, maximized worker safety, and yielded massive cost-efficiencies, proving the power of data-driven industrial integration.
Eliminate reliance on third-party fabricators. Digital capture of physical metrology combined with standardized robotic paths guarantees permanent, repeatable in-house production.
- Generate parametric CAD layouts to print or machine replacement tools in-house.

Frequently Asked Questions
clarifying the design choicesHow accurate is the 3D scanning metrology used for reverse engineering?
Our high-precision scanners capture physical tooling surfaces down to a resolution of 0.02mm, ensuring reconstructed parametric models match original parts perfectly.
Why choose parametric CAD rebuilding over standard point-mesh models?
Raw point meshes cannot be easily edited. Rebuilding parts with parametric parameters allows engineers to modify dimensions, adjust holes, and update drawings instantly in SolidWorks.
What materials are specified for the food-grade robot grippers?
We specify premium FDA-compliant polymers and high-grade 316 stainless steel with polished surfaces to prevent bacterial growth and withstand aggressive chemical washes.
How does the robotic arm synchronize with the blow moulding machine?
The robot's controller is linked directly to the blow machine's PLC. It reads physical limit switch signals, entering the mold cavity only when doors are confirmed fully open.
What safety measures protect operators near the running robot?
We integrated electronic safety light curtains and physical interlock gates around the robotic zone. Breaking the light path stops robot movement instantly to prevent injuries.
What were Graham Lee and Daniel Kohoutek's contributions to this project?
As Unique Tooling's leadership team, they provided vital feedback on workshop machining limits and mold cycles, ensuring our designs matched their production floor capabilities.
