From Napkin Sketch to Precision: The Power of CAD in Product Development
News
MAY 2025
Every great product begins with a spark of inspiration: sometimes a quick doodle on a café napkin, sometimes a scribble on a workshop bench. But taking that raw idea straight to manufacturing can be a costly gamble. Without a structured design process, even the most brilliant concepts can suffer from expensive errors, delays, or limitations in functionality.
This is where Computer-Aided Design (CAD) changes the game. At Quantech Design, we use CAD not just as a drawing tool, but as the backbone of our development process, ensuring your ideas are refined, tested, and ready for real-world production.
Turning concepts into workable solutions.
One standout example is our work with Coolamon on the award-winning Spreader Chaser Bin. The challenge was to create a single machine that could efficiently spread fertiliser and manage grain loads during harvest, with a customer already waiting for delivery before the design even existed. Using advanced CAD, we rapidly developed a fully integrated model combining the functions of a chaser bin and a spreader.
Through precision modelling, stress simulations, and interference checks, we minimised production risks and reduced the need for on-site modifications. The result was a versatile, safe, and high-performing agricultural machine that went from concept to fabrication-ready drawings in record time, ultimately winning Machine of the Year at the 2019 Henty Field Days.
Another example is our long-term collaboration with Trout River Industries to create a highly adaptable Chip Spreader for road construction. The goal was to combine the best features on the market with new innovations, including adjustable spreading width, segmented control, quick attachment, and robustness for handling abrasive aggregate. Over several design iterations, we optimised the door mechanism, introduced hydraulically driven augers for better material distribution, and refined the control system for precision spreading. Today, these chip spreaders are used across Australia and New Zealand, proving their efficiency and durability in demanding roadworks.
The advantage of engineering precision.
Napkin sketches capture creativity, but CAD captures reality. With advanced modelling, we can:
-
Produce designs accurate to fractions of a millimetre.
-
Simulate stresses, loads, and wear over time.
-
Detect interference or assembly issues before they cost you money.
-
Designing for manufacturing success
Our team doesn’t just design for appearance, we design for manufacturability. We ensure materials, processes, and tolerances align with your production capabilities and budget, whether you’re prototyping one unit or scaling for mass production.
From concept sketch to production-ready model, Quantech Design bridges the gap between imagination and reality. If you’re ready to innovate, test multiple concepts, or bring a fresh idea to market with confidence, we’re the engineering partner that can make it happen.
