Case Study: Custom CNC Machined Polycarbonate Guards for Manufacturing Line
Client: Leading Automotive Manufacturer, Queensland
Project: CNC machining of custom Polycarbonate machine guards for a high-speed manufacturing line.
Challenge:
The client needed custom-cut Polycarbonate guards for their manufacturing line to protect workers from moving parts while maintaining visibility. The guards needed to be impact-resistant, precisely cut to fit existing equipment, and provide long-lasting durability in a fast-paced environment.

Solution:
We worked closely with the client to machine Polycarbonate sheets using our CNC technology, ensuring precise cuts and smooth edges. The Polycarbonate material was chosen for its impact resistance and optical clarity, allowing workers to safely monitor the machinery while being protected from moving parts.

Result:
The custom CNC machined guards were installed seamlessly into the manufacturing line, providing improved safety for workers while maintaining the required visibility. The client reported enhanced safety measures and was highly satisfied with the precision and quality of the machined guards.
