The document discusses a lightweight technology for injection moulding that uses water to foam polymers during the process, resulting in reduced weight, costs, cycle times, and energy consumption. It highlights the benefits of maintaining recyclability, being a low-cost retrofitting solution, and not requiring changes to existing moulds. The system produces foam in the nozzle only when the machine is running, ensuring that the raw material remains uncontaminated.

1. Light weighting Technology for
Injection Moulding

2.  A retro fit system that uses water to foam
the polymer in the nozzle during the
injection moulding process

3. Benefits
• Reduces weight and polymer cost in the moulded item
• Reduces cycle times and energy consumption.
• Reduces plastic weights into waste streams and landfill.
• Maintains recyclability – no contamination by the
blowing agent - just water.

4. Energy & cycle time savings

5. What about Strength

6. How is it better or different to its competitors?
• Produces foam in the nozzle only, one shot at a
time and only when the machine is running.
• Material within the hopper and barrel remain virgin.
• Only uses water to create the foam.
• Low cost true retro fit system- easy to install,
operate and transfer to other moulding machines.
• Uses existing moulds no changes needed
