Thermo Polyurathane Injection Moulding - TPU barrel life test

Click For Summary
SUMMARY

The discussion focuses on testing the impact of prolonged exposure of Thermo Polyurethane (TPU) in the heated barrel of injection moulding machines on the quality of TPU screen filters used in the mining industry. The testing method involves assessing the TPU material after it has been subjected to downtime periods ranging from 15 minutes to an hour. Feedback is sought on the preliminary method for casting test samples to ensure accurate results. The inquiry highlights the importance of understanding how idle time affects TPU properties during the manufacturing process.

PREREQUISITES
  • Understanding of Thermo Polyurethane (TPU) properties
  • Familiarity with injection moulding processes
  • Knowledge of quality assurance testing methods

I work at a company that manufactures TPU screen filters for the mining industry. I've got a test to do to inspect whether the qaulity of the TPU is affected by time in the heated barrel of the injection moulding machine. The TPU material sits in the barrel due to tea and lunch breaks (15 - 30 minutes), also through maintenance and shift change (up to an hour downtime for maintenance). Attatched is my preliminary method for casting my test samples. If anyone could just have a look at it and give me feedback, it would be highly appreciated.
