SUMMARY

The discussion focuses on calculating the highest and lowest temperatures during the injection moulding process involving four different material inserts. The molten plastic is injected into these inserts for approximately 22 seconds before ejection, and the user seeks assistance in defining the temperature curves over time (T on t). Initial calculations yielded unexpectedly high results, prompting the request for further guidance on this specific thermal analysis.

PREREQUISITES
  • Understanding of injection moulding processes
  • Knowledge of thermal dynamics in plastics
  • Familiarity with temperature measurement techniques
  • Basic skills in data analysis and curve plotting
NEXT STEPS
  • Research thermal properties of different plastics used in injection moulding
  • Learn about temperature profiling in injection moulding cycles
  • Explore software tools for simulating thermal dynamics, such as Autodesk Moldflow
  • Investigate methods for accurate temperature measurement during the injection process
USEFUL FOR

Engineers and technicians involved in injection moulding, materials scientists, and anyone interested in optimizing thermal processes in manufacturing.

Hi everyone I am looking for someone who could possibly help me with my calculations regarding injection moulding. Basically I have four different inserts (from four different materials). Into these inserts the molten plastic is injected, where stays for about 22 seconds and then is ejected, then the cycle repeats. I am trying to define what will be the highest and lowest temperature during these cycles, basically I need to calculate and define the process of temperatures(curves) T on the t.

If anyone would know and will be able to spend some time I would really appreciate it. I will then provide you with all information I know. I already calculated (with help of my friend) this issue but results were really high.
Please looking for any help.

thanks
