Intended Performance Outcomes
Upon successful completion of this course you will be better prepared to:
- Know how to set up an injection molding machine for accurate responses.
- Know how to remove moisture from the plastic pellets.
- Identify the time it takes for the machine to complete a cycle and why.
- Know how to properly develop an optimum fill time.
- Recognize the many disadvantages to using a high injection pressure.
- Recognize that the higher the screw speed, the higher the melt temperature.
- Recognize that back pressure can degrade materials with low heat stability.
- Know to set the barrel temperatures to the lowest recommended settings.
- Recognize that packing pressure is used to compensate for shrinkage.
- Know how to use part weight to determine the packing time.
- Recognize that cooling time is greatly dependent on the mold temperature.
- Recognize that the final portion of the cycle is the removal of the part.
- Recognize that changes in room temperature will change the rate of cooling.
- Be aware that the electrical supply to the machine must be checked regularly.
- Recognize the importance of monitoring and documenting each process.
