Process Control: From Rotolog to ‘Hands-Free’ Rotomolding Control

The basics of process control for rotational molding have now been well established and their use continues to grow as machines and final product demands become more critical. This course covers the essential elements of process control, the systems available and the knowledge can be applied for best advantage. Some of the areas covered include:

Optimizing material properties – defining the process window for rotomolding
Controlling final product quality in terms of strength and dimensions
Balancing production cycles
Adjusting processes for changes in ambient (seasonal) conditions
Process control systems from all the various suppliers worldwide
Latest non-contact thermometry in the IRT system from Ferry Industries, Inc.
How to use IRT for ‘hands-free’ rotomolding
Correlating IRT with Rotolog and managing production and part dimensions

Duration: This is a half-day seminar with around 3-4 hours of instruction.

Group Size: Ideal group is 7-12 people for best interaction. Larger groups can be accommodated (up to 20 or more) if required but interaction will be reduced.
