The workshop would describe the most common root causes for high discharge temperatures, rate limitations, flow surging, resin degradation, color mixing problems, and melting limitations to name just a few, Once the root causes are identified, technical solutions will be provided. All troubleshooting problems will be described using actual field case studies and the remedies used to eliminate the problem.
