The workshop addresses 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.

Why Should You Attend?

Process engineers responsible for designing and optimizing extrusion processes who want to enhance troubleshooting skills. Professionals responsible for the maintenance and repair of single-screw extruders seeking in-depth knowledge to diagnose and fix problems efficiently. Production managers overseeing extrusion operations who want to improve overall efficiency and reduce downtime by addressing issues promptly. Professionals responsible for ensuring the quality of extruded products, as troubleshooting skills are essential for maintaining product quality. Those working in the broader plastics industry who want to deepen their understanding of extrusion processes and troubleshooting techniques.


Mark Spalding

About the Instructor

Mark A. Spalding is a Fellow in PE Product Research and Development in Midland, MI. He joined Dow in 1985 after completing a BS from The University of Toledo and a MS and Ph.D. from Purdue University, all in Chemical Engineering. He has performed fundamental research in single-screw extrusion, developed methods to measure resin physical properties that are important to polymer processing, developed numerous techniques to troubleshoot and increase the rates of extrusion lines, and has developed new mathematical models for extrusion simulation. He has designed and troubleshot numerous extrusion lines for Dow and for resin customers. Mark led rate increase projects for numerous PE production plants that were rate limited by the finishing section of the plant. He was instrumental in doubling the rates of many foam lines and fiber lines by applying fundamental technologies. Early in his career, he developed diagnostic techniques to determine the root causes of flow surging for many styrenic resins, and then redesigned the process to eliminate the surging. He has developed a screw deign protocol for mitigating gels in PE film lines. Many Dow resin customers have benefitted by using these techniques to optimize their extruders for rate and quality. He has authored 398 CRI reports and 157 outside publications. Mark coauthored the book “Analyzing and Troubleshooting Single-Screw Extruders” with Gregory A. Campbell, and is the editor of the “Handbook of Industrial Polyethylene and Technology.” He is a Fellow and Honored Service Member of SPE, a current member of the Extrusion Division Board of Directors. He was awarded the Bruce Maddock Award in 2006 for his contributions to the industry in single-screw extrusion, and the SPE Research and Engineering Award in 2019. He has won Best Paper awards in the SPE Extrusion and Injection Molding Divisions 10 times.
