Overview

The seminar provides an overview of the use of simulation for thermoplastic injection molding. Classroom lectures cover the basics of simulation, model preparation, results analysis, and interpretation. The Attendees will gain an understanding of the role of simulation for product design, mold design, and processing. Hands-on workshops provide practical examples of simulation and injection molding processing. The following learning objectives have been defined for this seminar:

  1. Understand the use of injection molding simulation for plastic part and mold design.
  2. Develop awareness of simulation reliability and comparison to real manufacturing data.
  3. Practice simulation procedures to understand possibilities and limitations.

Audience

The course is appropriate for product designers and engineers, industrial designers and engineers, mechanical engineers, process engineers, and anyone involved in plastic part or mold design and procurement.

Content

  • INTRODUCTION: overview of the injection molding process, the role of simulation.
  • SIMULATION SETUP: model preparation, meshing, material database, cooling system design, feed system design.
  • RESULTS INTERPRETATION: fill, pack, cool, warpage, results interpretation.
  • FLOW BALANCING: part design, mold design, filling imbalances, shear unbalancing, gating, feed system design, shear flow.
  • COOLING ANALYSIS: cooling system design, cooling efficiency, conformal cooling.
  • WARPAGE AND DESIGN OF EXPERIMENT: analysis of factors impacting warpage, such as design, material, and processing.
  • SIMULATION ACCURACY: comparison with experiments, pressure discrepancies, analysis of the effects of material, mold design, part design, process parameters, heat transfer, flow behavior.

Workshops

In simulation and experimental workshops attendees will explore and practice the lecture topics. During the seminar, each attendee will have access to simulation software. The attendees also will use injection molding machines with instrumented and non-instrumented molds.

About The Instructors

Dr. Davide Masato received a B.S. in Mechanical Engineering (2011), an M.S. in Mechanical Engineering (2014) and a Ph.D. (2018) from the University of Padova in Italy. In 2016, he was a visiting researcher at the University of Bradford (UK), where he worked at the Centre for Polymer Micro and Nano Technology (Polymer MNT). Prior to joining the faculty at UMass Lowell, he was a post-doc researcher at the University of Padova, where he worked at the Te.Si. Laboratory for Precision Engineering and Manufacturing. Since 2018, Dr. Masato has been an Assistant Professor in the Department of Plastics Engineering at UMass Lowell. Dr. Masato teaches undergraduate and graduate engineering design, injection mold design, and computer-aided engineering classes. His research focuses on plastic product design, polymer processing technologies, sustainable manufacturing, and computer-aided engineering. Dr. Masato's research resulted in 35+ journal publications, 50+ conference presentations, 1 book chapter, and 3 patents.

Srikar Vallury is the Engineering Manager at Moldex3D. He graduated with a Masters degree in Mechanical Engineering from Oregon State University and then, moved to Michigan for his first job in the automotive industry. In 2013, Vallury made the transition to the plastics side when he joined Moldex3D and immediately fell in love with his job. As an engineer, he spends his time helping designers / engineers visualize and resolve their design or manufacturing issues through simulations. Being a strong advocate of simulation, Vallury focuses his efforts on ensuring the software application meets expectations of the industry / user community.
