Description
Compression molding is one of the earliest forms of molding. It is typically used for thermoset materials, but can be used with thermoplastics. The advantages of compression molding include more isotropic fiber distribution, dimensional stability, and surface finish. Compression molding can also support large part sizes, and it has a tendency to produce fewer knit lines. Injection-compression molding is a combination of injection and compression molding. The process keeps the advantages of injection molding and combines them with the advantages of compression molding. In this class, we highlight the advantages and limitations of both processes. We also discuss, in detail, the implementation of the processes using Autodesk® Simulation Moldflow® Insight software.

- TGTowfiq GangjeeDr. Towfiq Gangjee is an Engineering Fellow with Schneider Electric, a global specialist in energy management, with solutions for power distribution, automation and control. He works in the Core Technology Group in Raleigh, North Carolina. Dr. Gangjee has a Ph.D. in Engineering Mechanics from Clemson University and has been with the company for over 20 years. Prior to that, he worked as a CAE Analyst at Becton Dickinson, a global medical technology company.At Schneider Electric, he specializes in Moldflow Analysis of the Injection Molding process using both Thermoplastic and Thermoset polymers. He is primarily involved in helping design plastic parts and molds to ensure manufacturability and pursuing Advanced Research and Development topics in the field of polymer simulation. Recently, Dr. Gangjee has been working with Autodesk Moldflow in providing his expertise and support in the development of Thermoset Injection-Compression and Compression molding simulation software..
David AstburyDavid Astbury has over 30 years’ experience in the fields of rheology, injection molding, software development, and quality assurance. He is the principle author of many optimization technologies within the Autodesk Moldflow software suite, including automatic injection time, molding window, design of experiments, runner sizing and balancing, gate location optimization, and process optimization. Recognising that to fully maximise part quality and to optimise cycle time for an injection mold you cannot look at only the filling and packing phases; you need to also look at the cooling phase as well optimal cooling line placement is critical is a key component of this. David and a team of engineers are currently developing software to automaticaly place and optimise cooling channels within the mold David is an expert programmer and Autodesk Moldflow API expert, and has produced many API scripts and examples to assist customers with integrating to external structural and optimization systems, producing custom results and reports, automating common tasks and extending the capabilities of the system. David has recently worked with the Fusion Generative team to enhance the capabilites and performance of the generative structural software and laying down the foundations for a generative fluids simulation.
