Chief Engineer, Advanced Engineering
Ryobi Die Casting, USA
Dr. Huang is currently Chief Engineer at Ryobi Die Casting, USA. He is responsible for: all R&D activities to drive future profitable growth for the business; assessment, planning, & execution of the manufacturing technology roadmap & setting the technology direction; implementation of new and improved technologies into the operational groups; engineering leadership of technical team that consists of engineers from different departments; supervision and/or execution of concurrent up-front CAE (Computer Aided Engineering) work; technical relationship with customer contact to develop trust and reliable partnerships; help to determine new business opportunities with regard to overall feasibility and profitability; and preparation of highly technical presentations for high profile programs. Before Chief Engineer position, he was a Senior Technical Leader, responsible for development and implementation of new and improved manufacturing processes into operational groups to drive future profitable growth by leading inter-departmental technical projects. His expertise includes manufacturing process simulations with CFD and FEA, die casting manufacturing and additive manufacturing. He is a problem solver with strong engineering background and extensive industrial experiences.
Prior to Ryobi he had worked for Exco Engineering as a head of CAE & Simulations. His work covered the conceptual design of die casting die system, process development and new technology exploration, which includes flow analysis CFD simulation, thermal analysis CFD simulation/thermal inspection, structural FEA & optimization, fatigue analysis and beyond. At Exco he developed a practical Concurrent CAE (Multi-level Simulations) Approach for die casting die system design from up-front casting engineering, tooling key parametric design & optimization to die casting process optimization, which makes the simulation-driven engineering a reality and significantly improves product development efficiency and quality. He also presented a systematic analysis & design method of Vacuum Die Casting Process for Structural Components, which has been widely accepted in the industry.
Dr. Changhua (Joshua) Huang earned his Ph.D. and M.S. degree in mechanical engineering from The State Key Lab of Mechanical Transmission, Chongqing University, China. He received his B.S. degree in Mechanical Engineering (with specialty in Off-Road Vehicle Engineering) from ChangAn University, China. In 1993 his career started as an associate professor at Tsinghua University with research interests in mechanical system design, tribological design, computational mechanics, biomechanical system and rehabilitation engineering. He has published over 30 technical papers, two patents and co-authored one book. In 2014 he received The Best Paper Award by NADCA (North America Die Casting Association).
He is a member of NAFEMS Americas Steering Committee, one of founding members of NAFEMS Manufacturing Process Simulation Working Group and a member of the NADCA Computer Modeling Working Group. He has also been providing professional volunteer services for many years for several international Journals such as reviewer of International Journal of Metalcasting and reviewer of Journal of Materials Processing Technology.
