Solidification, fluid-flow, heat transfer and modulus<br />
theory are the general principles of the course. Feed bar<br />
sizing as a result of solidification flow patterns, gate size<br />
and design based on fluid dynamics are incorporated<br />
into this practical hands-on course.<br />
Course Location details and hotel group rate will be<br />
provided upon registration. Room block release date is<br />
2 weeks prior to course.<br />
Course Instructor:<br />
Mark Nagel, Director of Education,<br />
Cast Metals Institute<br />
Bring along to course if available: wax patterns/<br />
scrap castings and parts that have gating<br />
problems. You will need a calculator to work the<br />
Gating System Calculations.<br />
Continuing Education: Upon successful completion of the<br />
course, CMI students will receive a certificate awarding 1.1<br />
CEUs. The CEU (Continuing Education Unit) is a nationally<br />
recognized unit of measure for continuing education and training<br />
programs that meet certain criteria.<br />
Tax Deduction of Expenses: An income tax deduction is allowed<br />
for expenses of education (including registration fee,<br />
travel, meals and lodging) undertaken to maintain and improve<br />
professional skills. (See U.S. Treas. Regulation 1.162.5.)<br />
