    Gating & PQ² - Calculations 04/05/2023 In this session uses the ideas introduced in the first two sessions to calculate total gate area requirements by first introducing and demonstrating how to calculate the optimum gate area by computing the maximum fill time. This leads directly to calculation of the gate area that maximizes the operating window. The standard atomization calculation to check gate dimensions is illustrated. The use of the NADCA web app to complete these calculations is also briefly illustrated. Add to Calendar

    Gating & PQ² - Designing Runners, Overflows and Vents 04/06/2023 This session addresses construction of the detailed geometry of runners and gates. Cavity layout is briefly discussed followed by main runner geometry construction, with consideration both of heat loss and fluid flow. Procedures to construct tangential and fan gates are introduced along with guidelines for constructing overflows and vents. Use of the NADCA web app to complete these calculations is illustrated. The session concludes with a very brief introduction to the importance of simulation for design evaluation and verification. Add to Calendar
