Online Webinars

NADCA offers a variety of options to address all of your educational needs.  Some of NADCA’s most popular education option are Webinars. 

Webinars are live web broadcasts presented weekly.  Attending a webinar is an excellent way to obtain vital information without the hassle or cost of travel.  Topics for webinars include, but are not limited to Safety, Results of Surveys and Studies, Various Processes, Economic Industry Data, NADCA R&D Research Results and New Technologies. A webinar presentation will not only address important information on the topic but also provide adequate time for questions, answers and discussion.

Below you will find a schedule of  Webinars.

    PQ2: Bernoulli’s Equation 11/28/2017 Continuing from the PQ2 Overview this course looks at the requirements and math behind the PQ2 tool. Specifically, how Bernoulli’s equation relates the requirements and process parameters to pressure and flow rate. This course will allow a die cast engineer to create a PQ2 graph for a casting and machine. Add to Calendar

    PQ2: The Gating Equation 11/29/2017 Continuing from PQ2 Bernoulli’s Equation this course introduces The Gating Equation. Revised by Professor Al Miller in 2015, The Gating Equation uses the basic physical properties of the alloy and process to calculate the time it takes for the metal to solidify in the die cavity. This allows the optimal gate area to be calculated for the casting. This will be a detailed look at where the inputs come from and the steps to work through The Gating Equation. Add to Calendar

    Gating: Overview 12/12/2017 Gates and runners determine how quickly metal enters the cavity and how it flows. This session will introduce the concept of gating design. It will take a look at how to select a location for the gate(s), how to break a complex cavity into zones, and how to distribute the gate area. It will also look at general flow patterns from fan and tangent gates. Math will be kept to a minimum. Add to Calendar

    Gating: Metal In, Air Out 12/13/2017 Metal is pushed from the shot sleeve or nozzle through the runner or sprue and into the cavity. To prevent air from getting trapped in the metal the runner system needs to be properly designed and outgates, overflows, and vents need to be sufficient and correctly placed. This session will look at designing a runner system, sizing the gate (utilizing the atomization equation), and placing and sizing of outgates, overflows, and vents. Add to Calendar

    Gating: Runner Geometry Construction 12/14/2017 Runner geometry controls the angle at which the metal flows through the gate. It also prevents metal flow from becoming turbulent and trapping air. Building off the Gating: Overview and Gating: Metal In, Air Out this session will review the equations used to design the runner geometry of fan and tangent gates. A basic understanding of trigonometric functions is recommended. Add to Calendar
