NADCA - Die Casting Operator Training Webinar Series

Posted by Hill and Griffith Company on Feb 20, 2019 3:12:39 PM

The die casting industry depends on the skill of the machine operator for efficient production of high-quality products.

The effective machine operator understands the basic function of the process, the proper care of the die casting machine, die setup, recognition and control of basic casting defects, and the procedures that ensure his/her personal safety.

The North American Die Casting Association has created an eleven part webinar series geared towards educating operators on the do's and don'ts of running a die casting machine. Signing up for all eleven parts of this series will also grant you access to these courses through the NADCA Online Education System, which allows you to view the recordings, pdf's and support material for a full year.
