Course Overview

In collaboration with ConxusNEO, a driving force in Summit County, Ohio, engaged in workforce development by supporting world-class, demand-driven and data-informed talents, University of Akron (UA) Polymer Training Services (APTS) is offering the INJECTION MOLDING CERTIFICATE PROGRAM (IMCP). For this purpose, we partner with companies, regional and nationwide, to identify the skills they need to thrive, and align with education and economic development of public-sector and community partners to transform the way people are prepared for great careers. Specifically, Northeast Ohio (NEO) local industry as well as the Greater Akron Chamber has emphasized the unmet need for training in injection molding operation and process knowledge and the UA IMCP has been constructed to serve similar needs nationally and worldwide.

The IMCP Program has been designed to impart basic understanding of the process variables and how they impact the part, as well as quality control processes and the ability to troubleshoot the process.

As required for any certificate program, competency tests for each module/course will be administered, and a certificate will be issued upon successful completion of the program.

The IMCP involves one week (8 hours per day) web-based instruction. A quiz is given at the end of each day of instruction to assess participants’ comprehension of the material covered and fill in any perceived weaknesses the following day (until the last day). A comprehensive quiz is administered on the last day of instruction. Such assessment of enrichment is necessary to be able to award a certificate.

The topical coverage for the IMCP can be summarized as follows.
