Basics of Polymer Testing and Processing Training Course


This course is designed to be an introduction to the rubber industry for employees who have very little or no understanding of how rubber or plastic parts are manufactured and tested. This course introduces some basic terminology used in the rubber and plastic industries. Several types of testing will be introduced and practical examples will be shared to illustrate why parts/products are tested. Lastly, this course provides an overview of the rubber mixing process as well as a few processing and curing methods commonly used in this industry. This presentation will give new employees a big picture view of the different departments within ARDL, will illustrate how those departments work  together and will emphasize why each aspect of our company is so important to the rubber and plastic products that we use every day.
