Goals of this Course:

    • Train production and design personnel to analyze, identify and correct 11 of the most common and costly plastic molded part defects
    • Expand problem-solving capabilities and improve quality
    • Dramatically reduce reject rates
    • Maximize profits through efficient, defect-free scientific molding techniques

    Paulson’s popular online course has a fresh new look with expanded content and includes introductory segments featuring Plastics Pioneer and veteran industry educator Don Paulson. He gives insider information on the cause and effect method of problem analysis. Each lesson will help you learn to recognize and analyze plastic injection molded part defects from a scientific molding point of view. Gain valuable skills in order to solve a variety of production and management problems.

    This course is designed to train production personnel to recognize and analyze injection molded part defects from a scientific molding point of view. The course includes a description of machine control adjustments necessary to correct specific part defects. Includes in-depth explanations of causes and solutions to 11 of the most common molded part problems: Voids, Sink Marks, Short Shots, Flash, Weld (Knit) Lines, Splay (Silver Streaks), Jetting, Burn Marks, Warp, Cracks and Part Breakage, and Controlling Molded Part Dimensions.

    This program teaches injection molders, mold designers and part designers how to identify and correct the most common and costly molded part problems. Part defects are described and analyzed to show how each develops. The machine control adjustments and/or tooling and part design changes necessary to correct specific defects are explained in detail. Also included is an explanation for the cause and effect method of problem analysis – a very valuable technique for analyzing and solving all types of production and management problems.
