package includes:

• Introduction to Injection Molding 

  This course provides participants with a general introduction to the plastics industry. The primary focus of this training program is the day-to-day operations of a typical injection molding facility.

  An Introduction to Injection Molding was created for newcomers to the injection molding industry or anyone that would like to learn more about plastics. We recommend that new hires take this course before participating in our Injection Molding Basics series.

  • An overview of plastics and the industry
  • A typical molding facility
  • General plant safety
  • An introduction to the molding process
  • Molding machine components
  • Material handling
  • Injection mold terminology
  • Common part defect                                                                                                                                                                                                                                  
• Injection Molding Basics 

  Our Basics series provides participants with a general understanding of the three major aspects of injection molding; the injection molding machine, the molding process, and the injection mold. These programs use 3D animation to demonstrate the inner workings of the machine and mold and to easily convey otherwise complex concepts. Important safety precautions are stressed throughout these training programs.

  These basic injection molding training programs are ideal for new hires, yet also serve as an excellent refresher course for any employee involved in plastics processing; from operators and technicians to management and setup personnel.

  Part 1: Machine

  • Cites important safety precautions for working around injection molding machines
  • Gives an introduction to the injection molding process
  • Introduces machine types and the different modes of operation
  • Discusses injection molding machine components and their respective functions
  • General procedures for starting up and shutting down a molding machine

  Part 2: Process

  • Discusses polymers and the three criteria used to classify them
  • Covers some of the more common procedures for material preparation
  • Introduces the three phases of the molding process; injection, cooling and ejection
  • Explains the need for maintaining an accurate process log
  • Defines common injection molded part defects and explains their causes

  Part 3: Mold

  • Explains the specific functions that an injection mold must perform
  • Introduces the various machining methods used to construct an injection mold
  • Discusses the three mold configurations used in the industry
  • Covers common runner shapes and gate types used in injection molds
  • Gives an overview of proper injection mold maintenance                                                                                                                                                                                     
• Understanding Plastics

  This program explains how and why plastics are different and cites several different types of polymers and processing considerations. Understanding Plastics emphasizes material handling, explains regrind, and covers the effects that moisture can have on molded part properties during processing.

  • The definition of plastics
  • Polymer classification
  • Material properties affected by processing
  • Proper material handling techniques
  • Processing characteristics of virgin and regrind                                                                                                                                                                                     
• Establishing a Scientific Molding Process

  This scientific molding training course provides participants with in-depth processing information to better prepare them for making appropriate and cost-effective decisions when establishing or improving a scientific injection molding process.

  The course teaches a processing strategy that properly decouples 1st stage fill from 2nd stage pack. Students who understand and utilize the strategy described in this course will produce processes with a much higher repeatability. The steps outlined in this course are intended to quickly establish a scientific injection molding process, reduce downtime and improve process efficiency.

  • General Rules for Scientific Processing
  • Scientific Process Optimization Strategies:
    • 1st Stage Filling
    • 1st Stage to 2nd Stage Transfer
    • 2nd Stage Pack
    • Screw Delay
    • Screw Recovery
    • Screw Decompression
    • Cooling Time
    • Mold Opening
    • Part Ejection
    • Mold Closing
    • Clamping
