Injection Molding Fundamentals is a new two lesson 3-4 hour training program that teaches your personnel the most important and fundamental aspects of the injection molding production floor and molding process. Using state-of-the-art 3D animations, participants get a firm understanding of the inside the injection molding process. The course also uses actual in-plant scenes so that employees and prospective employees gain an understanding of typical production floor operations.

3 4 Hours of Training

Safety around the injection molding production floor and machinery is emphasized throughout these lessons. The emphasis is on production efficiency, safety and teamwork. The course also extensively covers the fast and accurate identification of part defects.

Give all your new employees a firm, common foundation from which to build their injection molding knowledge and give your current employees refresher training with Injection Molding Fundamentals. This course serves as excellent refresher training for veteran employees.

Lessons Included

Lesson 1: Parts of the Molding Machine and Operator Responsibilities

This lesson starts with an overview of the injection molding process, machine part identification and standard operator responsibilities during the molding cycle, modes of operation of the machine and the important aspects of material handling, Emphasis is given to operating safety, protection of molds from damage, and proper plastic part handling.

Lesson 2: Identifying Part Defects and Safety

This lesson presents visual and animated 3D examples of all of the most common injection molded part defects such as short shots, flash, warp, surface defects and color changes. It also discusses secondary operations such as regrinding, trimming flash and de-gating plastic parts from runners. Employees are taught to identify common part defects such as short shots, flash, warp, surface defects and color changes.


Practical Injection Molding is a comprehensive 15 CD-ROM program (over 40 hours of training) focused on developing the skills and understanding your personnel need in your injection molding facility. In addition to 15 interactive lessons, Practical Injection Molding features SkillBuilder, which is a revolutionary new training platform for injection molders. SkillBuilder is an injection molding machine simulator combined with interactive molding labs which allows your employees to gain real, hands on molding experience before running the molding machines on your production floor. Combined, this comprehensive interactive training series and SkillBuilder package is unmatched by any training program in the plastics industry. Molders from around the world see dramatic results in productivity and profitability from this program and rely on it as the foundation of their training and troubleshooting program.

Practical Injection Molding contains four core modules and is recommended for anyone involved in the injection molding process.

PIM Module 1 - Basic Injection Molding

The Basic Injection Molding module contains five CD-ROM lessons (over 20 hours of training). This hands-on, interactive package is recommended for machine operators, material handlers, set-up personnel and production supervisors. The Basic module focuses on the fundamentals of injection molding technology, including basic knowledge that all personnel involved in the molding process must understand to make informed decisions on the production floor.

Note: Price includes five CD lessons, comprehensive leaders guide and five study guides.

Detailed Lesson Descriptions for Basic Injection Molding

Lesson 1 Inside the Molding Machine Shows and describes all major components of the injection molding machine.

Lesson 2 Inside the Mold Construction and operation of two-plate, three-plate and

runnerless molds.

Lesson 3 The Nature of Plastics Characteristics, types, structure, size and processing behavior.

Lesson 4 Machine Operating Controls Part 1 - Purpose, operation and effects of the pressure and fill rate controls.

Lesson 5 Machine Operating Controls Part 2 Purpose, operation and effects of machine and mold temperatures, timers, screw and clamp controls.

SkillBuilder For PIM Basic Module 1

SkillBuilder is the molding lab portion of our training. It integrates a fully functional injection molding machine simulator with fifteen structured lab lessons. This closes the loop on employee training by allowing employees to immediately apply what they learn in the interactive lessons. Detailed Lab Lesson Descriptions for SkillBuilder

Lab Lesson 1 Understanding the Injection Molding Process A review of the sequence of the standard injection molding cycle with emphasis on timer operation.

Lab Lesson 2 Setting Machine Controls Learn how to operate the control panel of the molding simulator and how to interpret SkillBuilder outputs like fill time, cycle time, melt temperature, part size and part weight.

Lab Lesson 3 Understanding Fill Rate Controls Teaches the effects of setting SkillBuilders five steps fill rate profile on cavity fill time and part characteristics.

Lab Lesson 4 The Effects of Back Pressure Examines how raising and lowering the back pressure setting affects the melt temperature and the maximum allowable back pressure setting and the effects of exceeding it.

Lab Lesson 5 Setting the Injection Limit Timer Learn the proper setting for the injection limit timer, which shuts off the injection pressure if the VPT set point is not reached.

Lab Lesson 6 The Maximum Injection Pressure Settings Discusses how to set the maximum injection pressure setting so the fill rate control never lacks the pressure it needs to fill the cavity according to the fill rate profile.

Lab Lesson 7 Setting the Holding Timer Examines how the holding timer determines the length of time the holding (second stage) pressure stays on. Lesson 7 also examines the effects of the holding time on gate sealing and molded part weight and dimensions.

Lab Lesson 8 Setting the Holding Pressure Focuses on how to set various holding pressures to determine the effect on the molded part weight and length.

Lab Lesson 9 Mold Closed Time and Mold Open Time vs. Melt Temperature Learn the effects of mold closed and open time on the melt temperature. Set the mold-closed time to the minimum required to make a good part.

Lab Lesson 10 The Effects of Barrel Zone Temperatures on the Melt Temperature Vary the temperature setting of each barrel zone temperature, one at a time, to determine how each zone affects the melt temperature. Learn how to match the actual melt temperature to the front zone barrel setting; a good molding practice.

Lab Lesson 11 Some Effects on Mold Temperature Set different core and cavity mold temperatures to determine the effect on peak cavity pressure and part dimensions.

Lab Lesson 12 The Effects of Screw RPM Learn by setting various screw rpms, the effects on the melt temperature and the plasticating time (the time required to convey the next shot of plastic ahead of the screw.)

Lab Lesson 13 The Effect of the Screw Back Position Examines the effects of the screw back setting on the cushion size and on the melt temperature. Students can change the screw back position to increase and decrease the cushion size.

Lab Lesson 14 Effects of Clamp Force Learn how the molding conditions affect the amount of clamp force required and how to set the clamp force to the minimum required to produce a good part.

Lab Lesson 15 Achieving and Controlling the Melt Temperature Use knowledge gained in previous lessons to accurately achieve a desired melt temperature. Learn the front zone barrel temperature and the melt temperature often dont match and examine the various machine controls available to alter the melt temperature.

PIM Module 2 Expert Series
