Approximately 20 hours of interactive training in three injection molding process modules: Module 1 (for Operators), Module 2 (for Technicians) and Module 3 (Advanced).

DIL’s Interactive Universal Molding™ training program for Windows includes the following:

Module 1 (MU™ for Operators):

MU1 – Introduction – an introduction to injection molding process and the discipline of Universal Molding™

 

MU2 – Fundamentals – explains Universal parameter contributions and how they relate to machine parameters

 

MU3 – Molding with Graphs – explains the importance of the injection process graphs and how to interpret them

 

MU4 – Plastic Morphology – discusses the basic types of plastics and how their characteristics differ during the molding process

 

Mixing and Blending Plastic Resins – explains various aspects of mixing and blending, including the different machine options and sizing calculations.

Module 2 (MU™ for Technicians):

MU5 – Press Calculations – discusses clamping force and its determination, platen sizing, and its operation.

 

MU6 – Injection Unit Calculations – explains such items as determining shot size, nozzle tips and sprue bushings selection, specific density, injection flow, barrel utilization, and temperature profiles, among other topics.

 

MU7 – Cooling Calculations – includes information on calculating cooling demand, the use of chillers and cooling towers, cooling time approximation, and how temperature control units (TCUs) work.

 

Drying Hygroscopic Materials – explains material drying fundamentals, how to size a drying system, and drying equipment configurations.

Module 3 (Advanced MU™):

MU8 – Machine Rheology – discusses various aspects of plastic melt flow, shear stress, viscosity, conventional rheology and rheology by power, and how to predict injection time.

 

MU9 – Determining Injection Speed – reviews the data and calculations needed in order to determine the optimal molding parameters, and explains how to determine ideal injection time and injection speed.

MU10 – Verifying Fill Balance – discusses the effects of injection time on fill balance in molds with multiple cavities, fill balance analysis, and mold balancing with hot and cold runners.

 

MU11 – Determining Hold Stage Parameters – reviews holding stage and demonstrates how to determine the hold pressure and hold time.

 

MU12 – Determining Cooling Stage Parameters – reviews cooling and recovery, and explains what factors affect cooling and how to optimize the mold temperature and cooling time.

The modules included quizzes for certification, handouts (.pdf files), and a password-protected administrator program to verify student’s progress and to print certificates.
