About Course

This course offers an in-depth exploration of the world of plastics processing, focusing on the heart of the process: the mold. Participants will learn to conceptualize, use the necessary design tools, and validate injection molds that not only produce high-quality parts but also optimize cycle times and reduce waste.

From steel selection to the design of complex cooling and ejection systems, this program covers the technical pillars necessary to master modern plastics manufacturing.

Upon completing this course, you will be able to:
Analyze the material-mold interaction: Understand how plastic morphology affects cavity filling and the final performance of the part in your mold.
Master mold nomenclature and architecture: Identify all standardized components and hot runner system elements in a mold.
Apply rheology to mold design: Calculate flow behavior in specific mold sections (channels, gates) and for material substitution.
Perform fundamental mold calculations:
Calculate the required clamping force.
Size the cooling system and its energy consumption.
Design and calculate advanced filling systems:
Design sprues, cold runners, and conventional gates.
Apply the rules for hot runner systems, calculating their power requirements and thermal expansion.
Analyze thermal losses and mechanical resistance in specific components.
Scientifically select construction materials: Choose steels using performance charts, analyze chemical compositions, and define repair methods (welding/inserts).
Use simulation as a mold engineering tool: Set up and analyze simulations to validate a new mold, diagnose problems in an existing one, or guide a re-engineering project.
In essence, you will learn to transform from a technician who follows blueprints into a mold engineer who creates, validates, and optimizes them.

Course Content

1. Principles of Plastic Materials
Go beyond the name on the resin bag. Discover how a plastic's internal structure (amorphous vs. crystalline) dictates its flow, shrinkage, and final part strength. Learn to predict how your material choice will behave inside the mold before you even design it.

1.1 Material Classifications
1.2 Effect of Morphology on Mold Filling Qualities
1.3 Macroscopic Performance Properties of the Part and Variation with Respect to Mold Performance Elements

2: Principles of Plastic Injection Molds
Master the anatomy of the most important tool in manufacturing. We'll decode the blueprint, naming every component from the mold base to the hot runner nozzle. This is the essential language you need to communicate, design, and troubleshoot.

3: Rheology of Plastic Materials
Why does plastic flow? We unlock the science of flow behavior. Learn to calculate pressure drops through runners, predict filling patterns, and scientifically select substitute materials that will work in your existing mold.

4: Basic Calculations of the Injection Molding Process
Replace guesswork with engineering. Perform the three critical calculations for any mold: the clamping force needed to keep it shut, the energy required to cool it, and the design of the cooling channels to make it efficient.

5: Filling Systems
Design the highway that delivers plastic to the cavity. From spruce and cold runners to advanced hot runner systems, learn to size, balance, and analyze every element. We'll cover power needs, thermal expansion, and how to prevent defects at the gate.

6: Construction Materials
Choose the right steel for the job. Move past generic recommendations. Learn to read performance charts, analyze steel chemistry, and select materials for wear, polish, or cooling. Plus, master the protocols for repairing molds by welding and inserts.

7: Simulation Systems
See the future of your mold before it's built. Learn to use CAE simulation as a powerful engineering tool—not a black box. We'll cover how to set up studies for new molds, troubleshoot existing ones, and critically interpret results to prevent costly mistakes.
