Introductory Seminar: Learn Precision Extrusion Molding for Tubes, Films, and Sheets in One Day

IR Engineers Education Institute will hold an online course, "Introduction to Precision Extrusion Technology," for engineers new to extrusion molding.

Extrusion molding for products like tubes, films, and sheets is essential in many manufacturing sites. However, understanding the process often relies heavily on empirical rules, and terminology and judgment criteria tend to vary among individuals. Particularly for beginners and young engineers, limited opportunities for systematically learning the basics can make it difficult to share information and prevent recurrence of problems. This course aims to organize the "technical common sense" of extrusion molding and provide knowledge that can be used as a common language in the field.

Seminar Overview

• Seminar Name: Introduction to Precision Extrusion Technology

• Format: Online course via Zoom

• Date and Time: May 29, 2026 (Friday), 10:00 AM - 4:00 PM

• Fee: 49,500 JPY (tax included) / per person (group discount available)

• Instructor: Takashi Kaneko (Head of Kaneko Engineering Office)

Course Details

This course is designed for "engineers new to extrusion molding" and will organize the basics of extrusion molding and the necessary practical perspectives in one day. Even those who have not majored in polymers at university will find it easy to understand, starting from material characteristics and the relationship between viscosity and molding processes. It covers the names and functions of each part of a single-screw extruder, the concept of plasticization, and the basic process of extrusion molding.

In the latter half, the course explains the basics (common sense) of die design and screws, along with examples of handling different resins. Furthermore, it organizes the types and terminology of common extrusion molding defects encountered in the field, and introduces specific countermeasures (case examples). Analysis using CAE will also be explained in an understandable way, using experimental data, simulation results, and computational models. As special extrusion topics, it will cover small-diameter extruders (for medical use) and case examples of profile extrusion and multi-layer tube molding.
