proves that the employee has understood the training material and is able to apply the knowledge in practical plastic molding.
In these courses, employees progressively expand their understanding of injection molding, learning to diagnose issues and effectively solve problems.
Employees who pass the rigorous Injection Molding 4.0 Driver Licence® exam in Lithuania will have equivalent plastic molding knowledge as their German colleagues.
In traditional training programs, certification is often awarded simply for completing the course. However, the Injection Molding 4.0 Driver Licence® is earned only after successfully passing a comprehensive final exam. Those who pass this rigorous assessment prove their strong theoretical understanding and practical expertise in thermoplastic molding.
Each participant will have to pass several exams consisting of a database of over 400 questions covering all areas of plastic molding, such as plastic materials, tools, and machines.
A significant part of the final exam consists of practical tasks performed in a real factory environment. Participants must analyze and present their results in a written report and answer additional questions during an oral assessment. Successfully passing this part of the exam demonstrates that participants have thoroughly understood the training material and can apply their knowledge effectively when working with plastic injection molding equipment.
and the molding materials used for them: thermoplastic resin and elastomer
and what makes injection molding machines special?
and how to deal with run-off, cooling and tempering
Course 1: Programming of plastic injection molding machines
In this course, participants will gain in-depth knowledge of thermoplastic resins and elastomers, as well as the necessary preparation techniques, such as drying and painting. The main processes covered include charging, plasticizing, and homogenization. Additionally, participants will explore key stages of injection molding—such as the injection process, pressure maintenance, cooling, and ejection.
The course introduces the PVT diagram for amorphous and crystalline polymers, helping participants understand material behavior and how to apply it practically. They will also learn to identify and solve common defects like deformations, gloss inconsistencies, moisture marks, and burn marks. Advanced training is provided on the ejection process, mold technology, mechanical functions, and heat transfer, ensuring a well-rounded understanding of injection molding operations.
Course 2: High-tech materials and process optimization
The second course focuses on high-tech materials and specialized machinery used in modern injection molding processes. Participants will gain insights into energy-saving techniques and learn how to optimize operations to reduce costs while improving product quality. The course also covers advanced molding techniques and innovations in the injection process, emphasizing more efficient and sustainable production practices.
Course 3: Injection Molding Practice and Process Observation
This course builds on the knowledge from the first two courses, combining theoretical concepts with practical experience in injection molding. Participants will learn how to monitor and control the process, perform systematic sampling, and implement accurate record-keeping procedures. Topics covered include cooling and tempering technologies, pulse cooling, and advanced process settings, such as configuring mold sensors (pressure and temperature). The course culminates in preparation for a practical exam, simulating real-world applications in industries such as automotive, household appliances, and packaging.
Course 4: Injection Molding Technologies and Optimization
This course is designed to provide a deeper understanding of injection molding technologies, methods for storing and managing important data. It covers Moldflow, a flow simulation software that can be used to optimize the cooling process. Participants will learn special molding and ejection techniques, such as label injection or rapid prototyping, and seal point determination. It will also cover cycle time optimization and successful loading.
Course 5: Course Review and Testing
In the final course, participants will discuss the results of practical tests, review the main points of all courses, and participate in a lesson with a test questionnaire. The course concludes with an oral and written exam to obtain an injection molding license.
