Course: Injection molding defects – Dimensions
135.60 $ incl. tax
The dimensional accuracy of plastic parts is important for any subsequent application.
Due to the injection molding process and the property of plastics to shrink to a greater or lesser extent, it is a challenge to ensure dimensional accuracy.
You will learn
- More about the causes of dimensional deviations
- Why there are shrinkage differences
- And find out what role crystallization plays
This enables you to
- Initiate favorable measures at an early stage
- Design tools correctly
- Set process parameters in the best possible way
About the course: Injection molding defects - Dimensions
It is known that plastic parts shrink after production.
Based on the design of the molded parts and the tool and depending on the position of the connection, the shrinkage and thus also the change in dimensional accuracy can vary.
The material selected for the production of a molded part naturally plays a decisive role.
Therefore, in addition to the causes of dimensional deviations, this course also deals directly with solutions for influencing shrinkage. The special features of semi-crystalline plastics are discussed in a separate chapter.
After the course, you will have an understanding of the causes of dimensional deviations and practical solutions.
This course is for

- Part designer
- Mold designer
- Mold maker
- Setter
- Injection molder
- Quality manager

Course Specialist
CEO at STAK
For many years, Prof. Dipl.-Ing. Peter Wippenbeck has been connected to injection molding technology. He started with mechanical engineering and application technology. Even then, the aim was to achieve a perfect product with the best possible economic efficiency. Quite a few customers confronted him with problem cases and asked for solutions and optimized settings in production.
He took on teaching duties at Aalen University, in Germany, in the field of plastic technology in the 70’s to examine the experiences from industry and to pass on his knowledge to future generations of engineers. Soon, he got a managing position there. His work, with international cooperation, led to the establishment of the master’s degree program in Polymer Technology.
Initiated by the professional association of GKV (called TecPart), industrial training in the field of injection molding was intensified additionally to the engineering degree: Several thousand participants at seminars have already been trained by him and qualified in Aalen including a considerable number of foreign employees and trainers, especially from Thailand, India and Indonesia.
In organizational terms, these activities are located at the Steinbeis Innovationszentrum Kunststofftechnik (SIZK, a non-profit company of Steinbeis Innovation gGmbH), while problem-solving is the responsibility of the Steinbeis Transfer Zentrum Aalen Kunststofftechnik (STAK). In both institutes, the author has been engaged in knowledge transfer in the sense of quality improvement and efficiency in injection molding technology.
