Course: Injection molding defects – Warpage
135.60 $ incl. tax
One of the most critical defects in injection molding is warpage.
Often, extensive modifications on molds are required due to the deviation of part dimensions compared to the nominal geometry.
As in any other defect, there are physical causes behind a given warpage.
This course explains the causes and elaborates strategies to avoid, or at least minimize, warpage on plastic parts.
You will learn
- Root causes of warpage
- Strategies to avoid warpage
- When to apply which strategy
This enables you to
- Identify threats early in the design phase
- Identify best solution strategy
- Solve problems on the shop floor
About the course: Injection molding defects - Warpage
Very often, plastic parts are connected to other components to form an assembly.
Dimensions specified in the design must be observed.
If not, then it may no longer be possible to connect the components.
Unsightly gaps form between the components.
Stresses are applied when molded parts are forced into a certain position, e.g. by screwing.
Dimensional deviations (Warpage) are one of the main problems in the production of plastic parts.
Identifying the causes and what remedies to apply when warpage occurs will be explained in detail during this course.

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.
