Course: Surface defects
135.60 $ incl. tax
After an injection molding part is ejected, some unwanted dull spots or, in contrary to that, some shiny areas can be seen on the surface.
Since the mold itself is flawless the surface defects must have another cause.
This course will describe the causes that might generate different surface irregularities on a plastic part.
You will learn
- How to identify different surface defects
- What are the causes of the defects
- Which parameters have the main influence
This enables you to
- Find the best solution to solve defect problems
- Ensure high quality parts
- Choose the right settings to avoid surface defects
About the course: Surface defects
Action is required if a part produced with a good mold shows different gloss on the surface.
The type of surface defect must be identified in order to find a solution.
Adjustments of the parameters on the injection molding machines are needed.
In this course, the basics of surface defects are discussed. Along with that solutions are provided that will lead to good parts.
This course is for
Everyone who is curious about the topic.
This includes especially people working as:
- Part designer
- Mold designer
- Mold maker
- CAE-team
- Setter
- Injection molder
- Quality manager
- Department leader

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.
