Course: Injection molding defects – Jetting
135.84 $ incl. tax
Various defects may occur during the injection molding process.
They are annoying and generally need to be eliminated.
For this reason, it is important to understand, how a defects occurs and how to eliminate or even better avoid the defect completely.
This course discusses the subject: “Jetting”, which is the strand-like injection of the melt into the cavity. Causes and solutions will be discussed.
You will learn
- What is the cause of jetting
- Where is the best gate position
- Which processing parameters help for eliminating the defect
- Which further remedial measures are possible
This enables you to
- Understand the causes of jetting
- Eliminate the occurring jetting effect
- Avoiding the jetting already in advance
About course: Injection molding defects - Jetting
Jetting is a strand-like flow of the melt into the cavity. This often results in serpentine patterns on the surface of the molded part. Most of the time this is perceived as a defect, so that jetting is mostly undesired in industry.
It is important to understand the causes leading to this defect. This is the only way to take measures for avoiding the defect.
Countermeasures are available in designing phase and also later during the injection molding process.
In this course, the origins of jetting are discussed. Based on this, all conceivable remedial measures will be clearly described.
For this purpose examples from everyday life are used for illustration.
With this knowledge, the occurrence of the defect is ideally avoided already in the design phase or a quick solution is found in production.

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.
