Plastic innovatively shaped
In addition to other major plastics processing methods, injection molding is one of the most frequently used primary molding processes. The range of molded parts that are produced fully automatically and cost-effectively by injection molding extends from simple mass products to complex, technical components and assemblies. Within this spectrum, we can also support you with targeted preliminary tests based on a wide variety of test and specimen samples.
- Simulation for molded part and tool design
- Sampling of tools
- Demolding force measurement for mold coatings or for the evaluation of additives
Analysis and optimization
- Defect analysis on injection molded parts and development of elimination strategies
- Technology optimization with regard to quality, cycle time and energy consumption
- Investigations into the processing behavior of thermoplastic materials
- Calibration of injection molding machines
- Injection molding of test and specimen bodies, plates, etc.(KUZ molded parts catalog)
- Injection molding of micro parts and fine structures
- Small batch production
Online defect catalog
Spritzgiessfehler.de - is the online defect catalog of the Kunststoff-Zentrum in Leipzig (KUZ). This tool gives you quick access to clearly structured information on the subject of injection molding defects. Defects can be displayed directly, but can also be sorted from different perspectives, such as that of the molding developer, the material manufacturer or the mold designer. With free access, you benefit from our experience and knowledge of defect prevention and scrap minimization. You can look forward to the extension of the defect images at regular intervals.
Already listed are for example:
What to do if the molded part weight fluctuates?
Possible cause: e.g. shrinkage cavities due to insufficient shrinkage compensation.
- Increase of holding pressure
- Extending the holding pressure time
- Avoidance of large wall thickness jumps as well as mass accumulation
- Checking and, if necessary, enlarging the nozzle bore, the gate and gate cross-section
- Checking and, if necessary, changing the gating position
What to do if weld lines appear on injection molded parts?
Possible cause: e.g. melt temperature too low.
- Increase the melt temperature
- Increase of mold temperature
- Adjustment of injection speed, etc.
What to do if warpage occurs on the molded part?
Possible cause: e .g. holding pressure effectiveness too low.
- Improvement of the holding pressure phase
- Adaptation of the cooling phase
- Optimization of the injection speed, etc.
The Injection Molding Advisor is a handy, compact tool for processors in A5 format with two rotating selection wheels, similar to a parking meter. Easy to use, the tool can be used to determine material-specific processing parameters or provide assistance for injection molding troubleshooting. On the front side, 24 different material data of common as well as special plastics such as COC or PEEK are listed and on the back side, 24 injection molding errors are additionally listed, which offer the processor assistance for the injection molding error correction.

Plastics selection in product development
Plastics are highly interesting materials with further increased potential for product development. A multitude of requirements to which the product is subjected in the application must be reconciled with the most efficient processability possible and a limited cost budget for the material. This seminar explains some basic tools for solving this complex problem. The content of the seminar is to underline the practical approach from the material selection to the real use of the product. Using a housing made of semi-crystalline material with/without filler and a lens made of amorphous material, the seminar content will be taught in a practical way.

Injection molding compact in theory and practice
If you are familiar with the basics of the injection molding process, this extension course will give you additional knowledge about injection molding of thermoplastics. We will explain the phases of the injection molding process to you in detail, look at the input variables and their influence on the molded part quality. In an extended practical part, the theoretical contents will be illustrated for you in a practice-relevant way on an injection molding machine. You will find further information on the agenda, how to get there, parking facilities and an insight into the script in our download box at the top right.
Multi-component injection molding
Various special injection molding processes can be used to produce more complex components that not only offer cost advantages but also higher-quality features compared with individual components, e.g. through increased functional integration. For example, multi-component injection molding can produce composites from several components of the same or different types. A key quality feature in the injection molding of two or more components is the adhesion between the different materials. For this reason, material selection and molding design are particularly important. In this seminar, we will teach you the basics of multicomponent injection molding technology and demonstrate technical approaches to solutions.

Dimensional accuracy of molded parts
The special structure of plastics, which results from their molecular structure and essentially determines their properties, gives rise to some special features for the dimensioning and tolerancing of plastic parts compared to other construction materials. If these are not taken into account in molded part and tool design, this inevitably leads to disputes between plastics processors, toolmakers and OEMs. Get fit and use the plastics technology know-how of the new standard for effective project processing!
