Aim
The aim of the course is to acquaint students with polymer processing technologies (materials, machines, technology, parameters), pre-processing steps, extrusion (eg film, profile, plate, tube, wire coating), hot forming, hollow plastic parts production methods ( extrusion blow molding, injection molding, rotational molding, two-layer thermoforming), polymer foams and elastomers processing technology.
Learning outcomes
Competences that can be acquired by completing the course
Knowledge
Knows basic polymer processing technologies. Define the concepts of viscosity, shear deformation and MFI. It provides an overview of the entire polymer processing process (from the raw material to the finished product). He is aware of the preparatory steps for polymer processing. Understands the extrusion process and the extruder tool. Understands the operation of basic hollow body manufacturing technologies. He is knowledgeable about thermoforming technologies for thermoplastics. Knows the basic foaming procedures, their characteristics. Knows the basic rubber processing technologies. He is familiar with basic polymer bonding technologies.
Ability
It is able to differentiate between polymer processing technologies. Selects a raw material of the right quality for the given processing technology. It designs the manufacturing process of the entire polymer product (from raw material to finished product). Selects the appropriate raw material preparation processes for the specific product manufacturing technology. It analyzes the extrusion process as well as the extruder forming tool. It separates the production technologies suitable for the production of the main hollow body. It distinguishes between the main heat-forming processes. Select the appropriate foaming process, taking into account the requirements of the particular product. It differentiates between basic rubber processing technologies. He chooses the appropriate knitting technique taking into account the specifics of a given product.
Attitude
It constantly monitors its findings and conclusions. He is constantly expanding his knowledge in the field of polymer processing. Open to the use of information technology for problems with polymer processing. It strives for accurate problem solving and engineering accuracy. It supports the spread of energy efficient and sustainable technologies. It strives to apply the latest trends and technologies in the field of polymer processing.
Independence and responsibility
With his knowledge, he makes a responsible, well-founded decision based on his analyzes. Accepts well-founded professional and other critical remarks. As a member of a team, he works together to solve technical problems. Is committed to the principles and methods of systematic thinking and problem solving. Feels a responsibility for the sustainable use of the environment and for present and future generations.
Teaching methodology
The course integrates optional frontal lectures and mandatory laboratory sessions. Presentations include hands-on presentations as well as PowerPoint presentations. Polymer processing technologies are also demonstrated using short videos available on the Internet. Various polymer processing techniques are demonstrated during laboratory practice. The acquired knowledge is further deepened by practical home preparation and online study materials.

Validity of the course description
| Start of validity: | 2022. July 16. |
| End of validity: | 2027. July 15. |
General rules
The signature requirement is (1) at least 4 successful laboratory measurements and (2) successful submission of homework. Student participation in the measurement should reflect previously defined knowledge, skills, attitudes, and autonomy competencies. The requirements for the final grade are successful mid-term examinations as well as submitted homework that meets the requirements at least to a sufficient degree.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | summative assessment | |
| Number: | 1 | |
| Purpose, description: | The end-of-semester examination includes the full curriculum. Students must provide the definition, draw a schematic diagram of the different processing methods, and draw the necessary curves (e.g., vulcanization curve, thermomechanical curves). Students should select an appropriate method for the production of a given product and describe it briefly. | |
| Mid-term assessment No. 2 | ||
| Type: | diagnostic assessment | |
| Number: | 6 | |
| Purpose, description: | The aim of the assessment is to identify the prior competences of students to carry out laboratory exercises. The assessment papers are therefore written by the students at the beginning of the laboratory practice. The time available is 10-15 minutes. Only students who have brought the required equipment: their own, blank protocol, calculator, identity card. To complete the laboratory practice, one must successfully pass the control paper written at the beginning of the laboratory exercises (more than 40%) and actively participate in the laboratory exercises. If the student does not show sufficient activity in the laboratory exercises, one may be dismissed. In this case, the laboratory practice will be considered as unsuccessful, regardless of the result of the control assessment, and must be retaken, where the control test will have to be repeated. | |
Detailed description of assessments performed during the examination period
The subject does not include assessment during the examination period.
The weight of mid-term assessments in signing or in final grading
| ID | Proportion |
|---|---|
| Mid-term assessment No. 1 | 80 % |
| Mid-term assessment No. 2 | 20 % |
The weight of partial exams in grade
There is no exam belongs to the subject.
Determination of the grade
| Grade | ECTS | The grade expressed in percents |
|---|---|---|
| very good (5) | Excellent [A] | above 91 % |
| very good (5) | Very Good [B] | 86 % - 91 % |
| good (4) | Good [C] | 71 % - 86 % |
| satisfactory (3) | Satisfactory [D] | 56 % - 71 % |
| sufficient (2) | Pass [E] | 41 % - 56 % |
| insufficient (1) | Fail [F] | below 41 % |
The lower limit specified for each grade already belongs to that grade.
Attendance and participation requirements
The lack of the value means that there is no attendance requirement.
At least 85% of laboratory practices (rounded down) must be actively attended.
Special rules for improving, retaken and replacement
The special rules for improving, retaken and replacement shall be interpreted and applied in conjunction with the general rules of the CoS (TVSZ).
| Need mid-term assessment to invidually complete? | ||
| yes | ||
| The way of retaking or improving a summary assessment for the first time: | ||
| each summative assessment can be retaken or improved | ||
| Is the retaking-improving of a summary assessment allowed, and if so, than which form: | ||
| retake or grade-improving exam not possible | ||
| Taking into account the previous result in case of improvement, retaken-improvement: | ||
| new result overrides previous result | ||
| Completion of unfinished laboratory exercises: | ||
| missed laboratory practices must be performed in the repeat period | ||
| Repetition of laboratory exercises that performed incorrectly (eg.: mistake in documentation) | ||
| incorrectly performed laboratory practice (e.g. Incomplete/incorrect report) can be corrected upon improved re-submission | ||
