Familiarize the students with tasks related to mould design. Product technical check. Systemic approach to mould design. Modern computer tools for mould design. Partial product cost calculation.

Student responsibilities:

Grading and evaluation of student work over the course of instruction and at a final exam:

Seminar paper and its presentation

Methods of monitoring quality that ensure acquisition of exit competences:

Recording of attending lectures and active participation of students in discussions during lectures. Continuous monitoring of consultations during seminar preparation.

Upon successful completion of the course, students will be able to (learning outcomes):

After sucessful lecturing student will be able to: -evaluate a mould for injection moulding of polymers as a system -estimate design solutions for each partial mould function -rheological, mechanical and thermal mould evaluatuion - design a simple mould for injection moulding -select aproriate materials for mould manufacturing -generate appropriate technical documentation of mould
