Methods of cold stamping and their characterization. Trimming dies, precision dies, bending dies and tensile dies - their design and calculation. Computation of forces and measurements. Typical constructions, units and parts. Manufacturing accuracy of stamp components. Materials for making stamp parts. Manufacturability of stamps design. Hard metal stamps, the specific features of their design.
Extrusion methods of plastics. Classification and characterization of die sets.Construction of different types of die sets (including moulds).
Checking of knowledge: exercises, tests and pass/fail examination.

Course paper task: to design multiposition or combined trimming, bending or tensile die, using the part’s technical drawing. To determine the sequence of stamping operations. To make necessary calculations for stamping: forces, measurements and strengths of stamp parts. To select stamp parts, construction elements, units and material for parts. To make technical drawing of stamp and assembly drawing of matrix. To draw up explanatory letter.

The goal of the course is to provide knowledge of
1. cold working methods, cold stamps of sheet metals and die sets of plastic
2. typical constructions and materials of stamps, basic principles of design and technological computation
3. methods of extrusion of plastics, design of different types of die sets

The aim of the course paper is to get practical experience in designing and calculating of stamps for cold stamping.

After completing the course a student
1. has a general overview of cold stamping methods of sheet metals, and a detailed overview of trimming, bending and tensile dies
2. is able to determine the required forces for stamping, to make technological and construction designs of stamps and dies
3. is familiar with die sets for processing of plastics using extrusion and injection moulding methods

After completing the course paper a student
1. has an overview of construction and working operation of multiposition trimming, bending and tensile dies
2. is able to determine the required forces for stamping, to make technological and construction calculations of stamps, is able to select materials for stamp parts
3. has some practical knowledge of designing stamps and is familiar with the requirements of making technical drawings of stamps. Assessment of completed tasks.

1. 32 hours of lectures according to the syllabus topics.
2. 8 hours of practical session: calculation of forces and measurements of different stamps.
3. Independent work of 40 hours. Solving individual tasks of determining the required forces, measurements and compression centres in the stamping process. Assessment of completed tasks.

4. Classroom tests.

Course project:
1. 8 hours of practical session. Measuring, determining centre of compression of different stamp types. Selection of construction parts.
2. Consultations.
3. 42 hours of independent work. Task: according to the technical drawing of a part, to design a suitable multiposition or combined trimming, bending or tensile die for making this part. Assessment of completed tasks.
