Module content
Lectures (10h):

Methods of making foundry moulds and cores (the division of moulding and core sands into generations).
Properties of matrix and binder of classic moulding sands (1st generation moulding sand). Technologies for the production of classic green sands. Processes for refreshing moulding sands.
Moulding sands bonded with organic and inorganic binders (moulding and core furnaces of the second generation). Technology of loose self-hardening moulding sands. Properties, advantages and disadvantages of the moulding sands, application. Cold-box technology. Properties, advantages and disadvantages of the moulding sands, application. Hot-box technology. Properties, advantages and disadvantages of the moulding sands, application.
Moulding sands bound with physical factors (3rd generation). Types and characteristics of processes.
Moulding sands bound with biotechnological factors (4th generation).
Alternative methods of moulding sands curing.
Methods for regeneration of moulding and core sands.
Methods for determining the harmfulness of moulding sands to the environment.

Laboratory classes (20h):
  1. Influence of curing time on bending strength (Rgu) and stretching strength (Rmu) of loose self-hardening moulding sands with synthetic resin (SMS).

    Exercise allows to determine the strength properties of loose self-hardening moulding sands with commonly used in foundry practise organic binders. The student gets acquainted with selected properties of 2nd generation moulding sands, their disadvantages and advantages.

  2. Influence of curing time on bending strength (Rgu) and stretching strength (Rmu) of loose self-hardening moulding sands with hydrated sodium silicate.

    Exercise allows to determine the strength properties of loose self-hardening moulding sands with environmentally friendly inorganic binders. The student gets acquainted with selected properties of 2nd generation moulding sands, their disadvantages and advantages.

  3. Influence of curing time on bending strength of microwaved hardened moulding sands with hydrated sodium silicate

    Exercise allows to determine the strength properties of microwaved hardened moulding sands with inorganic binders.

  4. Influence of curing time and temperature on bending strength of thermally hardened moulding sands with hydrated sodium silicate

    Exercise allows to determine the strength properties of thermally hardened moulding sands with inorganic binders.

  5. Influence of cold-box generation type on strength properties of moulding sands.

    Exercise allows to determine the strength properties of moulding sands prepared in different cold-box generation types.

  6. Final passing
Additional information
Teaching methods and techniques:
  • Lectures: The content presented at the lecture is provided in the form of a multimedia presentation in combination with a classical lecture panel enriched with demonstrations relating to the issues presented.
  • Laboratory classes: During the laboratory classes, students independently solve the practical problem, choosing the right tools. The leader stimulates the group to reflect on the problem, so that the obtained results have a high substantive value.

Participation rules in classes:
  • Lectures:
    – Attendance is mandatory: Yes
    – Participation rules in classes: - Obligatory presence: Yes - Rules for participation in classes: Students participate in classes learning further content of teaching according to the syllabus of the subject. Students should constantly ask questions and explain doubts. Audiovisual recording of the lecture requires the teacher's consent.
  • Laboratory classes:
    – Attendance is mandatory: Yes
    – Participation rules in classes: - Obligatory presence: Yes - Rules for participation in classes: Students perform laboratory exercises in accordance with materials provided by the teacher. The student is obliged to prepare for the subject of the exercise, which can be verified in an oral or written test. Completion of classes takes place on the basis of presenting a solution to the problem. Completion of the module is possible after completing all laboratory classes.
Method of calculating the final grade:

Presence at lectures – 20%. Laboratory classes passing – 30%, exam – 50%. Laboratory classes passing and exam may take place in an oral form – the decision is taken by the instructor on the basis of the number of persons joining the next exam (passing) period.
