Rubber Form
Production of rubber forms without shrinkage
Wax Production and working
Shrinkage by wax shooting- helpful hints.
Filing and tool introduction
Sawing with tool introduction
Drilling with tool introduction
Wax build up with newest techniques
Modeling from wax blocks
Casting with precious stones. Setting in prongs, pavé setting
and invisible. Fast setting up to 100 stones per hour.
For these themes students are required to bring
practice material (wax models etc.) also problem cases, all students
are given their own workbench. During the seminar enough time
is given to practice what is learnt.
LUNCH BREAK
Preparation for Casting
Shrink holes by casting
(Build up, Sprue´s, feeder line, shrink hole paste)
Tree build up (for the different casting methods, spin,
vacuum and pressure)
Investing The wax pieces produced in the morning will be
treed up and invested in the afternoon. Particularly difficult
pieces can be brought along and built up so that all aspects of
casting can be seen.
Finish around 18,00
Casting Flask temperature
Diverse temp differences and there effects.
Casting temperature
Casting Alloys and their effects of crystallization.
New scientific results are discussed
Gas porosity in casting
Examination of gas effects in fluid alloys
Analysis of alloy on the surface.
The prepared trees will be invested, cast and then the results
discussed. Workshop Problems encountered can be discussed during
this time.
