Lost-Wax Micro-Casting Course
Online 300-hour course in lost-wax micro-casting. 6 modules covering ISO 8062-3 (dimensional tolerances of castings), UNE-EN 1982 (copper and copper alloys, castings) and ProCAST. Assigned tutor and open enrolment.
Take the controls.
Run a real engineering trade-off from this programme. Move the sliders, watch the model react in real time and beat the challenge.
What you will be able to do
Explain the lost-wax process and its suitability for small parts.
Make wax or printed patterns that reproduce the original part.
Prepare the investment and carry out dewaxing in a controlled way.
Melt and cast alloys suited to the type of part.
Finish and check the parts obtained against tolerances.
Organise a small, safe and cost-effective micro-casting workshop.
Reproduce a small part from a classic vehicle by lost-wax casting.

How you'll learn
Fully 100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: students progress at their own pace within the intake, which makes it easy to combine with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is ProCAST, Fusion 360, PrusaSlicer, Advanced Excel, in free, academic or evaluation versions. Tests are studied through real procedures for making wax and printed patterns, investment, dewaxing and casting, dimensional control and liquid penetrant inspection. Assessment is continuous per module plus the final integrating project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
