This self-paced online course gives you the technical knowledge required to understand how propeller patterns are designed and prepared for metal casting. Focusing on the theory behind the process, the course explores the unique design challenges of marine and industrial propellers, including complex geometry, blade profiles, and balancing considerations.
You’ll learn about patternmaking principles specific to propellers, such as split pattern construction, shrinkage and machining allowances, and the use of templates or profile gauges.
This course is ideal if you’re an apprentice, technician, or student looking to specialise in patternmaking for casting propellers used in marine, industrial, or power transmission applications.
