Composite Tooling Fabrication (Stage I)

Course code: TECH-170 (Stage I)
Course duration: 5 Days


This is our In-depth tooling course (Stage I) which is designed and meant for Personnel of technical departments who want learn more about tool design and fabrication techniques to achieve tool stability and long long life cycles
All theory will be applied in the workshop to fabricate an excellent tooling mould.

Advised pre-requisites

Our EFC Courses, TECH-001-(Stage I) is a prerequisite, Previous experience with composite materials and layup is required for this course, or an equivalent level. Please, if in doubt contact us to assess your equivalent level of training.


Personnel of technical departments, tool designer, tooling engineer, tool fabricator, composite repair technician and others who want to learn about tool design and achieve in-depth skills in Composite Tooling fabrication and will be able to design and build moulds using Low Temperature Moulding (LTM) composite pre-preg materials.

Number of participants

Minimum required 2 and Maximum 12 per course*.

* Courses will be confirmed as running by EFC as soon as sufficient applications are received!


At the end of the course the participants:

  • Has a better knowledge of composite tool design
  • Knows the pre-preg part tooling routes
  • Knows and has the skills to surface preparation of a master model
  • Can read and understand Tooling Ply-Lay-Up drawings and tool design tolerances
  • Is familiar with tool index and trim fixtures
  • Can apply Tool back-yup structure stiffeners, fences, return flanges, egg crate or omega stiffeners design
  • Knows how to use and work with Wax sheet offsets
  • Can apply vacuum bags for tooling
  • Will have advanced knowledge and skills to apply of Low Temperature Moulding (LTM) materials
  • Has the knowledge and skills to fabricate quick composite reinforced repair tooling.
