Dedika for businesses

What you will learn:

You will learn how fibreglass fibres, resin systems, and core materials work together and how to select the right combination for any application. The course walks you through open-mould hand layup, spray-up, vacuum infusion, and autoclave prepreg processing so you can work confidently across multiple fabrication methods. You will build and finish production moulds, control laminate quality, and use non-destructive testing to detect internal defects. Repair techniques cover both cosmetic gelcoat restoration and full structural repairs with engineered ply schedules.

    Addresses mould polishing, repair, and ongoing maintenance to extend service life. Connects mould condition to consistent part surface quality.

  • Lesson 2 • Mold Surface Preparation and Gelcoat

    Details mould release agent application and gelcoat layup for a durable mould surface. Proper preparation prevents adhesion and surface defects in production parts.

  • Lesson 3 • Plug and Pattern Construction

    Explains how to build master plugs from foam, wood, or existing parts. Connects plug quality directly to mould surface accuracy.

    Covers draft angles, parting lines, and flange design for successful part release. Establishes design rules that prevent costly tooling failures.

  • Lesson 5 • Laminating the Mold Shell

    Covers skin coat, backup laminate, and stiffener integration for a rigid mould structure. Ensures the mould withstands repeated production cycles without distortion.

Chapter 4See details

Hand Layup and Spray-Up Processes

  • Lesson 1 • Spray-Up Process and Equipment

    Covers chopper gun operation, roving selection, and spray pattern control for spray-up lamination. Links operator technique to laminate thickness uniformity and mechanical properties.

  • Lesson 2 • Hand Layup Lamination Technique

    Explains wet-out, consolidation, and ply sequencing for hand layup laminates. Correct technique eliminates voids and ensures fibre-to-resin ratio targets are met.

  • Lesson 3 • Gelcoat Application Techniques

    Teaches spray and brush gelcoat application, thickness control, and cure verification. Gelcoat quality determines the cosmetic and protective performance of the finished part.

  • Lesson 4 • Workspace and Process Setup

    Covers environmental controls, material staging, and equipment preparation before lamination. Proper setup reduces defects and improves laminate consistency.

  • Lesson 5 • Cure Monitoring and Part Demolding

    Addresses gel time, cure exotherm, and safe demoulding criteria for open-mould parts. Prevents premature demoulding that causes warpage or surface damage.

Chapter 5See details

Vacuum Infusion and Closed-Mold Processes

  • Lesson 1 • Infusion Consumables and Bagging Materials

    Covers peel ply, flow media, spiral tubing, and vacuum bag film selection and placement. Correct consumable selection directly controls resin distribution and laminate quality.

  • Lesson 2 • Resin Infusion Execution

    Covers resin mixing, pot life management, feed line setup, and flow front monitoring. Successful execution requires coordinated timing and real-time process adjustment.

  • Lesson 3 • Dry Fabric Layup for Infusion
