The Light RTM process has become significantly popular within our industry as a complimentary process to RTM. This hands-on course will focus on the precision and accuracy needed to produce Light RTM mould from preparation of the master pattern, through to the commissioning of the mould.

The presentation will be of our latest Light RTM technology during the theoretical sessions, and hands-on tool-making techniques and demonstration mould injections in our workshop.

The sessions will cover the following aspects of Light RTM tool build:

• Pattern construction.
• Injection and vacuum port location.
• First mould half construction including heating/temperature control options. Also mould material choice to provide high temperature resistance, accuracy and rapid construction for additional mould laminate structure utilising low profile tooling system.
• Calibrating the product thickness - working successfully with calibration wax and demonstration of solvent based PVA systems for "clean" release.
• Flange calibration for both standard Mushroom and inflatable Dynamic seal.
• Vacuum lock techniques and application during second mould half construction to assure accuracy.
• Second mould half construction. Also mould material choice specifically chosen for the thinner and more flexible contra mould characteristics.
• Optimised design for mould set peripheral framing incorporating low cost - highly efficient latch clamp.
• Opening, clean up, polishing and applying semi-permanent release systems to the completed mould.
• Installation of the mould seals, injection and vacuum fittings.
• Review of the do's and don'ts on fibre loading, core, insert loading into the mould cavity. Pre-injection checks for vacuum cavity.

Practical sessions will show different Light RTM moulds being loaded and injected.

Doubling the output potential of your Light RTM tool set by the manufacture of further matching face tools.

Resume of the classic problems those new to the process experience i.e. vacuum leaks, using too much injection pressure, when to switch off vacuum, damaging the light weight moulds when demoulding, and core absorption of resin etc.
