Fiberglass, gelcoat and topcoat

Lesta robots offer dedicated automation for fiberglass spraying, gelcoat and resin application, requiring equipment able to handle abrasive and viscous materials continuously, while maintaining consistent precision and application speed. This is an increasingly important requirement in shipbuilding and composite manufacturing. In addition to industrial painting, Lesta robots also adapt to these applications thanks to a dedicated software package, in a way comparable to how fiberglass composites are processed across many industrial sectors.

The fiberglass spraying package of Lesta LECROB Robot Manager

The Lesta LECROB Robot Manager software includes a dedicated package for fiberglass spraying, designed to automatically manage the most delicate phases of the process:

• Automatic post-cycle washing: the robot autonomously washes the nozzle at the end of each cycle, reducing downtime and manual maintenance.
• Fiberglass dosing via chopper management: the system automatically regulates fiberglass delivery, ensuring uniform distribution on the piece.
• Gelcoat and resin valve management: valve opening and closing synchronized with the robot’s path, avoiding material waste and ensuring consistent thickness.

This software package makes Lesta robots a complete solution for those working with composite materials, combining the flexibility of self-learning programming with automatic management of the most delicate phases of the spraying cycle.

Application sectors for fiberglass spraying

Lesta’s solutions for fiberglass spraying, gelcoat and resin are used in several sectors: marine (hulls and boat and ship components), prefabricated pools and tanks, campers and caravans, as well as structures such as horse shelters. Each sector presents different geometries — from hulls with curved and complex surfaces to tanks with more regular shapes — and Lesta robots, thanks to self-learning programming, quickly adapt to each configuration without the need for complex reprogramming.

Why automate fiberglass and gelcoat spraying

Manually applying fiberglass, gelcoat and resins involves prolonged operator exposure to dust and vapors, as well as high variability in coating thickness and quality from piece to piece. By automating the process, the application path is recorded only once thanks to self-learning technology and automatically reproduced on every subsequent piece, reducing direct staff exposure and ensuring consistent quality. Like all Lesta solutions, these systems are also designed and manufactured entirely in Italy.
