Hull Construction –Infusion Molding vs. Hand Laid and Vacuum Bagging

In a high-performance environment, all that separates you from the water is your boat hull. Hull construction and performance is critical.

Proprietary Hulls

Our boat hulls were designed and constructed by Liquid Glass Powerboats from scratch in our factory. The hulls are exclusively unique and proprietary to our Company.

Out with the Old

Liquid Glass Powerboats has technologically leapfrogged the antiquated, less-precise technologies of vacuum-bagging and hand laying hulls. These techniques yield lower quality hull reliability, performance, and reduced aesthetics.

Vacuum bagging and hand laying yields a resin to glass ratio of 60% resin to 40% fiberglass (at best), which is far from ideal. Hull strength is achieved from fiberglass, not from resin. Resin only makes a boat heavier, not stronger.

The Future: Infusion Molding

We build boats using infusion molding. The concept works as follows:

Fiberglass reinforcement is placed in a mold set
The mold is closed and clamped
Resin is injected into the mold cavity under pressure

The motive force is pressure therefore, the pressure in the mold cavity is higher than atmospheric pressure. In contrast, vacuum bagging methods use vacuum as the motive force, and the pressure in the mold cavity is lower than atmospheric pressure.

Once infused, the fiber cures with exact durability, quality, and volume specifications, leaving nothing to chance or variability. The result is a remarkable 70% fiberglass to 30% resin ratio. The entire process is environmentally clean and friendly with no toxic emissions.
