Finally, robotic sanding that works with your existing process

The marine manufacturing industry has been pursuing robotic sanding automation for years, but first-pass fiberglass work has remained stubbornly manual. While automation has succeeded in other manufacturing sectors, the specific requirements of freshly molded fiberglass components have defeated most robotic approaches.

The unique requirements of boat builders

Historically, marine manufacturers have relied on manual block sanding to even out warping, dimpling, and rippling that is characteristic of large, freshly molded fiberglass parts. But faced with persistent labor shortages, boat builders need automation that solves their workforce challenges without forcing them into lengthy, expensive operational redesigns. The challenge is that automated orbital sanding isn’t suited for correcting surface irregularities from the fiberglass molding process.

The orbital mismatch in first-pass sanding

Block sanders are the tool of choice for this first stage of fiberglass sanding because they work well. Long, straight tools naturally bring high points down to the level of low points through consistent pressure distribution, producing surface uniformity.

To be clear, orbital sanding isn't inherently problematic—it excels in later stages where surfaces have already been leveled and smoothed. But when applied to the uneven surfaces of freshly molded fiberglass, this approach exacerbates the very surface irregularities that manufacturers aim to correct. The fundamental issue is geometric: orbital sanders just don't span the valleys.

The right sanding solution needs to be built on the most effective technique: block sanding. The key to unlocking automation in fiberglass sanding is a system flexible enough to handle the variable geometries, surface conditions, and workflow requirements that make this work so labor-intensive.

Bringing proven technique to scale

That’s why Viam developed the first robotic solution that automates the block sanding approach boat builders already use for first-pass sanding. Our system is mobile, enabling it to integrate directly into existing workflows. The system moves to your workpieces rather than requiring transport of large components to centralized automation stations. Using AI-powered 3D imaging, it adapts to actual component geometry without requiring CAD models or precise positioning. The approach is designed to fill labor gaps while maintaining quality, all without requiring massive operational redesign.

As labor shortages intensify across marine manufacturing, the companies that successfully automate their most labor-intensive processes without compromising quality will define the industry's competitive landscape. As an example, Viking Yachts, in partnership with Viam, is taking the first steps towards sanding automation at their 1 million square foot facility in New Gretna, NJ. As Professional BoatBuilder reported on the solution: "Viam created a tool that automates as much of the unpleasant task of block sanding as possible for the skilled technician operating it." Finally, there is an opportunity to modernize first-pass fiberglass work that works for the realities of marine manufacturers.
