From vessel components to custom marine enclosures, Hill Plastics delivers precision thermoforming and fabrication built to withstand the demands of saltwater environments and constant UV exposure. With over 45 years of manufacturing expertise, we produce marine-grade plastic parts—from prototype to high-volume runs—using UV-resistant materials and tight tolerances that keep your project on time and on budget.
Comprehensive thermoforming and fabrication solutions engineered specifically for the demanding requirements of marine applications.
Custom vacuum and heavy-gauge thermoforming using UV-resistant ASA/ABS and HDPE materials ideal for marine environments. Eight thermoforming machines handle everything from small components to large 5'x9' marine panels.
Precision CNC trimming of marine thermoformed parts to exact drawing specifications. Two 5'x10' CNC trimming centers deliver clean edges, accurate contour cuts, and repeatable quality for marine enclosures and OEM components.
Custom plastic fabrication services including heat bending, bonding, precision drilling, and fastener installation for marine-grade parts. Finished components meet exact specifications for enclosures, guards, and structural marine elements.
Low-cost wood and polyurethane prototype tooling through full aluminum production molds for marine applications. Fast-turnaround master patterns allow fit-and-function review before committing to production tooling.
Rapid marine component prototypes using low-cost wood or polyurethane tooling. A master pattern can typically be produced within weeks, enabling design review and functional testing before full production commitment.
Scalable marine parts production from short runs to thousands of units. The 4'x7' rotary thermoforming machine runs 2.5x faster than standard equipment, delivering competitive pricing on large marine OEM orders.
Marine environments demand materials that resist UV degradation, saltwater corrosion, and mechanical stress—and Hill Plastics delivers exactly that. Using UV-resistant ASA/ABS, HDPE, and other performance-grade materials, we produce custom thermoformed marine components that hold up in harsh on-water conditions. From custom enclosures and instrument panels to structural OEM parts, our Lewisville, TX facility operates over 20,000 square feet of manufacturing space with eight thermoforming machines and full CNC fabrication capabilities to support your marine project from first prototype through high-volume fulfillment.
Discover how marine and OEM manufacturers rely on Hill Plastics for precision, quality, and on-time delivery.
"Great value, family business, personal attention. Over the years, Cody, Brad, and Aubrey have become valued associates in my small enterprise. Willing to tackle design challenges. Get-her-done communications. Outreach to additional sources of expertise. These folks understand the inventive process. Cody for example is a Kickstarter supporter and is familiar..."
"Hill Plastics did a great job creating a substitute back window for my RV. I have a portable mini-split air conditioner that I use in extremely hot weather to supplement my RV’s own cooling power. The mini-split has an inside unit that blows the cold air and an outside condenser..."
