From the high-altitude industrial facilities of Colorado's Front Range to aerospace suppliers along the Rocky Mountain corridor, Hill Plastics delivers precision plastic fabrication services backed by 45+ years of expertise. We offer custom thermoforming, CNC trimming, mold making, and prototyping—engineered to spec, on budget, and on schedule for OEMs and industry leaders nationwide.
Comprehensive custom plastic fabrication solutions—from design and prototyping through high-volume production—serving diverse industries nationwide.
Custom thermoforming and vacuum forming using eight machines ranging from 2'x3' to 5'x9'. We heat and form plastic sheets over precision molds to produce enclosures, trays, OEM parts, and industrial components with tight tolerances.
Expert fabrication of custom POP displays, industrial parts, and secondary trim operations. Services include precision trimming, drilling, assembly, heat bending, bonding, riveting, and threaded inserts—all CNC-trimmed to drawing specifications.
Advanced CNC router equipment and two 5'x10' trimming centers deliver accurate, repeatable contour cutting, edge finishing, and precision drilling for thermoformed and fabricated plastic parts across short-run and high-volume production.
Custom molds and tooling using aluminum, polyurethane, and CNC-milled wood patterns. We support prototypes through full production tooling, with CNC trim fixtures, drill fixtures, and threaded inserts tailored to your specifications.
Rapid prototypes from low-cost wood or polyurethane tooling, machined to print specifications in just weeks. Ideal for design review and functional evaluation before committing to full production tooling and manufacturing runs.
Our 4'x7' Rotary Thermoforming machine runs 2.5x faster than standard single-station machines, enabling cost-effective, quality-controlled high-volume production from thousands of parts with competitive pricing and consistent output.
Our sales and engineering team—including Brad and Cody Hill—reviews your product requirements and recommends the optimal plastic material based on cost, impact resistance, durability, chemical resistance, and environmental conditions specific to your Colorado application.
