Thermoforming, Fabrication, and Tooling Under One Roof
Since 1977, Hill Plastics has supplied OEM manufacturers with custom thermoformed parts, enclosures, and fabricated components. Our Lewisville, Texas facility brings thermoforming, plastic fabrication, CNC trimming, quality control, and project support together under one roof, with tooling support available based on project requirements.
Four Capabilities, One Accountable Team
Each service below stands on its own, but most projects move through several of them. Keeping design, tooling, forming, and finishing in one shop removes handoffs and protects your timeline.
Thermoforming / Vacuum Forming
Eight thermoforming machines from 2 x 3 up to 5 x 9 feet, plus a 4 x 7 rotary machine for high volume production. Cost effective parts from prototype through full production runs.

One roof. One accountable team. CAD file to finished part.
Thermoforming, plastic fabrication, CNC trimming, quality control, and project support are coordinated through one team to reduce unnecessary handoffs and keep production moving.
Over 20,000 square feet built for production
Established in 1977 and based near Dallas and DFW, Hill Plastics provides plastic thermoforming, vacuum forming, and fabrication for aerospace, telecommunications, industrial enclosures, marine, medical, and other OEMs and entrepreneurs. Our Lewisville, Texas facility holds over 20,000 square feet of manufacturing space.
We run single station thermoforming machines from 2 x 3 to 5 x 9 feet, a 4 x 7 rotary thermoforming machine with a cycle time 2.5 times faster than standard single station machines, and two 5 x 10 CNC trimming centers for primary and secondary trim operations.
Design and CNC interface are handled in SolidWorks. For prototypes and pre production we use low cost wood or polyurethane tooling, and aluminum tooling for production parts. Our staff carry a minimum tenure of 20 years as industry professionals and hold molding and trim details to print specifications and tolerances.
