Vacuum Forming
Custom thermoforming and vacuum forming using eight machines ranging from 2'x3' to 5'x9'. We form plastic sheets over precision molds to produce enclosures, trays, OEM parts, and more with fast turnaround and low-cost tooling.
Hill Plastics has delivered precision thermoforming and vacuum forming solutions since 1977. Serving manufacturers and OEMs across Washington and the broader Pacific Northwest, we offer custom thermoformed parts, plastic fabrication, CNC trimming, and mold making — all backed by over four decades of proven expertise and competitive pricing.
From vacuum forming and mold making to CNC trimming and high-volume production, we offer end-to-end custom plastic solutions.
Custom thermoforming and vacuum forming using eight machines ranging from 2'x3' to 5'x9'. We form plastic sheets over precision molds to produce enclosures, trays, OEM parts, and more with fast turnaround and low-cost tooling.
Full-service plastic fabrication including precision trimming, drilling, heat bending, bonding, and assembly. Our skilled team produces custom POP displays, industrial parts, and finished components to exact drawing specifications.
Advanced CNC router trimming with two 5'x10' trimming centers for primary and secondary operations. We deliver dimensionally accurate, clean-edge parts ready for assembly across short-run and high-volume production.
Custom mold fabrication using aluminum, polyurethane, and precision wood patterns. We support prototypes through production tooling with CNC-milled master patterns, ensuring fit, function, and easy design adjustments.
Rapid prototype production using low-cost wood or polyurethane tooling. Master patterns are typically machined and ready in just a few weeks, letting you evaluate design fit and function before committing to full production.
Our 4'x7' rotary thermoforming machine runs 2.5x faster than standard single-station equipment, enabling cost-effective, quality-controlled high-volume production from thousands of parts with competitive pricing.
Our sales and engineering team — Brad and Cody Hill — work directly with you to evaluate your product requirements, recommend the best thermoplastic materials (ABS, HDPE, PETG, KYDEX, and more), and define tooling design for your application and environment.
