CNC Trimming
Precision Thermoforming Finishing with 5-Axis CNC
& Punch Presses
At Tru-Form Plastics, we finish every part with accuracy and consistency. Our CNC trimming services are built around 5-axis CNC machining and precision punch systems, allowing us to deliver detailed finishes on even the most complex thermoforming plastics.
All heavy gauge parts undergo post-forming trimming to meet exact design specs. Using automated equipment and detailed trim fixtures, we create clean edges, repeatable geometries, and reliable performance across every unit.
Advanced CNC Trimming Capabilities
We operate a fleet of 5-axis CNC routers designed to handle custom trimming programs with tight tolerances and smooth motion. This process minimizes human error, improves cycle time, and supports quick adjustments when designs change.
Key advantages of CNC trimming include:
- Tight dimensional control for detailed cutouts and profiles
- Reduced defects and improved operator safety
- Faster processing compared to manual methods
- Consistent repeatability from part to part
- Flexibility for design revisions or small-lot runs
Punching & Fixture Support
In addition to routing, we use steel rule die punch presses for parts that require speed and simplicity in forming perforations, vents, or mounting points. These presses allow for efficient, high-volume finishing on both thin and heavy gauge parts.
To maintain part integrity, we use vacuum-hold fixtures that secure each form in place before trimming begins. This ensures each part is cut cleanly along the programmed path – no shifting, no guessing.
Built for the Full Thermoforming Process
Trimming is a critical step in the plastic thermoforming process, especially for programs that require precision fits, cosmetic edges, or downstream assembly. We apply the same attention to detail here as we do in mold building, forming, and packaging.
As part of our precision thermoforming services, our CNC trimming team works closely with engineering to validate trim paths, optimize fixture design, and meet customer quality expectations.
