Precision Finishing for Thermoformed Plastic Parts — Made in USA

Thermoforming creates the shape. 5-Axis CNC trimming delivers the precision.

After vacuum forming, pressure forming, twin sheet forming, or compression thermoforming, accurate trimming is critical to ensure repeatability, fit, and final part quality. At Om Raj Tech, we represent Formed Solutions Inc, where thermoformed components are finished using six in-house 5-axis CNC machines, all operating in Michigan, USA.

This capability allows us to deliver clean edges, tight tolerances, and production-ready parts—not just formed shells.

    Why CNC Trimming Matters After Thermoforming

    Thermoformed parts exit the press with excess material around the perimeter and uncut openings. While hand trimming can work for prototypes or very low volumes, it introduces variability as volumes increase.

    To maintain consistent quality and on-time delivery, we rely on automated 5-axis CNC trimming for production programs.

    5 axis CNC trimming ensures:

    • Repeatable part geometry

    • Accurate hole locations and cutouts

    • Clean, professional edges

    • Reliable fit during assembly or installation

    Our 5-Axis CNC Trimming Capability

    Our facility is equipped with 6 dedicated 5-axis CNC machines manufacturers, reflecting advanced CNC capabilities designed specifically to support thermoformed plastic components and CNC plastic parts of varying sizes and geometries, including complex CNC-machined plastic components.

    What We Trim Using CNC Services

    • Outer perimeters on CNC machining plastic parts

    • Holes and cutouts

    • Slots, windows, and access openings for accurate CNC molded and thermoformed components

    • Complex 3D contours

    • Mounting and attachment locations

    The 5-axis capability allows the cutting head to approach the part from multiple angles, ensuring high-precision trimming for CNC machining plastic parts, even on deep draws or complex shapes, while supporting advanced CNC molding and finishing requirements without changing part integrity.

    Improving Quality & Scalability: From Hand Trimming to 5-Axis CNC Trimming

    Many thermoformed plastic programs begin with hand trimming, especially during prototyping or early production. Hand trimming can be effective at low volumes—but as demand increases, it often becomes the largest source of variability, rework, and delivery risk.

    This is where 5-axis CNC trimming for thermoformed plastics becomes a game changer.

    The Challenge With Hand-Trimming at Scale

    Customers relying on hand-trimmed thermoformed components often experience:

    • Inconsistent edge quality from part to part

    • Variation in hole locations and cutout dimensions

    • Increased rework and scrap rates

    • Slower production as volumes grow

    • Difficulty maintaining cosmetic consistency

    • Dependence on individual operator skill

    As volumes increase, these issues directly impact assembly fit, product appearance, and delivery schedules.
