From precision trimming and contour cutting to complex multi-axis machining, we deliver accurate, assembly-ready plastic parts for every application.
Precision CNC trimming and cutting of thermoformed and fabricated plastic parts to exact drawing specifications using two 5'x10' CNC trimming centers, ensuring clean edges, dimensional accuracy, and repeatable production quality.
Advanced contour routing and edge finishing services that produce smooth, burr-free perimeters on complex plastic profiles, eliminating manual labor and ensuring parts meet tight dimensional tolerances for OEM and industrial applications.
Accurate CNC-controlled drilling, hole placement, and fastener preparation — including threaded inserts and riveting provisions — to produce fully assembly-ready plastic components that meet engineering print specifications.
Comprehensive secondary operations including heat bending, bonding, assembly, and fastener installation performed after CNC routing to deliver fully finished plastic parts ready for integration into enclosures, guards, and displays.
CNC-milled master patterns and tooling from wood, polyurethane, and aluminum materials, used to support thermoforming mold development, prototype review, and production tooling for custom plastic forming applications.
Scalable 5-axis CNC routing support from initial prototype runs through high-volume production, leveraging SolidWorks CAD/CNC integration and a 20,000+ sq ft facility to meet any quantity requirement efficiently.
Our Lewisville engineering team reviews your part drawings and requirements using SolidWorks CAD software to generate precise CNC toolpaths. We verify geometry, tolerances, and material compatibility before any cutting begins, preventing costly errors downstream.

5-axis CNC routing allows the cutting tool to move along five simultaneous axes — three linear (X, Y, Z) and two rotational — enabling complex contours, undercuts, and multi-face features to be machined in a single setup. Standard 3-axis routing requires repositioning the part between operations, which introduces alignment errors. 5-axis routing delivers superior accuracy, cleaner edges, and reduced cycle times for complex plastic components.
