Precision 4-Axis CNC Machining for Custom Plastic Parts
For engineers and product developers requiring complex plastic geometries with minimal setups, plasticpartsmfg provides high-precision 4-axis CNC machining services. Based in Shenzhen, we bridge the gap between initial prototyping and functional low-volume production, delivering parts that meet stringent engineering specifications.
The addition of a rotary axis allows us to machine cylindrical features, complex slots, and multi-face components with greater efficiency and superior positional accuracy compared to standard 3-axis machining.
Our 4-Axis Machining Capabilities
By utilizing 4-axis CNC technology, we reduce the need for manual repositioning, which minimizes tolerance stack-up and improves the overall consistency of your parts.

Why Choose 4-Axis CNC for Your Project?
4-axis machining is the ideal solution when your design includes features that cannot be reached or accurately aligned in a single 3-axis setup.
Start Your ProjectReduced Setups
Machining multiple sides of a component in one cycle decreases cycle time and lowers the risk of human error during indexing.
Improved Consistency
By minimizing repositioning, we ensure that side holes, slots, and curved surfaces maintain precise alignment with primary datum features.
Complex Geometry
Easily produce complex contours, radial patterns, and cylindrical features that require continuous or indexed rotation.
