Precision Plastic Swiss Machining Services
Plasticpartsmfg provides custom Swiss-type CNC machining for small, long, and slender plastic components that require high precision and efficient production. Based in Shenzhen, our facility is equipped to handle complex geometries for miniature parts used in medical devices, electronics, and industrial equipment.
A sliding headstock and guide bushing support the workpiece close to the cutting tool, eliminating deflection and ensuring consistent dimensional control where standard CNC turning falls short.

Technical Advantages
Why Choose Swiss Machining for Plastic Parts?
For small-diameter plastic components, Swiss machining offers several technical advantages over conventional CNC turning.
01
High Aspect Ratios
Guide bushing support allows us to machine long, thin parts—shafts, pins, and needles—without the part bending or vibrating during the cut.
02
Tight Tolerances
We consistently achieve tolerances as tight as ±0.005 mm, which is essential for press-fit assemblies and precision medical components.
03
Surface Integrity
The stability of the Swiss process results in superior surface finishes, often reducing the need for secondary polishing.
04
Complex Geometry
With live tooling and sub-spindles, we can perform off-center drilling and milling on the same machine, reducing setup time and costs.
Materials
Engineering Materials We Machine
We work with a wide range of engineering and high-performance plastics. Material selection is critical in Swiss machining to ensure dimensional stability and prevent burr formation.
POM (Delrin / Acetal)
Excellent machinability and dimensional stability. Ideal for gears, bushings, and sliding parts.
PEEK
A high-performance polymer used for medical implants and aerospace parts requiring high temperature and chemical resistance.
Nylon (PA6 / PA66)
Known for wear resistance and strength; frequently used for spacers and insulators.
PTFE (Teflon)
Low friction and high chemical resistance, though requiring specialized handling due to its softness.
PC (Polycarbonate)
Used for transparent precision components or parts requiring high impact strength.
PPS & PPSU
Selected for high-heat applications and sterilization environments in medical or laboratory settings.
