CNC Turning Custom Fabrication Machining Parts

Our products are produced according to the customer’s drawing or sample; all parts are not in stock, customized only!

CNC Turning Custom Fabrication Machining Parts are high-precision PTFE components manufactured strictly according to customer drawings or samples. All products are fully customized with no stock available, ensuring each part meets specific application requirements.

PTFE (Polytetrafluoroethylene) is widely used as a gasket and sealing material due to its exceptional chemical resistance, low friction coefficient, and stability across extreme environments. It is also classified as a food-grade material in most cases, making it suitable for medical and food processing industries.

We provide a wide range of PTFE machined parts, including gaskets, seals, liners, and complex custom-shaped components for demanding industrial applications.

PTFE Material Types

• Virgin PTFE
  Pure material with excellent chemical resistance and electrical insulation properties
• Filled PTFE
  Enhanced with additives (glass fiber, carbon, graphite, etc.) to improve wear resistance and mechanical strength
• Expanded PTFE (ePTFE)
  Flexible and highly compressible, ideal for sealing and gasket applications

Manufacturing Capabilities

• CNC Turning Range:
  φ0.5mm – φ300mm × 3000mm
• CNC Milling Range:
  510mm × 1020mm × 500mm
