Custom CNC Machined PTFE Insulation Structural Parts for Semiconductor Equipment
Quick detail
These custom PTFE components are precision CNC machined for semiconductor processing equipment. Featuring curved profiles, large hollow cavities, threaded sections and locating holes. PTFE material delivers excellent high-temperature resistance, chemical inertness and electrical insulation. Tight dimensional tolerance ensures stable performance in corrosive semiconductor process environments.
Product description
This set of PTFE structural components serves as insulating support and flow guiding parts inside wet processing semiconductor equipment. PTFE is selected for its outstanding resistance to strong acid and alkali, non-contamination and dielectric insulation property, which avoids metal ion pollution to silicon wafers. The complex curved, hollow and deep cavity structure requires multi-axis CNC machining. PTFE is soft and prone to chipping during cutting. Our technicians adopted optimized low-feed cutting parameters and special tool path strategy to eliminate edge chipping and maintain smooth surface finish. All dimensions are inspected by coordinate measuring machine before shipment to meet the strict cleanliness requirement of semiconductor production lines.
