Forming Thread Tap
Chip-less Threading Technology
Deforms material via cold flow forming instead of cutting, eliminating chips and debris.
Superior Thread Strength
Compressed grain structure increases fatigue resistance by 30% vs. cut threads.
Extended Tool Life
TicN/TiN coatings withstand 600°C, providing 3-5x longer life in abrasive materials.
Blind Hole Optimization
No chip evacuation needed – ideal for deep or blind holes (e.g., engine blocks, housings).
High-Speed Compatibility
Polished flutes reduce friction, enabling 50% faster tapping speeds than cutting taps.
Material Versatility
Works on non-ferrous metals (aluminum, brass), soft steel (< 1200 MPa), and plastics.
Reduced Tool Breakage
Reinforced core (60-65 HRC) resists fracture under high forming torque
TYPICAL APPLICATION SCENARIOS
Automotive Fastener Production
Forming high-strength threads in alloy wheels, transmission housings, and fuel injectors.
Electronics Manufacturing
Chip-less threading of aluminum smartphone casings and copper heat sinks.
Aerospace Components
Creating fatigue-resistant threads in titanium landing gear parts (requires coated taps).
Medical Device Assembly
Burr-free threading of stainless steel surgical tools and implant housings.
HVAC & Plumbing Systems
Sealing threads in brass water valves without clogging from metal chips.
High-Volume CNC Machining
Uninterrupted production of aluminum automotive parts (e.g., cylinder heads).
