TUNGLIH designs and manufactures pneumatic screwdrivers for continuous-duty factory lines. As a Shenzhen-based OEM/ODM manufacturer, we focus on precise, adjustable torque, repeatable shut-off, and high uptime. Our core range centers on compact pistol-grip models (lever start or push-to-start) with torque capacity up to 80 Nm for electronics, automotive, appliances, furniture, and general manufacturing. These tools integrate smoothly with automatic screw feeders to stabilize takt time.
High-precision, adjustable torque with repeatable performance
18+ years of R&D and production (est. 2006)
In-house parts manufacturing for reliable quality and fast service
Proven supply to Foxconn, Huawei, and BYD
OEM/ODM customization and certification support on request
The pistol-grip format combines maneuverability and control for manual stations. Balanced housings, low trigger force, and light weight reduce fatigue. Tools are compatible with torque arms, balancers, and automatic feeders to improve accuracy and throughput.
Select a start mode to match cycle time and control needs.
| Start Mode | Best For | Notes |
|---|---|---|
| Lever start | Delicate or variable joints | Fine control; fewer accidental starts |
| Push-to-start | Repeatable stations | Faster activation and consistent timing |
Shut-off clutch: Highest torque accuracy for hard joints (metal-to-metal)
Slip clutch: Protects soft joints (plastics, wood) from over-tightening
Direct drive: Prioritizes speed when the torque window is wider
Define target torque from screw size and joint materials. Choose RPM to meet takt time without sacrificing control. Ensure stable air pressure and adequate flow with proper FRL, hose ID, and fittings. Confirm ergonomics (weight, balance, grip) and plan reaction management for long shifts.
Air screwdrivers from TUNGLIH support electronics housings and modules, automotive sub-assemblies, appliance panels and plastics, furniture and woodworking, and general machinery tasks at high cycle rates.
We tailor torque ranges, clutches, handles, housings, and branding to your standards. Our process covers requirements capture, feasibility, DFM, pilot runs, and validation. NDA is available for confidential projects.
Share your torque range, screw size and joint type, desired RPM, preferred start mode and clutch, air supply details, and quantities. TUNGLIH will recommend models, samples, and lead times to support your assembly line with reliable tools and responsive service.
