As the economy grows rapidly, assembly operations—which account for 30–70 % of total product manufacturing workload and about 30–50 % of total cost—are gradually shifting from manual to automatic assembly. Recent advances in motor-speed control and torque-control technologies have accelerated the transition from pneumatic to fully automatic, high-precision “intelligent” electric screwdrivers. These tools achieve accurate torque, angle, or yield-point control and have become common in the mechanical, electronic, and automotive-component industries. Consequently, many manufacturers now offer cost-effective intelligent drivers. One leading domestic producer is Danikor (Wuxi Danikor Automation Technology Co., Ltd.).

Danikor specializes in intelligent screwdriver R&D. Recognized for quality and service, Danikor maintains long-term partnerships with numerous domestic automotive OEMs and tier-one suppliers. 

Product lines include:

• Machine-mount straight-handle intelligent drivers
  Model range: 4500 M ~ 1050 N
  Screw sizes: M1 ~ M20
  Torque range: 0.05 N·m ~ 105 N·m

• Hand-held straight-handle intelligent drivers
  Model range: 1000 M ~ 0100 N
  Screw sizes: M1 ~ M8
  Torque range: 0.02 N·m ~ 10 N·m

Danikor combines computer control and DC-servo technology with controllable torque tightening methods to design drivers for diverse applications. All tools can be configured as single-axis or multi-axis systems (suspended or fixed-frame) and integrated with host PCs or PLCs. Torque accuracy is ±7.5 %. Torque sensors in the driver provide real-time measurement and full process monitoring.
