In today’s era of global industrial automation, the smart electric screwdriver (also known as an intelligent electric screw gun) is no longer just a simple replacement for manual tools. It has evolved into an intelligent production unit that integrates precision mechanics, sensor technology, and digital control. It is widely used in industries such as 3C electronics, automotive parts, home appliances, and medical devices—where high precision and consistency in assembly are critical.

I. Clarify Your Core Requirements

Before comparing specific models, be sure to answer the following questions:

• What product are you tightening?
  (e.g., phone motherboard, laptop casing, automotive central control screen, precision instrument)

• What are the screw specifications?
  (including screw type, material, length, and diameter)

• What is the required torque range?
  (This is the most critical technical parameter, usually in N·m or cN·m)

• What is the required production takt time?
  (i.e., how many tightening points per minute)

• What systems does it need to integrate with?
  (standalone workstation or integrated into an automated line or robotic arm?)

• What is your budget range?

Once you’ve clarified the above, you’re already halfway to making the right choice.

II. Focus on Five Key Selection Criteria

① Torque Range & Precision Control

Torque is the most core parameter of a smart screwdriver and directly determines assembly quality.

Danikor’s smart screwdriver lineup covers torque ranges from 0.02 N·m to 480 N·m.

• Sensor-based models offer a precision of 6σ ±5%

• Current-based models offer 6σ ±7.5%
  Suitable for a wide range of applications.

② Speed & Efficiency

Speed affects tightening efficiency. On high-takt lines, high speed reduces cycle time. However, for small screws or plastic parts, excessive speed may cause slipping or damage. Danikor supports multi-speed control, allowing flexible settings based on process needs—balancing speed and quality.

③ Data Traceability & MES Integration

In the context of Industry 4.0 and smart manufacturing, data is invaluable.

• Real-time monitoring: Record torque, angle, time, etc. for every tightening operation

• Result judgment: Automatically determine pass/fail (OK/NG) with visual/audio alerts

• Data output: Upload via I/O, RS485, or Ethernet to a host or MES system for full traceability

Danikor smart screwdrivers fully support these features, providing a solid data foundation for your digital factory.

④ Reliability & Durability

Production equipment must run 24/7. Consider:

• Housing design and materials

• Core motor type (e.g., brushless servo motor)

• Lifespan of key components

With strong R&D and manufacturing capabilities, Danikor products are known for high reliability and long service life, meeting the demands of harsh industrial environments.

⑤ Ergonomics & Ease of Use

For handheld applications:

• Weight, balance, and grip comfort directly affect operator fatigue

• Lightweight, low-vibration designs improve ergonomics

• Simple UI and easy parameter setup reduce training time and usage barriers
