Features:
- Uses carbon brushes to conduct electricity to the motor.
- Lower cost, easy to repair.
- However, the brushes wear out over time and require periodic replacement.
Advantages: Suitable for small workloads and small to medium-scale production.
Disadvantages: Less durable than brushless models, prone to overheating with prolonged use.
b. Brushless Electric Screwdrivers
Features:
- Utilizes a permanent magnet motor without carbon brushes.
- High durability, quiet operation, low maintenance.
- Higher price.
Advantages: Suitable for modern industrial production lines and large workloads.
Disadvantages: Higher initial investment cost.
c. Battery Electric Screwdrivers
Features:
- Flexible, not dependent on a power source.
- Suitable for mobile work, construction, or areas where power access is limited.
Advantages: Convenient, compact, and suitable for on-site assembly.
Disadvantages: Requires frequent battery charging; typically less powerful than direct electric models.
d. Automatic Electric Screwdrivers (Integrated Screw Feeder)
Features:
- Integrated automatic screw feeder to enhance productivity and reduce errors.
- Suitable for mass production lines.
Advantages: Increases work speed and reduces manual operations.
Disadvantages: High cost and requires regular maintenance; potential for screw jamming.
2. Criteria for Selecting the Appropriate Electric Screwdriver
To choose an electric screwdriver that best meets your production needs, please consider the following criteria:
a. Working Environment
- Industrial production lines: Opt for brushless models or automatic screwdrivers with integrated screw feeders to optimize efficiency.
- Mobile assembly projects: Cordless models are suitable due to their high mobility.
- Electronics manufacturing, clean rooms: Select screwdrivers with anti-static (ESD) features to protect sensitive components.
b. Torque Precision
- Products requiring high precision, such as electronic components and precision mechanical products, need screwdrivers with stable torque control.
- Brands like HIOS and Nitto Seiko are often highly regarded for torque accuracy.
c. Power and Usage frequency
- Continuous, high-intensity work: Choose brushless models with high power.
- Light-duty, infrequent tasks: Brushed or cordless models are cost-effective choices.
d. Additional Features
- Auto shut-off when the desired torque is reached to prevent over-tightening and product damage.
- Screw counting and error detection features to enhance quality control.
- Models with integrated vacuum suction or automatic screw feeders are suitable for large-scale production lines.
3. Reliable Electric Screwdriver Brands
a. HIOS (Japan)
- Renowned for high durability and precise torque control.
- Popular series include: HIOS BLG, HIOS CL, HIOS BL, HIOS VB, and HIOS VZ.
b. Nitto Seiko (Japan)
- Focuses on automatic models.
- High precision and stable torque control technology.
