Automatic Ferrite Inductor Coil Winding Machine

Why Automation in Inductor Manufacturing Is Essential

1. Market Demand

The rapid adoption of Switched Mode Power Supplies (SMPS), renewable energy systems, LED lighting, electric vehicle chargers, and communication equipment has created an unprecedented demand for inductor coils. EE series inductors, especially in sizes EE10 to EE25, are used in millions each year across industries.

2. Limitations of Manual Production

• Inconsistent winding quality due to human error.

• High dependency on skilled operators.

• Limited daily output (one operator requires ~30–35 seconds per coil).

• Increased production costs due to labor dependency.

3. Global Competitiveness

International manufacturers are moving towards fully automated mass production. To remain competitive, Indian manufacturers must adopt automation to ensure scalability, quality, and lower per-unit costs.

4. Precision Requirements

Modern electronics demand tight tolerance in inductance values. Small deviations in winding turns, wire tension, or placement can result in defective components. Automation ensures repeatable accuracy.

In summary, automation is no longer optional—it is a necessity for any serious player in the electronics component manufacturing sector.

Technical Specifications

Working Principle – Step by Step

1. Bobbin Loading
   The operator places blank bobbins into the loading plate. No manual fixing into spindles is required.

2. Automatic Loading into Spindles
   The machine automatically transfers bobbins from the plate into spindle fixtures.

3. Winding Process

   • 12 spindles begin winding simultaneously.

   • Wire tension and turns are controlled by servo motors.

   • Winding programs can be customized for different designs.

4. Optional Twisting

   • For ultra-thin wires, twisting prevents breakage.

   • The twister unit can be added on demand.

5. Optional Taping

   • Coils can be wrapped with tape for insulation.

   • Automated taping ensures uniform finish.

6. Wire Cutting

   • Pneumatic nipper cutter trims the wire.

   • Heavy-gauge wires are handled safely.

7. Unloading

   • Finished coils are unloaded automatically.

   • Machine resets for the next cycle

Cycle Time & Productivity

• Cycle Time: 15–20 seconds for 12 coils.

• Output Per Hour:

  • At 15 seconds/cycle → 2880 coils/hour.

  • At 20 seconds/cycle → 2160 coils/hour.

• Daily Production (16 hours):

  • Between 34,560 and 46,080 coils/day.

This makes the machine ideal for mass production requirements.

ROI (Return on Investment)

Manual Winding (1 Operator)

• Cycle time: 30–35 seconds per coil.

• Hourly Output: ~103–120 coils.

• Daily Output (16 hours): ~1,648–1,920 coils.

Automatic Winding (Deptronics 12 Spindle)

• Cycle Time: 15–20 seconds for 12 coils.

• Hourly Output: 2,160–2,880 coils.

• Daily Output: 34,560–46,080 coils.

Efficiency Comparison

• Automatic machine produces 22× more coils per day.

Example ROI Calculation

• Average coil value = ₹2.5 per piece.

• Manual Production: 1,800 coils/day × ₹2.5 = ₹4,500/day revenue.

• Automatic Production: 40,000 coils/day × ₹2.5 = ₹1,00,000/day revenue.

Thus, depending on configuration and production demand, ROI can be achieved within 6–12 months.
