STE‑80sv Servo Press Boosts High‑Speed Progressive Die Stamping for Electronic Hardware

2026-05-14

1. Project Background & Customer Pain Points

A precision electronic hardware manufacturer based in Shenzhen specializes in producing 0.2–1.0 mm cold‑rolled steel terminals and shrapnel for consumer electronics. Its main production mode is high‑speed progressive die stamping. Before upgrading, the workshop used ordinary single‑crank servo presses, suffering from obvious bottlenecks: insufficient stamping speed, unstable bottom dead‑center precision, high defect rate, short mold service life and low daily output, which could not meet large‑volume order requirements.

To solve these problems, the customer purchased 3 units of Qiaosen STE‑80sv eccentric gear‑type servo presses in mid‑2024 to renovate the production line.

2. Product Advantages & Main Parameters

Qiaosen STE series adopts eccentric gear transmission + direct servo drive, featuring high speed, low vibration and stable precision, especially suitable for thin‑plate high‑speed continuous stamping.

Table 1: Core Technical Parameters of STE‑80sv

Item	Specification
Nominal Pressure	80 Ton
Full‑Load Stable SPM	70–100
Repeat Positioning Accuracy	≤±0.003 mm
Slider Parallelism	≤0.015 mm/300mm
Unit Energy Consumption	0.66 kWh/h

3. Implementation & Measurable Results

After 10 months of continuous two‑shift operation (12 hours per day), the production performance was comprehensively improved, as shown in the comparison table below.

Table 2: Production Performance Before vs After Upgrade

Indicator	Ordinary Single‑Crank Servo	Qiaosen STE‑80sv	Improvement
Full‑Load Stamping Speed	60–70 SPM	70–100 SPM	+43%
Product Defect Rate	0.65%	≤0.02%	↓96.9%
Daily Output per Machine	28,000 pcs	40,200 pcs	+43.6%
Mold Service Life	180,000 pcs	660,000 pcs	+267%
Payback Period	—	7 months	Fast ROI

4. Case Conclusion

This case proves that Qiaosen STE servo series, with eccentric gear high‑speed transmission structure, perfectly matches the high‑volume progressive die stamping needs of electronic hardware parts. Compared with conventional single‑crank servo presses, it delivers higher speed, better stability, lower energy consumption and longer mold life, effectively reducing production costs and improving core competitiveness for precision electronic manufacturers.
