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.
