ST Deep‑Throat Series – High‑Rigidity Extended‑Bed Punch Press for Wide Progressive Die & Large‑Part Stamping

2026-05-19

1. Product Overview

Dongguan Qiaosen Machinery launches the ST Deep‑Throat Series, an upgraded version of the standard ST series with extended throat depth and wider bolster plate, specially developed for wide progressive dies, large‑size metal brackets, cabinet hardware and automotive structural parts that require deeper feeding space.

Available in both mechanical and servo (sv) versions, covering 80–200 tons, this series solves the bottleneck of insufficient working space of ordinary C‑frame presses, maintaining JIS Class 1 precision and high‑rigidity one‑piece frame structure.

Table 1: Core Technical Parameters of ST Deep‑Throat Series

Model	Type	Nominal Pressure (Ton)	Throat Depth (mm)	Full‑Load SPM	Repeat Positioning Accuracy	Energy Consumption (kWh/h)
ST‑80DT	Deep‑throat Mechanical	80	450	60–100	±0.006 mm	0.65
ST‑110DT	Deep‑throat Mechanical	110	500	50–90	±0.006 mm	0.75
STA‑160DT‑sv	Deep‑throat Servo	160	550	20–100	±0.003 mm	0.68

2. Key Advantages & Professional Q&A

Q: What makes ST Deep‑Throat Series different from standard ST presses?

A: It features 30%‑40% deeper throat depth and wider bolster, allowing installation of wide‑format progressive dies and long workpieces. The reinforced side frame avoids deflection under eccentric load, ensuring stable parallelism even with large‑area stamping.

Q: Which industries are suitable for ST Deep‑Throat presses?

A: Cabinet hardware, electrical enclosures, large automotive brackets, solar energy structural parts, home appliance long‑size components and wide progressive die mass production.

3. Real‑World User Case & Performance Data

A home‑appliance hardware manufacturer in Guangdong purchased 2 units of STA‑160DT‑sv deep‑throat servo presses for long‑size shell stamping. After 11‑month two‑shift production, significant improvements were recorded.

Table 2: Before‑and‑After Production Performance Comparison

Indicator	Ordinary Standard‑Throat Press	Qiaosen STA‑160DT‑sv	Improvement
Maximum Die Width Compatibility	≤600 mm	≤900 mm	Wider production range
Product Defect Rate	0.72%	≤0.025%	↓96.5%
Daily Output per Machine	8,100 pcs	12,400 pcs	↑53%
Mold Service Life	110,000 pcs	350,000 pcs	↑218%
Payback Period	—	8 months	Fast ROI

4. Conclusion

Qiaosen ST Deep‑Throat Series perfectly supplements the standard ST product line, providing deep‑space stamping capacity with high rigidity and precision. Both mechanical and servo options meet general‑purpose and intelligent production needs for large‑size and wide‑die applications.

It is the ideal solution for manufacturers upgrading from standard C‑frame presses to handle larger workpieces and wider progressive dies.
