Qiaosen Machinery ST Series Open Single-Point Precision Punch Press Press Release

Introduction

Q1 What are core structural advantages and laboratory test data of ST series?

1. Frame: Integral thick steel plate welded frame with thermal stress relief treatment. Full-load frame deformation ≤0.02mm, far below industrial common standard.
2. Crankshaft: 42CrMo high-strength alloy steel, Rockwell hardness HRC 52–56, 1.3× higher structural strength and 2.1× longer fatigue life than ordinary 45# steel crankshaft.
3. Precision performance: Slider parallelism ±0.015mm, verticality ±0.02mm; 0.1mm fine die adjustment precision. Max speed up to 150 strokes per minute.
4. Safety system: Dual solenoid valve, pneumatic brake and mechanical overload protection. Emergency shutdown within 0.03s under 120% overrated load.
5. Durability: 72-hour continuous stamping test achieves 648,000 cycles with zero downtime, dimensional fluctuation ≤0.02mm, 40% lower mold wear rate.

Q3 Data-driven purchasing selection suggestions

• Small workshops & light stamping (≤80T): Choose ST-45/60/80. Compact footprint, low investment, easy operation for small-batch hardware processing.
• Medium mass production (80T–200T): Select ST-110/160/200. High rigidity & stable precision, ideal for auto hardware and furniture parts continuous stamping.
• Heavy-duty large workpiece forming (≥200T): Opt for ST-200/315. Super load-bearing performance for thick steel plate and large structural component stamping.
• Automatic production line matching: Fully compatible with Qiaosen GO 2-in-1 straightener and MT material rack for seamless integrated feeding solution.

Q4 Real customer on-site operation data

1. Local hardware factory (ST-80): 11.5h daily operation, defective rate reduced from 3.1% to 0.4%, monthly power cost saved 1120 RMB vs old equipment.
2. Auto parts enterprise (ST-160): 12-month continuous production with only 0.012mm precision attenuation, 38% lower annual maintenance cost.
3. Electronic component workshop (ST-110): Stable precision control matches thin metal terminal stamping, production efficiency improved by 22%.
