SS Pipe Bending Machines

Small pipe bending machines are lightweight units designed for small-diameter tubes (typically ≤50 mm). They are widely used in furniture, decoration, automotive parts, fitness equipment, and electrical installation.

1. Manual/Electric Hydraulic Type

50. Bending Capacity: φ16–50 mm (wall thickness ≤3 mm)
50. Bending Angle: 0–180°
50. Weight: 25–40 kg, portable or equipped with wheels for easy mobility
50. Power Supply: Single-phase 220 V (no three-phase required)
50. Applications: Ideal for on-site construction or repair work
50. Price Range: RMB 700–900

Limitations: Requires manual die change for each bend; angle adjustment relies on mechanical scales, so consistency in batch production is limited.

2. Compact CNC Models

50. Bending Capacity: φ6–42 mm (wall thickness ≤3 mm)
50. Feeding Accuracy: ±0.1 mm
50. Bending Accuracy: ±0.1°
50. Machine Dimensions: Approx. 0.9 m × 0.5 m × 0.9 m
50. Weight: 200–350 kg
50. Control System: 3–5 servo-driven axes, enabling feeding, rotation, and bending in a single cycle
50. Features: USB/Ethernet interface, CAD file import, storage capacity ≥500 programs
50. Price Range: RMB 20,000–40,000; German transfluid MB642 (φ6–42 mm) priced around RMB 80,000–100,000

Typical Applications: Office chair backrest frames, automotive brake/oil pipes, air conditioning connection tubes, and trolley handles.

3. Desktop Multi-Function Electric Type

50. Bending Capacity: φ25–38 mm (wall thickness ≤2 mm)
50. Motor Power: 1.5–2.2 kW
50. Weight: 80–120 kg, suitable for tabletop operation
50. Price Range: RMB 3,000–6,000
50. Features: Quick die change, suitable for small-batch, multi-spec production. Optional “platform + roller” structure allows round and arc rolling, commonly used for decorative railings and greenhouse frames.

Selection Guidelines

Always confirm the “maximum pipe outer diameter × wall thickness” and the “minimum bending radius” before choosing a machine. For stainless steel pipes, the required tonnage is typically 20–30% higher than for carbon steel pipes.
