16-Ton Drawing Force Triple-Line Precision Cold Drawing Machine – Triple Output, One Compact Platform

FangRong introduces a three-line precision drawbench with 16 tons of drawing force per line – delivering ±0.02 mm accuracy, independent line control, and up to 3× productivity for small and medium-diameter tubes and bars.

DONGGUAN, China – October 27, 2026 – FangRong Precision Machinery today highlighted its 16-ton drawing force triple-line precision cold drawing machine, a high-output solution designed for manufacturers of small and medium-diameter metal tubes and bars. The machine combines three independent 16-ton drawing lines in a single integrated platform, enabling simultaneous production of the same or different products while maintaining the dimensional accuracy and surface quality required by automotive, medical, HVAC, and precision engineering markets.

Why 16 Tons × 3 Lines?

A 16-ton drawing force per line is ideally suited to small and medium-diameter tubes and bars – typically 4–30 mm for tubes and 4–25 mm for bars. This force level provides sufficient reduction capability for stainless steel, copper, brass, aluminum, and low-alloy carbon steels, while avoiding the energy overhead and floor-space requirements of larger single-line drawbenches. By combining three 16-ton lines into one machine, FangRong delivers a unique balance of productivity, precision, and cost efficiency.

Key Technical Specifications – 16-Ton Triple-Line Precision Cold Drawing Machine

Independent Line Control – Maximum Flexibility

Each of the three lines operates autonomously, with its own die box, gripping system, and servo-hydraulic control. This enables:

• High-volume production – all three lines running the same product for maximum output

• Mixed production – different sizes or materials on each line simultaneously

• Independent start/stop – one line can be serviced while the others continue running

• Quick changeover – recipe recall for each line in under 5 minutes

Core Technologies for Precision and Surface Protection

• Closed-loop force and position control – real-time adjustment for ±0.02 mm dimensional accuracy

• DLC-coated or polished carbide dies – prevents galling and ensures a bright surface finish

• Precision-guided mandrel support – prevents ovalization and ensures uniform wall thickness in tubes

• Padded gripper jaws – gentle clamping without surface marking

• Quick-change die and mandrel systems – fast size transitions with minimal downtime

• Optional in-process laser measurement – continuous OD and wall thickness verification with full data logging

Materials Processed

• Carbon steel, alloy steel (1010, 1020, 1045, 4140)

• Stainless steel (304, 316, 17-4 PH)

• Aluminum (6061, 6063, 7075)

• Copper, brass (C11000, C12200, C36000)

• Titanium (Grade 2, Grade 5)

Critical Applications

Real-World Example – Copper and Brass Tube Producer

A manufacturer supplying copper and brass tubes to HVAC and plumbing markets operated three separate 16-ton single-line drawbenches, requiring three operators and occupying 38 m² of floor space. After installing a FangRong 16-ton triple-line precision cold drawing machine:

Payback period: 13 months.
