Advanced hydraulic drawbenches deliver ±0.015–0.02 mm accuracy, Ra ≤0.2–0.4 µm surface finish, and longer die life – reducing scrap, maintenance, and energy costs in high-value tube and bar production.


DONGGUAN, China – September 30, 2026 – In metal tube and bar manufacturing, the purchase price of a cold drawing machine is only one part of the cost equation. Scrap rate, die life, energy consumption, labor requirements, and maintenance downtime often have a far greater impact on long-term profitability. FangRong Precision Machinery today highlighted how precision hydraulic cold drawing machines help manufacturers lower total cost of ownership (TCO) while achieving the tight tolerances demanded by aerospace, medical, automotive, and energy applications.

Why Hydraulic Precision Reduces Total Cost of Ownership

Hydraulic cold drawing machines use smooth, programmable force to pull tubes or bars through precision dies. Unlike chain-driven systems, hydraulic drawbenches eliminate pulsation and stick-slip vibration. This directly improves:

  • Surface quality – no chatter marks, fewer rejects

  • Dimensional consistency – ±0.015–0.02 mm accuracy

  • Die life – smooth force reduces wear and galling

  • Energy efficiency – variable-displacement pumps deliver power on demand

  • Process flexibility – infinitely variable speed for different alloys

For manufacturers processing high-value materials such as stainless steel, titanium, nickel alloys, copper, and aluminum, these benefits translate directly into lower cost per finished piece.

Automation Options That Further Reduce TCO

  • Automatic pointing machine – prepares tube/bar ends for smooth die entry

  • Magazine infeed – up to 2 tonnes capacity; reduces manual handling

  • In-line straightening – achieves ≤0.3 mm/m straightness without a second pass

  • Cut-to-length system – precision cutting with ±0.5 mm accuracy

  • Automatic stacking – damage-free collection and bundling

  • Data logging – full traceability for ISO, AS9100, and IATF audits


Real-World Example – Stainless Steel Tube Producer

A manufacturer of stainless steel hydraulic tubes processed 20 mm OD × 2 mm wall 304 tubes. Their chain-driven drawbench achieved only 0.6 mm/m straightness after drawing and required frequent die changes. After switching to a FangRong precision hydraulic drawbench with closed-loop control and an integrated straightener:
