Fully automated hydraulic drawbenches deliver ±0.02 mm dimensional accuracy, superior surface finish, and consistent mechanical properties for aluminum round, hexagonal, and square bars – ideal for aerospace, automotive, CNC machining, and electrical applications. Why Aluminum Bars Need Specialized Cold Drawing Aluminum bars (6061, 7075, 2024, 6063, etc.) are widely used in precision machining, structural components, and electrical conductors. Cold drawing enhances their prop

From square tubes to hexagonal bars, from asymmetric channels to custom extrusions – achieving ≤0.2 mm/m straightness without edge damage, twist residue, or surface marking. Why Special‑Shaped Profiles Are a Different Straightening Challenge Unlike round bars or tubes, special‑shaped profiles (non‑circular cross‑sections) carry multiple geometric defects simultaneously: Camber – bending in the horizontal plane Bow – bending in the vertical plane Twist – axial rotation along t

Not all straighteners are the same. Here is a practical guide to selecting the right automatic precision straightening machine for your material, profile, and output requirements. Where Do You Start? Walking into a straightening machine purchase without a clear framework often leads to over‑specification (paying for capacity you do not need) or under‑specification (reject rates stay high). Before contacting any supplier, answer these four questions: Question Why It Matters Wh

Four radially arranged hydraulic dies deliver excellent end concentricity, smooth surface finish, and fast cycle times – ideal for copper, brass, aluminum, steel, and stainless steel tubes in cold drawing lines. Why a Four‑Die Pointing Machine? The pointing operation is the critical first step in cold drawing – a poorly formed point leads to die damage, carriage slippage, and material waste. A hydraulic four‑die pointing machine uses four dies arranged radially around the tub

FangRong’s multi‑material precision straightener automatically adapts to the unique spring‑back, surface sensitivity, and ductility of copper, brass, and aluminum – delivering ≤0.2 mm/m straightness without tooling change. The Challenge: Copper, Brass and Aluminum Behave Completely Differently Straightening copper, brass and aluminum profiles on a single machine has traditionally been a compromise: Copper (soft, high ductility) – prone to scratching and galling; requires gent

FangRong’s integrated solution eliminates manual transfers, cuts labor by 60%, and ensures end‑to‑end traceability for precision tubes and bars. The Old Way: Three Machines, Three Operators, Countless Headaches Traditional cold drawing lines operate as disconnected islands: Pointing – Operator prepares ends, often with a separate swager or lathe. Drawing – Another operator feeds pointed material into the drawbench. Straightening – A third operator takes drawn stock to a separ

FangRong strengthens its footprint in the Indian non‑ferrous market with a dedicated drawbench line for electrical, plumbing, and precision engineering applications. DONGGUAN, China – June 13, 2026 – FangRong Precision Machinery has loaded and shipped a complete cold drawing solution for copper, brass, and bronze tubes and rods to a long‑standing partner in India. The containerized system includes a hydraulic drawbench, automatic pointing machine, and downstream straightening

Common straightening mistakes that damage corners, leave residual stress, or fail to remove twist – and the machine design changes that solve them. The Hidden Defects Left by Ordinary Straighteners Many manufacturers assume that if a profile looks straight to the eye, it is ready for machining or assembly. But special‑shaped profiles – channels, hexagons, asymmetric extrusions – often hide residual twist and edge stress that cause problems downstream: CNC machining rejects be

Advanced multi‑axis straightening technology delivers ≤0.2 mm/m straightness, twist correction, and surface integrity for square, rectangular, hexagonal, channel, angle, and custom‑extruded profiles – essential for aerospace, automotive, medical, and industrial applications. The Challenge of Straightening Special‑Shaped Metal Profiles Unlike round tubes or bars, special‑shaped profiles (non‑circular cross‑sections) suffer from combined geometric defects: camber (bending in mu

FangRong’s new generation straightening system delivers consistent ≤0.15 mm/m straightness for copper tubes – ideal for HVAC, refrigeration, plumbing, and medical gas lines. DONGGUAN, China – FangRong Precision Machinery has launched a fully automatic straightening machine specifically engineered for copper tube production.

Ideal for medical hypotubes, precision instrument shafts, fuel injection lines, and electronics components – delivering ±0.015 mm accuracy in a space‑saving, energy‑efficient design. Why a 10‑Ton Precision Hydraulic Drawbench? Not every application requires hundreds of tons. For manufacturers producing small‑diameter tubes and bars (2–25 mm), a 10‑ton precision hydraulic cold drawing machine offers the perfect balance of power, accuracy, and economy. Its smooth hydraulic forc

High‑precision hydraulic drawbench expands Indian customer’s capacity for non‑ferrous tube and bar production – serving electrical, plumbing, and industrial applications. DONGGUAN, China – June 6, 2026 – FangRong Precision Machinery today announced the shipment of a specialized cold drawing machine to a leading Indian manufacturer of non‑ferrous tubes and rods.

Advanced multi‑roll straightening technology delivers consistent ≤0.15 mm/m straightness, flawless surface finish, and dimensional accuracy for copper round bars, hexagons, and squares – essential for electrical connectors, busbars, valve components, and precision machining. Why Copper Bars Need Multi‑Roll Precision Straightening Copper bars (C11000, C12200, C36000, etc.) are widely used in electrical power distribution, switchgear, plumbing fittings, and precision‑machined c

Six radially arranged hydraulic dies deliver unmatched end concentricity, faster cycles, and smoother surface finish – ideal for stainless steel, titanium, high‑strength alloys, and precision cold drawing lines. Why Six Dies? Traditional pointing machines use two, three, or four dies. The six‑die hydraulic pointing machine distributes forming force more evenly around the tube or bar circumference, resulting in: Superior concentricity – ≤0.05 mm deviation, essential for thin‑w

Engineered to correct bends and twists in stainless steel, titanium, Inconel, and high‑strength alloy tubes – delivering ≤0.2 mm/m straightness without surface damage or work hardening. The Challenge of Straightening High‑Strength Alloy Tubes Tubes made from tough alloys – such as 17‑4 PH stainless, Ti‑6Al‑4V titanium, Inconel 718, and high‑strength carbon steels – resist permanent deformation. Their high yield strength and spring‑back make conventional straighteners ineffect

Twin‑line hydraulic drawbench independently processes aluminum rods, bars, and tubes simultaneously – maximizing productivity for EV battery cooling tubes, aerospace structural bars, and high‑volume aluminum profiles. Why Dual‑Line Drawing for Aluminum? Aluminum cold drawing demands smooth, vibration‑free force to preserve surface finish and achieve tight tolerances. When production volumes grow, adding a second separate drawbench doubles floor space, capital cost, and labor.

Fully automated hydraulic pointing technology delivers consistent, concentric tube and bar ends with smooth, programmable force – ideal for steel, stainless steel, aluminum, copper, and specialty alloys in high‑volume production. Why Upgrade to an Automatic Hydraulic Pointing Machine? Pointing is the critical first step in any cold drawing operation. A poorly formed point leads to carriage slippage, die damage, material waste, and production delays. Automatic hydraulic pointi
