General Details

Description

GF-20 Ring Making Machine – Semi-Automatic Steel Bar Ring Forming Solution (4–20 mm Capacity)Precision Bending, High Efficiency, and Rugged Durability for Reinforcement Ring ProductionThe GF-20 Ring Making Machine is a semi-automatic steel bar bending machine designed to form consistent and accurate circular rings from steel rods with diameters ranging from 4 mm to 20 mm. Engineered for speed, precision, and reliability, this machine is widely used in the construction, fabrication, and rebar processing industries for producing reinforcement rings used in columns, beams, and other structural elements.With its compact design, powerful motor, and simple operation, the GF-20 offers the perfect balance between manual control and automation — making it a versatile and cost-effective solution for medium-volume production environments.Key Features:Versatile Bending Capacity (4–20 mm):The GF-20 is capable of bending mild steel, TMT bars, and other steel rods with diameters between 4 mm and 20 mm. It supports ring sizes as small as 100 mm and can produce larger rings by adjusting the bending pins.Semi-Automatic Operation:The machine includes basic automation for ring forming, with manual feeding and alignment. Operators control the start and stop cycles using a foot pedal or control switch, offering precision without the complexity of fully automated systems.Durable and Stable Design:Constructed from heavy-duty steel with a reinforced frame, the GF-20 is built for long-term operation in rugged work environments such as construction sites, rebar yards, and fabrication shops.Powerful Electric Motor:Equipped with a 1.5–2.2 kW motor (depending on model), the machine delivers consistent bending performance with low power consumption, enabling continuous operation over long shifts.Adjustable Ring Diameter:The bending mechanism can be adjusted to produce rings of different diameters quickly and easily, without the need for complicated tools or long downtime.High Productivity:Capable of producing up to 500 rings per hour (depending on ring size and bar diameter), the GF-20 significantly boosts fabrication speed while ensuring uniformity in shape and size.Applications:The GF-20 Semi-Automatic Ring Making Machine is ideal for:Construction rebar processingPrecast concrete element productionManufacturing of pile cage rings and stirrupsFabrication of circular ties for columns and beamsIndustrial steel loop and hook productionTechnical Specifications (Typical):Parameter SpecificationModel GF-20Automation Grade Semi-AutomaticBar Diameter Capacity 4 mm to 20 mm (MS, TMT)Ring Diameter Range 100 mm – 1000 mm (adjustable)Motor Power 1.5 – 2.2 kWVoltage 220V / 380V, 50Hz, Single or Three PhaseProduction Rate Up to 500 rings/hour (depending on size)Control Type Manual start/stop with foot pedal or switchPlatform Type Fixed base with adjustable forming pinsMachine Weight Approx. 350–450 kgDimensions (LxWxH) Approx. 900 x 800 x 950 mmAdvantages:Compact & portable design – fits easily in workshops or on-siteEasy to operate – minimal training requiredQuick diameter adjustments – versatile for multiple project needsLow maintenance – strong mechanical build with durable componentsConsistent output – ensures uniform ring sizes every timeAffordable automation – ideal for mid-scale operations seeking productivity gainsOptional Features:Digital counter for batch trackingCustom die sets for different bar profilesHeavy-duty trolley for mobile useSafety guard and emergency stop systemThe GF-20 Ring Making Machine combines simplicity, strength, and efficiency to meet the needs of modern construction and fabrication industries.
