The Rebar Thread Rolling Machine prepares reinforcement bars for threaded mechanical couplers by forming a controlled thread profile at the bar end. It is intended for repetitive rebar-processing operations where accurate and consistent thread formation is required.

The machine can be specified according to the required rebar diameter range, thread profile, thread length, motor configuration, production capacity, and power supply. Exact machine specifications should be entered according to the supplied model and manufacturer datasheet.

HS Code Details

This classification applies because a rebar thread rolling machine forms threads by cold rolling and pressing the metal, rather than by cutting or removing material. This is the defining characteristic of machines classified under HS heading 84.63.

• Core Function: The machine must work by plastic deformation (rolling), not by cutting or grinding away metal. If a machine cuts threads by removing material (e.g., a lathe or tapping machine), it would be classified under a different heading (typically 8458 or 8459).

• Parts & Accessories: Components and accessories specifically for these machines (such as thread rolling dies or rollers) are generally classified under HS heading 84.66, unless they are interchangeable hand tools (which fall under Chapter 82)

Applications

• Threaded rebar coupler preparation
• RCC construction
• High-rise buildings
• Bridges and flyovers
• Foundations and pile foundations
• Columns and shear walls
• Industrial structures
• Infrastructure projects
• Rebar fabrication workshops

1. Clamping: The operator secures the TMT rebar inside a centering heavy-duty clamp. 
2. Rib Peeling: The machine activates, and integrated blades peel off the raised structural ribs at the end of the rebar to create a perfectly smooth, round cylinder. 
3. Thread Rolling: Once the ribs are peeled to the desired length, the peeling blades automatically retract, and the thread rolling head advances. Three circular die rollers compress the steel to roll precise, high-strength parallel threads. 
4. Reset & Unload: The spindle automatically reverses and retracts to its initial position once the thread length limit switch is triggered, allowing the operator to safely remove the finished bar. 

• Processing Diameter: Standard configurations handle rebars ranging from 16 mm to 40 mm. 
• Power Requirement: Driven by powerful 3-phase electric motors (typically between 3 HP to 10 HP / 5.5 kW to 7.5 kW) operating at 415V / 50Hz.
• Thread Details: Capable of pressing 2.5 mm, 3 mm, or 4 mm thread pitches in parallel patterns. 
• Machine Weight: Heavy-duty chassis build weighing between 350 kg to 450 kg to provide max structural stability during heavy pressure loads.
