Bar threading machine YG series

Product Overview
A reliable hydraulic thread rolling machine designed for fast, precise rebar threading. The machine forms clean, full-profile threads by cold forming, improving connection strength while reducing processing time. Durable rollers and a stable hydraulic system enable consistent results and long service life.

Key Features

• Hydraulic-driven rolling for stable and consistent thread formation
• High-precision rollers producing full-profile threads
• Cold forming (no cutting) so thread strength exceeds base rebar
• Supports forward and reverse threading
• Operable by one operator with minimal training
• Processes rebar diameters 16–40 mm and performs peeling and threading in one setup
• Improves tensile, fatigue, and corrosion resistance of joints
• Higher processing throughput and lower labor demand compared with manual methods

FAQ (selected)

• Q: How long does it take to process one rebar? A: Most joints take about one minute depending on diameter and thread length.
• Q: Can it work with other equipment? A: Yes. It is commonly paired with rebar straightening machines, hydraulic rebar benders, or rebar upsetting machines for integrated processing lines.
• Q: What is the difference between a hydraulic and an automatic model? A: The hydraulic model emphasizes power and stability; the automatic model offers faster feeding and reduced manual handling.
• Q: How to select the right thread rolling machine? A: Confirm rebar type, diameter range, desired thread length, duty cycle, and hydraulic pressure. For large-volume processing choose higher power and durable rollers.
• Q: How to reduce threading errors? A: Errors often originate from worn rollers or incorrect adjustments. Calibrate the peeling blade before rolling and match roller pitch with the coupler; monitor roller wear.
