FangRong delivers a fully automated three‑station cell to a leading manufacturer in Yangjiang – boosting output, reducing labor, and ensuring consistent quality for HVAC and plumbing components.
DONGGUAN, China – FangRong Precision Machinery has completed the design and shipment of a fully integrated pointing, drawing, and straightening line for a major metal processing factory in Yangjiang, Guangdong province. The system is engineered specifically for high‑volume production of copper and aluminum tubes used in air‑conditioning, refrigeration, and plumbing applications.
Why Yangjiang Manufacturers Are Investing in Integrated Lines
Yangjiang is a growing hub for metal fabrication, particularly in the HVAC and plumbing sectors. Local manufacturers face increasing pressure to:
Reduce labor costs – rising wages make manual handling expensive.
Improve surface quality – copper and aluminum are soft, prone to scratches during manual transfer.
Increase output – meeting growing domestic and export demand.
Ensure traceability – customers require full documentation of production parameters.
FangRong’s integrated line addresses all these challenges by linking pointing, drawing, and straightening into a single, automated flow – eliminating manual handling, reducing labor, and ensuring consistent quality.
The Integrated Line – Three Stations, One Flow
Station | Function | Key Technology |
1. Automatic Hydraulic Pointing Machine | Forms smooth, concentric points on tube ends – essential for die entry and carriage gripping | Four‑die hydraulic closure – ≤0.08 mm concentricity |
2. Precision Cold Drawing Machine | Reduces tube diameter and wall thickness – improves surface finish and dimensional accuracy | Closed‑loop force control – ±0.015 mm accuracy |
3. Multi‑Roll Straightening Machine | Corrects camber, bow, and twist – achieves ≤0.15 mm/m straightness | In‑line laser feedback – auto roll adjustment |
Material flow: Copper or aluminum tubes are loaded into a common magazine → pointed → transferred to drawbench → drawn → transferred to straightener → stacked – all without operator intervention.
Key Technical Specifications – Yangjiang Line
Station | Parameter | Range |
Pointer | Tube OD | 6 – 80 mm |
Wall thickness | 0.3 – 5 mm | |
Point concentricity | ≤0.08 mm | |
Drawbench | Drawing force | 20 tons |
Dimensional accuracy | ±0.015 mm | |
Drawing speed | 0 – 18 m/min | |
Surface finish | Ra ≤0.2 µm | |
Straightener | Straightness achieved | ≤0.12 mm/m |
Straightening speed | 10 – 50 m/min | |
Overall | Tube length (max) | 8 m |
Operator requirement | 1 (supervises the entire line) |
Materials Processed in the Yangjiang Line
Material | Typical Products | Why This Line Is Ideal |
Copper C12200 | HVAC coils, refrigerant lines, plumbing tubes | Surface‑protective handling – no scratches |
Aluminum 6061/6063 | Air‑conditioning tubes, heat exchanger components | Polyurethane rolls – no galling |
Copper C11000 | Electrical busbars, transformer components | Mirror‑bright finish – Ra ≤0.2 µm |
Benefits for the Yangjiang Factory
Benefit | Before (Separate Machines) | After (Integrated Line) |
Operators per shift | 3 | 1 |
Material handling steps | 6 | 0 (fully automated) |
Surface damage risk | High (manual handling) | Negligible (guided transfers) |
Straightness rejection | 3–5% | <0.5% |
Traceability | Fragmented logs | Single batch record |
Cycle time per tube | 2.5 min | 1.1 min |
Scrap reduction | 4–6% | <1% |
Why FangRong Was Chosen for This Project
26 years of experience – Proven technology in copper and aluminum tube processing.
Custom engineering – The line was designed to fit the factory’s existing floor layout and product mix.
Copper‑specific expertise – DLC‑coated dies, mandrel guidance, and polyurethane straightening rolls – eliminate galling and scratches.
Single‑source accountability – One supplier for all three machines – no interface disputes.
Local support – FangRong’s service team is based in Guangdong, ensuring rapid response.
Installation & Commissioning
The line was pre‑assembled and tested at FangRong’s Dongguan facility, then shipped in container‑friendly modules. Installation and commissioning are scheduled for Q3 2026, with on‑site training for the factory’s operators and maintenance team.
FangRong’s commitment: Full remote diagnostics support for the first 12 months, with spare parts stocked in the local warehouse.
Conclusion – A Future‑Ready Production Cell for Yangjiang
The pointing → drawing → straightening integrated line is more than just equipment – it is a production strategy. For the Yangjiang factory, it means:
Lower labor costs – one operator instead of three.
Higher quality – consistent ±0.015 mm accuracy and ≤0.15 mm/m straightness.
Faster throughput – 55% reduction in cycle time.
Full traceability – one log from raw tube to finished product.
