The LG-60aggravate-H Cold Rolling Machine is engineered to transform metal “shells” (semi-finished tube blanks) into high-quality seamless tubes through a continuous, cyclic rolling process. Unlike traditional tube-forming equipment, it integrates advanced mechanical transmission and precision control technologies to ensure consistent output and reduced material waste.

Backed by Jiangsu Yongteli’s decades of expertise, the machine is built in a modern production facility spanning over 40,000 square meters—equipped with advanced processing and testing equipment—to meet strict industry standards. Its design focuses on user-friendliness, durability, and scalability, making it suitable for both small-batch customization and large-scale mass production.
The machine adopts a two-roller ring die structure (mounted on the movable frame M1) that works in tandem with a mandrel to shape seamless tubes. This design ensures uniform pressure distribution during rolling, minimizing deformation errors and enhancing the consistency of tube wall thickness (typical tolerance as low as ±0.02mm for standard materials).
Powered by a high-torque main motor, the LG-60aggravate-H uses a pulley deceleration mechanism to drive components M3 and M2, then connects to the frame via a brace connecting rod structure. This transmission chain reduces energy loss by up to 15% compared to conventional gear-driven systems, while enabling smooth linear reciprocating motion of the frame for continuous rolling cycles.
In each working cycle, the machine’s taper die adjusts from small to large when the head reaches limit position (Location A). The mandrel rotates the metal shell by a precise angle and feeds it forward, while the pass (formed by the two rollers and mandrel) changes size dynamically—shrinking during the forward stroke (rolling) and expanding during the reverse stroke (resetting). This automated process cuts manual intervention by 80% and shortens the production cycle for a single seamless tube by 25% on average.
The LG-60aggravate-H supports tube outer diameter ranges from 15mm to 60mm and wall thicknesses from 1.2mm to 8mm, accommodating diverse seamless tube specifications without frequent mold replacements. This flexibility makes it ideal for small-batch trial production and large-scale order fulfillment alike.
The LG-60aggravate-H Cold Rolling Machine is versatile enough to serve multiple industries, thanks to its ability to process various metals. Below are its core application areas:
Ideal for processing non-ferrous metals like copper, aluminum, and their alloys—materials widely used in HVAC systems, electrical conductors, and decorative pipes. The machine’s gentle rolling process preserves the mechanical properties of non-ferrous metals, avoiding cracking or brittleness. For example, it can produce aluminum seamless tubes for air conditioning condensers with a surface finish of Ra 0.8μm or better.
Suitable for 304, 316L, and other stainless steel grades, which are critical for food processing equipment, medical devices, and marine engineering. The machine’s precision control ensures stainless steel tubes meet hygiene standards (e.g., FDA compliance for food-contact applications) and corrosion resistance requirements.
Alloy steel pipes (e.g., chrome-molybdenum steel) are essential for high-pressure environments like oil and gas pipelines, power plant boilers, and hydraulic systems. The LG-60aggravate-H can process these high-strength materials with tight dimensional tolerances, ensuring the pipes withstand pressures up to 30MPa (depending on material and thickness).
For carbon steel pipes used in construction (e.g., structural supports), mechanical engineering (e.g., machine shafts), and automotive parts, the machine delivers efficient production with low material waste. It can process carbon steel shells into pipes with lengths up to 6 meters, meeting the demands of large-scale infrastructure projects.
The machine is designed to handle a wide range of metals, including non-ferrous metals (copper, aluminum, brass), stainless steel (304, 316L, 321), alloy steel (4130, 4340, chrome-molybdenum steel), and carbon steel (Q235, Q345). For special materials (e.g., titanium alloys), Jiangsu Yongteli offers customized modifications to the roller die and mandrel to ensure optimal processing results.
Production capacity varies based on tube specifications (diameter, thickness, length) and material type. For standard carbon steel tubes (outer diameter: 30mm, wall thickness: 3mm), the machine can achieve a capacity of up to 500 pieces per 8-hour shift. For thicker or harder materials (e.g., stainless steel 316L), capacity adjusts to approximately 350 pieces per shift—still 15-20% higher than comparable two-roller cold rolling machines on the market.
Yes. Jiangsu Yongteli offers comprehensive after-sales services, including: on-site installation and commissioning (within 7 working days of equipment delivery), operator training (2-3 days of hands-on sessions), and 24/7 technical support via phone (+86-13336683488) or email (jskaizhongJx@qq.com). The company also provides spare parts supply with a lead time of 3-5 days for common components (e.g., roller rings, mandrels).
Absolutely. The machine meets ISO 9001:2015 quality management standards and GB/T 30589-2014 (Chinese national standard for cold rolling mills). It also complies with safety standards such as CE (for European markets) and UL (for North American markets), ensuring seamless import and operation in global regions.
The standard lead time is 45-60 working days from the date of order confirmation. This includes manufacturing, quality testing, and packaging. For urgent orders (e.g., within 30 days), Jiangsu Yongteli can prioritize production with a 10% surcharge—subject to factory capacity availability.
