Many of these customers supply clean technology equipment such as wind turbines or require increasingly energy efficient equipment for their own manufacturing processes such as dyeing and finishing machines. The Company’s success has been built upon:

World Class Provider of Precision Forged and Fabricated Solutions

Leading-Edge Technology
For our dyeing and finishing equipment customers in the textile industry, we design, manufacture and distribute a line of proprietary high and low temperature dyeing and finishing machinery. Our products feature a high degree of both automation and mechanical-electrical integration. Our products are widely used in dyeing yarns such as pure cotton, cotton-polyester, terylene, polyester wool, poly-acrylic fiber, nylon, cotton ramie, and wool yarn. Our latest airflow dyeing units use air instead of water, enabling our customers to meet stricter environmental standards, reduce their input costs, and produce textiles with fewer wrinkles and less fabric damage.

For our wind power and customers in other industries, we manufacture and supply rolled rings and other related components. We use the latest axial close-die forging technology to manufacture rotary precision forgings, using forging equipment which we manufactured for our own use. The axial close-die forging technology reduces the use of raw materials by as much as 35%, provides a high precision and surface flatness, reduces the cutting output, has excellent mechanical strength and high flexibility, and is a fully automatic operation.

High-Quality and Outstanding Performance
We believe top-quality is a must.

Our Products

World Class Provider of Precision Forged and Fabricated Solutions
We manufacture rolled rings and other related components designed to be used in the wind power industry as well as for other uses.

Die Forging for Greater Strength and Flexibility

We employ axial close-die forging technology in producing precision forgings, a technology for producing rotary precision forgings. We made the forging machine ourselves, providing a strong advantage in machine maintenance and cost compared to other companies using foreign equipment.

Our rolled rings are essentially hollow cylindrical sections forged from a stainless steel stock of varying thickness and height. The rings are called rolled rings because of the nature of the forging process. Forging is a manufacturing process where metal is pressed, pounded or squeezed under great pressure to create high strength parts. Rolled ring forging turns a hollow round piece of metal under extreme pressure against a rotating roller, thereby squeezing out a single-piece ring without any welding required.

Although rings can also be manufactured through machining or casting, we believe that forging produces a finished product with greater strength and flexibility. A ring’s strength affects its fatigue resistance, and is determined by the orientation of the grain flow of the ring’s metal material. Unlike the machining process, which creates a unidirectional grain flow, or the casting process, which creates no grain flow, the forging process is designed to cause alignment and orientation of the grain flow in a direction creating maximum strength, thereby providing maximum fatigue resistance. This high strength property also reduces sectional thickness and overall weight of the ring without compromising the overall integrity of the finished product.

The Many Uses of Rolled Forged Rings
High tangential strength and ductility make forged rings well-suited for torque- and pressure-resistant components, such as gears, engine bearings for aircraft, wheel bearings, couplings, rotor spacers, sealed discs and cases, flanges, pressure vessels and valve bodies. As such, rolled rings have a wide variety of applications. Presently, the majority of Chinese rolled ring producers rely on technologies such as the steam hammer and friction press, which consume large amounts of energy and cause pollution, and which, we believe, generate a less desirable product.

Yaw bearings, which are found in every wind turbine, are made from rolled rings. Essentially, a yaw bearing is a large ring with teeth, all of which are either pointing outward or inward. The teeth allow the yaw bearing to engage with a smaller wheel attached to the yaw motor. The yaw motor turns the wind turbine so that the rotor (to which blades are attached) faces the wind in order to optimize electricity generation. The yaw bearing is used by the yaw motor to turn the wind turbine.

Dyeing and Finishing Equipment Segment
We design, manufacture and distribute a line of proprietary high and low temperature dyeing and finishing machinery to the textile industry. Our products feature a high degree of both automation and mechanical-electrical integration. Our products are widely used in dyeing yarns such as pure cotton, cotton-polyester, terylene, polyester wool, poly-acrylic fiber, nylon, cotton ramie, and wool yarn.

Environmentally Friendly Airflow Dyeing Machines
We now design and produce airflow dyeing machines, which use air instead of water. Water is used in the traditional dyeing process. We believe that our air-flow technology, which is designed to enable users to meet the stricter environmental standards, results in reduced input costs, fewer wrinkles, less damage to the textile, and reduced emissions. With the growing acceptance of our new dyeing technology and the China government’s mandate to phase out older machinery in China’s textile industry that does not meet the new environmental standards, we expect further success in the future.

After Treatment Compacting Machines
Our new after-treatment drying and compacting machine is used in the final finishing of knitted material, such as cotton, and is designed to improve the softness, reduce shrinkage and ensure better dimensional stability. We believe that our equipment offers performance similar to German and US imports at a more attractive price.

Garment Washing Machines for Denim
We are currently developing a new garment washing machine for denim. Made of stainless steel and customized for use by Chinese jeans manufacturers, the machine is capable of stone wash, enzyme wash and other water washing techniques. We believe that our machine will offer superior quality and performance at an attractive price relative to machines imported from Germany and the US, and expect it to be well received by potential customers.

Our manufacturing site covers over 1.1 million square feet. We have established state-of-the-art fabrication, machining, assembly and finishing workshops and a state-of-the-art forging facility with a 4,500-ton press and a ring-rolling mill that employs our advanced axial close-die forging technology. This facility has an annual capacity of 50,000 tons.

We are leading specialists in the manufacturing of:

  • · Proprietary high and low temperature dyeing and finishing machinery to the textile industry
    · Large forged rolled rings, yaw bearings, tower flanges and shafts used in large-scale windmills
    · Stainless steel pressure vessel/chambers used in the manufacturing of multi-crystalline solar  wafers
    · Specialty, high tolerance, fabricated components and assemblies used in various clean technology  industries
    · Other fabricated and machined components, assemblies and equipment requiring high precision  manufacturing
Due to our extensive manufacturing capabilities that are especially well-suited for components required in wind turbine manufacture, we believe that we are a major Chinese manufacturer of important components for that industry including:
  • · Large forged rolled rings
    · Yaw bearings
    · Tower flanges and
    · Shafts used in large-scale windmills

At this facility we can manufacture rolled rings measuring up to 6.3 meters in diameter and a cross section up to 700mm and shafts used in wind turbine units, measuring 1MW-3MW.

The melting, forging, heat-treating and machining capability at Cleantech Solutions International allows for the manufacturing of a wide range of custom-forged products. Multi-diameter shafts, gear blanks, mandrel-forged rings and specialized shapes, are available in a wide range of sizes and weights ranging from a few hundred pounds to over 25,000 pounds. Most popular carbon and alloy AISI/SAE grades such as 1026, 1045, 4140, 4150F, 4340, and 8620 are readily available. We also have experience with the melting and forming of specialized alloys. Cleantech Solutions International is capable of producing components that meet various industry specifications such as ASTM, ASME, ABS and AMS, as well as product-specific specifications.
