Our Operations
Our operations are based in Wuxi China. The operations include two business segments:

Forged rolled rings and related products

  • Products for the wind power industry

Using precision forging technology we deliver high quality, large forged rolled rings, yaw bearings and shafts for use in large-scale windmills. We believe the combination of our advanced technological expertise, a state-of-the-art production facility, and a well-established long-term customer network sets us apart from our competitors. As a key industry player, we are well-positioned to become a leading global wind components supplier in the years to come.

  • Products for other industries

In addition to serving the needs of the wind industry, we also manufacture and supply various types of heavy duty precision forgings, fabricated components, and assemblies to other clean technology industries.

Our operations feature a 4,500-ton press and a ring-rolling mill, employing our advanced axial close-die forging technology, to 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. We also have a series of workshops dedicated for fabrication, welding, machining and assembly of high strength materials. We are ISO9001:2000 certified supplier and have strong international management, engineering and technical capabilities, ensuring our ability to meet the requirements of the most demanding global customers.

Dyeing and Finishing Equipment

  • Products for the dyeing and finishing operations of the textile industry. 

We design, manufacture and distribute a line of proprietary high and low temperature dyeing and finishing machinery. We believe that we are one of the leading domestic Chinese manufacturers of textile dyeing machines, and our Huayang brand is nationally recognized.

We have won local manufacturing awards for this business and we hold six Chinese patents that cover an innovative production technique enabling more-effective cloth washing in dyeing machines under high temperature and pressure, the dyeing liquid mixing device, dyeing liquid atomizing device, horizontal manipulated devices, mechanical seal and atomizer of the airflow dyeing machine. 

We currently have the capacity to manufacture and assemble approximately 550 textile-dyeing machines annually. Our state-of-the-art and automated production line enables us to manufacture our products efficiently, with lower labor and energy costs compared to traditional manufacturing methods. As part of our manufacturing process, we make corrosion-resistant stainless steel pumps and pressure vessels, which are not only critical components for our dyeing and finishing products but have other industrial applications as well.

Our dyeing and finishing products are generally compact in design compared with alternatives on the market and feature a high degree of both automation and mechanical-electrical integration. Our products are used in dyeing yarns such as pure cotton, cotton-polyester, terylene, polyester wool, poly-acrylic fiber, nylon, cotton ramie, and wool yarn. In 2010, we introduced an advanced dyeing technology enabling a quick, economic and environment-friendly operation designed for optimal performance. The liquid pressure and quantity are adjusted to the respective type and quantity of fabric. The special layout of the pressure pump circuit is designed to provide constant and safe operations of the machine reducing resources wastage and enhancing performance.

Our latest product innovations include a new model of dyeing machine – high (low) temperature airflow dyeing machine to meet the latest industrial environmental standards and a new after-treatment drying and compacting machine which 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 are currently developing a new garment washing machine for denim, capable of stone wash, enzyme wash and other water washing techniques.

Our Facilities
Our operations feature a 4,500-ton press and a ring-rolling mill, employing our advanced axial close-die forging technology, to 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. We also have a series of workshops dedicated for fabrication, welding, machining and assembly of high strength materials. We are ISO9001:2000 certified supplier and have strong international management, engineering and technical capabilities, ensuring our ability to meet the requirements of the most demanding global customers.

The melting, forging, heat-treating and machining capability at our facility 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. We believe that we are capable of producing components that meet various industry specifications as well as product-specific specifications.

Our manufacturing site covers over 1.1 million square feet. In addition to our forging operation we have established state-of-the-art fabrication, machining, assembly and finishing workshops to meet the manufacturing needs of our clean technology focused customer base.
