In recent years, Hai’an has accelerated its economic transformation and upgrading, vigorously developed new industries, and the photovoltaic photovoltaic industry has risen.

In the first half of the year, emerging industries realized sales of 5 billion yuan in invoices, an increase of 48% year-on-year, of which leading company Ebellec Energy realized invoice sales of 1.2 billion yuan, doubling year-on-year; Zhongli Keweida officially launched 40 solar cell and TFT production lines. It can achieve sales of nearly 300 million yuan.

The project under construction has progressed steadily. The county has more than 100 million yuan in photovoltaic photovoltaic projects with a total investment of over 10 billion yuan. Among them, Fengfeng Solar invested 3 billion yuan to build an annual output of 1000MW solar modules and 300MW BIPV photovoltaic products; Jiyang Henderson New Energy invested 3 billion yuan to build 1600MW ultra-thin crystalline silicon solar cells; Camdank invested 1.1 billion yuan in construction. With an annual output of 400MW solar cell silicon-based materials, Oudeli has invested RMB 1 billion to build TFT-LCD flat panel display optical films, solar power generation equipment, and solar backsheet films.

Reserve projects have potential. Currently, 12 projects with a total investment of 8 billion yuan have been filed, among which Nantong Shuguang New Energy has invested 700 million yuan to build wind power equipment and solar energy equipment projects; Nantong Unicom has invested 1.25 billion yuan to build an annual output of 600MW copper indium gallium selenide ( (CIGS) Software Coil Film Solar Photovoltaic Battery Project; Jiangsu Margo New Energy invested 600 million yuan to build monocrystalline, polycrystalline silicon solar cells and module production projects.

It is estimated that at the end of the “Twelfth Five-Year Plan”, Hai'an will build a new energy industry cluster centered on new energy industrial parks and photovoltaic photovoltaic industrial parks. There will be 20 million yuan enterprises in the cluster, of which 6 billion will be over 3 billion yuan. Invoicing sales of 25 billion yuan will help Hai'an economy develop soundly and quickly.

Precision Parts By Four-axis Machining

Precision parts are essential components of various machines and products that require high accuracy and reliability. The four-axis machining technology has ushered in a new era of precision manufacturing, where complex shapes and geometries can be achieved with greater efficiency and precision.


Four-axis machining involves the use of a computer numerical control (CNC) machine that has four axes of motion – X, Y, Z, and rotational axis. This advanced technology enables the machine to produce intricate and complicated parts with high precision and accuracy. Unlike the traditional three-axis machining, which can only move in three directions, the four-axis can rotate the part being machined, providing greater flexibility in terms of geometry and design.


Precision parts made using four-axis machining technology are widely used in various applications, including aerospace, medical equipment, automotive, and electronics industry. These parts are designed to meet stringent standards, making them reliable and durable. The four-axis machine can achieve tolerances as low as 0.001 inches, providing superior precision that is unmatched by manual machining.


One significant advantage of using four-axis machining technology is increased efficiency. The four-axis machine can perform multiple operations in a single cycle, reducing the time required to produce a part. This technology can also handle large volumes of parts with consistency, making it ideal for mass production.


In summary, precision parts made using four-axis machining technology offer a superior level of accuracy, reliability, and efficiency. These parts are widely used in various industries, and their high precision and accuracy make them a popular choice for critical applications. As manufacturing technology continues to evolve, we can expect more advanced techniques that will offer even greater efficiency and precision.
