Seiko New Energy: Technology Leader from Polycrystalline Silicon Equipment to Monocrystalline Silicon Equipment

Zhejiang Jinggong New Energy Equipment Co., Ltd. is a wholly-owned subsidiary of Zhejiang Jinggong Integrated Technology Co., Ltd. It is a national key high-tech enterprise and an excellent military civilian integration demonstration enterprise in Zhejiang Province. The company focuses on the development and technical services of high-tech products such as new energy equipment, aerospace specialized equipment, artificial intelligence automation production lines, and textile machinery specialized accessories. It is a pioneer in the domestic solar photovoltaic technology research and solar photovoltaic specialized equipment manufacturing industry, and a well-known customized specialized equipment production base in China.

Our mission is to assist the development of China's new energy equipment industry and focus on forward-looking exploration of new energy equipment. In 2008, the first JJL series polycrystalline silicon ingot furnace put into commercial production was born in Seiko Technology, successfully breaking industry technical barriers and filling domestic gaps.

With the accumulation of resources and technology, the company has fully shifted to the single crystal industry with higher market demand. It has successfully developed equipment such as JDL series single crystal furnaces, JXQ series slicers, JCL series deposition furnaces, and high-temperature purification furnaces, forming a mature technology research and development system and supply chain system. It has become one of the mainstream suppliers of single crystal silicon photovoltaic equipment, providing customers with superior one-stop solutions, Committed to becoming a mainstream supplier of global new energy equipment.

Product Introduction


▲ JDL series single crystal furnace

The JDL series single crystal furnace is a device that uses a graphite resistance heater to dissolve silicon materials in an inert gas (argon) environment and grows dislocation free single crystals using the Czochralski method (CZ). It can be used to manufacture high-quality single crystal rods required for solar cells.

This device has the advantages of stable performance, good automation, convenient production process, real-time remote or local monitoring, central centralized control, simple operation, and high crystallization rate.


▲ JXQ series diamond wire slicer

The JXQ series diamond wire slicer is a specialized precision equipment used for silicon wafer cutting in solar photovoltaic equipment. It is the equipment that accounts for the highest production cost and technical difficulty in the previous processes of solar cell production (crystal pulling, square cutting, and slicing).

This machine adopts the SIEMENS full servo control system and multi axis linkage control to achieve a stable and high-precision cutting method, cutting silicon wafers that meet the requirements of battery chip production.
