NJZK Laser Technology Co., Ltd. was founded in 2013 with a registered capital of 80.33 million. It was founded by Dr. Xing Fei and his team as a "National Major Talent Project". It is a high-tech enterprise successfully incubated by Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences.
NJZK specializes in the R & D and manufacturing of laser additive manufacturing equipment (3D printing, laser surface technology), intelligent laser welding equipment, automated production lines, core devices (process software, powder feeders, processing heads) and 3D printed metal powder materials.
NJZK is a high-tech enterprise, a vice-chairman unit of the China Additive Manufacturing Industry Alliance, a standard drafting participant of the Additive Manufacturing Standards Committee, a laser remanufacturing industrialization project of the Development and Reform Commission, a laser additive manufacturing industrialization project of the Ministry of Industry and Information Technology, and a simultaneous delivery of the Ministry of Science and Technology. The major special unit for powder additive manufacturing is also the metal 3D printing engineering technology center of the Jiangsu Provincial Department of Science and Technology, the Jiangsu Enterprise Technology Center, and the Jiangsu Province Economic and Information Commission Laser Intelligent Manufacturing Collaborative Innovation Center. The company's high-power laser additive manufacturing equipment is a key new product.
The company has made breakthrough progress in large and medium-sized metal laser additive manufacturing equipment. Large powder-feeding metal 3D printing equipment uses core components with independent intellectual property rights (such as processing heads, powder feeders, process software, etc.). The results have been widely used in automobiles, ships, molds and other industries, providing end-users in the above fields with hundreds of sets of intelligent metal laser additive manufacturing equipment. NJZK has become a domestic supplier of serialized metal laser additive manufacturing equipment. Through continuous technological innovation and industrial integration, NJZK is closely focusing on the additive manufacturing industry chain and innovation chain, and vowed to be a high-quality brand in the domestic additive manufacturing field.
NJZK has developed and provided a number of remote laser welding systems, laser-MIG (MAG) composite welding systems, laser-TIG composite welding systems, narrow gap laser wire filler welding systems, laser brazing systems and so on. At the same time, the company conducted in-depth research on intelligent detection technology and closed-loop welding quality control technology in the process of laser welding. The related achievements won the first prize of the 2016 China Machinery Industry Science and Technology Progress and realized industrial application.
The company has made major breakthroughs in laser welding of high-temperature alloys, especially aluminum alloys, titanium alloys, and copper alloys. In the field of new energy vehicles, Zhongke Yuchen successfully conquered the laser welding problem of all-aluminum body and parts, and the motor copper alloy rotor laser Thanks to comprehensive strategic cooperation with Zhongwang Aluminum Group and KUKA Industrial Corporation, such problems as welding can provide customers with comprehensive system solutions for new energy vehicles from material innovative design, manufacturing process to integrated manufacturing equipment. In the marine field, NJZK has developed a welding method for key components with independent intellectual property rights, which successfully solves the technical problems of laser welding of thick plates. In the field of locomotive manufacturing, NJZK has achieved a breakthrough in the welding of key components in China's high-end manufacturing field. Customers in various industries provide laser welding high-end equipment solutions.
