Our Strength

Dalian Kangzhan M & E Engineering Co.,Ltd has its own modern factory and office area 24300 ㎡, and has good R&D, design and production conditions. The company has R&D department, project engineering department, software engineering department, production and assembly department, marketing department and after-sales service department. Professional and technical personnel account for 52% of the company's total employees. At the same time, it has many years of knowledge accumulation and product manufacturing experience.

The electric intelligent tightening machine produced by the company has matured and has its own independent brand through technology introduction and secondary development. Due to its technical content, assembly accuracy and high cost performance, this type of product is widely used in the manufacturing and assembly fields of automobiles, engines, gearboxes, axles, etc.

The assembly lines, special machines, auxiliary machines and testing equipment produced by the company have covered the manufacturing fields of automobile parts such as engines, gearboxes, axles, etc. Among them, the engine assembly line, main reducer assembly line, wheel hub brake drum assembly line and brake assembly line have been widely used.

The company's newly developed axle ABS testing machine, axle toe measuring machine, axle steering angle measuring machine, axle running-in test and noise measuring machine, engine connecting rod processing trinity machine, etc., have filled the domestic gap in the field of automobile assembly testing. The axle ABS testing machine, toe measuring machine, steering angle measuring machine and running-in test and noise measuring machine that have been put into production have been in short supply. Currently, we are planning to put them into large-scale production, and has applied for special patents.

Our Company takes "user satisfaction and dedication of fine products" as its purpose, strives to provide customers with high-quality products and satisfactory services; with "self-improvement and pursuit of excellence" as its core, it actively promotes management innovation and technological innovation, continuously improves the company's comprehensive strength and core competitiveness, and creates a well-known company in the industry.

Konson Intelligent Tightening System

Konson brand tightening system is a high-tech assembly tightening tool with high efficiency, high precision and low noise, which is independently developed by Dalian Kangzhan and has its own intellectual property rights. It has the advantages of compact, durable and easy integration. The tool adopts the structure form of imported brands from abroad, avoiding the defect of low integration degree of domestic brands, and adopts Ethercat bus architecture, making the system topology flexible, simple and easy to use, fast response, good synchronization and strong real-time performance.

Konson tightening system is divided into two types according to the performance of the tightening spindle : standard type and high-performance type . Both tightening spindle systems are composed of a power supply module (PSM), a master station module (MSM), a slave station module (SSM), and a tightening spindle.
