about us

MAC™ is located in Jinan, Shandong Province, China, which is known as the “City of Springs”. The company has a plant area of ​​more than 20,000 square meters and owns more than 50 machining equipment including CNC machining centers, CNC lathes, CNC milling machines, etc., which are used to manufacture CNC busbar bending machine, CNC busbar punching and shearing machine, 3 in 1 busbar machine and other products. It is a technical manufacturer specializing in the research and development and production of busbar processing machine.

Founded in 2005, Shandong Lijian CNC Machinery Co., Ltd. launched its brand LIJIAN™ and quickly captured 85% of the Chinese market share with its flagship busbar processing machine, the “3-in-1 Busbar Machine,” known for its high quality and cost-effectiveness, becoming a well-known busbar processing machine manufacturer in China.

Affected by the COVID-19 pandemic and with the support of the Jinan municipal government, we began to expand into overseas markets in 2021, registering Jinan Siwei E-commerce Co., Ltd. to handle overseas market development and sales. Simultaneously, We launched an overseas version of the brand: MAC™ and SUNSHINE™.

MAC™ is a new name card for the overseas version of LIJIAN™, representing a new identity for CNC busbar machines and intelligent busbar production lines, providing CNC automated busbar processing solutions for medium and large-sized switchgear manufacturers and large panel manufacturers. Products include CNC busbar punching and shearing machines, CNC busbar bending machines, CNC busbar chamfering machines, and automatic loading and unloading systems.

SUNSHINE™ focuses on providing economical and efficient busbar processing solutions for small and medium-sized switchgear manufacturers and micro-busbar processing plants. The product range includes semi-automatic multi-functional busbar processing machines, 3-in-1 busbar machines, and portable busbar machines.

Our factory has more than 85 employees, including 9 senior technical engineers, involving mechanical drawing, industrial control automation, processing and manufacturing and other related majors. We have obtained many patent certificates and technical product certificates for many consecutive years, and won the “Professional, Precision, Characteristic, and Innovative” enterprise award in Shandong Province, China.

Whether you are a high and low voltage switchgear manufacturer, a transformer factory, or a busbar supplier, you can find a busbar machine suitable for your project at MAC™. We have a rich busbar machine product line. If you are a busbar manufacturer with sufficient space and pay more attention to busbar processing efficiency, please choose our fully automatic CNC series busbar machine. If you are a distribution equipment manufacturer and provide busbar processing for your equipment, please choose our 3 in 1 series busbar machine. If you need to process the busbar at the project site or in a place with limited space, please choose our portable series busbar machine.

The fully automatic CNC series is divided into CNC busbar punching and shearing machine and CNC busbar bending machine. High efficiency, high precision, automation and support for 2D & 3D drawing import are the biggest advantages of these two busbar processing machines. The CNC busbar punching and shearing machine uses Swiss ABB motors to power the hydraulic system, independently develops the CNC system, and has been recognized by China’s national patent. The hydraulic system of the CNC busbar bending machine is replaced by a servo motor, and the bending force is more stable and uniform. At the same time, it can be connected to the CNC busbar punching and shearing machine by LAN or WIFI to realize program sharing.

We are well aware that different customers have different demands and budgets for busbar processing. The 3 in 1 series is divided into an economical multifunctional busbar machine and a servo multifunctional busbar machine. As the name suggests, the 3 in 1 series is a busbar machine with bending, punching and cutting functions, and can operate independently and simultaneously. The economical 3 in 1 busbar machine only has the bending unit that supports the PLC system, and the bending angle and other parameters are input through the HIM mobile display. The servo 3 in 1 busbar machine has three units that support the PLC system and realize automatic positioning of busbar processing.
