Focused on Intelligent Welding & Cutting
Ningbo Baihua CNC Machine Co., Ltd. originated from Sinopec Ningbo Zhenhai Refining & Chemical, one of the top ten refineries in the Asia-Pacific region, and was founded by a technical expert team from a former petrochemical pipe prefabrication plant. As a major supplier to large state-owned and central enterprises, the company holds an AAA credit rating and stands out as a high-tech enterprise with both innovation strength and market credibility.
To meet growing global demand, we established an intelligent manufacturing base in Nantong, Jiangsu. Through joint R&D mechanisms with multiple universities at home and abroad, the company invests more than 40% of profits into annual R&D, continuously advancing technical innovation and product iteration to ensure every product delivers strong technical depth and outstanding quality.
Baihua stays aligned with the forefront of Industry 4.0 and intelligent manufacturing, providing end-to-end managed services spanning planning and design, software and hardware equipment supply, and industrial cloud platform deployment. This enables seamless integration between equipment digital data and ERP/MES systems, truly achieving digital welding, intelligent control, and information-based management.
We uphold the philosophy of “high standards, precision, and zero defects.” Our products remain stable after testing in demanding environments such as high heat, low temperatures, and high humidity, with an average design life of more than 15 years, earning strong market recognition through durability, stability, and safety.
“Integrity, respect, wisdom, professionalism, and focus” guide the Baihua team. Our products have been featured by CCTV-2 Finance Channel and CCTV-13 News Channel, helping drive the upgrade of intelligent manufacturing.
