Zhangjiagang Heshun Machinery Manufacturing Co., Ltd. is making strides in the high-end manufacturing sector. In January 2025, the company participated in the bidding for AVIC Xi'an Aircraft Industry Group's CNC pipe bending machine procurement project. Competing against industry players like Zhejiang Jinmarun and Jiangsu Hetai, Heshun secured third place in the comprehensive evaluation, becoming one of the shortlisted candidates.
Although it did not win the final contract, entering the candidate list for an aviation industry supply chain partner marks significant recognition for this enterprise, which has specialized in metal tube forming equipment for two decades.
01 Technical Strength: Patents Building Competitive Barriers
Innovation never stops at Heshun Machinery’s R&D center. In early 2024, its newly developed "A Lift Structure for Pipe Bending Machine Heads" was granted a national utility model patent.
This innovation features a unique main lead screw and reversible screw design, enabling precise and rapid vertical adjustment of the bending machine head. It addresses the industry pain point of inefficient equipment setup in tube processing.
Patent strategy is central to Heshun’s approach. Its technical team holds multiple independent intellectual properties in automotive manufacturing equipment, including patents for the "Dedicated Forming Machine for Automotive Seat Angle Adjustment Components" and its associated forming method.
These technologies replace traditional welding processes. Using a unique convex ring forming system, connecting plates are fixed to linkage pipes in a rivet-like manner, eliminating heat deformation issues caused by welding. This significantly improves the production quality and efficiency of automotive seat adjustment components.
02 Market Expansion: From Auto Parts to Aerospace
Inside Heshun Machinery’s production workshop, workers are calibrating a batch of CNC pipe bending machines ready for delivery. The company’s product line now covers the entire metal tube processing workflow, including metal circular saws, tube end forming machines, dual-head pipe benders, and nearly 60 types of equipment across ten major categories.
"Our equipment applications continue to broaden," stated the Sales Director. From initial use in bicycle and motorcycle manufacturing, Heshun’s products now serve diverse fields including auto parts, HVAC tubing, and aerospace, continuously pushing industrial boundaries.
Participation in AVIC XAC’s CNC pipe bender tender in early 2025 was a pivotal step into aviation manufacturing. The project required winning bidders to deliver equipment within six months of contract signing and complete installation and commissioning within three months.
These stringent delivery terms reflect the high standards of aviation manufacturing and demonstrate market confidence in Heshun’s technical capabilities. Although ranked third with a bid of ¥3.342 million, competing in such high-end projects signals that the company’s technological prowess has reached industry-leading levels.
03 Talent Engine: Core Driver of Technological Innovation
On Heshun Machinery’s recruitment board, openings for "Mechanical Engineers" and "Sales Managers" stand out. The company is actively expanding its team to build talent reserves for future growth.
"We seek multidisciplinary talent with both technical expertise and market understanding," emphasized the HR Director. Requirements for mechanical engineers include over two years of design experience, proficiency in relevant software, and familiarity with machining processes.
Sales team development similarly emphasizes professionalism. Sales manager positions offer monthly salaries exceeding ¥10,000, requiring candidates not only to develop clients but also to deeply understand product technologies and provide expert solutions.
This "Technology + Market" dual-driver talent strategy underpins the company’s sustained innovation. Led by technical pioneers like Han Hesheng and Chen Yi, the R&D team continues to break new ground in tube forming technology.
04 Sustainable Development: Balancing Eco-Friendliness and Innovation
In October 2021, the company received environmental impact assessment (EIA) approval from Suzhou Ecology and Environment Bureau for its "Machinery Equipment Manufacturing and Processing Relocation Project". Valid until 2099, this approval laid the foundation for long-term development.
The relocation was more than a site change—it represented a comprehensive production system upgrade. By adopting advanced technologies and management methods from Europe, America, and Taiwan region, Heshun continuously improves the sustainability of its production processes.
At its five-star office facility in Tangqiao Town’s High-Tech Industrial Park, Heshun embodies the ethos of a modern manufacturer. The company provides employees with comprehensive benefits including social insurance, training, and health checks, fostering a peopl
