Ningbo Heli Technology Co., Ltd., a nationally recognized high-end precision mold and component manufacturer and leading champion in China’s manufacturing sector, continues to set industry benchmarks in die-casting and automotive lightweight solutions. As the first Chinese listed company focused on die-casting, foundry, and hot stamping molds, the enterprise integrates independent R&D, intelligent production and global supply services, forging comprehensive strengths in core mould development, aluminum alloy component manufacturing and commercial vehicle braking systems, while fully covering key product categories including Die Casting Die, Gravity Die Casting Mold, Hot Stamping Die, Low-Pressure Die Casting Mold, Patterns for Molding Line and Core Boxes.
Boasting total assets exceeding RMB 2 billion and annual operating revenue of RMB 1 billion, Heli Technology has built three core business divisions to form a diversified and complementary industrial layout, achieving deep layout in new energy vehicle lightweighting, automotive core components and commercial vehicle safety systems. The company’s mould business, as its core advantageous sector, stands as China’s largest production base for cast molds, with a full range of high-precision mould product lines that cover mainstream manufacturing processes in the automotive industry.
In the high-end mould sector, Heli Technology delivers comprehensive customized manufacturing solutions. Its flagship Die Casting Die products adapt to high-efficiency and high-precision production scenarios of complete vehicle parts, supporting ultra-large die-casting production with 9000T clamping force and super-heavy moulds weighing over 150 tons. Complementing its die-casting product matrix are professional Gravity Die Casting Mold and Low-Pressure Die Casting Mold, which are widely applied in the production of high-stability automotive structural parts and powertrain components, meeting the stringent precision and durability requirements of mainstream automobile manufacturers. Meanwhile, the self-developed Hot Stamping Die empowers the lightweight forming of high-strength automotive steel parts, effectively optimizing vehicle body structure and reducing overall body weight.
To guarantee the overall precision and matching accuracy of mould equipment, the company independently develops and manufactures supporting Patterns for Molding Line and professional Core Boxes. The standardized and serialized molding line patterns ensure consistent production precision and efficient line switching for mass production, while high-precision core boxes effectively improve the molding quality and yield of complex castings, laying a solid foundation for stable and high-quality batch production of downstream components. This complete upstream and downstream mould supporting system distinguishes Heli Technology from peer manufacturers and wins wide recognition from global clients.
Backed by strong production and R&D capabilities, the company’s mould division achieves an annual output of over 700 sets of various high-end moulds, with 25% of products exported to global markets. It has become a strategic supplier to international industry giants including NEMAK, MAGNA and KPSNC, and its mould products are widely used in supporting models of BMW, Mercedes-Benz, Volvo, BYD and other well-known automobile brands. In terms of R&D investment, Heli Technology has built a professional R&D team of more than 80 experts including professors and PhDs, carrying out in-depth industry-university cooperation with top universities such as Shanghai Jiao Tong University to tackle key lightweight manufacturing technologies. The company invests RMB 20 million in annual R&D funds and holds more than 30 authorized patents, continuously iterating and upgrading mould technology and product performance.
In terms of production guarantee, Heli Technology is equipped with 75 international advanced precision processing equipment including DMG MORI and GROB, and owns a 3,500-square-meter constant-temperature precision workshop. The digital PLM/MES management system realizes full-process intelligent control from mould design, processing to finished product inspection, ensuring micron-level precision of high-end mould products and supporting the stable delivery of high-quality moulds and components.
Leveraging its core mould technology advantages, the company’s Aluminum Alloy Components Division further extends the industrial chain, mastering multi-process precision casting technologies including high-pressure, low-pressure, gravity die-casting and 3D printing. It focuses on the R&D and production of new energy vehicle powertrain components such as motor housings and battery trays, as well as body structural parts including shock towers and subframes. The independently developed patented HL-111 heat-treatment-free aluminum alloy and high-thermal-conductivity HL-211 aluminum alloy fill the industry gap in lightweight material performance. The division is equipped with 25 high-pressure die-casting units from Bühler and Italpresse (ranging from 400T to 4400T), as well as advanced automated casting and machining production lines, realizing large-scale and high-precision production of aluminum alloy components.
The company’s Commercial Vehicle Braking Systems Division, honored as a National "Little Giant" Enterprise, focuses on the R&D and manufacturing of commercial vehicle braking systems and industrial parts. Its core products include automatic slack adjusters (ASA), air disc brakes (ADB) and air brake chambers, serving mainstream OEMs such as BYD, Yutong and King Long. In addition, the division has established in-depth strategic cooperation with Japan’s Nabtesco, jointly developing new energy functional parts represented by electric air compressors (EAC), and participating in the R&D and application of the world’s first heavy-duty commercial vehicle L5-level autonomous driving steer-by-wire (SBW) system, leading the technological upgrade of the commercial vehicle intelligent braking industry.
At present, Heli Technology has built mature manufacturing and R&D centers in Xiangshan (Ningbo) and Nanjing, with a radiating global customer system. The company has passed IATF 16949, ISO 14001, ISO 45001 international system certifications and owns CNAS-certified laboratories, achieving standardized and standardized management in product quality, environmental protection and occupational safety.
Looking ahead, adhering to the development vision of leading the industry in mega casting, lightweighting and sustainable development, Ningbo Heli Technology will continue to deepen technological innovation in high-end moulds and lightweight components, empower the iterative upgrading of the global automobile manufacturing industry with high-quality products and professional solutions, and strive to become a long-term trusted core partner in the new energy and lightweight manufacturing fields.
