A leading national high-end precision mold and component manufacturer and industrial champion in China’s manufacturing sector, Ningbo Heli Technology Co., Ltd. continues to consolidate its market advantages in new energy vehicle (NEV) lightweighting and precision manufacturing. As China’s first listed company focused on die-casting, foundry, and hot stamping molds, the enterprise integrates independent R&D, intelligent production and full-scenario product solutions, covering core products such as Die Casting Die, Gravity Die Casting Mold, Hot Stamping Die, Low-Pressure Die Casting Mold, supporting customized production of Patterns for Molding Line and Core Boxes, and serving global mainstream automotive and commercial vehicle brands.
Boasting total assets exceeding RMB 2 billion and annual revenue of RMB 1 billion, Heli Technology has built three core business segments: Mold, Aluminum Alloy Components, and Commercial Vehicle Braking Systems, forming a complete industrial chain layout from high-precision mold development and lightweight component manufacturing to commercial vehicle core braking parts supply. Its production and R&D bases located in Ningbo Xiangshan and Nanjing lay a solid foundation for large-scale, high-precision and intelligent manufacturing.
The company’s Mold Division stands out as China’s largest production base for casting molds, specializing in the R&D and manufacturing of a full range of precision mold products. Its core product matrix includes high-performance Die Casting Die for high-pressure die-casting processes, durable Gravity Die Casting Mold tailored for gravity casting production, stable Low-Pressure Die Casting Mold adapted to low-pressure casting scenarios, and high-precision Hot Stamping Die for automotive body hot stamping forming. Meanwhile, the division supports the design and production of professional Patterns for Molding Line and customized Core Boxes, fully meeting the differentiated and high-precision production needs of automotive lightweight parts.
Backed by strong production and R&D capabilities, the Mold Division achieves an annual output of over 700 sets of various precision molds, with 25% of products exported overseas. It is capable of manufacturing super-large molds matching 9000T clamping force and ultra-heavy molds weighing more than 150 tons. The company has assembled a professional R&D team of over 80 experts including professors and PhDs, and carries out in-depth industry-university cooperation with top institutions such as Shanghai Jiao Tong University to iterate and upgrade lightweight manufacturing technologies. With annual R&D investment of RMB 20 million and more than 30 authorized patents, Heli Technology maintains continuous technological innovation momentum. Equipped with 75 high-end precision processing equipment from DMG MORI and GROB, as well as a 3,500-square-meter constant-temperature precision workshop, the company adopts digital PLM/MES management systems to realize full-process precise control of mold production, winning long-term strategic supplier qualifications from global industry giants including NEMAK, MAGNA and KPSNC. Its molds are widely applied in mass-produced vehicles of BMW, Mercedes-Benz, Volvo, BYD and other well-known brands.
Complementary to the mold business, the Aluminum Alloy Components Division relies on multi-process precision casting technologies including high-pressure, low-pressure, gravity die-casting and 3D printing to produce complex and high-performance aluminum lightweight parts. Focusing on NEV powertrain and body structural components, the division’s core products cover motor housings, battery trays, shock towers and subframes. It has independently developed proprietary heat-treatment-free aluminum alloy materials represented by patented HL-111 high-elongation alloy and HL-211 high-thermal-conductivity alloy, breaking through material performance bottlenecks in lightweight manufacturing. The production base is equipped with 25 advanced die-casting units ranging from 400T to 4400T imported from Bühler and Italpresse, as well as automated low-pressure, gravity casting lines and intelligent machining centers, ensuring high-efficiency and high-quality mass production of aluminum components.
The Commercial Vehicle Braking Systems Division, a recognized National "Little Giant" Enterprise of China, focuses on the R&D and production of commercial vehicle braking system parts and industrial components. Its main products include automatic slack adjusters (ASA), air disc brakes (ADB) and air brake chambers, which are supplied to mainstream OEMs such as BYD, Yutong and King Long. In terms of technological layout, the division has established in-depth strategic cooperation with Japan’s Nabtesco to jointly develop and manufacture new energy functional parts represented by electric air compressors (EAC). Furthermore, the two parties are deeply involved in the R&D and iteration of the world’s first heavy-duty commercial vehicle L5-level autonomous driving steer-by-wire (SBW) system, leading the technological upgrading of commercial vehicle intelligent driving.
In terms of quality management and system certification, Heli Technology has obtained authoritative certifications including IATF 16949, ISO 14001 and ISO 45001, and owns a CNAS-certified professional laboratory, realizing standardized and normalized quality control throughout R&D, production and testing. Looking ahead, the company will continue to focus on mega casting technology, automotive lightweighting and sustainable manufacturing, further empowering the high-quality development of the global new energy automobile industry with full-chain mold and component innovation capabilities.
