As China's first listed company specializing in die-casting, foundry, and hot stamping molds, Ningbo Heli Technology Co., Ltd. is accelerating its transformation into a trusted partner in the field of new energy and lightweight solutions through outstanding technical capabilities and a global strategic layout. With total assets exceeding RMB 2 billion and annual revenue of RMB 1 billion, Heli operates through three core divisions—Mold, Aluminum Alloy Components, and Commercial Vehicle Braking Systems—to continuously drive the high-end transformation of the manufacturing industry.
Mold Division: Benchmark of China's Casting Mold Production Base
As China's largest production base for cast molds, the Mold Division specializes in manufacturing high-pressure die-casting dies (Die Casting Die), gravity die-casting molds (Gravity Die Casting Mold), low-pressure die-casting molds (Low-Pressure Die Casting Mold), and Hot Stamping Dies. The division is not only a strategic supplier to global giants such as NEMAK, MAGNA, and KPSNC but also provides molds widely used in vehicles from BMW, Mercedes-Benz, Volvo, and BYD.
In terms of core capabilities, Heli produces over 700 sets of molds annually, 25% of which are exported. It can produce large-scale molds matching 9,000T clamping force and mega dies weighing over 150 tons. The company has an R&D team of over 80 experts (including professors and Ph.D.s), collaborates with top universities such as Shanghai Jiao Tong University on lightweighting technologies, invests RMB 20 million in R&D annually, and holds more than 30 patents. Its precision machining workshop is equipped with 75 high-end machines (DMG MORI, GROB) and features a 3,500 m² constant-temperature workshop, utilizing a digitalized PLM/MES system for high-precision manufacturing. In addition, Heli provides Patterns for Molding Lines and Core Boxes for casting production lines, offering complete process solutions for foundries.
Aluminum Alloy Components Division: Multi-Process Precision Casting Empowering New Energy Vehicles
This division masters multi-process precision casting technologies including high-pressure, low-pressure, gravity die-casting, and 3D printing. It focuses on producing key structural components for new energy vehicles (NEVs)—such as motor housings, battery trays, shock towers, and subframes—as well as traditional powertrain parts. In material innovation, Heli has developed proprietary heat-treatment-free aluminum alloys, including the patented high-elongation alloy HL-111 and the high-thermal-conductivity HL-211, significantly enhancing component performance. The division operates 25 high-pressure die-casting units (400T to 4,400T from Bühler and Italpresse), along with advanced low-pressure and gravity casting lines and automated machining centers.
Braking Systems Division: National "Little Giant" Defining the Future of Commercial Vehicles
Recognized as a national "Little Giant" enterprise, this division focuses on manufacturing automatic slack adjusters, air disc brakes, and air brake chambers for commercial vehicles, supplying major OEMs such as BYD, Yutong, and King Long. Through a strategic partnership with Japan's Nabtesco, Heli jointly develops new energy functional components, including electric air compressors (EAC). Furthermore, the company is involved in the development of the world's first heavy-duty commercial vehicle steer-by-wire (SBW) system for L5 autonomous driving.
Global Footprint and Vision for Sustainable Development
Heli operates manufacturing and R&D centers in Xiangshan (Ningbo) and Nanjing, serving a global customer base. The company holds IATF 16949, ISO 14001, ISO 45001 certifications and CNAS-accredited laboratories. Heli remains committed to achieving industry leadership in Mega Casting, Lightweighting, and Sustainable Development, providing more efficient and greener manufacturing solutions for the global automotive industry.
