As China’s first listed company specializing in die-casting molds and a nationally recognized manufacturing industry champion, Ningbo Heli Technology Co., Ltd. is solidifying its position as a trusted partner in new energy and lightweight solutions through outstanding technical expertise and a global footprint. With total assets exceeding RMB 2 billion and annual revenue of RMB 1 billion, the company operates through three core divisions—Mold, Aluminum Alloy Components, and Commercial Vehicle Braking Systems—building an end-to-end capability from design to mass production.
Mold Division: China’s Largest Casting Mold Production Base, Defining High-End Manufacturing Standards
Heli’s Mold Division is China’s largest production base for cast molds, specializing in Die Casting Die, Gravity Die Casting Mold, Hot Stamping Die, and Low-Pressure Die Casting Mold. As a strategic supplier to global giants such as NEMAK, MAGNA, and KPSNC, Heli’s molds are used in vehicles from BMW, Mercedes-Benz, Volvo, and BYD.
The division produces over 700 mold sets annually, 25% of which are exported. Its capabilities include mega dies for clamping forces up to 9,000T and molds weighing over 150 tons. The R&D team comprises more than 80 experts, including professors and PhDs, collaborating with top universities like Shanghai Jiao Tong University on lightweight technologies. With an annual R&D investment of RMB 20 million and over 30 patents, Heli operates a 3,500 m² constant-temperature workshop equipped with 75 precision machines (DMG MORI, GROB) and a digitalized PLM/MES system.
In addition to core casting molds, Heli also excels in producing Patterns for Molding Line and Core Boxes, providing complete tooling solutions for foundry production lines to ensure efficiency and precision in sand casting processes.
Aluminum Alloy Components Division: Multi-Process Precision Casting Empowering NEV Lightweighting
This division masters multi-process precision casting (HPDC, LPDC, GDC, and 3D printing) to produce complex, high-performance aluminum components. Its products include NEV powertrain components (motor housings, battery trays), body structural parts (shock towers, subframes), and traditional powertrain parts. The division has developed proprietary heat-treatment-free aluminum alloys such as the patented HL-111 (high elongation) and HL-211 (high thermal conductivity). Facilities include 25 high-pressure die-casting units (400T to 4400T from Bühler and Italpresse), along with advanced low-pressure and gravity casting lines and automated machining centers.
Braking Systems Division: National "Little Giant" Leading Commercial Vehicle Autonomous Driving Technology
As a national "Little Giant" enterprise, this division focuses on automatic slack adjusters (ASA), air disc brakes (ADB), and air brake chambers for buses and trucks, supplying major OEMs like BYD, Yutong, and King Long. Through a strategic partnership with Japan's Nabtesco, Heli develops and manufactures new energy functional parts, including electric air compressors (EAC), and is involved in the world’s first heavy-duty commercial vehicle steer-by-wire (SBW) system for L5 autonomous driving.
Global Footprint & Future Vision
Heli operates manufacturing and R&D centers in Xiangshan (Ningbo) and Nanjing, serving a global customer base. It holds IATF 16949, ISO 14001, ISO 45001 certifications and CNAS-accredited laboratories. Looking ahead, Heli will continue to lead the industry in mega casting, lightweight materials, and sustainable development, offering global customers one-stop technical solutions ranging from Core Boxes to complete vehicle structural parts.
