Wencan Group Co.,Ltd.: history, ownership, mission, how it works & makes money

From a Guangdong die-casting startup founded in 1998 to a global auto-parts contender, Wencan Group Co., Ltd. (603348.SS) has grown through strategic moves like the 2020 acquisition of France's Bailian Group - adding a network of 12 production bases across Mexico, China, France, Hungary and Serbia - and a 2021 rebrand reflecting its broader scope; today the company lists on the Shanghai Stock Exchange with a market capitalization near 6.31 billion CNY (as of December 11, 2025), employs 6,425 staff (Dec 31, 2024) and reported 6.25 billion CNY in revenue for 2024, up 22.46% year-on-year, while navigating 2025 headwinds including a September fire at a Tianjin subsidiary and a first-half 2025 performance of 2.8 billion CNY revenue (down 8.88% YoY) with net profit attributable to shareholders of 13 million CNY (down 83.98% YoY); vertically integrated across R&D, high-tonnage die-casting and global manufacturing, Wencan monetizes advanced aluminum alloy precision castings for integrated body systems, battery housings and new-energy power systems, leveraging its Bailian capabilities and planned European capacity expansions to pursue higher-end customers and new-energy vehicle orders.

Wencan Group Co.,Ltd. (603348.SS): Intro

• Founded in 1998 as Guangdong Wencan Die Casting Co., Ltd., focused on automotive aluminum alloy precision castings.
• Rebranded in July 2021 to Wencan Group Co.,Ltd. to reflect broader scope and global operations.
• Acquired French Bailian Group in 2020, adding advanced die-casting technology and international footprint.
• Bailian acquisition brought 12 production bases across Mexico, China, France, Hungary, Serbia and other locations.
• September 2025: fire at wholly-owned Tianjin Xiongbang Diecasting Co., Ltd. (three-dimensional warehouse) - extinguished with no injuries; expected financial impact on 2025 results.
• 2025: secured new client project - supplier for a three-in-one Electric Machine casing with mass production slated for H2 2025.

• Design & engineering: alloy selection, casting design, die development and CAE simulation for high-pressure aluminum die cast parts.
• Manufacturing: high-pressure die casting, machining, heat treatment, surface finishing, assembly and testing across global plants.
• Value-added services: tooling/die manufacturing, R&D collaborations with OEMs, integrated components for EV powertrains (e.g., housings, casings, structural castings).
• Aftermarket & replacement parts: lower-margin but steady recurring revenue streams for non-OEM channels.

• Volume mix: automotive OEM programs (large-ticket, long-term contracts) vs. smaller industrial/aftermarket orders - OEM program wins drive revenue visibility and utilization.
• Product mix shift: higher content per vehicle for NEV powertrains (motor housings, e-motor casings, battery-related castings) increases ASP per part vs. traditional components.
• Vertical integration: in-house tooling, secondary machining and surface treatments capture additional margin compared to pure-foundry peers.
• Geographic diversification: factories in Mexico and Europe reduce currency/market concentration risk and improve proximity to global OEMs.

• Listed as 603348.SS on the Shanghai Stock Exchange (A-share listing).
• Revenue model: product sales (castings, machined components, assemblies), tooling and engineering service fees.
• Capital intensity: moderate to high - investment required for die sets, casting machines, machining centers and quality/test equipment; overseas M&A (Bailian) increased balance-sheet asset base.
• Risk factors affecting results: plant incidents (e.g., 2025 fire), raw material/aluminum price volatility, auto OEM demand cycles, FX exposure from overseas operations.

• Bailian acquisition (2020): immediate technology transfer, access to European OEM projects and manufacturing footprint across multiple countries.
• Product portfolio expansion into NEV powertrain components - higher content per vehicle and strong secular tailwinds from EV adoption.
• Continued pursuit of OEM program wins (e.g., three-in-one Electric Machine casing for mass production H2 2025) to improve plant utilization and margins.
