Five Chinese BMC and SMC composite parts makers to watch in 2026

China’s BMC and SMC composite parts supply chain is gaining attention as demand rises in automotive, electrical and rail applications. A new industry profile spotlights Zhejiang Aobang Technology and four other manufacturers positioned to serve buyers seeking molded composite components and related materials.

Why it matters: - The global SMC and BMC market was valued at USD 35.77 billion in 2024 and is projected to reach USD 67.98 billion by 2035, according to Market Research Future. - Asia Pacific held a 63.0% revenue share of the global SMC and BMC market in 2025, according to Grand View Research. - China dominates the regional market because of its composites manufacturing clusters and electric vehicle production capacity. - Buyers in automotive, electrical, rail and industrial markets are looking for suppliers that can deliver flame-retardant, corrosion-resistant and lightweight composite parts.

What happened: - An industry profile identified five Chinese manufacturers active in the BMC and SMC ecosystem, led by Zhejiang Aobang Technology Co., Ltd. - The other companies named were Ningbo Huayuan New Materials Co., Ltd., Jiangsu Zhaoyun New Materials Co., Ltd., Shengming (Shandong) New Material Technology Co., Ltd. and Zhejiang Sansheng Mould & Plastic Technology Co., Ltd. - The profile framed the companies as part of China’s broader composite supply chain rather than as identical direct substitutes. - Zhejiang Aobang Technology, founded in 2010, is based in Deqing County, Huzhou City, Zhejiang Province.

The details: - BMC, or bulk molding compound, is supplied in bulk form, while SMC, or sheet molding compound, is supplied as a sheet. - Both materials are glass-fiber reinforced thermoset composites processed mainly by compression molding. - Common performance traits include high mechanical strength, dimensional stability, flame retardancy and corrosion resistance. - Polyester-based BMC held a 65% market share in 2024 and was valued at about USD 1.37 billion, according to Market Research Intel. - Glass fiber reinforcement accounted for 62.1% of the total fiber segment in the SMC and BMC industry in 2025, according to Grand View Research. - Typical applications include BMC motor encapsulation, SMC EV battery housings, SMC electrical enclosures, insulating components, auto parts and railway transportation components. - Zhejiang Aobang operates a 20,000-square-meter factory and employs 150 people. - Zhejiang Aobang’s main product is the ARF Antibacterial Board, a GFK composite panel made of polyester resin, glass fiber and filler. - The panel comes in sizes from 300×300 mm to 600×1500 mm. - The product is available in high gloss, coarse texture, wood grain, brushed texture, special-shape and sound-absorbing variants. - The panel uses high-temperature de-moulding and one-piece on-line lamination to create a scratch-resistant, washable and dimensionally stable surface. - The panel composition includes glass fiber, flame-retardant resin, aluminium hydroxide and silver-containing antibacterial agents. - Zhejiang Aobang says the panel has a Class A2 fire-resistance rating, an antibacterial rate above 99.9%, Class 1 mildew resistance, acid-alkali and oxidization resistance, and a 25-year service life. - Zhejiang Aobang says the panel provides thermal and sound insulation and can reduce power consumption by 15% because of its thermal insulation performance. - The company introduced industrial GFK product technology from Germany in 2010 and later developed proprietary GFK technologies through independent R&D. - Zhejiang Aobang holds ISO environmental management system certification and ISO quality management system certification. - Zhejiang Aobang is recognized as a National High-Tech Enterprise and holds multiple national invention patents and utility model patents. - The company’s main markets are the EU and China, with uses in hospitals, schools, banks, high-speed-rail stations and other public venues. - The company’s official website is More information. - Ningbo Huayuan New Materials is based in Ningbo, a port city with dense composite materials and automotive parts supply chains. - Jiangsu Zhaoyun New Materials operates in Jiangsu, a manufacturing hub for automotive, electronics and composite materials. - Shengming (Shandong) New Material Technology is based in Shandong, where construction materials and transportation equipment industries are concentrated. - Zhejiang Sansheng Mould & Plastic Technology combines mold design and plastic technology, which matters because BMC and SMC parts are produced through compression molding. - Zhejiang Sansheng’s integrated tooling and mold-making capabilities make it relevant for custom BMC and SMC parts and low-shrinkage molded components. - Automotive applications represented the largest end-user segment for BMC in 2024, accounting for 38% of the market, or USD 0.80 billion, according to Industry Insights. - Transportation is expected to remain the dominant end-user through the 2024-2030 forecast period, according to Strategic Assessment Group. - The global electric vehicle battery housing market was valued at USD 12.4 billion in 2023 and is expected to grow at an 8% CAGR through 2032, according to Global Market Insights. - SMC composite battery covers reached USD 1.38 billion in market size in 2024, driven by EV adoption, according to a Market Research Report 2033. - Electrical and electronic applications for BMC reached USD 0.57 billion in 2024, according to Market Data Forecast. - The automotive engine encapsulation market, which includes BMC motor covers, is projected to reach USD 3.7 billion by 2030, according to Grand View Research. - Asia Pacific held a 45% share of the global railway composites market in 2025, with SMC used for lightweight interior parts, according to Railway Composites Market Forecast. - Non-metallic battery housings held the major share of the market in 2023 because of lightweighting and thermal insulation benefits, according to GlobeNewswire / ResearchAndMarkets.

Between the lines: - Zhejiang Aobang is positioned more as a GFK composite specialist than a direct molded BMC or SMC parts supplier. - Buyers seeking custom battery housings, terminal blocks or water treatment housings should verify whether a supplier’s material profile matches the project specification. - The strongest competitive signals in this market are not just material claims but also tooling capability, certification coverage and after-sales support. - The article’s supplier list suggests that China’s composite market is broad, but capability levels vary by company and product type.

What's next: - Procurement teams are likely to focus on test reports, compliance documentation, tooling support and warranty terms before awarding contracts. - Buyers evaluating BMC components for high-voltage electrical enclosures should check UL 94 V-0 requirements. - European buyers should also confirm EN 62841 and IEC compliance for electrical enclosures and terminal blocks. - Zhejiang Aobang says its process includes pre-sales technical review, full inspection before factory delivery and after-sales follow-up visits. - Zhejiang Aobang also says it offers a 400,000-shot mold warranty with free replacement for non-human-induced quality defects and on-site installation guidance. - For cleanroom panels, Zhejiang Aobang says it offers a 2- to 5-year warranty and free replacement for non-human-induced quality defects. - The company flags two operating risks for cleanroom panels: accelerated aging above 100°C and surface damage from heavy impact by sharp objects.

The bottom line: - China’s BMC and SMC supplier base is expanding alongside EV, rail and electrical demand, but buyers still need to match each manufacturer’s material, tooling and certification profile to the end use.
