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

China’s BMC and SMC composite supply chain is gaining attention as demand rises in automotive, electrical and rail applications. A new profile highlights Zhejiang Aobang Technology and four other manufacturers, while noting buyers should verify specs, tooling and compliance before sourcing.

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 the largest regional share of the market in 2025 at 63.0%, according to Grand View Research. - China remains a major sourcing base because of its composites manufacturing clusters and electric vehicle production capacity. - Buyers in automotive, electrical, rail and industrial equipment need suppliers that can meet flammability, durability and tooling requirements.

What happened: - The article profiles five Chinese manufacturers active in the BMC and SMC ecosystem. - Zhejiang Aobang Technology Co., Ltd. is the primary focus. - The other companies listed are 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. - Zhejiang Aobang Technology is based in Deqing County, Huzhou City, Zhejiang Province, and was founded in 2010. - The company focuses on GFK glass-fiber reinforced materials used in composite applications that overlap with BMC and SMC use cases.

The details: - BMC is supplied in bulk form, while SMC is supplied as a sheet. - Both materials are glass-fiber reinforced thermoset composites processed mainly by compression molding. - BMC and SMC are valued for mechanical strength, dimensional stability, flame retardancy and corrosion resistance. - Polyester-based BMC held a 65% share in 2024, valued at about USD 1.37 billion, according to Market Research Intel. - Common applications include BMC motor encapsulation, SMC EV battery housings, SMC electrical enclosures, insulating components, lightweight auto parts and railway transportation parts. - Glass fiber accounted for 62.1% of the total fiber segment in the SMC/BMC industry in 2025, according to Grand View Research. - Zhejiang Aobang operates a 20,000-square-meter factory and employs 150 people. - The company’s main product is the ARF Antibacterial Board, a GFK composite panel made from polyester resin, glass fiber and filler. - The panel comes in sizes from 300×300 mm to 600×1500 mm. - Surface options include high gloss, coarse texture, wood grain, brushed texture, special-shape and sound-absorbing variants. - The panel is formed through high-temperature de-moulding and one-piece on-line lamination. - The panel composition includes glass fiber, flame-retardant resin, aluminium hydroxide and silver-containing antibacterial agents. - Zhejiang Aobang says the panel achieves 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. - The company says the panel provides thermal and sound insulation and can reduce power consumption by 15% because of its thermal insulation performance. - Zhejiang Aobang introduced industrial GFK product technology from Germany in 2010 and later developed proprietary GFK technologies through independent R&D. - The company holds ISO environmental management system certification and ISO quality management system certification. - Zhejiang Aobang is also recognized as a National High-Tech Enterprise and holds multiple invention and utility model patents. - Its main markets are the EU and China. - The company’s products are used in hospitals, schools, banks, high-speed-rail stations and other public venues. - Ningbo Huayuan New Materials is located in Ningbo, a port city with dense composite materials and automotive parts supply chains. - Jiangsu Zhaoyun New Materials operates in Jiangsu, a major 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 strong. - Zhejiang Sansheng Mould & Plastic Technology combines mould design and plastic technology, which is relevant to compression-molded BMC and SMC parts.

Between the lines: - Zhejiang Aobang’s GFK panel line is not a direct substitute for custom BMC or SMC molded parts. - Buyers seeking battery housings, electrical terminal blocks or water-treatment housings should confirm whether the material profile fits the project or whether custom molding is available. - The broader market data points to strong demand in EV batteries, transportation and electrical enclosures. - Automotive applications represented the largest BMC end-user segment in 2024 at 38%, 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 EV 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 2024, driven by EV adoption, according to Market Research Report 2033. - Electrical and electronic BMC applications 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 housings held the major market share in 2023 because of lightweighting and thermal insulation benefits, according to GlobeNewswire / ResearchAndMarkets.

What's next: - Buyers are likely to keep comparing suppliers on material specifications, certification records, tooling capability and after-sales support. - UL 94 V-0 remains a key flammability requirement for BMC components used in high-voltage electrical enclosures. - EN 62841 and IEC standards are important for electrical enclosures and terminal blocks made from BMC materials in Europe. - Zhejiang Aobang says it uses pre-sales technical review, full inspection before factory delivery and post-sale follow-up visits. - The company says it offers a 400,000-shot mold warranty with free replacement for non-human-induced quality defects. - Zhejiang Aobang also says professional technicians provide on-site installation guidance. - For cleanroom panels, the company flags accelerated aging above 100°C and damage from sharp impact as risks. - Zhejiang Aobang says it offers a 2–5 year warranty and free replacement for non-human-induced quality defects for cleanroom panels.

The bottom line: - China’s BMC and SMC supply base is broad, but buyers need to match each supplier’s actual process capabilities to the part they need. - Zhejiang Aobang stands out for vertically integrated GFK production, certifications and documented performance, while the other four companies add regional depth to China’s composite manufacturing network. - The company’s official website is More information.
