Company Overview - Silver Power Transmission Technology Co., Ltd. was established in 2003 in Yinchuan, with over 1,000 employees. The main business includes R&D, production, and sales of wind power gearboxes and other precision transmission solutions for the renewable energy industry. The company officially listed on the Shenzhen Stock Exchange's Growth Enterprise Market in August 2023 [2][3]. Market Outlook - The global and Chinese wind power installation scale is continuously expanding, establishing a solid demand foundation for the wind power gearbox market. The Global Wind Energy Council (GWEC) projects that from 2025 to 2030, the global wind power installation capacity will reach 981 GW, averaging 164 GW per year. This significant scale will directly drive the demand for core components like wind power gearboxes [3]. - In the first half of 2025, China's newly installed wind power capacity reached 51.39 GW, a year-on-year increase of 98.88%. The market for wind power gearboxes in China is expected to grow rapidly alongside installation volume, with the market size projected to increase from approximately $3.136 billion in 2023 to $4.263 billion by 2030 [3]. Smart Factory Development - As of August 2025, the company has invested a total of 1.231 billion yuan in the wind power gearbox smart factory. The construction of the factory is progressing smoothly, with all civil engineering completed and core production equipment arriving on site [4]. - The factory is currently in a critical construction phase, focusing on equipment debugging and process verification to ensure efficient production flow and prepare for large-scale production [4]. Production Capacity and Challenges - The smart factory is in the initial ramp-up phase, with three main factors affecting full capacity release: the production team's operational proficiency, optimization of production line connections, and ongoing equipment debugging [4]. - The company plans to gradually increase production capacity as these factors stabilize, aiming to reach design capacity over time [4]. Product Advantages - The company's gearboxes feature advantages such as smooth engagement, low noise, good sealing performance, high efficiency, lightweight, and low cost, attributed to advanced technology and processes [5]. - The use of high-quality alloy steel and advanced heat treatment processes enhances the durability and fatigue life of the gears, while precision machining ensures low noise and high efficiency [5]. Profitability Expectations - The smart factory is expected to significantly improve gross margins through product value addition and scale effects. The high value of wind power gearboxes positions them for higher gross margins compared to conventional products [5]. - The intelligent production line is anticipated to enhance processing precision and yield, reducing waste and lowering unit costs, which will positively impact the overall gross margin as production capacity and market share increase [5].
