DEZHOU, China - Shandong Shuangyi Technology Co., Ltd. has recently completed the production and delivery of a custom-designed 10MW nacelle cover for an overseas client, marking another milestone in the company's large-scale composite component manufacturing capabilities.

The 10MW nacelle cover is a large-scale, high-thickness customized product. The company's technical team upgraded the traditional hand lay-up process to a vacuum bag process. While strictly meeting the client's specified thickness requirements, this upgrade significantly improved the overall density and structural strength of the product, resulting in a more uniform and consistent net shape. The innovation successfully resolved industry-wide challenges associated with thick-walled products, including susceptibility to deformation and insufficient strength.

Given the highly customized nature and large overall dimensions of the component, the production process was prone to unforeseen issues that could lead to cost overruns and project delays. To address this, the technical team conducted advance sample trials and developed a comprehensive set of production plans and contingency measures. This proactive approach effectively mitigated quality risks and material waste during large-scale production, maximizing cost savings and significantly compressing the production cycle.

To deliver on its quality commitment, the technical team utilized high-precision professional equipment, including laser scanners, to conduct comprehensive measurements and repeated calibrations of tooling dimensions, structure, and curvature. After multiple rounds of fine-tuning, the team achieved a 100% perfect match between the tooling and the final product.

During the manufacturing phase, the team faced challenges related to the nacelle's significant height, the difficulty of installing large metal frames on the top section, and the complexities of integrated forming. The production and technical departments collaborated closely to simulate construction processes and ultimately built a dedicated welding platform. This innovative approach successfully overcame the difficulties of high-altitude installation and integrated welding forming, achieving a seamlessly integrated finished product.
