As a professional acrylic manufacturer and engineering service provider, Leyu specializes in large custom acrylic structures, complex curved viewing windows, pressure-bearing aquatic structures, and large-scale seamless acrylic installations.

For this project, Leyu provided comprehensive acrylic engineering services covering customized production, precision processing, transportation coordination, on-site installation, sealing, commissioning, and after-sales support. The project demonstrates Leyu’s capabilities in thick acrylic panels, large curved structures, panoramic viewing systems, and complex aquarium environments.

Chengdu Panda Ocean Park Acrylic Project

Chengdu Panda Ocean Park officially opened in 2026. The project includes a variety of themed aquatic environments and immersive viewing spaces, covering entrance landscapes, themed exhibits, polar animal displays, deep-sea themed areas, and immersive underwater routes.

For an aquarium of this scale, acrylic is not simply a transparent viewing material. Large acrylic panels must simultaneously meet requirements for optical clarity, structural stability, pressure resistance, forming precision, waterproofing, and long-term operation.

As the acrylic engineering contractor, Leyu participated in the production and installation of the project’s core acrylic aquatic structures.

From the initial site survey and structural coordination to factory fabrication, transportation, on-site assembly, precision joining, sealing, and commissioning, Leyu implemented a standardized engineering process to ensure that each acrylic structure matched the project’s design and construction requirements.

Professional Site Survey and Project Coordination

Before production began, Leyu carried out a professional site survey and coordinated the acrylic structures with the civil works and overall construction schedule.

Large acrylic structures are closely connected with steel structures, concrete structures, waterproofing systems, lifting operations, and other trades. Any deviation in the early stages can increase installation difficulty or affect the final viewing effect.

Therefore, Leyu optimized the acrylic structure and installation approach in advance according to the actual site conditions.

For oversized and extra-thick acrylic components, Leyu also developed corresponding transportation and protection plans to ensure that the components could arrive safely and on schedule.

This early coordination helped reduce installation risks and provided a reliable foundation for subsequent construction.

Main Hall: Large 90-Degree Curved Acrylic Viewing Window

One of the highlights of the project is the large curved acrylic viewing window in the main hall.

The viewing window is nearly 7 meters wide and features a 90-degree right-angle curved structure.

Compared with a conventional flat acrylic panel, this type of structure requires much higher forming precision. The large-angle curved geometry must maintain consistent curvature while controlling internal stress and dimensional accuracy.

Leyu used a customized large-scale forming process to manufacture the acrylic structure, ensuring smooth curved lines and stable overall geometry.

The result is a large transparent viewing interface that integrates naturally with the surrounding aquarium environment while providing visitors with a wider underwater viewing experience.

Panoramic Acrylic Cylindrical Tank

Another popular attraction is the panoramic acrylic cylindrical tank, with a diameter of more than 5 meters and a height of approximately 4.5 meters.

The cylindrical structure requires high precision throughout the forming, joining, polishing, and installation processes.

Leyu customized the acrylic structure according to the tank geometry and adopted an overall curved seamless joining solution to achieve a smooth and uniform cylindrical appearance.

The 360-degree viewing design allows visitors to observe the aquatic environment from multiple directions.

For long-term operation in an aquarium environment, Leyu also used a customized UV- and aging-resistant acrylic formulation. Combined with high optical transparency and precision polishing, the acrylic maintains a clear viewing effect under long-term aquarium lighting.

This helps reduce common problems such as yellowing, haze, and reduced transparency during long-term use.

12-Meter Panoramic Acrylic Viewing Window

The project also includes a panoramic acrylic viewing window approximately 12 meters wide.

The large viewing interface provides visitors with a broad, unobstructed view of the beluga habitat and performance area.

For such a large pressure-bearing acrylic structure, both material performance and installation accuracy are critical.

Leyu controlled the production and installation processes according to the project requirements, including acrylic fabrication, structural alignment, joining, sealing, and staged commissioning.

The completed viewing window provides a wide and clear viewing interface while maintaining the structural stability required for year-round operation.

Immersive Acrylic Underwater Tunnel

Leyu was also responsible for the acrylic enclosure and viewing windows used along the project’s immersive route.

The system includes customized acrylic panels and sealing structures designed for freshwater ecological environments.

These acrylic structures are used in areas including the sturgeon pool, interactive touch pool, and surrounding aquatic systems.

Through the combination of transparent acrylic panels and integrated curved structures, the viewing route creates a more natural and immersive experience.

Instead of simply looking at an aquarium from outside, visitors can move through the space and observe the aquatic environment from different angles.

For this type of immersive structure, acrylic provides an important advantage: it can be customized into large curved and complex geometries while maintaining excellent optical clarity.

Deep-Sea Themed Zone

The deep-sea themed zone is another important part of the project.

Leyu provided the complete acrylic system for this area, including the seawater viewing tunnel, approximately 15-meter-long curved viewing window, and 90-degree three-dimensional corner viewing window.

Compared with conventional flat viewing windows, these structures involve more complex three-dimensional geometries and higher requirements for structural and sealing performance.

For large marine animals such as sharks and sea turtles, the viewing interface must provide a sufficiently wide field of vision while remaining stable under long-term water pressure.

Leyu developed customized structural and sealing solutions according to the actual requirements of the project.

High-precision joining and strict waterproofing control were applied to the acrylic structures to ensure reliable performance during long-term commercial operation.

Leyu’s Key Acrylic Engineering Capabilities

The Chengdu Panda Ocean Park project demonstrates several of Leyu’s core technical capabilities.

1.High-Transparency, Weather-Resistant Acrylic

For aquarium applications, optical performance is one of the most important requirements.

Leyu uses high-transparency optical-grade cast PMMA for large aquarium structures. For outdoor or long-term lighting environments, customized UV- and aging-resistant formulations can also be applied according to project requirements.

With light transmittance above 92%, the material provides a clear viewing experience while helping reduce optical distortion.

For large underwater viewing windows, this is particularly important because even minor optical distortion can affect the visitor’s perception of the aquatic environment.

2. High-Precision Thermoforming

Complex acrylic structures require precise thermoforming technology.

For different structures, Leyu adjusts heating, forming, and cooling parameters according to the required geometry.

This helps control internal stress and reduce problems such as springback, whitening, and deformation.

For large curved viewing windows, precision forming ensures that the final geometry remains consistent with the design while maintaining smooth and continuous curved lines.

3. Large-Scale Seamless Joining

Large acrylic structures cannot always be transported as a single piece.

For oversized components, Leyu uses professional joining technologies to assemble multiple acrylic sections into larger structures.

The joining process requires strict control of alignment, bonding conditions, polishing, and surface finishing.

For aquarium applications, the goal is not only to create a visually continuous surface but also to maintain structural integrity and reliable sealing performance under long-term water pressure.

4. Standardized Quality Control

Quality control is implemented throughout the entire production and installation process.

Before shipment, acrylic components undergo processes including casting, stress relief, precision forming, double-sided polishing, and simulated factory water-pressure testing where required.

For oversized or irregular components, Leyu develops special transportation and protection plans based on their dimensions, shape, and transportation conditions.

After arrival at the project site, standardized procedures are followed for lifting, positioning, alignment, joining, sealing, and staged water filling and pressure testing.

This allows the structural and waterproofing performance to be verified before final acceptance.

5. High Toughness and Easy Maintenance

Acrylic is also valued for its toughness and repairability.

For large public aquatic facilities with high visitor traffic, minor surface scratches may occur during long-term operation.

Professional polishing can repair many minor scratches and restore the surface finish without replacing the entire acrylic panel.

This helps extend the service life of the acrylic structure and reduce long-term maintenance costs.

Professional Acrylic Installation by Leyu

Large acrylic structures require more than manufacturing expertise. Installation accuracy is equally important.

For the Chengdu Panda Ocean Park project, Leyu’s professional installation team participated in transportation coordination, lifting, positioning, joining, sealing, and commissioning.

Large acrylic components must be accurately aligned with surrounding civil and steel structures.

During installation, the team carefully controlled the position and geometry of each component before proceeding with joining and sealing.

For large viewing windows and curved structures, even small installation deviations can affect the final appearance and sealing performance. Therefore, Leyu applies standardized installation procedures to improve construction efficiency and reduce on-site risks.

Acrylic Protection and Transportation

Before shipment, acrylic surfaces are protected with PE film to reduce the risk of scratches and contamination during transportation and installation.

Depending on the size, shape, and transportation conditions of the component, Leyu can also use KT-board wooden crates or additional iron-frame packaging for enhanced protection.

For oversized acrylic components, transportation planning is coordinated in advance to ensure safe delivery to the project site.

This is particularly important for large curved acrylic structures, which may have irregular dimensions and require special handling during loading, transportation, unloading, and lifting.

Long-Term Maintenance and After-Sales Service

Leyu’s service does not end after installation.

For large acrylic aquarium projects, long-term maintenance is an important part of the overall engineering service.

Leyu provides professional technical support for acrylic maintenance, including surface inspection and professional polishing of minor scratches.

For large aquatic facilities, regular inspection and proper maintenance can help preserve the optical quality and appearance of acrylic viewing windows over the long term.

Through integrated manufacturing, installation, maintenance, and after-sales support, Leyu provides a complete service chain for large acrylic aquarium projects.
