120mm Thermoformed Curved Acrylic Sheets: Creating Immersive Large Curved Acrylic Swimming Pools
In the design of high-end cultural tourism hotels, luxury villas, popular scenic venues and infinity water spaces, linear swimming pools can no longer meet people’s pursuit of aesthetics and immersive experience. 120mm thick acrylic sheets molded by precision thermoforming technology can form smooth curves, soft curved surfaces and seamless arc corners as a whole. Currently, they serve as the core material for manufacturing large curved acrylic swimming pools, suspended infinity pools and curved viewing pools. Balancing excellent structural safety, ultra-transparent vision and sleek curved aesthetics, they perfectly satisfy the pressure resistance requirements and artistic design demands of large swimming pools.
I. Why 120mm Thermoformed Acrylic Is the First Choice for Large Curved Swimming Pools
Large swimming pools feature large water capacity and wide water depth ranges, and the pool side walls need to withstand long-term high-strength hydrostatic pressure. Meanwhile, curved structures impose extremely high requirements on the toughness, uniformity and forming accuracy of plate materials. The 120mm thick cast acrylic sheet, paired with professional thermoforming technology, fully meets the strict service standards of large curved swimming pools, with far superior performance compared with traditional glass and ordinary thin acrylic sheets.
1. Standard Thickness for Full Pressure Resistance and Safety
The 120mm thick acrylic is an engineering-grade cast sheet with a dense and uniform molecular structure, free of bubbles, delamination and impurities, delivering stable physical properties. Compared with conventional thin acrylic sheets, it boasts greatly improved water pressure resistance, impact resistance and deformation resistance. Suitable for large swimming pools with a water depth of 3 to 6 meters, it can withstand long-term static water pressure of large water areas without bulging, deformation, cracking or leakage. Featuring excellent toughness, it resists water flow impact, human collision and ambient temperature changes. With a far higher safety factor than traditional tempered glass, it completely eliminates hidden dangers such as spontaneous breakage and falling fragments of glass.
2. Thermoforming Technology for Minimalist Curved Aesthetics
Ordinary hard plates cannot achieve integrated curved molding, and spliced structures produce obvious gaps, which not only damage the overall appearance but also easily cause water seepage, scale accumulation and aging leakage. In contrast, 120mm acrylic sheets have excellent thermoplastic formability. Through precise constant-temperature thermoforming, they can be customized into arbitrary radians, curved surfaces and arc corners according to design requirements, realizing integrated curved molding of pool side walls, viewing facades and infinity water retaining walls. The sleek and rounded curved lines replace rigid right angles, creating a natural, soft and high-end minimalist visual effect, perfectly adapting to personalized designs such as curved suspended pools, annular pools and curved viewing pools.
3. High Optical Transparency for Immersive Infinity Vision
Made of high-end aquarium-grade cast raw materials, 120mm thermoformed acrylic sheets have a light transmittance of over 92%, with a refractive index highly close to that of water. Even with a thickness of 12 centimeters, the sheets remain crystal clear and distortion-free without fogging. After thermoforming, the curved surface features uniform light transmission without light and shadow faults or local blurring. The clear water scenery can be fully viewed from the outside, and an unobstructed wide-angle view is available inside the pool, perfectly presenting the immersive visual effect of “integrated water and sky, suspended infinity”. It is the core highlight of Internet-famous infinity pools and high-altitude curved viewing pools.
4. Weather Resistance and Durability for Long-Term Underwater Use
120mm curved acrylic sheets after thermoforming shaping and annealing treatment have greatly enhanced structural stability, with excellent UV resistance, aging resistance, hydrolysis resistance and acid-base corrosion resistance. Long-term immersion in water and exposure to outdoor sunlight will not cause yellowing, fogging, discoloration or deformation. Resistant to intense sunlight, frost and seasonal temperature changes, the sheets have a service life of 15 to 20 years. Only simple polishing maintenance is required to restore a brand-new texture, resulting in extremely low operation and maintenance costs.
II. Core Manufacturing Process of 120mm Curved Acrylic Swimming Pools
Large curved acrylic swimming pools demand extremely high processing precision. The thermoforming of 120mm thick sheets differs from ordinary thin sheet processing, requiring multiple precision procedures including shaping, temperature control, stress relief, optical polishing and sealing to ensure forming accuracy and structural safety.
1. Material Selection and Preprocessing
We adopt 120mm one-piece cast acrylic sheets made of imported raw materials, strictly inspecting the internal quality to eliminate defects such as bubbles, impurities and cracks. The sheets are precisely cut to required pool sizes with edge chamfering and fine grinding to eliminate stress concentration points, laying a foundation for subsequent thermoforming.
2. Constant-Temperature Precision Thermoforming
This is the core procedure of curved pool molding. The cut 120mm thick sheets are sent to a professional constant-temperature thermoforming furnace. The temperature and heating duration are accurately adjusted according to the designed radian, and segmented uniform heating is adopted to soften the sheets evenly, avoiding local overheating deformation and inconsistent internal and external radian. Custom curved molds are used for precise compression shaping to ensure standard radian, flat curved surface and overall symmetry with millimeter-level errors, fully matching the overall pool design scheme.
3. High-Temperature Annealing for Stress Relief
Thick sheets are prone to internal stress after thermoforming, which may lead to cracking and deformation in subsequent use if not handled properly. Therefore, the molded curved sheets must undergo constant-temperature annealing treatment to slowly release internal processing stress and stabilize the molecular structure. This greatly improves the deformation and crack resistance of the sheets, ensuring the long-term structural stability of large swimming pools.
4. Double-Sided Precision Optical Polishing
After thermoforming and annealing, both the internal and external surfaces of the curved sheets are polished through multiple fine grinding and optical polishing processes to eliminate processing traces, micro scratches and fog layers. The overall curved surface achieves uniform light transmission and ultimate optical texture without visual distortion, guaranteeing an all-round excellent viewing effect of the swimming pool.
5. Seamless Splicing and Waterproof Sealing
Large curved swimming pools are assembled with multiple 120mm thermoformed curved sheets. Special optically matched acrylic adhesive and vacuum pressure curing technology are adopted to completely eliminate bubbles and water seepage risks at splicing gaps. Secondary fine polishing and leveling are carried out after bonding to achieve invisible joints. Marine-grade double sealing technology is applied at the connection of pool walls, steel structures and concrete bases to withstand long-term water pressure impact and completely prevent water leakage and seepage.
