The core technology of the hollow blow-molded backrest seat lies in the "hollow blow molding process." This process involves heating thermoplastic plastics such as high-density polyethylene (HDPE) or polypropylene (PP) to a molten state, injecting it into a mold, and then using high-pressure air blow molding to form a hollow interior and a dense surface structure. Seats produced using this process offer many advantages, such as lightweight design: the hollow structure significantly reduces the seat's weight, facilitating handling and installation while maintaining strength; high strength and toughness: the tightly packed linear structure of HDPE gives it a crystallinity of 80%-90%, resulting in superior impact resistance compared to traditional solid plastics, meeting the needs of people of all body types; and excellent weather resistance: the formula with added UV absorbers and antioxidants ensures the seat remains undeformed and crack-free in extreme temperatures ranging from -20℃ to 80℃, and exhibits excellent resistance to UV aging, with an outdoor lifespan exceeding 15 years.
The backrest design is one of the product's key highlights. By mimicking the curve of the human spine, the seat back features a 105°-110° tilt angle, combined with a lumbar support structure, effectively distributing pressure during sitting. The backrest features staggered ventilation holes, and the bottom utilizes hollowed-out support ribs to create air convection channels, keeping the seat dry even after prolonged use. The hollow structure provides moderate elasticity, and combined with the wraparound curved design, it offers dual comfort: lumbar support and back wrapping.
The functional design of the hollow blow-molded backrest seat fully considers the actual needs of venue operation: using expansion bolts for ground fixing, and various installation methods such as flat mounting, side mounting, and vertical beam mounting, standardized components can be quickly assembled, significantly shortening the construction cycle. A drainage and moisture-proof system: drainage holes and a ring-shaped retaining ring at the bottom form a double-channel structure to prevent water accumulation during rainy days. This design is particularly effective in open-air stadiums and temporary performance venues. Maintenance is convenient: the smooth, seamless surface design effectively prevents stain penetration; cleaning only requires wiping with a neutral detergent, significantly reducing maintenance costs compared to traditional seats.
Hollow blow-molded backrest seats can be widely used in the following scenarios: Sports venues: In large venues such as football fields and basketball courts, their impact resistance and weather resistance can withstand high-frequency use and inclement weather; the lightweight design facilitates integration with electric retractable grandstand systems, enabling rapid deployment and storage; Educational institutions: School auditoriums and lecture halls using this type of seat not only meet the needs of students' group activities, but also reduce maintenance difficulty through moisture-proof and easy-to-clean properties; Temporary events: In scenarios such as concerts and exhibitions, its modular design supports quick assembly and disassembly, and the folding function can save more than 50% of transportation space.
