Graphic Details
a strong design team and technical elites with more than 20 years of experience, the company strives to create high-quality public seats to provide high-quality and low-cost seats for domestic and foreign government agencies
Specifications: center distance 540mm, back height 1000mm, seat height 450mm; Seat depth 580mm, total depth 740mm
Seat/back shell: select pockmarked PP engineering plastic shell, injection molding by injection molding machine and with internal reinforcement structure. The seat shell is provided with sound-absorbing holes, the number of which reaches more than 420. The physical and mechanical properties of the seat/back sponge with sound-absorbing function are less than or equal to 5% and 46% in the state of 75% compression permanent deformation.
Seat armrest frame: cold rolled plate is used for stamping and welding by die, and the surface is sprayed with plastic powder at high temperature. The upper end of the frame is 405mm ± 5mm long, the lower end is 245mm ± 5mm long, the width is 85mm ± 5mm, and the height is 350mm ± 5mm. Its mechanical properties: tensile strength (Rm) 464MPa
Aluminum alloy tripod: the use of aluminum alloy through the mold injection molding, tripod surface is smooth without burrs, the whole without welding traces, high temperature spraying treatment, to ensure that the tripod corrosion resistance, no rust, no fading. Total height of tripod: 235mm ± 12mm, wall thickness: 3±0.5mm, size of connection between top of tripod and armrest frame: 161mm ± 2mm long, 50mm ± 2mm wide and 13mm ± 0.5mm thick; Total length of footplate: 372mm ± 2mm, width under footplate: 62mm ± 2mm. The front end of the tripod is semicircular and round, with the inner space height of 121mm, width of 39mm, column width of 133mm ± 2mm, semicircle length of 170mm ± 2mm, and the highest point of 55mm ± 2mm. The distance between the front and back holes of the foot plate anchor holes is 340mm ± 2mm.
Installation method: ground fixing: all connecting screws are carburized and hardened. the chair foot and the ground are firmly connected with Ø12mm explosive glue and M8 × 60mm self-tapping, which is durable and has no shaking feeling.
Specification: 620W*765D*1020MM 1. Back foam: High-density cold-foamed PU shaped foam with a density of 45-55KG/M3 is used. 2. Seat sponge: High-density cold-foamed PU shaped sponge is used, with a sponge density of 55-60KG/M3. 3. Back inner panel: Made of high-quality plywood, it is bent and shaped using molds. The appearance is curved, elegant, and beautiful, exhibiting the aesthetic of curves. 4. Back panel: It is made of high-quality high-density hardwood plywood, molded by injection molding. It is externally covered with high-grade beech wood veneer and treated with high-grade polyester paint. The appearance is curved, elegant, and beautiful, with a sense of curve. Dimensions: length is 760mm, width is 510mm, and thickness is 15mm. 5. Seat outer panel: Made of high-quality high-density hardwood plywood, it is molded through mold pressing. The outer surface is covered with high-grade beech wood veneer and treated with high-grade polyester paint. Dimensions: Length is 440mm, width is 430mm, and thickness is 15mm. 6. Restoration mechanism: The seat cushion adopts a damping restoration mechanism, with sound-absorbing holes on the surface of the seat plate, ensuring a smooth restoration without impactful collisions, making it suitable for use in settings where high audio quality is required. 7. Handrail: crafted from high-quality solid wood, with a width of 60mm, the surface undergoes polishing, rust removal and phosphating, and electrostatic powder coating. 8. Fabric: Made of high-quality, specialized fabric, it features resistance to stains, fade resistance, anti-static properties, comfortable hand feel, and remains wrinkle-free even after prolonged use 9. Base: The chassis of the air duct assembly is stamped and formed from 2.0mm high-quality cold-rolled steel plate, with a diameter of 270mm. The column is also stamped and formed from 2.0mm high-quality cold-rolled steel plate, with a diameter of 200mm. The base assembly is stamped and formed from 2.0mm high-quality cold-rolled steel plate, and the seat support assembly is welded and formed from 25*25*2.0 high-quality cold-drawn square tubes and 2.0mm high-quality cold-rolled steel plates. All welding parts undergo processes such as grinding, rust removal and phosphating, electrostatic powder coating, and high-temperature baking. (Optional air supply function) 10. Seat shape: The overall design follows ergonomic principles, with continuous protruding backrest and lumbar support on both sides of the seat back sponge (effectively alleviating fatigue caused by prolonged sitting). 11. Sturdy ground: Electrostatic spraying is used for the hexagonal expansion screws, which are resistant to rust. Additionally, dustproof covers are added for an elegant appearance.
