HM-575 Foshan hemmy aluminum alloy school chair

Next step: Made of aluminum alloy integrated die-casting, without burrs or welding, the surface is treated with anti oxidation and high-temperature spray coating, with strong adhesion, impact resistance, corrosion resistance, rust resistance, fade resistance, and durability

Upper seat back frame: The upper part is made of high-quality round tube, which is bent by mold pressing angle, with a diameter of φ 30mm. The circular tube with a wall thickness of 1.5mm is welded to the rear support tube as a whole, ensuring strong firmness; The surface has been treated with spray coating.

Chair seat: made of high-density polyethylene hollow blow molding (raw material is HDPE high-density polyethylene), which is a high crystallinity, non-polar thermoplastic resin. The surface of HDPE in its original state is milky white, with a certain degree of translucency in its thin section. High density polyethylene is a non-toxic, odorless, and odorless particle. Additional auxiliary materials such as anti ultraviolet and oxidant can be added. The product has strong impact resistance, strong ultraviolet resistance, and long life. It is warm in winter and cool in summer, and has good heat resistance. According to the ergonomic design, it adopts the arc concave design, which makes it comfortable to sit, has surface texture treatment, is green, environmentally friendly, has high hardness, strong toughness, and is wear-resistant, scratch resistant, anti pollution, anti-aging, compression and impact resistant.
