Tongzi Office Chair Materials
The main materials of the Tongzi office chair (model olm442) include the back frame, seat cushion, writing board, base feet, and casters, with the material characteristics of each component as follows:
The back frame is molded in one piece using brand-new PP (polypropylene) + 30% glass fiber (GF) through injection molding. PP is a thermoplastic resin with characteristics such as low density, chemical resistance, and strong impact resistance. After adding 30% glass fiber, the material's mechanical strength, rigidity, and heat resistance are significantly improved, enabling it to withstand the pressure and friction of daily use while remaining lightweight for easy handling and adjustment. The one-piece molding process reduces stress concentration at component connections, enhancing the overall stability and durability of the back frame.
The seat cushion is made of high-density pure cotton material, with the outer seat fabric available in four colors: gray, blue, yellow, and orange. High-density pure cotton offers excellent elasticity and breathability, evenly distributing body pressure for a comfortable sitting experience that remains resistant to deformation over extended use. The variety of seat fabric colors meets the decorative needs of different office environments, allowing users to choose a matching color scheme based on their space style.
The writing board is made of ABS plastic sheet, equipped with an aluminum alloy rotating mechanism, and the support frame uses high-quality โ 32 round tube (2.0mm thickness). ABS plastic has characteristics such as high strength, impact resistance, and ease of processing, making it suitable for writing boards that require frequent opening and closing. The aluminum alloy rotating mechanism is lightweight and corrosion-resistant, ensuring smooth rotation of the writing board. The round tube design of the support frame enhances structural stability, and the 2.0mm thickness guarantees sufficient load-bearing capacity for safely placing laptops or documents.
The base feet are molded using a nylon chassis through injection molding, with the footrest featuring an ABS storage tray. Nylon material has characteristics such as wear resistance, aging resistance, and self-lubrication, making it suitable for chasses that require frequent movement. The design of the storage tray adds practicality, allowing temporary storage of small items such as pens and notepads, improving office efficiency.
The casters are ฮฆ50mm nylon wheels with a PU surface. The 50mm diameter ensures smooth movement while balancing stability and flexibility. The nylon wheel core is wear-resistant and quiet, and the PU (polyurethane) outer layer further reduces sliding noise and enhances floor protection, making them suitable for use on hard floors such as wooden and tiled floors.
