office chair back support frame
With 20 years of R&D and production focus on plastic office chair accessories, the office chair back support frame is the core structural component that stabilizes the stress bearing of the entire backrest. The annual export shipment volume of office chair back support frames remains stable at 180,000 pieces, widely sold to furniture procurement markets across the Middle East, Southeast Asia and Latin America.
Ordinary support frames available on the market feature thin structures prone to fracture and mesh fabric detachment under single-point stress. We re-optimize the mechanical stress bearing points of the office chair back support frame with a multi-point balanced stress design, thickening raw materials on support crossbeams and side buckle positions, paired with integrated injection molding of tough nylon. No loose buckles or bracket fractures occur during static daily leaning or frequent large-angle reclining, greatly cutting after-sales maintenance rates for end products.
Our in-house mold R&D workshop independently develops and produces each set of office chair back support frames with unified standardized buckles and screw holes, compatible with most mainstream mesh and sponge backrests. Overseas assembly factories can directly assemble finished products without secondary hole drilling after receiving goods.
We have long supplied office chair back support frames for the full product line of brand GLOBAL. After tens of thousands of repeated opening and closing tests, the support structure remains free of loosening and deformation, with long-term repeat purchase proportion exceeding 80% among overseas distributors. As a source manufacturer without middleman markup, tiered discounts apply to bulk purchases. Multiple types of backrest plastic accessories can be mixed in a single order to reduce one-time ocean freight stocking costs and inventory pressure for clients.

Customization Capabilities
Full OEM/ODM personalized customization services are supported. Exclusive office chair back support frames can be separately developed based on engineering drawings or physical samples provided by clients. The complete development cycle for customized samples ranges from 30 to 45 days. Free physical samples are sent for clients to conduct performance testing after sample confirmation. Mass production can commence once the order reaches the minimum order quantity of 500 pieces. Mixed batches of support frames in different colors and sizes are allowed in a single order to meet multi-product stocking demands of agents.
For overseas buyers with private brands, original product logos can be removed and exclusive brand logos of clients can be printed, suitable for sales on overseas online stores and offline physical retail outlets. Over the years, we have completed customized development of exclusive accessories for dozens of overseas furniture brands.

Factory Strength
Founded in 2005, we have 20 years of production experience in plastic furniture accessories. The factory covers an area of 6,000 ㎡ with 50 permanent production employees, and the monthly output of all plastic chair accessories reaches 250,000 pieces.
The workshop is fully equipped with injection molding machines, CNC and EDM complete mold processing equipment, as well as professional testing instruments for backrest pressure, impact and fatigue. All processes including mold manufacturing, injection molding and finished product testing are completed in-house without outsourced processing, enabling full control of product quality and delivery schedules. Conventional in-stock models can be shipped within 7 days, while mass production of customized products takes 7 to 10 days. Sufficient production capacity supports large full-container overseas orders and consistent supply to clients in Southeast Asia, the Middle East and South America, eliminating delivery delays.
Quality Control System
The factory has established a complete standardized quality management system. After each batch of office chair back support frames is off the production line, 10% of finished products are sampled for three tests: load-bearing capacity, impact resistance and buckle firmness. Non-compliant products are fully reworked and never enter the packaging process. Third-party inspection institutions are welcome to conduct on-site quality inspections during production, and qualified sampled products are separately packaged in isolated areas.
All product series come with a unified 2 to 5-year warranty. If goods are damaged during logistics transportation or have inherent material and process defects, we will fully bear the costs of re-delivery, return and replacement of products and logistics once responsibility is confirmed to lie with us. Dedicated multi-lingual after-sales staff provide 24/7 support for overseas clients. Complete solutions for urgent issues are issued within 48 hours, and detailed replies to routine inquiries are provided within 72 hours, reducing after-sales losses for agents.
