Plastic Rattan-Weave Steel-Tube Chair Mold — Product Introduction (Motek Furniture Mold Series · Restaurant & Outdoor Furniture)
Plastic Rattan-Weave Steel-Tube Chair Mold — Product Introduction (Motek Furniture Mold Series · Restaurant & Outdoor Furniture)
Product Positioning
Motek introduces dedicated injection molds for plastic rattan-weave steel-tube chairs used in restaurant and outdoor settings. These products use steel tubes as the load-bearing frame and plastic rattan-weave components as the seating surface and backrest—combining the strength of metal structures with the natural aesthetic of rattan, suitable for high-frequency use environments such as restaurant patios, courtyards, and terraces. The core challenges in mold development lie in forming the connection structure between steel tubes and plastic components, precise replication of imitation rattan textures with demolding scratch protection, and structural strength assurance under high-frequency restaurant and outdoor use. Motek configures dedicated solutions around connection structure design, texture etching processes, and material selection, helping customers achieve stable mass production of rattan-weave steel-tube chairs.

Product Features
Integral Forming and Precision Control of Steel-Tube Connection Structures.
The steel tube frame and plastic rattan-weave components of rattan-weave steel-tube chairs are secured through insertion, snap-fits, or connectors. Motek forms steel tube insertion seats and connection bosses in the mold, with dedicated tolerance control on insertion hole diameter, depth, and locating features, ensuring smooth tube insertion and no loosening or wobbling after assembly. For hollow structures requiring secondary core-pulling, referencing industry steel-tube chair mold core-pulling ejection solutions, stepped demolding is adopted to ensure synchronous forming of hollow sections.
Precise Replication of Imitation Rattan Textures with Demolding Protection.
The quality of rattan-weave appearance depends on the three-dimensionality and continuity of the texture. Motek performs etching on cavity surfaces based on customer-provided rattan samples or texture drawings, reproducing the warp-and-weft interweaving and relief layers of the weave. The mature industry approach uses 0.2mm-depth textures combined with precise draft angles to prevent texture tearing during demolding. S136 or 1.2316 corrosion-resistant steels are selected for textured areas, and sliders and inserts contacting textured surfaces require nitriding or surface hardening treatment with anti-scratch coatings to ensure smooth movement without damaging the texture.
Structural Reinforcement for High-Frequency Restaurant and Outdoor Use.
Restaurant patios and courtyard settings place high demands on chair load-bearing capacity and durability. Motek optimizes wall thickness transitions and reinforcement rib layout at load-bearing areas of the seat and backrest to avoid stress concentration. Mold flow analysis is used to evaluate filling end positions in deep texture groove areas, with proper venting inserts arranged to prevent incomplete texture formation or weak points caused by trapped gas. For materials, PP+GF reinforced compounds can be selected to enhance load-bearing capacity while maintaining rattan texture quality.
Anti-Scratch Demolding Mechanism Design.
Imitation rattan textures are highly susceptible to scraping by mold walls during demolding—a recognized industry challenge. Motek provides ample draft angles in textured areas, with a balanced ejection system layout and ejector pin locations preferentially set in non-textured areas (such as connection bosses and undersides). For complex structures with undercuts, a slider and ejection linkage solution is adopted: during mold opening, sliders and inserts are first moved away to release constraints, then ejection is performed, preventing product damage.
Outdoor Weathering-Oriented Material and Surface Treatment.
Outdoor rattan-weave chairs are exposed long-term to UV and temperature fluctuations. During the mold design phase, the UV resistance grade of the plastic base material must be confirmed with the customer, and shrinkage rate differences of modified materials must be considered in cavity dimension calculations. Non-textured areas can receive fine-texture or matte treatment as required to enhance surface wear resistance and scratch resistance while maintaining texture coordination with textured areas.
Applications
Motek plastic rattan-weave steel-tube chair molds are suitable for:
- Restaurant patio rattan-weave steel-tube chair seats/backrests
- Courtyard/terrace imitation rattan steel-tube chairs
- Outdoor leisure rattan-weave armchairs
- Stackable rattan-weave steel-tube chairs (stacking structure evaluation required)
- Commercial food service rattan-weave chairs (seat + backrest assemblies)
Service Process
After the customer provides 3D product drawings, rattan texture samples or reference images, and steel tube connection plans, Motek completes texture etching plan confirmation, mold flow analysis (including textured area filling evaluation and connection structure dimension compensation), and mold structure design; cavity steel is selected per texture and weathering requirements, with texture samples provided for customer confirmation before etching; during trial molding, Motek cooperates with the customer on steel tube assembly verification, texture appearance confirmation, and demolding mechanism operation testing, providing samples for final sign-off. Before shipment, molds undergo anti-rust treatment and action testing, with water circuit diagrams, consumable parts lists, and texture maintenance notes provided. Technical support is available during the warranty period, with lifetime maintenance consultation.
Motek — From plastic tables to rattan-weave steel-tube chairs, providing reliable mold solutions for injection-molded texture forming and structural assembly of restaurant and outdoor furniture.
