Plastic Full-Rattan Single-Seat Sofa Mold — Product Introduction (Motek Furniture Mold Series)
Plastic Full-Rattan Single-Seat Sofa Mold — Product Introduction (Motek Furniture Mold Series)
Product Positioning
Motek introduces dedicated injection molds for full rattan-weave appearance single-seat plastic sofas used in restaurants, courtyards, and leisure settings. Full-rattan single-seat sofas use injection molded components to fully replicate rattan-weave textures, with the seat, backrest, and side panels all capable of presenting continuous rattan effects—combining natural aesthetics with the durability and easy-clean properties of plastic products. The core challenges in mold development lie in precise replication of full rattan-weave textures with demolding scratch protection, core-pulling demolding mechanism design for the hollow cavity structure of single-seat sofas, and load-bearing and weather resistance assurance under high-frequency outdoor use. Motek configures dedicated solutions around texture etching processes, curved core-pulling systems, and material selection, helping customers achieve stable mass production of full-rattan single-seat sofas.

Product Features
Precise Replication of Full Rattan-Weave Textures with Demolding Scratch Protection.
The visual core of full-rattan sofas lies in the three-dimensionality and continuity of the texture. Motek uses EDM etching processes to reproduce the warp-and-weft interweaving and relief layers of the weave on cavity surfaces. S136 or 1.2316 corrosion-resistant steels are selected for textured areas to ensure clear details and long-term rust-free service. Imitation rattan textures are highly susceptible to scraping by mold walls during demolding. The mature industry approach is to apply nitriding or surface hardening treatment with anti-scratch coatings to moving components such as sliders and inserts, ensuring smooth movement without damaging the texture.
Curved Core-Pulling Mechanism Design for Hollow Cavity Structures.
To reduce weight and meet structural requirements, full-rattan single-seat sofas often require hollow cavities formed inside the seat and backrest. Referencing mature industry solutions, Motek arranges curved core-pulling plates symmetrically on the left and right sides of the forming cavity, with an additional curved core-pulling plate at the rear. Through a curved synchronized core-pulling mechanism, a single driver achieves synchronized core-pulling of both side plates, reducing cost while ensuring cavity forming accuracy. Core-pulling and ejection timing are designed with linkage, ensuring ejection is performed only after the product is released from constraints.
Structural Reinforcement for High-Frequency Use Scenarios.
Restaurant and outdoor settings place high demands on sofa load-bearing capacity and durability. Motek optimizes wall thickness transitions and reinforcement rib layout at load-bearing areas of the seat, and at the connection between the backrest and base, 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, PE rattan compounds or PP+GF reinforced compounds can be selected to enhance load-bearing capacity while maintaining rattan texture quality.
Outdoor Weathering-Oriented Steel and Surface Treatment.
Outdoor full-rattan sofas are exposed long-term to UV and temperature fluctuations. S136 or 1.2316 with good corrosion resistance is recommended for cavity steel; industry experience shows such stainless steels can achieve service life exceeding 1,000,000 shots with proper maintenance. Polishing treatment in textured areas balances demolding smoothness and texture clarity. 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.
Balanced Ejection to Protect Texture Appearance.
Single-seat sofas are relatively large with textured surfaces, and uneven ejection force can cause stress whitening or texture indentation. Motek adopts a multi-point balanced ejector pin or ejector block layout, with ejection points preferentially located in non-textured areas (such as base connection points and sofa undersides), ensuring no visible ejector marks on the appearance surface during demolding.
Applications
Motek plastic full-rattan single-seat sofa molds are suitable for:
- Restaurant/cafe full rattan-weave single-seat sofas
- Courtyard/terrace imitation rattan single-seat sofa chairs
- Outdoor leisure rattan-weave sofas (with backrest and side panels)
- Commercial food service rattan-weave sofa seats
- Imitation rattan texture single leisure chairs (all-plastic structure)
Service Process
After the customer provides 3D product drawings and rattan texture samples or reference images, Motek completes texture etching plan confirmation, mold flow analysis (including textured area filling evaluation and hollow cavity core-pulling plans), 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 texture appearance confirmation, core-pulling mechanism operation testing, and load-bearing verification, 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 rattan-weave chairs to full-rattan single-seat sofas, providing reliable mold solutions for injection-molded texture forming and hollow cavity core-pulling of restaurant and outdoor furniture.
