Modern Rattan-Weave Armless Gas-Assisted Chair Mold — Product Introduction (Motek Furniture Mold Series)

Product Positioning

Motek introduces dedicated injection molds for modern-style armless gas-assisted one-piece chairs with rattan-weave appearance. This product combines three features in one: rattan-weave texture provides natural aesthetics, the armless design meets stacking and compact placement requirements, and gas-assisted molding achieves a balance between lightweighting and high strength through hollow tubular structures. Suitable for restaurants, courtyards, and modern minimalist indoor/outdoor universal scenarios. The core challenges in mold development lie in coordinated design of rattan-weave textures and gas-assisted channels, gas penetration control under the armless open structure, and prevention of gas-assisted defects in textured appearance areas. Motek configures dedicated solutions around gas-assisted simulation, texture etching, and demolding mechanisms, helping customers achieve stable mass production of this composite chair model.

Core Specifications

Product Features

Coordinated Layout of Rattan-Weave Textures and Gas-Assisted Channels.

Rattan-weave appearance requires continuous, three-dimensional textures, while gas-assisted technology requires gas channels at thick-wall nodes such as leg-to-seat connections. Motek simulates nitrogen penetration paths through mold flow analysis (MoldFlow gas-assisted module), aligning gas channel routing with the chair’s load-bearing tubular structures while avoiding the deep grooves of rattan-weave textures, preventing gas from breaking through weak texture areas and causing “blow-through” defects on appearance surfaces. Gas channel corners use gradual cross-section transitions and larger fillets to avoid forming loops that cause gas stagnation.

Gas Penetration Control for Armless Open Structures.

Armless chairs lack the gripping structures of armrests or backrests, with the seat forming an open ring. The gas penetration path from injection port to overflow outlet needs to be re-planned. Motek positions gas injection needle valves in non-appearance areas such as seat undersides or inner leg surfaces, maintaining sufficient distance from the gate, and stabilizes the gas front position by adjusting short-shot size and gas delay time. Industry experience shows that gas nozzles should be placed at areas farthest from the last filling point with larger wall thickness; for armless chairs, the seat center and leg connection areas are ideal gas injection nodes.

Gas-Assisted Defect Prevention in Textured Areas.

Deep grooves and intersection nodes of rattan-weave textures are high-incidence areas for trapped gas and gas escape. Motek provides micro venting inserts at positions corresponding to texture dead corners, combined with gas-assisted overflow control, preventing nitrogen from remaining in texture grooves and causing surface bulging or silver streaks. Additionally, cavity surfaces require extremely high finish to compensate for the insufficient holding pressure of the gas-assisted process—industry practice is to polish appearance surfaces to A1 grade (Ra ≤0.025μm), achieving dense, smooth surfaces even without holding pressure assistance.

Appearance Surface Treatment for Modern Minimalist Style.

The armless design pursues visual simplicity, requiring pure, mark-free appearance surfaces. Motek positions parting lines at seat edges or undersides, with gate and gas injection needle valve positions all avoiding visual areas. Rattan-weave textured areas receive anti-scratch coating treatment, with sliders and inserts contacting textured surfaces requiring nitriding or surface hardening to ensure no texture damage during demolding. Non-textured areas can receive fine-texture or matte treatment, coordinating with the rattan texture.

Balancing Lightweighting and Structural Strength.

Gas-assisted technology achieves lightweighting through hollow tubular structures while maintaining sufficient bending stiffness. Motek strictly controls gas penetration depth and residual wall thickness, ensuring continuous and uniform hollow structures. Industry data shows that proper gas channel design can enable backrests to pass 4000N load-bearing tests with mass production yield exceeding 98%. For armless chairs, the seat-to-leg connection is a force concentration area requiring focused verification of gas penetration integrity and structural rigidity at that location.
