Chair injection mold with gas-assisted technology

Short Description:

Kaihua's Gas assistance chair molds integrate precision mold technology with practical design, achieving breakthroughs in furniture manufacturing. These advanced molds utilize gas assistance technology to precisely control gas injection molding, creating hollow structures during molding. This process significantly reduces product weight while dramatically improving material efficiency.
Gas-assisted injection molding technology offers significant advantages in mold production, not only reducing production costs but also decreasing product weight while shortening cycle time and improving appearance. The process begins with a short shot of molten plastic filling 60-95% of the mold cavity. High-pressure nitrogen gas is then injected to push the melt to completely fill the cavity while creating hollow sections. During the gas holding phase, continuous pressure ensures smooth surface finish and compensates for shrinkage. After cooling, the gas is vented and the part is ejected. This method is widely used to produce chair components like armrests and backrests, achieving lightweight designs without compromising structural integrity while significantly boosting production efficiency and cost-effectiveness.
Additionally, Kaihua mold possesses extensive expertise in manufacturing Outdoor leisure plastic chairs and Kid plastic chair, consistently delivering safe, durable, and internationally certified seating solutions to global clients. Choose Kaihua for guaranteed quality.

1.Product Introduction

he Kaihua gas assistance injection mold of chair adopt an intelligent production line to innovate the traditional manufacturing process. Workers only need to complete the clamping of iron materials and feeding of materials, while the rest of the processes such as feeding, processing, and unloading are all automatically completed by high-precision robots.
In addition, the interchangeable design of the molds is a major highlight. Through a modular structure, the production switch of chairs in different styles and sizes can be easily achieved to meet diverse market demands. With the advantages of lightweight, high efficiency, and high flexibility, the molds adopt the advanced gas-assisted injection molding technology. The created hollow chair frame has the dual advantages of being lightweight and high-strength. The modular design supports quick mold changing to meet diversified needs.
With the perfect combination of intelligent manufacturing and innovative craftsmanship, Kaihua provides customers with high-cost-effective and fast-delivery high-quality product solutions, helping customers gain a competitive edge in the market.
