plastic furniture Gas-assisted injection molding

Gas-assisted injection molding is a novel plastic molding technology that introduces high-pressure gas into the thick-walled parts of the parts, creates hollow sections inside the injection-molded parts, completely fills the process, achieves gas pressure retention, and eliminates sink marks on the products. The traditional injection molding process cannot form the thick wall and the thin wall together, and the residual stress of the part is large, easy to warp and deform, and the surface has a sink mark. The newly developed gas-assisted technology succeeds in producing thick-walled and partial-wall products by hollowing out the thick-walled interior, and the products have excellent surface appearance and low internal stress. Lightweight and strong. Has been successfully developed gas-assisted product structure and mold design including gating system, air intake and air distribution design technology, gas-assisted injection molding process design technology, gas-assisted injection molding process design technology, gas-assisted injection molding process computer simulation technology, gas-assisted injection molding products Defects diagnosis and elimination technology, gas auxiliary technology special material technology.


TVs, home appliances, automobiles, furniture, daily necessities, office supplies, toys, etc. open up entirely new fields of application for plastic molding. Gas-assisted injection molding technology is particularly suitable for pipe-shaped products, thick-walled, offset walls Parts) and large flat structure parts.

Gas Aids: Includes nitrogen generation and booster systems, pressure control units, and air intake elements. The investment is about 40--200 million yuan (depending on the scale and equipment requirements of the different grades). The gas-assisted process can be fully integrated with the traditional injection molding process (injection molding machine).

Reducing the weight of the product (saving material) can be 40% higher, shortening the molding cycle (up to 30% saving time, eliminating sink marks, and improving the yield; reducing the injection pressure by 60%, using small-tonnage injection molding machines to produce large parts, reducing operating costs The mold life is prolonged and the manufacturing cost is reduced, and more stable structures such as thick roots, thick ribs, connecting plates, etc. can be used to increase the degree of freedom in design of the mold, and usually the equipment cost can be recovered in 6 to 18 months (specific economic benefits).
