Main application of gas-assisted molding technology
Gas-assisted molding has a particularly obvious effect on the material saving of tubular and rod-shaped plastic parts, such as car handles, seat armrests, window frames, and wood-like furniture, the material saving rate of this kind of parts can be reached in 20%-40%. For large flat parts, such as door panels, refrigerator trays, automotive interior and exterior parts, gas-assisted reinforcing ribs can be used to eliminate the warping deformation of the flat parts due to residual stress and improve the strength of the parts. Home appliances are the largest application field of gas-assisted technology., for large-screen color TVs and TV brackets over 64cm, more than 90% of them use gas-assisted molding technology, with the increasing market demand for large-screen color TVs and cars, and the popularization of home computers, gas-assisted molding technology will obtain immeasurable economic benefits in the application of household appliances. From the perspective of the trend of replacing steel with plastic, the automobile, furniture, construction, and instrumentation industries will also compete to use gas-assisted molding technology in order to save materials, improve product quality, and participate in the competition in the international market. The promotion and application of gas-assisted molding technology has pushed the plastics processing industry to a new stage of development.
