Plastic Handle Gas Injection Mould

Gas-assisted molding refers to the injection of high-pressure inert gas when the plastic is filled into the cavity (90%~99%), the gas pushes the molten plastic to continue to fill the cavity, and uses gas pressure to replace the plastic pressure holding Emerging injection molding technology. This article will introduce the principles and processes of gas-assisted injection molding.



(1) When designing, first consider which wall thickness needs to be hollowed out and which surface sink marks need to be eliminated, and then consider how to connect these parts to become an airway.
(2) Large structural parts: fully thinned and partially thickened into airways.
(3) The air passage should be evenly arranged on the entire mold cavity in accordance with the main material flow direction, and at the same time, the closed circuit air passage should be avoided.
(4) The cross-sectional shape of the air channel should be close to a circle to make the gas flow smoothly; the cross-sectional size of the air channel should be appropriate. If the air channel is too small, it may cause gas penetration.
(5) The airway should extend to the final filling area (generally on the non-appearance surface), but need not extend to the edge of the cavity.


(6) The main airway should be as simple as possible, the branch airways should be as long as possible, and the end of the bronchial airway can be gradually reduced to prevent the gas from accelerating.
(7) The airway can be straight without bending (the less bending, the better), and the corner of the airway should use a larger radius.
(8) For multi-cavity molds, each cavity needs to be supplied by an independent air nozzle.
(9) If possible, there is a second option for not allowing gas to advance.
(10) The gas should be confined to the airway and penetrate to the end of the airway.
