Gas-Assisted Injection Molding (GAIM)
The principle of gas-assisted injection molding lies in the utilization of high-pressure gas injected into the mold cavity while the plastic melt is still partially molten. During the injection molding process, molten plastic is first injected into the mold cavity. Subsequently, before the plastic has fully solidified, high-pressure gas is introduced into the cavity. This high-pressure gas pushes the plastic towards the mold walls, forming thin-walled structures.
Compared to traditional injection molding methods, GAIM offers several advantages:
Reduced Raw Material Consumption: GAIM enables less plastic material, lowering production costs. Typically, GAIM can save 20%-50% of raw materials.
Enhanced Product Quality: GAIM promotes uniform product wall thickness, minimizing warpage and deformation caused by shrinkage, and improving product dimensional stability and surface quality.
Shortened Production Cycle: GAIM facilitates faster product filling and shorter cooling times, leading to a reduced production cycle.
Lower Clamping Force: GAIM diminishes internal product pressure, lowering clamping force requirements and easing the burden on the injection molding machine.
