Gas Assist | |
|
With the gas injection process, complex single moldings combining thick and thin walls, hollow sections, and elongated shapes can now replace assemblies requiring several or many parts. This technology affords our customers greater freedom for design. The process also gives us several advantages in production which include Reduced Material Stress, Reduced Weight, and Smoother Surface Appearance. |

Reduced weight: With the injection of an inert gas, such as nitrogen, the gas displaces the resin in the thicker sections of the molded product. This results in hollow sections and consequently less weight. A related benefit is a higher stiffness-to-weight ratio. Smoother Surface Appearance: Since gas cores out the plastic instead of mixing with it, typical injection mold problems are eliminated, resulting in a smooth surface finish. The decrease of material in each part also decreases the amount of time needed for that part to cool. Reduced Stress: The low pressure inside the mold cavity not only reduces the degree of frozen-in stress and the tendency to warp, it also permits the production of moldings under much lower clamp forces ( up to 50% lower). |
