Plastic Injection Molding
Gas Assist Injection Molding Service
Gas assist Injection molding is a low-pressure plastic injection molding process where pressurized nitrogen gas is injected into the mold, pushing the plastic into the mold extremities, while hollowing out thicker sections in the part.In the gas assist molding process, the plastic material is melted and injected into the mold cavities via the conventional plastic injection molding process. Plastic material in contact with the mold walls begins to solidify first. As this happens, nitrogen gas is injected into the mold through strategically designed and placed gas channels, providing the pressure that pushes the plastic material into the mold extremities. Once the plastic cures, the nitrogen is vented and the parts are removed from the mold.

Gas Assit Injection Molding Tooling Design&Making
If you want to achieve high quality parts, ensure you get the mold design, manufacturing and moldflow right. it is as critical to a successful part launch as the rest of the part design process. Tooling cost, timeline and resulting part quality will be directly impacted by the quality and efficacy of the tool.We use the latest UG technology and software to create a robust mold design that’s built to SPI standards, as well as moldflow analysis to evaluate all mold designs and parts prior to development. Mold flow analysis is used to find design constraints so that adjustments can be made, where the gate, hot runner or cold runner is... and the pressure of nitrogen.
the tool will be designed with gas channels built in to the mold that will allow the addition of nitrogen gas during the molding process. Determining your molding method early will conserve tooling cost and help to maintain project timelines. it is a integral part of mold design.
Gas Assist Injection Molding Process
From a product design perspective, gas assist allows engineers to create larger, thicker, and more complex moldable and no shrinkage parts that would not be possible using traditional methods.A few design considerations need to be taken for gas assist molded parts when designing for manufacturing. The part design must be adapted to include features that control where, when, and how gas is introduced on the plastic surfaces. There needs to be gas zones and modified thicknesses in areas where the gas is applied to the part. gas assist requires design modifications that add overspill pins and gas pins. Overspill pins help to remove any extra resin and gas pins are where the gas is inserted. Specialized gas control equipment must be programmed to insert the gas at the correct timing and pressure during the molding process. Acting from within the component shape, the gas inflates the component and counteracts the effects of the material shrinkage. The effect is to keep an internal pressure on the material until it solidifies and skins at the mold cavity surface.
Advantages of Gas Assist Injection Molding
Gas Assisted Injection Moulding (GAIM) is a relatively new technology in plastics injection moulding that offers opportunities to reduce moulding costs, improve quality and allows designers to be even more imaginative and freedom in the creation of injection moulded components.
● Saving Material
● Reduced Part Weight
● Reduced Cost
● Decreased Cycle Time
● Increased Part Strength and Rigidity
● Reduced Warpage and Distortion
● Improved Part Appearance
● Improved Design Freedom
Applications
Gas assisted moulding involves the introduction of nitrogen under pressure to the mould cavity at a set time during the moulding cycle. The aim is to either hollow out thick section mouldings or eliminate sinkage and/or warpage in thin section injection mouldings. Gas injection can also result in stronger parts due to the ‘box section’ effect.
