Gas Assist Molding
Gas Assisted Molding Service
Gas assisted injection molding is a process which inert gas (usually is nitrogen) is used to push and displace unfrozen plastic material to hollow out plastic parts. In the gas assist injection molding process, the plastic material is melted and injected into the mold cavities via the conventional plastic injection molding process. Then the nitrogen gas is injected directly into the component's cavity, pushing the unfrozen plastic into the mold extremities, while hollowing out thicker sections in the part.
Innovative Gas Assist Injection Molding Solutions
From a product design perspective, gas assist injection molding allows engineers to create larger, thicker, and more complex moldable and no shrinkage plastic 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.
■ Avoid Sharp Corner
■ Considering Gas Entry and Exit Locations
■ Design for Manufacturability
■ Engineering Support
■ Material Selection Suggestion

Thick Wall Plastic Parts Saviour--Gas Assisted Injection Molding
Gas assist injection molding is displacing molten plastic from thicker sections of the part toward areas in the cavity that are last to fill, nitrogen gas pressure creates channels within the part. Through the gas channels, pressure is transmitted evenly across the part, eliminating warpage, sink marks, internal stress and increased the strength and rigidity. This process can be implemented thick wall and complex products:
■ Smooth Surface
■ Minimizes Manufactring Defects
■ Improved Dimensional Quality
■ No Sink Mark
■ Light Weight Porducts
■ No warppage
Premium Gas Assisted Injection Molding Tooling Design & Making
If you want to achieve quality parts, ensure you get the mold design, making and Moldflow right. Tooling cost, timeline and resulting part quality will be directly impacted by the quality and efficacy of the tooling.
It is important to engage your molder during the early stages of part design in the design for manufacturing (DFM) phase.
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.
When the mold engineer determines gas assist is the best solution, the mold 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. Getting your molder involved early will be critical to a cost effective, high-quality product.

Advantages of Gas Assisted Injection Molding
Gas Assisted Injection Molding (GAIM) is a relatively new technology in plastic injection molding that offer opportunities to reduce molding cost, improve quality and allow designer to be even more imaginative and freedom in the creation of injection molding parts. the benefits including:
● 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 of Gas Assisted Injection Molding
Gas assisted injection molding involves the introduction of nitrogen under pressure to the mold cavity at a set time during the molding cycle. The aim is to either hollow out thick section moldings and eliminate shrinkage and warpage in thin section injection molding. Gas assist injection molding can result in stronger plastic parts due to the ‘box section’ effect. This process have a wide indudtry application, including:
● Appliance Handles
● Steering Wheel
● Automotive Handles
● Treadmill Support
● Canopy Base
● Children Car Frame
● Children Safe Chair Backboard
● Coat Hanger
● Tool Box
● And More
