Gas Assist from the Experts at Sajar

The gas assisted process combines the best aspects of structural foam and straight injection.

Why Gas Assist?

Gas assist produces many efficiencies – the following are typical results:
30% part savings compared to Structural Foam
20% - 30% tool savings compared to Straight Injection

How does it work?

Gas assisted injection molding is a low pressure, conventional injection molding process that forces a short shot of material to fill a mold by using pressurized nitrogen gas to displace the material in pre-designed thick areas, while forming hollow sections in the part.

Looking for cost efficiencies?

Because of this ingenious process, the following can be achieved:
Use less material
Smaller press sizes can be used – reducing hourly rates
Shorter cycle times – fewer hours on the job
Molded-in surface texture – decreased need for costly finishing operations
 

Need design enhancements?

Cost savings are not the only benefits.
Typical cosmetic upgrades include:
Reduced warp
Thick sections (bosses) with no sink
Reduced part weight – larger parts are now possible
High cosmetic surfaces – allows for aesthetic design options
Increased dimensional stability–allows aesthetics to be enhanced without compromises
