GAM Gas-Assisted Injection Molding: Energy Saving, Carbon Reduction, Lightweight Design, Sustainability, Performance, Technology, and Green Competitiveness.
Why Choose Gas-Assisted Molding?
Gas-assisted molding technology, developed in the early 1980s, has revolutionized the design and manufacturing of many plastic molded products. Today, this process has become an important part of the global injection molding industry.
The technology is widely used in industries such as automotive, telecommunications, computers, home appliances, and material handling. It provides designers with greater flexibility in product design, allows manufacturers to reduce investment costs, and offers better control over the quality of finished parts. Most importantly, it delivers significant cost savings for end users.

Cost savings of over 20%
Introduction to Gas-Assisted Injection Molding Structure

High-pressure nitrogen is delivered through the gas-assisted main controller and injected directly into the molten plastic within the mold cavity. This causes internal expansion to form a hollow structure while maintaining the product’s surface integrity and overall shape intact.
Advantages of Gas-Assisted Injection Molding Systems
Integrated Design of Gas-Assisted Equipment
A multifunctional gas-assisted molding integrated system that combines a nitrogen generator, nitrogen booster, nitrogen storage cylinder, and pressure monitoring components. This design reduces pipeline connections between equipment, improves operational stability and efficiency, and effectively saves valuable factory space.
Product Lightweighting Over 20% & Cycle Time Reduced by More Than 20%
Material usage is reduced, lowering production costs. In general, product weight can be reduced by 10–30%. With savings in raw material costs and improved production efficiency, overall manufacturing costs can be reduced by more than 20%.
Eliminates Sink Marks on Finished Products
Improves surface quality while reducing residual stress and deformation. This lowers production costs, enhances product quality and manufacturing efficiency, strengthens structural integrity, and improves appearance by preventing warpage and sink marks.
Reduced Clamping Force
By lowering the internal pressure within the mold cavity, the required clamping force is reduced, which helps decrease overall production costs.
Modular Mechanical Design
Customized according to customer requirements, supporting flexible production and ideal for low-volume, high-mix manufacturing.
Suitable for Injection-Molded Thermoplastics
Compatible with thermoplastics used in injection molding (reinforced or non-reinforced), as well as general engineering plastics such as PS, HIPS, PP, ABS, POM, PBT, and PES, all of which can be applied in gas-assisted injection molding systems.
Smart Color Touchscreen Control System
Equipped with an intelligent color touchscreen interface to monitor the injection molding process, displaying preset and actual gas injection pressure and time, as well as molding and pressure-boosting operations.
The system provides real-time monitoring and allows configuration of five-stage pressure and time control, enabling precise settings for pressure increase rate, holding pressure time, and pressure levels. It also monitors the pressure and time curves inside the mold cavity.
