Maximize Plastic Part Quality with Gas Assisted Injection Molding Technology
Introduction
In today’s world, plastic parts are ubiquitous and can be found in a variety of applications, ranging from medical devices to consumer electronics. However, manufacturing high-quality plastic parts is not an easy task. To achieve the highest possible quality, manufacturers must use advanced technologies and processes, such as gas assisted injection molding (GAIM).
Gas assisted injection molding (GAIM) is a relatively new process that is being used in the manufacture of plastic parts. The process involves injecting a gas, such as nitrogen or carbon dioxide, into a plastic part while it is still in the mold. This creates a hollow core in the part, which reduces warpage and shrinkage, improves part quality, and reduces cycle times and part weight.
What is Gas Assisted Injection Molding Technology?
Gas assisted injection molding (GAIM) is a process used to produce high-quality plastic parts with improved structural characteristics. During the process, a gas, such as nitrogen or carbon dioxide, is injected into the molten plastic while it is still in the mold. This gas forms a hollow core in the part, which reduces warpage and shrinkage, improves part quality, and reduces cycle times and part weight.
GAIM is a relatively new technology that has been developed to meet the demands of today’s plastic part manufacturers. It is becoming increasingly popular due to its ability to produce complex parts with improved surface finishes and structural characteristics. The process is also highly efficient and cost-effective.
Benefits of Gas Assisted Injection Molding Technology for Plastic Parts
Gas assisted injection molding offers a number of benefits for plastic part manufacturers. These include reduced warpage and shrinkage, improved part quality, reduced cycle times, reduced part weight, and cost savings.
Reduced Warpage and Shrinkage
Gas assisted injection molding technology helps reduce warpage and shrinkage in plastic parts by forming a hollow core in the part. This hollow core helps to reduce the amount of stress on the part and prevents it from warping or shrinking during the cooling process.
Improved Part Quality
Using GAIM technology also helps to improve the overall quality of plastic parts. The hollow core reduces the amount of stress on the part, resulting in improved surface finish and structural integrity. Additionally, the process is highly efficient and cost-effective, allowing manufacturers to produce high-quality parts in a shorter amount of time.
Reduced Cycle Times
Gas assisted injection molding also helps to reduce cycle times. By forming a hollow core in the part, the cooling process is sped up, resulting in shorter cycle times and faster production.
Reduced Part Weight
GAIM technology also helps to reduce the weight of plastic parts. The hollow core in the part reduces the amount of material needed to produce the part, resulting in lighter parts that are more cost-effective to produce.
Cost Savings
Finally, gas assisted injection molding technology helps to reduce costs for plastic part manufacturers. The process is highly efficient and cost-effective, resulting in lower production costs and increased profits for manufacturers.
Gas Assisted Injection Molding Process
The gas assisted injection molding process is relatively simple and involves a few steps. Here is an overview of the process:
The Basics of Gas Assisted Injection Molding
Gas assisted injection molding is a process whereby a gas, such as nitrogen or carbon dioxide, is injected into the molten plastic while it is still in the mold. This gas forms a hollow core in the part, which reduces warpage and shrinkage, improves part quality, and reduces cycle times and part weight.
Steps in the Gas Assisted Injection Molding Process
The steps in the gas assisted injection molding process are as follows:
- First, the mold is filled with molten plastic.
- Then, the gas is injected into the mold.
- The gas fills the hollow core of the part, reducing warpage and shrinkage.
- The part is then cooled and removed from the mold.
- Finally, the part is finished and ready for use.
Types of Gas Assisted Injection Molding
There are two main types of gas assisted injection molding: direct gas injection molding and indirect gas injection molding.
Direct Gas Injection Molding
Direct gas injection molding is the most common type of gas assisted injection molding. In this process, the gas is injected directly into the mold cavity at high pressure. This process is used to produce parts with complex geometries and thin walls.
Indirect Gas Injection Molding
Indirect gas injection molding is a less common process, but is sometimes used for producing parts with thicker walls. In this process, the gas is injected into the mold through a secondary injection port. This process is slower than direct gas injection molding, but produces parts with higher quality and less warpage.
Advantages of Gas Assisted Injection Molding Technology
Gas assisted injection molding technology offers a number of advantages, including reduced warpage and shrinkage, improved part quality, reduced cycle times, reduced part weight, and cost savings.

The hollow core reduces the amount of stress on the part, resulting in improved surface finish and structural integrity.

Conclusion
Gas assisted injection molding is an advanced technology that offers a number of advantages for plastic part manufacturers. The process helps to reduce warpage and shrinkage, improve part quality, reduce cycle times, reduce part weight, and reduce costs. For these reasons, gas assisted injection molding is becoming increasingly popular in the plastics industry.
