Профессиональный высококачественный азотный генератор PSA производитель N2 газовое оборудование 23 года для пластиковой промышленности

Nitrogen is widely used in the plastics industry. Injection molding, film extrusion, and gas-assist injection molding all use nitrogen because of its inertness and dryness. CANGAS On-site nitrogen is an ideal choice, as nitrogen can be generated on demand without relying on deliveries from a third party supplier. 

In injection molding, moisture and oxygen can cause issues with the final product including defects and blemishes. Using dry nitrogen generated from a CANGAS on-site nitrogen generator eliminates these complications.

Gas assist injection molding (GIAM) involves a multi-step molding process. It is a way to make thick plastic parts without issues created from excess shrinkage of the part. It is a type of injection molding that uses inert gas to create a very dense and strong plastic part that uses nitrogen to pack out the part and compensate for shrinkage. First, the polymer is injected into a mold though not all filled. Nitrogen under high pressure is injected into the polymer, pushing it into areas of the mold that are not yet filled. The nitrogen pressure is maintained during the cooling phase of the molding process, and gas pressure is released and the part is ejected.

Film extrusion is achieved by extruding a molten thermoplastic using a screw through a die. Afterward, it is inflated to many times its initial diameter forming a thin tubular film. Screw carbonization and frequent die cleaning, caused by oxygen in the feed throat hopper, are issues with blown film extrusion that can be improved or eliminated by using a nitrogen purge

What Is Nitrogen Gas Purity?
Nitrogen gas purity refers to the proportion of a nitrogen gas that is present in a sample taken from its stream when compared to impurities present. Nitrogen gas can be categorized as high purity or low purity depending on the ratio of pure gas to the contaminants like oxygen, water vapor, carbon monoxide, and carbon dioxide.

This categorization based on nitrogen concentration plays a key role in determining the suitability of nitrogen to any industrial process.
