  1. Nitrogen Applications in the Plastic Manufacturing Industry Nitrogen is widely used in the plastics industry. Injection moulding, film extrusion, and gas assist injection mouldingprocesses all use nitrogen because of its inertness and dryness. On site nitrogen is an ideal choice, as nitrogen can be generated on demand without relying on deliveries from a third party supplier. Nitrogen generators and nitrogen plants are a common sights on plastic manufacturing facility, particularly the large ones, as they are cost- effective and save time. Plastic manufacturers and nitrogen gas plant manufacturers in India have a god working relationship as a result of this. In injection moulding, moisture and oxygen can cause issues with the final product including defects and blemishes. Using dry nitrogen generated from an on-site nitrogen generator eliminates these complications. Gas assist injection mouldingor GIAM involves a multi-step moulding 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 moulding that uses an 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 mould though not all filled. Nitrogen under high pressure is injected into the polymer, pushing it into areas of the mould that are not yet filled. The nitrogen pressure is maintained during the cooling phase of the moulding 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.
