Industry Pain Points & Requirements
Welding of vehicle bodies and components suffers high-temperature oxidation, slag inclusions and pores, leading to insufficient strength, rust issues and high rework rates.
Solution: Air separation equipment delivers effective anti-oxidation protection during welding and thermal processing, retaining structural strength and raising yield rate.

Battery cells are highly sensitive to moisture and oxygen. Exposure causes oxidation, bulging and even explosion. Dry rooms require humidity below 1% and oxygen content below 2%. Purchased liquid nitrogen comes with high costs and unstable supply.
Solution: Air separation systems support air circulation in dry rooms, provide protection for cell sealing and electrolyte filling, and prevent oxidation during electrode drying.

Oil and moisture in compressed air result in paint craters, pinholes and orange peel texture, causing frequent rework and extra costs.
Solution: Nitrogen is applied for protection during painting and drying processes to avoid discoloration from high-temperature oxidation.

Moisture and oxygen in regular air accelerate tire aging, causing unstable pressure, blowout risks and higher fuel consumption.
Solution: Nitrogen inflation via air separation equipment prevents oxidation and air leakage, eliminates blowout hazards. It extends tire service life by 20%–30% and cuts fuel consumption by 3%–5%.

High-temperature heat treatment leads to oxidation and decarburization of parts, along with uneven hardness and deformation that result in scrapped products.
Solution: Air separation equipment prevents oxidation and decarburization, ensuring uniform hardness and less deformation. The product yield reaches over 99%. Ideal for mass production of gears, shafts, springs and chassis parts.

The automotive industry including new energy vehicles relies on air separation equipment. High-purity nitrogen, oxygen and argon with controllable quality address six core demands: welding protection, lithium battery manufacturing, painting, heat treatment, tire safety and exhaust treatment. It cuts overall costs, ensures production safety and fits the industry’s shift toward new energy, acting as an essential industrial gas solution for vehicle and component manufacturers.
