Laser micromachining & Laser welding for polymers: shaping manufacturing and industries’ future(s).
UV nanosecond laser: Polymers find widespread applications and are also increasingly replacing other materials, such as metals. Polymers, in general, are suitable alternatives to various other substances due to their low density, chemical resistance, cost, and other traits. Custom polymer synthesis is also an emerging field that enables end-users and manufacturers to build polymer materials according to their requirements. Laser welding complements the properties of polymers, allowing the combination of polymer material weldments that are precise, clean, high quality, durable and long-lasting.
Welding in the Indian subcontinent is relatively adopted by various engineering, design, and construction/manufacturing companies. Plastics are widely utilised in healthcare, automotive, aerospace, and information technology products. As times change, the firms and production processes continuously search for improvements and alternatives.
