Q1: What is the AF-2890Y Ultrasonic Spot Welding Machine?<\/span><\/span><\/strong><\/p>\n

A1: The AF-2890Y Ultrasonic Spot Welding Machine is a device that <\/span>uses ultrasonic technology to connect metal or non-metal materials<\/span><\/strong>. When the <\/span>welding head contacts the material to be welded<\/span><\/strong>, the <\/span>high-frequency vibration<\/span><\/strong> causes <\/span>intense friction<\/span><\/strong> between the molecules on the surface of the material, thereby generating heat, causing the material to <\/span>partially melt or reach a plastic state<\/span><\/strong>, and <\/span>welding is achieved under pressure<\/span><\/strong>. The machine can weld <\/span>most thermoplastics<\/span><\/strong> (except Teflon) and has a wide range of applications; the welding time is short, usually only <\/span>0.05\u20131 second<\/span><\/strong>; it can be welded to the joint surface through media such as <\/span>water, oil<\/span><\/strong>, etc.; the welding effect is good, and it can achieve <\/span>airtight, liquid-tight<\/span><\/strong> and other sealing effects; no need to add any adhesive, the operation is simple and safe. The machine is small, which is suitable for factories with limited space or that need to move the working position according to production needs.<\/span><\/p>\n<\/div>
