Diverse handle structure materials, and ultrasonic welding builds a solid foundation for durability.

1. The types of luggage handles are rich and diverse. In terms of structural forms, the common ones include telescopic handles. This kind of handle is usually retractable, allowing users to adjust the height according to their own needs. Whether walking quickly with a luggage at the airport or pushing it in a narrow aisle, it can be easily dealt with. There are also fixed handles, which are stable and durable, and are often used on small luggage or backpack - style luggage, facilitating users to carry. From the perspective of materials, plastic handles are favored by many manufacturers due to their light weight, low cost, rich colors, and easy processing. Metal handles are known for their high strength and wear resistance, and often appear on high - end luggage, adding a sense of texture and durability to the luggage. In addition, there are rubber handles, whose soft touch brings a comfortable gripping experience and also has good anti - slip performance.

2. When the components of the luggage handle need to be connected and fixed, ultrasonic welding technology shows unique advantages. The heat generated by high - frequency vibration causes the handle components made of materials such as plastic to quickly melt on the contact surface. After cooling, a firm welded joint is formed, which can withstand large tensile and pressure forces, ensuring that the handle will not fall off or be damaged easily during use.
