In the contemporary trendy toy industry, blind box dolls represented by Bubble Mart have become the new favorite of the global consumer market due to their excellent manufacturing technology and unique collection experience. The core of the manufacturing quality of such products largely depends on the precise application of the plastic connection technology - ultrasonic welding process.

Ultrasonic welding of toy dolls with high-frequency mechanical vibration generates frictional heat and instantaneous melting of plastic contact surface molecules, achieving molecular level fusion under preset pressure. Compared to traditional connection techniques, it has the following significant features:

1. Non contact heat source, connected only through mechanical vibration

2. No need for any auxiliary connecting materials

3. Accurate control of energy output and action time

Five technological advantages of welding blind box dolls

1、 Surface integrity guarantee

• Achieve micron level welding accuracy, with weld width controlled within 0.1mm

Completely avoid common problems such as glue overflow and discoloration in the bonding process

• Maintain the integration of product design surfaces to meet the aesthetic requirements of collectible toys

2、 Production efficiency optimization

• Single piece welding cycle shortened to within 0.5-2 seconds

• Support automated assembly line integration, significantly improving Nissan production

The yield rate remains stable at over 99.8%

3、 Structural reliability performance

Welding strength reaches 85% -95% of the base metal

• Significant improvement in drop resistance performance

4、 Comprehensive cost advantage

Ultrasonic welding reduces the cost of individual toy dolls

• Energy consumption is only one-third of that of hot plate welding

Reduce post-processing steps
