Advantages of hot melt drilling vs. Riveting：

Enhanced Connection Strength:

Hot melt drilling  penetrates metal materials using high temperature and high rotational speed, forming a thickened sleeve-like structure around the hole. This ensures a more secure threaded connection, as hot melt drilling  creates a thicker connection wall, increasing thread load capacity.

Superior Sealing and Anti-Loosening Performance:

The metal sleeve formed by hot melt drilling is tighter, less prone to loosening, and reduces gaps, improving waterproofing and dust resistance. In contrast, riveted connections may have gaps, compromising sealing performance.

Neater Appearance:

Hot melt drilling  does not leave visible connection points on the material surface, resulting in a cleaner overall finish. Note: The use of riveting is strictly prohibited in sports equipment.

Disadvantages of Riveting:

Riveted connections lack sufficient strength, often have gaps that impair sealing, and are prone to loosening and detachment.
