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.
In principle, this kind of welding mesh, in the horizontal wire and vertical wire overlap parts, spraying powder is not able to completely cover, so there will be water entering this part when it is wet or raining, causing rust;
If there is galvanized layer protection, there will be no such problem, galvanized than spray zinc rich powder cost is higher, we choose a high cost process, is to solve the problem of rust.
The whole welding and polishing finish galvanized, no dead Angle formed galvanized protective layer; Then spray high-quality outdoor electrostatic polyester powder, double rust prevention, long-term use without rust.
If the frame is not galvanized, there is no anti-rust measure, which leads to local modification easily, and the service life is greatly affected.
