In two-color injection molding, if the runner design is not reasonable, such as a single gate causing color gaps at the far end or inconsistent flow rates at multiple gates, it can easily lead to color layering or uneven mixing.

A protective layer can be formed at the joint by spraying or dipping processes, which can enhance wear resistance and anti-aging properties and extend the service life of the product.

In the production process of silicone two-color straps, precise control of the vulcanization time is the core element to ensure the strength of the two-color bond.

Optimizing the bonding process between the texture and the substrate (such as using chemical bonding instead of physical bonding) can prevent the texture from peeling off after long-term use.

The production workshop needs to maintain constant temperature and humidity conditions to avoid temperature fluctuations that could cause changes in material shrinkage or thermal expansion and contraction of molds.

In today's world where outdoor enthusiasts increasingly seek lightweight and multifunctional gear, the composite material strap designed specifically for the Garmin Fenix ​​series—with a silicone base and a leather or nylon outer layer—has become a popula
