Duo alloy slider series (DAS) 双合金拉头系列 (DAS)

使用不锈钢零部件来增强扭矩力的拉头：包括不模盖，马钩和弹簧。

This design can greatly reduce the   cost and increase the simplicity, and can save the investment in new molds.

这种设计可以大大降低成本，增加简单性，并可以节省新模具的投资。

这种变化只是弥补了单一材料的扭矩限制。如果原色是不锈钢银色，它可以持续很长时间，永远不会生锈！

This change just makes up for the   torque limit of a single material. If the primary color is stainless steel   silver, it can last for a long time and never rusty!

Such a design can make outdoor and   water activities more optional

这样的设计可以让户外和水上活动多一种选择
