Sauna roomtemperature is much higher than the normal outdoor temperature, for this moment temperature changes will lead to the quartz watch in the early aging of the waterproof gasket.
桑拿房的温度远远高于室外的正常温度，为此瞬间温差变化将导致石英表内的防水垫圈提前老化。

The aluminum alloy casting can be rapidly cooled from the solutionizing temperature directly to the agingtemperature, eliminating the room temperature hold of a conventional process.
可使铝合金铸件从固溶温度直接快速冷却到时效温度，省去了常规工艺的室温保持。

Roomtemperature impact ductility decreased with the aging time increasing.
