Our engineer changed the design of muffler 0F6591. The updated drawing 0F6591-3.dwg is attached here. We changed the outside wall to double wall, but the total wall thickness is still 1.2mm. This means that you need to use double 0.6mm sheet metal to form the wall. We also changed the inside design by eliminating the fiber glass. Please update your quotations for this revision.

Have you found the high temperature paint that can withstand 800 degrees C? Please quote us two prices. One is to use aluminized steel as before. Another is to use regular steel with outside painted with high temperature paint (800 degrees C).

We will use your existing tooling. So we will change the oval section width to 247.6mm instead of 240mm and the height 101.6mm instead of 100mm. Please update your quotation as soon as possible.

我们的工程师对OF6591消声器的设计作了些改动。名为OF6591.dwg的最新图纸附在这里。我们将外墙改为双线墙，但墙的总厚度仍为1.2毫米。

这就意味着您需要用两根0.6毫米厚的金属片来构成这墙体。同时我们也删去了内部设计的玻璃纤维材料。请根据我们的修改更新你的报价单。
请问你找到了能耐800度高温的油漆吗？如果有，请提供我们两分价格。一个是跟以前一样的铝合钢的价格。另一个是用普通钢筋结合耐800度

高温油漆的价格。
我们将会采用你现有的加工程序。所以我们将椭圆部分的宽度从原来的240毫米改为247.6毫米，高度由原来的100毫米改为101.6毫米。请尽快更新你的报价单
