When installing a composite ceramic evaporation boat, it is necessary to maintain a certain inclination (slightly higher at the end of the aluminum wire) to facilitate the flow of liquid aluminum to the end of the boat. This is important regarding the added liquid aluminum spreading area, the lifespan of the forward evaporation boat, and the uniformity of the forward coating. The evaporation boat should adhere to the horizontal plane horizontally.

Although the machining quality of the "medium wire" EDM machine has significantly improved compared to the fast wire EDM machine, it still belongs to the category of high-speed wire EDM machines. There is still a significant gap in cutting accuracy and smoothness compared to low-speed wire EDM machines, and the maintenance of accuracy and smoothness also needs to be further improved. It has the characteristics of simple structure, low cost, and low usage consumption.

As a typical product of transition metal molybdenum, molybdenum boat, also known as evaporated molybdenum boat or coated molybdenum boat, is formed by welding or high-temperature stamping of molybdenum sheets or molybdenum based alloys. It is an important sintering carrier for molybdenum powder and other metal powders.
