Tungsten boat type
1,Stamping tungsten boat refers to the tungsten crucible prepared by hot stamping the tungsten plate to produce plastic deformation.
Stamping tungsten boat has stable quality, high accuracy of size and shape, high yield, wear resistance, high temperature resistance, good conductivity and thermal conductivity, and low price. It is widely used in various vacuum coating industries such as picture tube mirror, electron beam painting, household appliances and so on. However, the stamping process will produce noise and vibration, and the quality of the die determines the quality of the tungsten boat.
2,Sintered tungsten boat can be used to prepare tungsten powder, it is an important carrier for the production of tungsten powder, sintered tungsten boat than vacuum sintering has advantages, can reduce the harmful substances in the atmosphere. Moreover, it is also conducive to the removal of adsorbed gas, residual gas in the pores and reaction gas products, and has an obvious effect on promoting the shrinkage of tungsten oxide in the later sintering period. However, due to the high sintering temperature, even if part of the waste heat is recovered, a large amount of waste heat will be discharged.
3,Evaporation type tungsten boat refers to the tungsten boat used in the vacuum evaporation coating industry.
The evaporative tungsten boat is equipped with a tungsten boat cover, which is different from other tungsten boats., the general tungsten boat cover is provided with an evaporation circle hole, the aperture is 1mm, the hole spacing can be 2mm. The evaporation hole on the tungsten boat cover can not only effectively prevent raw materials from sputtering out of the tungsten boat, ensure the quality of the finished product, but also save raw materials, but also conducive to the sublimation and evaporation of the material, and improve the coating efficiency.
4.Riveted tungsten boat refers to the tungsten boat obtained by riveting multiple pieces of tungsten plate with rivets, which has high strength, flexible disassembly, removable, and can be reassembled, so it is easy to replace damaged parts or check and troubleshoot faults, and the use of tools is flexible, simple, and relatively low price.
Riveted tungsten boat production technology
(1) Drill holes at the joints of the tungsten plate to remove burrs.
(2). Insert tungsten rivets.
(3). Use the top die (top handle) to hold the rivets, and use the rotary riveting machine to rivet the tungsten boat into shape.
5.Folding tungsten boat refers to the tungsten boat obtained by repeatedly folding and forging of the tungsten plate and folding its two ends after processing, with high hardness and toughness, the effect of repeated use is better.
Folding tungsten boat production technology
(1). Press the tungsten plate into a thin sheet that meets the size and thickness.
(2). Bend the sheet to a certain Angle by heating it at high temperature.
(3). Processing into the size required by customers.
Do you know how tungsten boats are produced?
1. Use a mold to bend the tungsten plate to a certain angle, or press and bend the bent part again.
2. Deep drawing is to press the die tungsten plate into hollow parts of arbitrary shape, or further deform the hollow parts.
3. Turn the hole or outer edge on the tungsten plate into a straight wall with a die.
4. The die can be used to increase the radial force on the part, so that the layout diameter can be expanded
5. Apply radial pressure from outside to inside to the mouth of the hollow part with a die to reduce the local diameter.
6. Place the blank in the die cavity and press it to extrude it from the die gap to form hollow or solid parts.
7. Roll the end of the sheet into a closed round head to process parts similar to hinges.
8. Deformation method for enlarging the radial dimension of a hollow blank or tubular blank on a certain part.
9. Press the bent or drawn workpiece into the correct shape of tungsten boat.
Tungsten boat application
Tungsten boat is mainly used for evaporation in vacuum evaporation coating process: powder, particles, high price metal, high temperature refractory metal powder, can also be used to evaporate indium wire, tin wire, aluminum wire, copper wire and other low melting point materials.
Tungsten's melting point is 3610 degrees, higher than molybdenum, so many molybdenum boat can not evaporate products are used to vaporize tungsten boat, so it is mainly used for vacuum coating evaporation aluminum plating, vacuum copper plating, vacuum gold plating, vacuum silver plating, vacuum nickel plating, vacuum indium plating, vacuum chromium plating, vacuum tin plating, vacuum silicon plating and other processes
Packaging and logistics
Tungsten boat is packed with plastic paper inside and carton outside
It is recommended to use four international express transportation, or sea and air transportation
