Characteristic of Stamping Tungsten Boat

Manufacturing process of tungsten boat is generally stamping at a high temperature. Depending on the different requirements of the finished wolfram boat, Manufacturing process of it can be divided into stamping, welding, sintering, riveting. The following will talk more details about stamping tungsten boat. Stamping (also known as pressing) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining.

First of all, tungsten plate should be blended into a certain angle, or bending the blended workpiece again. After that, it should be pressed into any hollow shape by mould, or bending the hollow mould workpiece further deformation. Afterward the hole or the outer edge of tungsten plate should be folded into a straight wall by mould. Forcing an outward radial force on the hollow member by mould, so that the local diameter can be expanded. After expansion, pressing the outside-in radial pressure on the hollow member so to narrow the local diameter. Next, putting the bloom into the die cavity, squeeze it out from the gap of mould to form the hollow or solid workpiece. Roll the panel into a ball peen whose shape approximate to a close one. Finally, press the bended or stretched workpiece into a right W-boat shape.

The main characteristic of the stamping W-boat is the high rate of final products but it would cause noise pollution. Because that this type of W-boat using the stamping equipment and stamping mould, the accuracy of size and shape the stamping wolfram crucible are much higher. What’s more, it has a long life time and it is not easily to be damaged, therefore, shape of the W-boat from the same production batch is almost the same which quality is also stable. On the other hand, pressure of stamping device is accurate, so that it will not damage the surface quality of the finished W-boat. However, there still exist some disadvantages of it. For example, during the stamping process, the device will produce noise and vibration which would have a great influence on operators. Furthermore, the mould is an essential material for stamping process, so the quality of the mould determines the quality of the W-boat.

Users can make reasonable adjustments to the size of the stamping W-boat as needed.
