Large Custom Riveted Tungsten Evaporation Boat Tungsten Boats For Ship Industry Sintering Furnace Vacuum Coating
Large Size Customization Riveted Tungsten Boat
1. Description of a Customized Large Tungsten Riveted Boat:
The tungsten boat becomes a riveted tungsten boat when two tungsten plates are joined together using rivets. Drilling, spot facing, deburring, inserting rivets, pressing the top die (top handle) against the rivets, and machine riveting are the steps used to create the form. The connecting of the rivets improves the tightness of the connection and increases the strength of the riveted tungsten boat. The riveted tungsten boat can be made larger in size upon request.

2. Production Process of Large Size Customization Riveted Tungsten Boat:
Active riveting, fixed riveting, and sealed riveting are the three types of riveting. During active riveting, the joints can rotate with each other, and the flexibility is strong. The joints in the fixed riveting cannot move with each other. Workpieces made of hermetic riveting are gas and liquid-tight. Generally, the tungsten boat processing adopts the method of sealing riveting. Sealed riveting is to use ring groove rivets, high shear rivets, threaded hollow rivets, blind rivets, etc. Connection Type. First, drill the joint of the tungsten plate, then deburr, then insert the tungsten rivet, and finally use the top die (top handle) to hold the rivet, and use the riveting machine to rive the tungsten boat into shape.
