With the increase in business volume, more and more customers are inquiring about spinning crucibles, such as nickel spinning crucibles, tantalum spinning crucibles, molybdenum spinning crucibles, etc. So what is the process of spinning crucible? Let's talk today.
The spinning process is to clamp the metal blank on the spinning machine, and the spindle drives the mandrel and the blank to rotate. At the same time, the spinning wheel squeezes the material from the side of the blank onto the rotating mandrel, causing the material to undergo point-by-point continuous plastic deformation, thereby obtaining hollow rotary body parts of various shapes.
At the same time, the state of the raw materials, such as hard, soft, and semi-hard, will affect the spinning effect. For example, when the raw material is in a hard state, if the wall thickness of the crucible is required to be 3mm, spinning a 3.5mm slab will definitely not be successful because the slab is too hard and the machine cannot push it at all. If 3mm semi-hard material is used, the machine can push it, but the wall thickness tolerance will be large. At this time, the 3mm slab will be turned into a crucible with a wall thickness of 1.8mm. Therefore, the choice of material state and slab thickness will affect the final parameters of the crucible.
Therefore, if you are not familiar with the material and its condition, the cost of trial molding is very high. Maybe a slab is used for mold testing and is immediately scrapped.
Through a simple description, I believe everyone can understand why the delivery time of spinning crucibles is longer than that of welding crucibles, and the tolerances are relatively large. The price will be higher because the spinning process is more complicated than welding and the cost of trial and error is higher.
