What is the situation of uneven wall thickness of the hose caused by the eccentricity of the Tinned Copper Braided Sleeve?

If only an ordinary Tinned Copper braided sleeve has uneven eccentric wall thickness, then the Special Material Braided Sleeve cannot achieve faster production efficiency. The second is that the production line operator used it improperly to adjust the speed of the threaded rod of the extrusion equipment. It is relatively fast, but the extrusion pressure has not adapted, which will easily lead to uneven extrusion force at the die mouth, that is, the extrusion conditions of the Tinned Copper Braided Sleeve have not reached a balance point, and the tinned copper tube produced in this way Copper braided sleeves are very prone to misalignment.

Secondly, it is also possible that this kind of problem may also occur when the extrusion speed or extrusion pressure is slow, or the operator wrongly estimated the wall thickness of the Tinned Copper Braided Sleeve and the vulcanization of the post-baking tunnel. Conveyor belt speed, in summary, the former has a high probability of eccentric wall thickness of the tinned copper braided casing, and it is not complicated to solve the problem of eccentric tinned copper braided casing, just need to adjust the extrusion pressure of the extruder or the thread Just adjust the rod to the balance point accordingly.
However, there are also some special types of products, which are large-diameter thin-walled Tinned Copper Braided Sleeve or thick-walled Tinned Copper Braided Sleeve. Why is this Tinned Copper Braided Sleeve prone to uneven eccentric wall thickness? It is because the caliber is large and the wall thickness is very thin, such as: silicone aeration tube diaphragm, large-diameter Tinned Copper Braided Sleeve, such products, the mold needs to be opened according to the size of the outer mold and the inner mold size Very close, so that when the machine is extruding, the raw material is pushed to the mold mouth through the threaded rod. At this time, the silicone is an unvulcanized product (that is, unshaped), because the extrusion speed of this large-diameter Tinned Copper Braided Sleeve It needs to be slowed down, and the extrusion speed cannot be accelerated like normal Tinned Copper Braided Sleeve. Therefore, many operators cannot control the extrusion pressure and the advancing speed of the threaded rod, which leads to large diameter Tinned Copper Braided Sleeve. The wall thickness of the left and right sides of the braided sleeve is inconsistent. This kind of product is very wasteful of manpower and needs to be adjusted many times. The balance point of this Tinned Copper Braided Sleeve is very difficult to find, and it often takes a lot of material to determine it. Manufacturers are quite disgusted with this kind of Tinned Copper Braided Sleeve, so it is very easy to have uneven wall thickness and eccentricity of the extrusion product of this relatively unique Tinned Copper Braided Sleeve.
In summary, it is mainly divided into two categories, one is caused by the carelessness of the operator or the extrusion manufacturer, and the other is some special products that are prone to problems due to technical limitations, such as Tinned Copper Braided Sleeve, which are extruded eccentrically. Thin-wall problems often occur, but as long as the manufacturer is careful, strictly controls, and keeps the original intention, these are not problems.
