Analysis Of Several Factors Leading To Substandard Wall Thickness Of Glass Fiber Pre-insulated Casing

In actual application, if the wall thickness of glass fiber pre insulated sleeve is uneven, serious consequences will occur. The most direct impact is that the local voltage resistance level of glass fiber pre insulated junction sleeve is not enough and it is easy to be broken down. So what factors cause the uneven wall thickness of glass fiber insulated joint sleeve in production? The following is the answer from the professional technical engineers of glass fiber tube manufacturers.
1. Blank tube weaving
During the weaving process of the blank tube, the machine speed is unstable, resulting in differences in the density of the braided tube. This is a common problem of old braiding machines. As a well-known enterprise in the industry, Wojie New Materials has replaced all its equipment with new CNC equipment, which can completely eliminate the existence of this problem.
2. Silicone rubber extrusion
The silicone rubber glass fiber tube in the glass fiber casing must first extrude the inner rubber tube before the blank tube is woven. The temperature of the inner rubber tube is not up to the requirements or the extrusion wall thickness is uneven; if the wall thickness of the inner layer of the silicone tube itself is uneven, it will directly lead to the wall thickness of the finished glass fiber casing not meeting the standard.
