Heat shrink tube expansion

Release date:2020-09-09 author:admin Click:

Heat shrink tube expansion is one of the important production step during the whole heat shrink tube production process. Without this process, it is impossible to produce qualified heat shrink tube.
 
Before introducing heat shrink tube expansion, let us first introduce the overall production process of heat shrink tube. For customers who are not familiar with heat shrink tube, the production process is relatively complicated, including pelletizing, extrusion, irradiation, expansion, and packaging. In fact, compared with other products, the process is not as complicated as imagined, heat shrink tube includes multiple processes from the beginning of production to the final product packaging. Therefore, the production cycle of this product is long. This is why the customer feels that the tube is out of stock but cannot be shipped out in time. The production cycle of heat shrink tube is about 7 days. If the customer is particularly anxious, we will arrange it as soon as possible.
 
Heat shrink tube expansion, the irradiated heat shrink tube will have the shrinking effect. It can be expanded at a higher temperature through the expansion mold to make the tube larger in diameter, and at the same time, it can be quickly cooled to shape it. At present, the shrinking ratio of heat shrink tube produced by Suzhou Fibo is 2:1. For example, heat shrink tube with the diameter of 20mm in the extruded state, after heat shrink tube expansion, finally shows the diameter of 40mm.
 
Heat shrink tube expansion, naturally we need to mention the expansion machine. At present, our Suzhou Fibo plant includes two types of machines: oil expansion and dry expansion. The former means heat shrink tube will be expanded using glycerin. This is a common method used in our industry. Dry expansion means that glycerin is not used. It is also called a glycerin-free expansion machine. This is a more advanced equipment. In our industry, the utilization rate is lower. In 2019, For expanding our production scale, we purchased several glycerin-free expansion machines, at the forefront of the industry.
