First of all, the extruded PP Zipper Braided Sleeve is fed, passed through the mold, baked at high temperature, and finally formed. During this period, the size of the tube will vary with the change of temperature and time. This requires the front and rear operators to control the tolerance range at any time.If the normal diameter is below 5MM, the standard of the industry standard is a range of plus or minus 0.1MM. If the inner and outer diameters are between 5-10MM, there will be a standard of plus or minus 0.15MM.
It can be seen that the larger the size of the PP Zipper Braided Sleeve, it does not mean that the mold cannot be opened, but the tolerance will increase with the increase of the size.
