Can Sealer Fault Analysis

Machines fail over long periods of use, and sealers are no exception. What are the possible failures of sealing machines in industrial production? The following briefly introduces the two major failures that are prone to occur in the long-term use of the sealing machine, their causes and treatment methods.

1. Irregular marks appear in the sealed area. This is a common fault due to the large number of irregular uneven marks on the surface of the cold press. Over time, when the sealer works, it absorbs substances such as dust, which attach to the sealer and cause uneven heating, thus creating bubbles. The way to deal with such failures is simple, just clean the sealer or replace the cold glue machine regularly.

2 Insufficient sealing strength. Poorly sealed products are easily contaminated, which not only shortens the shelf life of the product and causes losses to manufacturers, but also affects the consumer experience. Therefore, insufficient sealing strength is an important failure of the sealing machine. Such cases are often caused by unsuitable pressure of the cold press rubber wheel, too fast heat sealing speed or insufficient temperature. At this time, it is only necessary to increase the heat sealing temperature, reduce the heat sealing speed and increase the cold pressing rubber wheel pressure.
