What is the reason why the blister high frequency packaging machine does not weld?

The upper and lower double blisters of the packaging machine are heat-sealed and trimmed, and the blister and cardboard are heat-sealed and trimmed. If you encounter the problem of no heat sealing or uneven heat sealing during this process, it may be due to the following reasons.

1. The mold should be kept at a constant temperature. Changes in mold temperature can lead to unstable quality.

2. Try to increase the high frequency output and reduce the high frequency output time. Because fires are usually caused by materials that cannot withstand high temperatures.

3. Check whether the mold is parallel to the lower platen.

4. The mold size does not match the high frequency machine, which reduces the effective output power of the machine.

5. The transformer or AC contactor is in poor contact, so that the output current is a virtual current.
