Problems solved by technology

[0005] The efficiency of the above process or technology is low, the power consumption is large during the curing process, and the consistency of the product is poor. It is unavoidable to avoid the occurrence of unqualified products due to human operation errors and the unqualified rate is also high. After curing, it is necessary to conduct power-on or high-voltage tests.
In particular, manually aligning the head and end of the heating element will inevitably lead to errors that cause the two sides of the product to be non-parallel, and the process of knocking out the corrugated h...
