PD2000II is using the composite materials electrodynamics induction sealing technology, it adopts intermediate frequency power and can deliver great effective power, its output current changes according to the load, It will stop automatically when there is wide. A special induction plate is installed,which ensures complete screening and good cooling condition, so that the machine is characterized of short sticking time great fastness, high speed, simple operation and stable capability, even if the mouth of the bottle is plastered with all kinds of liquor, the machine still can seal perfectly. Besides, the machine has protected functions which can prevent from over current, over voltage, under voltage and lacking of water. And it also has functions of continuous counting and automatic rejection to caps without aluminum foil. The product conforms to the requirements of GMP completely.
