Working principle ：
Compound materials A & B are kept in two tanks separately. There are two sets of metering pumps inside the machine for metering A and B resin by setting ratio, draining out material individually from tank A & B. Liquid A & B mix with each other in the mixer pipe and dispensed out according to the programmable data

1. Stainless panel vacuum pressure tank which can bear negative pressure of inner tank .2. Tank with motor stirrer that prevent the glue from sediment and keep the potting material in constant temperature.
3 Tank with top/ high /low liquid sensors that ensure alarm warning when liquid higher or lower the setting level .
4 Tank with vacuum degas (degas time can be set through touch screen), so the material can be re-feeding through vacuum negative pressure .
5 Tank with pressure releasing ball valve ; the bottom of tank reserved back-flow connector and river closure ball valve.
6 Tank with heater which can preheat materials to assure good flowability .
7 Tank with artificial feeding mouth that can be added glue appropriately by hand .
8 Tank with silica-dryer which can prevent material especially PU from crystallization .

Self-Cleaning：

Turn the cleaning ball valve to the liquid position;
1. B) The cleaningswitch points to "air" and uses compressed air to discharge most of the mixturein the mixing tube;
2. C) The cleaningswitch points to "liquid". If there is a dynamic mixing motor, turn on the dynamic mixing motor before changing the clean switch;
3. D) After cleaning, the cleaning switch points to "air" and usescompressed air to clear the cleaning liquid in the mixed tube;
4. E) The cleaning switch points to the middle positiononce finished.
