We Daheng Automation specialize in different types of potting and dispensing system. No matter what your resin application requirements look like: we can do most of them in our fully equipped lab. We can handle 1- and 2-component polyurethanes, epoxies, acrylics, silicones, temperature, humidity and UV curing materials. They can be from low- to high-viscosity, filled or unfilled and even high abrasive for thermal conductivity.
Potting and encapsulation is the process of embedding products & assemblies in a liquid resin (potting compounds) to protect them against rough environment conditions. Potting can be performed in atmosphere pressure or even under vacuum, if high voltage insulation and high temperature differences are needed. Encapsulation of parts will stop corrosion of metals and reduce damage caused by vibration and mechanical stress.
We offer automatic ,se-mi automatic fluid dispensing potting machine and the related production line and vacuuming systems .

Introduction :
1. Working Area: controlled by PLC module and MCGS touch screen.
2. High precision valve: high speed, glue off clean, no glue drawing, no dropping.
3. Gear pump special for transparent glue. 4. Mix glue A & B more evenly; no more or no less for agent B.
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.
Tank system technology:
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 artificial feeding mouth that can be added glue appropriately by hand .
7. Tank with silica-dryer which can prevent material especially PU from crystallization .
D&H Pump technology
1. Two cylinder plunger pumps work by durable motors.
2. The biggest flow volume :24g/s,Repetition accuracy:0.2g.
3. Also Suitable for high viscosity glue: 50cps~35000cps.
4. Suitable for big flow dispensing or slight flow dispensing.
5. Suitable for frequent start and stop dispensing.
6. Anti-wear, Anti-corrosion, super long life time.
