Machine details:
Dispensing and Potting Under Vacuum Machine bubbles disappear potting machine
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 electronic components & 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.

Detailed drawing :
Working process :
1. Quantify metering system with high precision(±1-2%), suitable for middle to low viscosity two component material ratio .
2. Adapting foreign technology that further improved sealing position and metering in good accuracy.
3. Graphite sealing components ; stainless pump ; stainless connector ensure the pump with long lifespan and anti corruption .
4. Metering pump have Daheng high pressure and high precision double liquid valve , with vary sealing methods and adjustable retract function, that is convenient for glue valve cleaning and precision glue dispensing .
5. Controlling system can program resin dispensing in high precision and reserved many glue dispensing programs .
6. Inset self-check controlling system module makes fault detection rapidly .
7. Through different collections of metering pumps realize the changeable ratio from 1:1 to 10:1 .
8. Keep steady dispensing design , the glue-amount can be adjusted from 0.5g/s~12g/s per single pump, ab pump dispensing amount can be set accordingly to ab ratio .
9.Double cylinder plunger pump's structure especially suitable for high additive ,high density materials . The lifespan is designed for 10 years .
Valve technology :
1.The mixing motor drive the blade to stir the glue evenly. The mixing process totally seal ; the double liquid valve and mixing pipe filled with glue that assured glue mixing without any air bubble;the valve through turn on-off the air-cylinder to keep glue suck well and prevent glue from dropping .
2. Stirring motor speed is 2000r/m, which can fully stir glue evenly.
3. Mixing pipe is consumable that from Sulzer Mixpac MR13-12; as per machine downtime , the mixers should be cleaned or soaked in cleaning fluid.
4.Dynamic mixing with stirring detecting function(optional) that ensure glue mixing evenly .
5. Stainless design of the glue touch surface to capture more higher material compatibility .
6.Glue valve with flow-back prevent function that can prevent mixture from dropping when stop dispensing .
7. Sealing parts of rod shaft adopt imported parts to keep more higher durability .
8. The self-cleaning function make machine cleaning more easier that you needn't dis-assembly the parts to wash . Cleaning time and cleaning times could be set in the touch screen.
