2K Mixing and Dispenser 2K Mixing and Dispenser Automatic Epoxy Resin Dosing Two Component Potting Polyurethane Dispensing Machine
Why Choose us ! Where to buy epoxy ,silicone ,polyurethane 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 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. Different pumps selection for different adhesives such like epoxy , silicone and PU polyurethane , polymer and other liquidity materials .
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 heating panel 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 .

PLC controlling System
1 Dispensing volume is controlled by the speed of pump's motors ; Glue speed adjustable within the speed range .
2 Machine with detecting function that detect the speed and running time of pumps to ensure the ratio reliability.
3 Adjustable gluing-out volume make sure glue A/B dispense out at the same time from glue valve to get better glue mixing effect .
4 Machine with gel resistance calculator , which prevent the mixture curing inside .
5 You can set single gluing-out and steady gluing-out function to meet up with your different process requirement .
6 Whole machine system and function is controlled by Panasonic PLC and MGCS touch screen .
7 Reserved PLC communication interface, which easy connecting with outside device .
8 Equipped with a safety lock to prevent staff from wrong operation .

We assure 1 year warranty for the main part,also we offer spare part for back up.Please check with sales engineer in detail.
What are your payment terms?
Normally, 30% advance by T/T and balance paid off before delivery.
Are you a factory or trading company ?
We are a factory with SGS certified and more than 20 patents,and cooperate with different customers coverd about 40 countries for over 15 years.
Glue dispenser always drops ?
Drops always happened when valve closed . The reason may be low concentration of glue , big air-pressure or large diameter of needles.
Narrow needles will effect the flow of the liquid and cause back pressure . It will lead to dropping when the valve closed . Too narrow needles will effect the drainage of air when valve start to work, but it can be solved if change suitable needles .
Conical needles with less back pressure and liquid flow smoothly .
It is better to drainage of the air advance or use no-foam glue or deaeration to avoid the air cause dropping after valve closed .
Glue dispensing not evenly ?
The problem cause mainly because of the storage flow pressure tank or air pressure is not stable.
Inlet pressure regulating table should be set lower 10-15psi than factory minimum pressure . The pressure in pressure tank should be set upper than the middle pressure of regulating table . It should be avoided to use the pressure lower than the middle pressure of regulating table .
Control pressure of rubber valve at least higher than 60psi to assured glue evenly .
We should check the glue output speed at last . The glue is uneven if the time less than 15/1000s , the output speed more longer , the glue dispensing will be more stable .
Slow flow velocity ?
It should be changed the pipe from 1/4 to 3/8 if the flow velocity too slowly .
The pipe is the shorter the better if no requirement .
Air in the fluid ?
Excessive fluid pressure and short valve opening time may lead to the air infiltration liquid . We can use the conical needles and reduce fluid pressure .
Instant glue (quick adhesive) blocking in valve connector and pipes?
This problem is caused by heavy moisture and recycle instant glue . We should make sure to use new instant glue and wash the pipes with dry acetone . Make sure air dry and add filter between plant air pressure and valve .
UV glue (UV curing glue )
Make sure to use black pipeline.
Don't add new UV glue to old UV glue in pressure tank , we should drain off the old UV glue before pouring new UV glue into pressure tank because the UV glue will produce bubble after a period of time and lead to glue dispensing unevenly .
