Industrial Application
Reverse Sensor, Electronic Circuit Board, Electronic Ballast ,air Filters, LED products ,Electronic components,Crafts,Ads modules,
Capacitors, Power supply, Transformer, end cap for filter, solar
junction box ,Power module, Ignition coil, Sensor, Photovoltaic
module, Photovoltaic inverter. Etc
Epoxies, silicones and polyurethane are among the most frequently
used potting compounds. These can be applied to
PCBs,PCBA,capacitors,power electronics, LED lighting, sensors, and
more. Some of the desired properties include good
adhesion,excellent electrical insulation, thermal stability, super
chemical resistance, low shrinkage upon curing, an appropriate
coefficient of thermal expansion (CTE), and suitable viscosity for
the specific application. Formulations can be blended to provide a
balance of these and other properties through careful selection of
resin, agent, and fillers.
Epoxies, silicones and polyurethane are commonly used with fillers
to lower shrinkage, enhance dimension stability, and improve
abrasion resistance. The use of fillers is the critical factor for
obtaining thermal conductivity while retaining electrical
resistance.
Besides ,the liquid potting material must flow easily so that it
completely covers the component, leaving no voids. If air becomes
trapped in the housing, the moisture it contains may cause
corrosion - eventually leading to component or product failure.
Daheng equipment with pre-heat functions that helps the pre-heat
the AB compound in tank in advance to keep a good flow-ability.Good
liquidity helps resin flow into product easily and evenly.
Daheng machine with tank stirring vacuum degas functions ,which can
help compounds to remove air bubble easily and arrived the good
potting status .
Removing air bubbles is very important.Vacuum degassing remains a
critical processing step. The best technique for vacuum degassing
is referred to as "bumping degas" which is alternately pulling and
relaxing a vacuum in 30- to 60-second cycles.
2. High precision valve: high speed, glue off clean, no glue
drawing, no dropping.
3. Core metering pump specially design for different material from
low to high viscosities.
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 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 .
D&H Pump technology1. Two cylinder plunger pumps work by durable motors. 2.The biggest flow volume :24g/s,Repetition accuracy:0.2g.

PLC operation Controlling System1 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
