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.

 

Machine Congigurations
Introduction:

1. Working Mode: controlled by PLC module and MCGS touch screen.

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.

8 Tank with silica-dryer which can prevent material especially PU from crystallization .
