Working Principle
Step 1: Material Preparation and Tank Conditioning
✅Heating: Electric heating bands reduce viscosity to ensure smooth flow.
✅Agitation: Continuous stirring prevents filler sedimentation (e.g., thermal conductive powders).
✅Vacuum Degassing: Removes micro-bubbles under negative vacuum pressure (-0.095 MPa) prior to feeding into pumps.
Step 2: High-Precision Metering and Proportioning
✅Dual servo motors drive precision gear or piston pumps to draw Resin (A) and Hardener (B) from separate stainless steel pressure vessels.
✅System monitors volumetric flow rate continuously to enforce precise stoichiometric mixing ratios (1:1 up to 10:1).
Step 3: Mixing Mechanism
✅Dynamic Mixing: A high-speed rotating motor mixes viscous or high-ratio liquids inside an easy-clean dynamic chamber.
✅Static Mixing: Helical mixer nozzles force material layers to cross-divide repeatedly for low-viscosity or quick-curing formulas.
Step 4: Dispensing and Potting
✅Servo-driven XYZ robotic gantry or multi-axis CNC system executes preset potting trajectories (dots, lines, arcs, continuous potting) over the workpiece.
✅Automatic purge cycles flush the mixing valve with solvent or Component A to prevent internal curing during downtime

Frequently Asked Questions (FAQ)
Q1: What is a resin dispensing machine and dosing system?
A: It is an automatic meter-mix unit to pump, proportion, mix and dispense two-component resin such as epoxy, silicone and PU. It applies resin locally on workpieces instead of full cavity potting.
Q2: What materials can this resin dosing system process?
A: It works for 2-component epoxy resin, silicone resin, PU polyurethane resin and other similar medium-low viscosity dual-part adhesives.
Q3: Can I adjust the resin mixing ratio?
A: Yes. The mixing ratio is adjustable via the touch screen, normally ranging from 1:1 up to 10:1 to fit different resin formulas.
Q4: What dispensing patterns does it support?
A: It supports dot, line, circle, arc, curve and area coating. Multiple dispensing programs can be saved and recalled quickly.
Q5: What is the dispensing accuracy?
A: Our standard resin dispensing system reaches ±1% dispensing accuracy with stable metering pumps, which keeps consistent resin volume for every cycle.
Q6: What industries use this resin dispensing machine?
A: Widely used for automotive electronics, PCB components, sensors, LED modules, new energy parts and electronic bonding projects.
Q7: What is the difference between resin dispensing system and vacuum potting machine?
A: The resin dispensing & dosing system is for local coating, bonding and selective resin application. A vacuum potting machine fills the whole internal cavity of parts under vacuum for full encapsulation.
Q8: Can the machine be customized?
A: Yes. Working travel, pump structure, dispensing valve, rotary table or conveyor integration can be customized according to your product and production plan.
Q9: Do you provide after-sales support?
A: We offer remote debugging, video operation training and global spare parts supply. CE compliant for overseas factories.
Q10: Can it connect with an automatic production line?
A: Yes. It can integrate with rotary tables, conveyors and robots to build fully automated dispensing stations.
