Working Principle

Step 1: Material Preparation & 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 & 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 & 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
