Static Mixing Epoxy Resin Vacuum Casting Equipment

Static mixing epoxy resin vacuum casting equipment separates the three steps of dosing, mixing, and casting: resin and hardener are stored in A and B tanks, each with its own heating, stirring, and vacuum degassing. During casting, servo-driven high-precision metering pumps deliver the two components at the set ratio and flow rate to a static mixer, where they are mixed and discharged simultaneously.

The key difference is that the two components never touch until they enter the mixer. Traditional dynamic mixing puts all materials into one mixing tank and heats them, so the material starts reacting in the tank, viscosity changes over time, and permeability worsens toward the end of casting; every wetted part also needs cleaning or material change, wasting time and material. Static mixing stores and pre-treats the components separately, so the resin is discharged at uniform, lowest, and most stable viscosity, and production can resume directly after a short shutdown.

Casting takes place in a vacuum chamber, where the resin is degassed and molded under vacuum, significantly reducing bubbles and voids and improving density and product consistency. After casting, the equipment can perform one-touch automatic cleaning of the mixing head (casting head), washing away residual resin before changing materials.

Core Features

• Mixing error ±0.5%: servo-driven high-precision metering pumps deliver at the set ratio and flow rate, and the static mixer ensures thorough, uniform mixing.

• On-demand ratio control: mix only what you need, when you need it; adjustable casting speed suits both high-volume continuous production and intermittent small batches.

• Full isolation of the two components: tanks and lines are separate, fluids never contact each other, no premature reaction or failure, no cleaning needed for short shutdowns.

• Vacuum degassing and vacuum casting: A and B tanks can be independently evacuated for degassing and preheating; casting is done in a vacuum chamber for dense molding with few bubbles.

• Independent heating and stirring: A and B tanks each have electric stirring and heating, ensuring uniform preheating and stable viscosity.

• Automatic recirculation: lines have a recirculation function, returning fluid to the tank during shutdown to prevent curing and clogging.

• One-touch automatic cleaning: after casting, the mixing/casting head is automatically cleaned, reducing manual disassembly and resin waste.

• PLC one-person operation: PLC program control + touchscreen operation; ratio, casting time, total casting volume and other parameters are set visually; vacuum level and temperature are monitored throughout; faults are shown on screen.
