In the manufacturing of high-end electrical equipment, electronic components, and composite materials, vacuum casting of epoxy resin is a core process essential for ensuring product insulation, mechanical strength, and long-term reliability. Traditional dynamic mixing casting methods are prone to introducing bubbles and suffer from issues such as uneven mixing and difficult-to-control solvent volatilization. Addressing these industry challenges, our independently developed VRC Series Static Mixing Vacuum Casting Equipment, with its innovative design philosophy and exceptional process stability, is becoming a benchmark solution leading industry upgrades.
Technical Principle of Static Mixing Vacuum Casting Equipment
The core of the VRC series equipment lies in the perfect integration of efficient static mixing technology and a full-process vacuum environment. The system operates under a consistently high vacuum, homogenizing two-component epoxy resin through a unique static mixer. This process eliminates the need for a dynamic stirring shaft, completely preventing the risk of air leakage potentially caused by shaft seals and eradicating the source of bubble introduction. Throughout the entire process—from degassing, mixing, and conveying to casting—the resin remains in a precisely controlled vacuum and temperature environment, thereby achieving perfect casting results characterized by bubble-free, high permeability, and zero volatilization.
