Core Technology: vCPT Series Static Mixing Vacuum Casting System

Designed specifically for current and voltage transformers as well as APG casting processes, the vCPT series offers fully automatic in-line or batch配料 options. The system integrates:

• High-precision metering

• High-temperature vacuum thin-film degassing

• Constant temperature control

• Fully automated programmed casting

Static mixing technology eliminates mechanical stirring. Through specially designed internal geometries, the two-component resin is repeatedly divided and recombined during flow, achieving bubble-free, non-laminar, and perfectly homogeneous mixing.

Four Essential Factors for Zero-Defect Casting

Successful casting relies on the synergy of four elements:

Dry materials + Thorough vacuum + Matched temperature + Scientifically controlled curing

GOOGIO Machinery’s vacuum casting system maintains a full vacuum environment from material preparation to casting completion, effectively eliminating voids and reducing partial discharge levels – ensuring excellent electrical insulation performance and defect-free surfaces.

Flexible Configuration, Smart Production

• Modular design adapts to various transformer sizes and production needs

• Intelligent control system stores multiple process recipes for fast changeovers
