We are pleased to announce the successful design, manufacturing, and delivery of a custom epoxy resin casting system to a leading European power equipment manufacturer. The client specializes in the production of high-voltage insulation components, instrument transformers, and dry-type transformers. With the global surge in grid modernization, their existing production line could no longer meet the growing demand for high-precision, high-volume casting operations.
The client explicitly outlined three core requirements:
High-Precision Metering and Mixing: The mixing ratio between epoxy resin and hardener must be controlled within ±0.5%.
Vacuum Casting Stability: The system must maintain a full-process vacuum environment to eliminate air entrapment and voids.
Modular Scalability: The equipment must include provisions for future capacity expansion to avoid redundant investments.
Tailored Solution: Technology-Driven Custom Development
Leveraging over a decade of expertise in epoxy resin casting equipment, our engineering team implemented three critical enhancements based on our standard platform to meet these stringent specifications:
Upgraded Precision Metering System
Dual servo-driven piston pumps combined with high-accuracy mass flow meters enable real-time closed-loop feedback, achieving a mixing ratio accuracy of ±0.3%—significantly surpassing industry standards.
Optimized Vacuum Casting Chamber
Constructed from fully welded 304 stainless steel, the chamber achieves an ultra-low leak rate of <1×10⁻⁹ Pa·m³/s. An integrated multi-station rotary table allows simultaneous casting of up to six large insulating components per cycle, boosting throughput by 40%.
Intelligent Control System
Featuring a 15-inch HMI interface, the system includes recipe management, self-diagnostic capabilities, and remote maintenance functions. After just three days of training, the client’s technicians can operate the system independently, dramatically lowering the barrier to use.
This successful delivery is no coincidence—it reflects our long-standing commitment to innovation and excellence in the epoxy resin casting field. From standalone machines to turnkey production lines, and from standard models to deeply customized solutions, we consistently uphold our delivery principles: On Time, Precise, and Reliable.
