Driven by the rapid development of new energy, rail transit, and smart grids, the demand for high-performance epoxy resin insulated components with superior precision and consistency has never been higher. Recently, our company successfully completed the R&D, integration, and international delivery of a fully automated Static Mixing Vacuum Pouring System, which has been shipped to a leading high-voltage electrical equipment manufacturer in Asia. This milestone underscores our continued breakthroughs in advanced insulation molding equipment.
Project Background
The customer had long relied on manual pouring processes, which led to persistent challenges including inconsistent mixing ratios, residual air bubbles, and fluctuating product yields. These issues made it difficult to meet the stringent reliability and batch-to-batch consistency requirements of next-generation dry-type transformers and insulators. To upgrade their production line and achieve a significant quality leap, the customer launched a global tender and ultimately selected our company as its core process equipment supplier.
Customized Solution
Addressing the client’s critical needs for precise metering, bubble-free pouring, and stable continuous production, we engineered an intelligent static mixing vacuum pouring system featuring the following technical highlights:
High-precision dual-component metering and static mixing technology: Mixing ratio accuracy within ±0.5%, ensuring thorough and uniform reaction between resin and hardener;
Fully enclosed vacuum pouring environment: Chamber vacuum ≤ 1 mbar, effectively eliminating microbubbles to enhance dielectric strength and mechanical performance;
PLC + HMI intelligent control system: Supports recipe management, process parameter traceability, automatic cleaning, and remote diagnostics;
Modular quick-change design: Compatible with various mold sizes, improving changeover efficiency by 60% to support flexible manufacturing;
Compliance with CE and IEC 61010 safety standards: Ensuring operator and equipment safety.
Efficient Delivery, End-to-End Assurance
From contract signing to shipment, our project team overcame challenges such as extended lead times for precision components and delays in the customer’s on-site infrastructure readiness. Through concurrent engineering and agile project management, we ensured all critical milestones were met on schedule. The system underwent comprehensive Factory Acceptance Testing (FAT) at our facility, with the customer’s technical team participating remotely via live video throughout the validation process. The equipment was successfully shipped and has now arrived at the customer’s newly commissioned smart factory, where it is currently undergoing installation and commissioning.
This successful delivery further reinforces our position as a trusted partner in advanced insulation processing solutions—delivering not just machinery, but measurable value, reliability, and peace of mind.
