Recently, Xiamen Taixing Electromechanical Co., Ltd. officially launched its independently developed EVA Foam Molding Machine Water Circulation Vacuum System. This system, centered on a patented four-way valve block integrated design, effectively solves traditional industry pain points such as high leakage, high energy consumption, and complex maintenance. By leveraging stable, energy-saving, and highly adaptable water circulation vacuum technology, it has become the benchmark for vacuum system upgrades in footwear, photovoltaic (PV) encapsulation, and medical packaging sectors.

As the core component of the EVA foaming process, the vacuum system directly determines the product's bubble rate, molding precision, and production efficiency. Xiamen Taixing has deeply integrated oil-free and pollution-resistant characteristics into this system, making it suitable for medium-to-low vacuum scenarios or high-precision production when paired with a primary pump.

Core System Analysis: Four Modules for Full-Process Optimization

The EVA Foam Molding Machine Water Circulation Vacuum System is built around a water circulation vacuum host and integrates four core modules to ensure operational excellence:

• Water Circulation Vacuum Host: Features a patented split impeller design (CN35838695), allowing for impeller replacement in under 30 minutes—an 8x improvement in maintenance efficiency. Equipped with Fluororubber seals, it withstands temperatures up to 180°C and handles complex gases like vinyl acetate decomposition products.
• Four-Way Valve Block Integrated Pipeline: This patented design integrates filters, ball valves, and pressure gauges. By reducing joints by over 50%, it significantly minimizes leakage risks and saves valuable workshop space.
• Intelligent Control & Monitoring: Dynamically adjusts water flow (0.5-2 L/min). When combined with a cooling tower, it reduces energy consumption by 30%-40% compared to traditional liquid ring pumps. It also supports Modbus IoT interfaces for remote monitoring.
• Auxiliary Filtration Module: Options include cyclone separators for dust, activated carbon for VOC treatment, and TAIC anti-corrosion coatings for high-precision PV applications.
