Plate Heat Exchanger Solution for Guangxi Zhengrun’s Precision Aluminum Foil Rolling Process

Guangxi Zhengrun New Materials Technology Co., Ltd., a subsidiary of Guangxi Investment Group, is a nationally recognized high-tech manufacturer specializing in high-purity electronic aluminum foil for demanding industrial applications. With an annual production capacity of 18,000 metric tons, the company’s products serve fast-growing sectors including electric vehicles, 5G communications, aluminum electrolytic capacitors, and advanced electronic components.

Producing high-performance electronic aluminum foil requires extremely stable rolling conditions. Even minor fluctuations in lubricant or emulsion temperature can affect foil thickness, surface finish, rolling precision, and product consistency.

To support its precision rolling operations, Guangxi Zhengrun implemented a dedicated plate heat exchanger solution designed to provide accurate temperature control for rolling oil and emulsion cooling, improving both production efficiency and long-term equipment reliability.

The Challenge

High-speed aluminum foil rolling generates significant heat during production. Without effective process cooling, elevated temperatures can reduce lubricant performance, accelerate fluid degradation, increase energy consumption, and negatively impact product quality.

For electronic-grade aluminum foil, maintaining stable rolling conditions is especially critical due to the extremely tight manufacturing tolerances required.

The cooling system needed to:

* Maintain precise rolling oil temperatures

* Stabilize emulsion cooling throughout continuous production

* Improve lubrication and cooling performance

* Extend lubricant and emulsion service life

* Reduce energy consumption and operating costs

* Support uninterrupted precision rolling operations

* Deliver reliable long-term performance under demanding industrial conditions

The project required a heat transfer solution capable of providing accurate, continuous process temperature control without interrupting production.

Our Solution

To meet these demanding process requirements, Beijing Generalway supplied a custom plate heat exchanger system specifically engineered for aluminum foil rolling applications.

The heat exchanger utilizes a high-efficiency corrugated plate design that maximizes heat transfer while maintaining a compact installation footprint. The optimized flow channels provide excellent resistance to fouling and clogging, ensuring reliable operation even under continuous industrial service.

The system precisely regulates the temperatures of both rolling oil and emulsion circuits, allowing lubrication and cooling systems to operate within their optimal temperature ranges throughout production.

Stable temperature control improves lubricant viscosity, enhances cooling performance, and supports consistent rolling conditions, helping maintain foil thickness accuracy and surface quality while reducing unnecessary wear on production equipment.

By extending the service life of rolling oil and emulsion fluids, the system also reduces consumable costs and minimizes maintenance requirements.

Designed for continuous operation, the plate heat exchanger integrates seamlessly into the production line while delivering dependable performance, high thermal efficiency, and long-term operational reliability.
