EPC Edge System: This system also consists of a sensor probe, a control system, and a servo valve. By using sensors to detect changes in the edge position of the strip, the system feeds edge deviation signals into the control system, which then activates hydraulic cylinders to guide the winder and align it with the incoming strip’s position. This ensures precise coiling of the strip, ultimately achieving perfectly aligned edges on one side.
Modern CPC/EPC systems achieve a control accuracy of ≤±1mm, utilizing high-frequency light sources and high-precision sensors. They feature high sensitivity and strong anti-interference capabilities, enabling stable operation even in complex environments. The system supports multiple operating modes, including automatic control, self-centering, manual control, and single-step control, catering to diverse production needs.

Aluminum alloy casting is a manufacturing process that involves pouring molten aluminum alloy into a mold, allowing it to cool and solidify into the desired part shape. It is widely used in industries such as automotive and aerospace. The main casting methods include sand casting, metal die casting, die casting, and low-pressure casting, each suited to different levels of complexity and production volumes—for instance, sand casting is ideal for large components, while die casting enables high-precision, high-volume production.
CNC machining is a modern mechanical processing technology that achieves high precision and efficiency through computerized, digital control. As a core component of advanced manufacturing techniques, it is rapidly advancing toward even greater precision, higher efficiency, and increased intelligence—making it an indispensable key technology in today’s industrial manufacturing.
