Web material deviation correction

The high-speed, high-precision, and highly efficient automated processing of coil materials places increasingly stringent demands on the control of their lateral positioning. Equipping the system with a high-performance automatic web‑centering mechanism is key to boosting production capacity and improving yield. During unwinding, intermediate handling, and rewinding, coils inevitably experience lateral displacement (deviation). Therefore, web‑centering systems can be installed at any of these three stages as needed to ensure the coil passes through designated positions with exact accuracy. The web‑centering system is an automated control system comprising a controller, edge‑ or line‑sensing sensors, electric actuators, and a correction mechanism. The sensing elements detect the relative position of the coil's edge, a reference line, or a color mark, converting this information into electrical signals that are sent to the controller. The controller compares these signals with the setpoint, and based on the deviation, it outputs a proportionally adjusted signal to the electric actuator to effect immediate correction.

Micron Dust Removal

During the production, processing, and transportation of materials and products, static electricity on material surfaces can cause them to attract or accumulate microscopic dust, thereby affecting product quality. As cleanliness requirements continue to rise across various industries, the removal of minute impurities and particulates has become increasingly critical. Non-contact surface cleaning offers advantages such as contactless operation, compact equipment, low cost, minimal consumable usage, and ease of implementation, leading to rapid growth in numerous sectors in recent years. Senming Industrial's comprehensive range of roll‑stock, sheet‑stock, edge‑trimming, and custom‑shaped components is extensively deployed in China's high‑tech industries—including lithium batteries, photovoltaics, hydrogen energy, display panels, chips, semiconductors, printed circuit boards, and optical assemblies—as well as in traditional sectors like specialty paper, functional films, printing and packaging, high‑end coating, and automotive leather.

Tension Control

Tension sensors utilize the strain‑gauge principle to measure web tension, delivering output signals with excellent linearity and rapid response. Robust and durable, these sensors maintain high sensitivity even at low tension levels and operate reliably across a wide temperature range without requiring temperature compensation. Our full product line offers multiple specifications, sizes, and mounting options, and is widely employed in various web‑handling equipment and production lines, including printing presses, slitting machines, rewinders, and coating machines. All of our tension sensors are based on strain‑gauge technology. Each sensor incorporates a Wheatstone bridge composed of four 350‑ohm strain gauges, significantly enhancing measurement accuracy and linearity—making them the ideal choice for high‑speed, high‑precision tension measurement.
