Film Extrusion Quality Assurance Systems

Poor alignment, guiding or tracking problems can cause issues with the film extrusion process. This can lead to several defects, including wrinkles, baggy edges and tension issues. Blown film extrusion defects can be costly in terms of product damage and lost time. Film lines have incredibly tight tolerances — often as little as 0.002 to 0.005 inches. By establishing a permanent frame of reference for all future alignment inspections, it becomes easier to identify the cause of film extrusion problems and fix them, reducing downtime.

Using blown film inspection tools, you can quickly pick up on issues. Blown film inspection software helps identify problems and ensure alignment during unwinding and rewinding. BST web guiding systems can help detect displacement and ensure correct alignment during the flat film extrusion process, helping you detect problems early and reduce waste and product damage. With terminal web guides and edge sensors, you can detect misalignment caused by vibration, roller wear, or frame movement and fix those issues before they become a serious problem.

Our SMARTGuide system and FRAMEGuide are especially suitable for film extrusion systems with closed loops and low material stress, ensuring maximum accuracy at all times.

BST is a competent partner for material control in the extrusion process, such as in the production and processing of plastic films, but also in many other areas of application. The basis of every application is reliable and precise web guiding. Our systems are also individually tailored to the requirements of your production. Our service for you includes all project phases, from planning to implementation and user training. With our solutions, you can save raw materials and energy, reduce scrap and maintenance times, increase productivity, and ensure product quality.
