OPTIMIZE EXTRUSION OUTCOMES WITH MEASUREMENT EXCELLENCE.
Speed and Dependability Are Key
For extrusion coating operations, on-line measurement and control, temperature controls, web monitoring, total machine control and ERP Level 4 management are key requirements. They are needed to improve coating quality and increase throughput. Users want to get the most from raw materials and realize a faster return on investment in various markets.

We have the process knowledge and local presence to understand users’ needs and provide solutions to help them deliver high-quality products, reduce scrap, achieve faster start-ups and improve production.
Honeywell is dedicated to providing superior results for our customers, beginning with on-time delivery, and professional installation and start-up. We verify peak performance of all components and ensure that both operators and managers understand the system and use it to full advantage. If needed, Honeywell can provide local service anywhere in the world to support continuing results.
Industry-Leading Solutions
Honeywell systems were engineered from the ground up to optimize film and sheet extrusion. For example, the MXProLine™ solution delivers the latest in industrial control technology with 50 years of applications experience. It utilizes an IIoT-ready open system design with industry-standard communication protocols to interface with automation and information systems, providing flexibility and access to the right information, when it’s needed.
Each system features web-accessible diagnostics and remote support capabilities for rapid service response.
Honeywell began with Measurement Excellence. From state-of-the-art sensors and scanners to advanced data acquisition and signal processing, all elements of MXProLine have been integrated for optimal measurements on extrusion processes.
Robust Scanners
MXProLine scanners are built to last
Many are still in operation after 20 - 30 years!
Every scanner includes:
- Edge-to-edge scanning with automatic edge detection
- High scan speeds
- High precision sensor position and spatial data alignment
- Profile correction for beam deflection
- Remote access to diagnostic information
options include:
- Super-clean design
- Vertical and unusual pass angles
- Hazardous (explosive) environments
- Elimination of thermal gradients in the scanner beam
Excellent Gauge Band
Visibility Narrow persistent streaks in the web can result in buildup of ridges on the winder known as gauge bands. Potential scrap losses are huge in downstream slitting operations.
The MXProLine measurements are designed for maximum cross-directional resolution of profile features to detect and prevent such losses. The superior low-noise and accurate mapping qualities of MXProLine scanners and sensors provide for significant reduction of gauge bands by automatic control or early detection and correction by the line operator.
Low-Noise Sensors
MXProLine builds on our experience with sensor design for best possible signal/noise and narrow CD footprint for exceptional resolution of cross-directional features. Our sensors are generally insensitive to composition, passline, formation and surface characteristics of the product.
Sensor Applications
Basis weight by nuclear
Basis weight by IR absorption
Basis Weight by Transmission X-Rray
Individual layers in coatings or co-extrusions by IR absorption
Direct caliper (thickness)
Thin Film IR thickness
Subtractive coat weight with Same Spot scanning
Direct coat weight by IR (reflectance or transmission) or X-ray

- Variable width actuators
- Coordination of multiple controllers and actuators
- Compensation for actuator cross¬ coupling
- Heater failure detection
- Dynamic adaptive filtering
- Nonlinear, asymmetrical deckling and shrinkage modeling
- Optional closed-loop die bolt temperature control
- Operator displays for easy mapping adjustments
Solutions for Flat Cast Film and Sheet Extrusion
- Process Optimization
- Target Adaptive Control
- Throughput Optimization
Supervisory Control
- Average Thickness
- Co-Extruder Ratio
- Target Preset
- Level 1 Controls
- Line Speeds

- Temperature Controls
Biaxially-Oriented Films Solutions
Accurate edge-to-edge measurements at both cast and film enable precise real-time mass balance to accurately map film thickness to the individual die bolts. The mass mapping is self-adjusting for any drift in speeds, density, moisture during operation.
The standard two scanner configuration provides the best closed-loop control and response to machine upsets and product changes, with most consistent CD mapping performance.
Optional for biax:
- Single scanner operation
- Closed-loop die bolt temperature control
- Heater failure detection
Extrusion Coating Solutions:
MXProLine supplements the standard extrusion controls package with features specific to the needs of extrusion coating:
- Speed change and splice controls
- Operator selectable setups for multiple dies
- Over/Under coating adjustments for mapping
- Same-spot scanning for subtractive coating measurement
- Infrared sensors for direct coating measurements
