Prevent Blown-Film Defects with Thermal Imaging
Featured Product from LAND
Early warning of defects in blown film
Avoid compromising the blown film extrusion process. This critical stage of upstream production defines the composition of plastic film, whether you’re making a sturdy shopping bag or a crystal-clear electronic display. But achieving thin, flexible, and durable film is complex, and it’s easy for defects to creepin as air inflates the plastic like a balloon. Tearing and warping can cost you more than just wasted material. It can ultimately disrupt production time, increase operational costs, and risk your customer relationships. Temperature measurement is key to getting it right. To optimise a film’s thickness, optical quality, and mechanical strength, you need to better track the cooling rate from the die to the frost point, where the plastic solidifies
HIGH-DEFINITION TEMPERATURE MONITORING FOR EXTRUSION
See the full picture
Get a detailed view of your film’s surface temperature with the LSP-HD 60. This linescanner covers a range from 20 to 250 °C (68 to 482 °F), collecting 1,000 high-resolution samples per line. This detailed view means you can detect temperature changes as small as <0.5 °C. The pixels also overlap, so there are no gaps in your data. You can also monitor the temperature in real-time with scan speeds up to 150 Hz, setting an industry benchmark for process imaging. The result is ahigh-definition, heat map, allowing you to accurately identify and plot the temperature drop over time and distance. This lets you spot uneven cooling early, fine-tune process parameters, and ensure a consistent frost point.
Monitor end to end
For even greater control, pair the LSP-H60 with the SPOT+ M3-5. This IIoT-enabled pyrometer targets low temperature ranges from 0 to 500 °C (32 to 932 °F). Its compact, wireless design makes it easy to deploy throughout your extrusion line. Use the M3-5 at the die exit for initial temperature checks, or at the collapsing frame to detect late-stage anomalies. This combined approach provides complete thermal visibility. Empowering you to act fast, work more cost-effectively, and deliver the reliable quality the market demands
LSP-HD 60
Ensure product quality and better process control with this high-definition 150 Hz thermal imager for the blown film extrusion process. It can detect minute temperature changes, so you can act fast to prevent defects from developing.
SPOT+ M3-5
Monitor the extrusion process beyond the line of sight of the linescanner with the SPOT+ M3-5. This low-temperature pyrometer has a 30:1 field of view, and a 10 ms response time. It also uses internal temperature for background compensation.
