A critical measurement in the manufacture of tires is the ply balance. This is the amount of rubber above and below the cord. In this talk we will present the online measurement of tire ply balance for both textile and steel cords. A combination of x-ray and nuclear gauges can accomplish this measurement for steel cord, but terahertz is the first technology that can .
Finally, we applied a fast scanning terahertz time-domain spectrometer based on electronically controlled optical sampling and a customized reflection head for online thickness measurements in a coating line. The textile moved at a speed of 0.5 m/min, while the measurement system records terahertz pulses at a rate of 1600 traces/s.

THz is used to control the thickness of both layers of TPO roofing and detect delamination between the layers. Top layer flatness to ±0.25 mils 3s has been achieved with auto die control. Two THz sensors can be deployed to measure the total thickness and balance of both textile and steel cord tire ply. Calibration factors forTerahertz nondestructive testing technology is a new testing method, which can accurately measure the complex refractive index, thickness and other parameters of samples. Electrode coating is widely used in the field of new energy, such as battery separator, supercapacitor electrode, etc. Here, combined with the integrated supercapacitor electrode production line, .

We use equal sample sets, THz optics, and data evaluation methods for both spectrometers. On single-layer and multi-layer dielectric .
The ability to accurately measure layer thickness is critical for ensuring consistent quality, minimizing defects and reducing material usage for products such as tubing, tires, plastic bottles, adhesives and coatings. Terahertz technology provides a solution for thickness measurement that, unlike other traditional methods, is non-contact, works with both opaque and translucent . In recent years, however, terahertz time-domain spectroscopy (THz-TDS) has reached a promising technology readiness level 4,5 and has been shown to reliably measure layer thicknesses down to ∼10 µm. 6 THz-TDS systems generate and detect electromagnetic pulses of (sub-)picosecond duration, with each pulse comprising frequencies from about 100 . With the RI value, guaranteed accurate thickness measurements are obtained. This structure is set up on the scanning frame and can be run on demand or on schedule as set by the operators. Other topics discussed .

Luna's terahertz sensor-- using reflections of an emitted energy pulse -- can provide safe, fast, accurate . We present thickness measurements with millimeter and terahertz waves using frequency-modulated continuous-wave (FMCW) sensors. In contrast to terahertz time-domain spectroscopy (TDS), our FMCW systems provide a higher penetration depth and measurement rates of several kilohertz at frequency modulation bandwidths of up to 175 GHz. In order to .Principle of terahertz thickness analysis For thickness measurement using tera-hertz time domain spectroscopy (THz-TDS), advantage is taken of the fact that the impacting terahertz rays are partially reflected at material boundaries (Fig. 1, left). In the simplest case, there are two re-flections: one from the surface betweenperformance and low resistance tires increasingly using textile components, the need for tight manufacturing control of fabric cord products has become more critical.

12 Ply vs. 10 Ply Tires. The ply rating alone doesn’t tell the whole story about a tire’s strength or performance. However, a 12-ply tire is often associated with a higher load range compared to a 10-ply tire. In practice, a 12-ply tire might be designated as a Load Range “F,” while a 10-ply tire might be Load Range “E.”
