01 Material Analysis

Precise Control of Metal Composition (LIBS)

In the aerospace field, the composition ratios of superalloys used to manufacture aircraft engine blades require strict control. Fiber optic spectrometers can determine the content of various elements (such as nickel, chromium, titanium, etc.) in the alloy within a short time, with precision down to the ppm level. Through real-time monitoring, they ensure consistent composition for each batch of material, guaranteeing the stable performance of blades under extreme conditions like high temperature and high pressure. This enhances the reliability and safety of aero-engines.

Structural Depth Profiling of Composite Materials

Spectrometers can perform in-depth analysis of composite material structures. Taking carbon fiber composites, commonly used in automotive manufacturing, as an example, spectrometers can analyze their infrared spectra to understand the bonding condition between the carbon fiber and the resin matrix, assessing the internal structural integrity of the composite. This helps optimize the manufacturing process of composites, enhance material performance, reduce vehicle weight, and improve fuel efficiency.

02 Quality Control

Quality Inspection of Surface Coatings

Many industrial products are coated with various layers for protection, decoration, or other functions. Fiber optic spectrometers can perform multi-faceted inspection of coatings. In the inspection of coatings on electronic product casings, measuring the coating's reflection spectrum can determine its thickness, uniformity, and color consistency.

Non-Destructive Flaw Detection of Components

Non-destructive testing is crucial for critical components. Fiber optic spectrometers utilize the scattering and absorption properties of light to detect minute internal flaws in components.

In mechanical manufacturing, for important parts like engine crankshafts, spectrometers can detect internal hidden defects such as cracks and pores.

Compared to traditional inspection methods, it offers the advantages of being non-contact, fast, and accurate. It does not damage the components and enables real-time inspection on production lines, improving production efficiency and reducing the defective rate.

03 Production Process Monitoring

Real-Time Tracking of Chemical Reaction Processes

In chemical production, fiber optic spectrometers can monitor spectral changes in the reaction system in real-time, obtaining information such as substance concentration and reaction progress.

Taking polymerization reactions as an example, by monitoring the spectral signals of reactants and products at specific wavelengths, the progress of the polymerization reaction can be grasped in real-time. This allows for timely adjustment of reaction conditions (such as temperature, pressure, catalyst dosage), ensuring the reaction proceeds as expected. This improves product quality and yield while preventing safety accidents caused by runaway reactions.

Quality Assurance in 3D Printing Processes

As 3D printing technology becomes increasingly widespread in industrial manufacturing, ensuring print quality is key. Fiber optic spectrometers can monitor the melting and solidification states of materials in real-time during the 3D printing process.

By analyzing the spectral characteristics of the printing material at different stages, abnormalities during printing, such as material inhomogeneity or temperature fluctuations, can be promptly detected. This allows for adjustment of printing parameters, ensuring the precision and quality of 3D printed products, and promoting the large-scale application of 3D printing technology in the industrial field.
