Desktop Standard Diameter Glass Fiber Powder Particle Length Automated Inspection Equipment
Product Spotlights
For enterprises engaged in deep fiber processing, composite materials, and high-end filtration materials, the uniformity of fiber powder length and the distribution of the length-to-diameter ratio are core indicators determining downstream product mechanical improvement, filtration accuracy stability, and material homogenization level. They are also key prerequisites for meeting high-end customers' formulation requirements, stabilizing powdering processes, and controlling finished product defect rates.
The powder making process is the core step in fiber post-processing. Tool wear, feed speed fluctuations, and deviations in crushing process parameters can directly cause fiber powder length dispersion and length-to-diameter ratio deviation from standard ranges, ultimately affecting product grade and downstream compatibility. Therefore, being able to quickly and accurately batch measure the length, diameter, and length-to-diameter ratio data of fiber powders in bulk, and promptly adjust production processes, is a core necessity for quality control in fiber powder production.
Constantly exploring more efficient detection methods, traditional manual microscopy requires reading the length and diameter of each tube individually and then manually calculating the length-to-diameter ratio, which is extremely inefficient, with small sample sizes per batch, strong subjectivity, and large errors, making it difficult to fully reflect the true distribution of batches; Moreover, manual inspection cycles are long, process adjustments are delayed, and batch defects are easily produced, making it difficult to meet the traceability requirements for large-scale production and national standard compliance.
Based on the above situation, we have designed a fiber powder particle length distribution control solution, creating this fully automatic AI fiber powder length inspection device. With "high-precision detection as the foundation, distribution data analysis as the core, and process optimization as the goal," it provides a one-stop solution for core fiber powder length detection and process control needs, helping enterprises improve product quality and achieve cost reduction and efficiency gain.
Our equipment centers on offline high-precision batch inspection, eliminating the need for production line modifications and disruption to normal operations. Through a lightweight model of "rapid sampling — fully automated inspection — quantitative data output," enterprises can frequently inspect batch quality, compressing the anomaly detection window from "hour-level" to "minute-level," truly achieving timely problem detection and early loss stopping, achieving quality control and cost-reduction efficiency improvements at low cost.
The equipment does not require modifications to the production line and can be used simply by placing it in the quality inspection room. Through offline sampling and rapid testing, high-frequency control of fiber powder length is achieved, bringing four core changes:
1. Higher inspection efficiency: Fully automated batch identification and statistics, far surpassing manual per-stick measurement. Supports multi-sample inspection per batch, reducing length inspection cycles from "hour-level" to "minute-level," enabling rapid process adjustment feedback and significantly reducing batch defective losses.
2. More accurate data accuracy: Equipped with dual high standards for 0.01μm diameter detection and 0.1μm length detection accuracy, it automatically outputs quantitative indicators such as length distribution, diameter distribution, and length-to-diameter ratio distribution, accurately identifying dimensional anomalies caused by tool wear and process drift, and accurately capturing subtle differences invisible to the naked eye.
3. Implementation cost*** No need for production line upgrades, no disruption to production rhythm, investment far less than online testing solutions, covering all categories and specifications of fiber powders, strong adaptability, and outstanding cost-performance.
4. Better quality control management: automatic archiving of inspection data, traceability of long-term length trends for single batches and production lines, scientifically setting tool replacement and process calibration cycles, stabilizing finished product quality and reducing raw material and rework costs.
Offline rapid test solution: batch length distribution determination completed in 10 minutes
After the production line produces fiber powder, workers only need to take a small sample and prepare a simple sample to start testing on the equipment. The equipment operates fully automatically, issuing a complete length distribution inspection report in just 3 minutes. From sampling to batch quality determination, the entire process takes less than 10 minutes.
Once data shows length dispersion exceeding standards or abnormal distribution, the production line can immediately adjust powder processing parameters to intercept problems early, minimize defective product output, and lower raw material and rework losses.
