Manually Operated Polarimeter

The equipment utilizes linear polarized light to qualitatively observe and analyze the birefringence and stress within transparent products. This method allows for the visualization of stress patterns, which can be critical for quality control and material analysis. Additionally, the Senarmont compensation method is employed to achieve precise measurements of the rotating angle, glass temper number, and optical retardation and calculate the stress value of the sample. This technique involves the use of a quarter-wave plate and an analyzer to determine the phase shift caused by internal stress. This combination of qualitative and quantitative analysis ensures a comprehensive understanding of the residual stress .

PET Preform Strain Viewer

The PET Preform Strain Viewer is a specialized optical testing instrument used primarily in the quality control process of plastic manufacturing, particularly for PET preforms. It facilitates operators to observe crystallization and other common defects which are invisible under natural light. Residual stress in injection molding products can also detected. It has been widely used in the quality control of various plastic rough processing products and finished products.

PET Preform Strain Viewer


Features of PET Preform Strain Viewer


1. Visual identification of crystallization and other common defects:

The crystallization and other defects of PET preform can be visually identified. This is crucial because crystallization can affect the clarity, strength, and overall quality of the final product.

2. Proactive solutions for preform defects:

The equipment provides 12 common defect analysis chart, and puts forward improving solutions to specific defects in the production process.

3. Residual Stress Analysis:

The instrument can detect residual stress within the injection-molded products. Residual stress can lead to warping, cracking, or other structural failures in the final product. So identifying and eliminating these stress is essential for ensuring product quality.

Automatic Polarimeter

This device is used to measure the birefringence in transparent materials, which is a phenomenon where a material splits a ray of light into two rays when it passes through, each traveling at different speeds. This birefringence is often related to internal stress within the material.

The polarimeter automatically detects the retardation (the phase difference between the two rays) and the direction of the slow axis (the direction in which the light travels slower). This is typically done using image processing algorithms that analyze the patterns of light and dark fringes created by the birefringence.

The captured images are sent to a computer, which processes the data in real time. The software calculates the stress values and the orientation of the slow axis across the entire viewing field. The results are displayed on a screen, showing a real-time map of the stress distribution and the slow axis direction within the sample.

Direct Imaging Equipment

Direct Imaging Equipment represents a significant advancement in the screen printing plate-making process. Unlike traditional exposure methods that require film, it utilizes violet laser technology to expose images directly onto the printed material surface. This technology incorporates Digital Micromirror Device (DMD) core components from Texas Instruments (TI), high-power 405nm laser modules, and high-precision motion systems.

Traditional exposure process can suffer from alignment deviations and image distortions. However, this advanced equipment ensures precise alignment and high-quality image reproduction, thereby improving the overall quality of the printed materials.Meanwhile, this equipment is adaptable to various printing applications, including labels, textiles, and other materials. This versatility makes it a valuable tool across different sectors within the printing industry.
