Internal stress refers to the stress generated inside the plastic during the molding process due to uneven cooling shrinkage, molecular orientation, and other factors. This internal stress may affect the performance and service life of plastic products. Through internal stress testing, it is possible to detect whether there is an issue of internal stress concentration in plastic containers, thereby determining the quality and reliability of the product. This helps manufacturers to discover and improve production processes in a timely manner, thereby enhancing product quality.

The intelligent polarization stress meter for plastic containers is suitable for pharmaceutical companies, glass product factories, and laboratories to measure the stress values of optical glass, glass products, and other optical materials. The instrument can qualitatively and quantitatively test the internal stress of glass, and the color LCD screen automatically reads the results.

Principle of intelligent polarization stress meter for plastic containers

An instrument used to apply the principle of polarized light interference to check the internal stress of glass or the birefringence effect of crystals. Due to the sensitive color plate and the use of a 1/4 wave plate compensation method in the polarization stress meter, this instrument can not only qualitatively or quantitatively measure the optical path difference of glass based on the interference color sequence in the polarization field, but also accurately and quantitatively measure the internal stress value of glass when combined with a wall thickness gauge.

Application of intelligent polarization stress meter for plastic containers

1. Prevent product deformation and cracking

Internal stress is one of the important factors that cause deformation and cracking of plastic products. During the storage, transportation, and use of plastic containers, excessive internal stress may cause product deformation, cracking, or even rupture. Conducting internal stress testing can predict the deformation trend of products under different environmental conditions, providing a basis for product design and use, and reducing the risk of deformation and cracking.

2. Guide material selection and optimization

The magnitude and distribution of internal stress generated during the molding process of different plastic materials vary. Through internal stress testing, it can provide a basis for material selection and choose plastic materials that are more suitable for specific application needs. Meanwhile, based on the test results, manufacturers can adjust process parameters such as mold design, molding temperature, and pressure to reduce the generation of internal stress, optimize production processes, and improve production efficiency and product quality.

3. Meet industry standards and regulatory requirements

Many industries and regulations have strict requirements for the internal stress of plastic containers. Through internal stress testing, it can be ensured that the product meets relevant standards and regulatory requirements, avoiding returns, recalls, or legal disputes caused by quality issues.

4. Enhance product market competitiveness

With the intensification of market competition, consumers have increasingly high requirements for the quality and performance of plastic containers. Through internal stress testing, performance issues that may arise during the use of plastic containers, such as insufficient strength and poor weather resistance, can be identified and resolved. This helps to improve the overall performance of the product, meet market demand, and enhance its market competitiveness.

In summary, detecting the internal stress of plastic containers is of great significance for evaluating product quality, preventing deformation and cracking, guiding material selection and optimization, meeting industry standards and regulatory requirements, enhancing product market competitiveness, and promoting industry technological progress and upgrading.
