Equipment use:
This Stress meter It is used for quality control and quality management of PET rough processing products. It is suitable for checking the crystallization and other defects of plastic bottle preforms
 
Equipment features:
1. Crystallization and other defects can be visually identified;
2. When the preform is placed at an angle of 45 degrees in the stress meter, colored birefringence fringes at the edge of the preform can be observed, and when the preform is placed at an angle of 0 degrees or 90 degrees in the stress meter, black birefringence fringes can also be observed; In this stage, the rotation of rough products during observation is taken into account. In addition to white light, sodium light is also used to test colored preforms or complete bottles.
3. The use of PET bottle preform special polarizing stress meter (PSV-801) can not only detect bottle preforms of various colors, but also provide 12 kinds of defect analysis functions, which can analyze various conditions of bottle preforms in the production process and provide solutions. (12 kinds of color defective contrast pictures will be attached at random to better analyze PET preforms.)
4. Stress measurement requires special knowledge and testing skills, and more importantly, comprehensive knowledge and experience of PET production process, production equipment, stress properties, use requirements, stress analysis technology, etc. The determination results can be used to guide the production process or analyze the causes of defective products.

 
The above is the sharing of Dongyi Seiko, the stress gauge supplier, on "the use and characteristics of the polarizing stress gauge PSV-801 for PET plastic bottle blanks".
The glass surface stress meter is used to check the size and distribution of stress in transparent objects. It is not only widely used in optical glass, optical instruments, glass products, plastic products and other industries, but also plays an important role in the inspection of safety explosion-proof indicators of building materials, lamps, pharmaceuticals, beverages, handicrafts, and also has many applications in the fields of crystal jewelry production, geology and minerals, and materials science. At the same time, the surface stress instrument provided by Dongyi Seiko is also an ideal teaching experimental equipment for colleges and universities.
