Hot Wire Bottle Cutter NXG

Presto’s Hot Wire Bottle Cutter is a widely used instrument in PET bottle industries. PET bottles are mainly used for packaging of various products such as carbonated drinks, food items and so forth. They are also used for packaging of chemical. The shape and size of the bottles is important for the better safety of the products that are packaged in the bottles. For the best shape and size, it is important to test the weight of every section of the PET bottles individually. This process is called the section weight analysis. For accurate section weight analysis, the individual sections of the PET bottles need to be cut properly and precisely without causing any deformation in the shape of the bottle. The Hot wire Bottle cutter helps in this testing procedure of the PET bottles.

The Presto’s Hot Wire Bottle cutter NXG is designed to easily cut the individual sections of the PET bottles. The capacity of the bottles that can be cut using the instrument ranges from 200 ml to 2000 ml. the maximum diameter of the bottles that can be cut with the hot wire bottle cutter is 110 mm. Each section of the bottles is cut in exact dimensions and not deformation occurs in the shape and size of the bottles during the cutting. After accurate cutting of the sections, each section is weighed on a digital balance for accurate measurement of the weight of the sections. This helps in controlling the manufacturing process for better quality assurance and quality control.

Polariscope Strain Viewer

Presto offers Polariscope, a highly efficient strain viewer that helps the manufacturers in testing the quality and transparency of the products so that best quality assurance could be ensured to the customers. The working of the Presto’s Polariscope is based on the principle that any change in refractive index is due to different strain distribution and this leads to lower transparency of the material. The testing instrument offered by Polariscope comes in variety of sizes and specifications according to the requirements of the clients

Photoelasticity is a major phenomenon that occurs in PET, Preforms and Glass products. Photoelasticty means the change in the refractive index of the material when there is non-uniform strain distribution throughout the material. Photoelasticity can be a great problem for the manufacturers of PET and glass products as this is great flaw in the quality of the products.
