PS-21RWP Series is a machine that ejects the all bad preforms by inspecting the entire surface of it, the Inspected surface area includes Neck of preform, and this is possible with our specialized design structures like 3 wheels rotary type mechanical structure and Mirror tracking system.

For the Crystallized preform, certain inspections are required in order to inspect contamination, hydrocarbon, bubble, and etc. which might be occurred on the Crystallizing process. The PS-21RWP Series can inspect those bad factors which can be placed on deep position of neck inner wall precisely without blind spot within 17mm. This is possible by applying P&S designed special optical lens.
In addition, the wavy problem that can be occurred on the neck finish part while process of Crystallizing with high temperature in the oven. Our machine can beyond the limitation of previous machine vision system by adopting the high repeatable inspection method through the Air flow sensor and precision control function that installed independently.
