Dimensional Nomenclature E E D G O An In Depth Guide to Programming a New Part on the AVBIS This guide will teach you how to program preforms or single step bottles Preforms or bottles made by the following processes single step injection extrusion blow single step stretch blow all have a single parting line spanning vertically from the top of the neck finish down to the base bisecting the part into two halves This parting line is formed by the two halves of the mold coming together When measuring a standard dimension on a bottle or preform quality technicians typically make the initial measurement at or just off the parting line This measurement is said to be made AT ZERO or AT PARTING LINE Any diameter measured at this position is also known as PARTING LINE TO PARTING LINE or SEAM TO SEAM Following the initial measurement 0 quality technicians make a second measurement of the same dimension 90 from the parting line This measurement is said to be made at 90 or 90 to PL The goal for taking measurements at the parting line and then at 90 to the parting line is to 1 Detect dimensional ovality in the case of diameters 2 Inthe event of dimensional problems the measurements provide the plant tooling department with measurements that can be understood tooling departments generally work in 2 axes Performing these measurements by hand with calipers is relatively intui
