Redução do indice de ovalização na tampa 28mm

Abstract

Oval caps do not present good application performance in the client. Model of CAF5 1Pç 28mm Lid for its dimensional characteristics and specificities has greater sensitivity to mechanical stress causing deformation. Thus, the objective of this study was to identify points of attention during the process that can contribute to ovalization and propose improvements to reduce the incidence of deformed caps. To achieve these objectives it was carried out a mapping of the process of conformation of the cap, proposals for improvements and comparative tests between samples produced without any changes during production and samples produced with suggested improvements. Correct palletizing, enveloping the pallets and cooling the caps at the end of the line helping the crystallization of HDPE reduced the index of ovalized caps by almost 2%, the acceptable 1%. Thus, it is necessary to continue with the improvements, taking care when performing the palletization respecting the alignment of the boxes, making the enveloping of the load without causing kneading of the boxes and cooling of the caps.
