Loss Reduction in Calendering Process for Tire Production
Abstract— Tire production usually generated defect work by component depending on material properties, process setting, machine breakdown, and others. This study focuses on rework of product deviation from dimension target during starting up the machine of a tire production process, the majority causes of deformity in extrusion area, that started to study in a calendering process which produces inner liner part and has least complexity in terms of factors variation. The significant factors that impacted on product dimension in this study were Mooney viscosity and screw speed extruder needed to find the relationship. It means they are related to achieving the target of product specification such as thickness and width in mass production that has a high possibility to make loss quantity. Compound type and line speed were controlled excepted temperature and pressure setting at extruder head which were uncontrollable variables that usually are not much changed. The relationship between material properties and screw speed was determined using multiple linear regression for the width and thickness. This study is expected to provide usefulness for product dimension prediction with other compound viscosity values together with screw speed adjustment. The factors were optimized closely to get the desired target of width and thickness to minimize the defect quantity.
Index Terms— tire, manufacturing, Mooney viscosity, screw speed, optimization, regression.
