Abstract

The efficiency of the curing process is one of the critical points in the tire manufacturing industry. One of the factors that need to be considered in curing efficiency is the low age of the bladder as an auxiliary material used for heat / thermal transfer from the curing machine to green tires during the curing process. Low bladder life will directly impact the high frequency of bladder changes, leading to lost time in the preparation and assembly of the curing machine at the processing stage. In this condition, when studied, the average life span of the bladder in 2017 was 237 times used, while the company's target in 2018 for the bladder life target was set at 450 times to support the curing process efficiency project. This study aims to analyze the potential problems that cause a low shelf life. This research uses the concept of DMAIC (Define-Measure-Analyse-Improve-Control) and Failure Mode and Effect Analysis (FMEA) to determine the main causal factors and preventive actions and to determine priority improvements based on the Risk Priority Number (RPN). The improvement results showed that bladder life could increase from 237 times to 450 times as targeted, loss of bladder change during curing could reduce 0.79%, and index bladder consumption could be reduced by 36.7% total cost savings of USD 196,576 per year.

Abstract

This research was conducted at an electronic component company located in Bekasi, Indonesia. Quality is a characteristic of this company, with the company's mission, one of which is eliminating customer claims. The application of the Six Sigma DMAIC method is expected to be used as a guideline for making durable product quality and reducing the high variation in the manufacturing process for bullet type products. This study aims to determine the variables of the factors that can affect the retention force value of bullet type terminal products, using the Taguchi method experiment. The research results with the Taguchi method experiment found that three variables affect the product retention force value, namely the largest outer diameter dimension, the most significant input diameter size dimension, and the smallest length position size dimension. After monitoring and data collection on the retention force dimension, it was found that the overall Cp process capability was 3.38, and Cpk was 1.58, so it could be said that the machine performance was excellent and stable.
