Peningkatan Produksi Plastik Injection dengan Analisis Overall Equipment Effectiveness dan Single Minute Exchange of Dies

Abstract

The automotive industry is a mainstay because it has a contribution to the national economy. To maintain existence and survive in the midst of intense competition, every industry must be able to continuously improve the quality and performance company in general. Plastic injection manufacturing companies for automotive components are experiencing a decline in machine performance. Machine performance is related to losses that occur in the company. To find out the cause of a decline in machine performance, research is carried out by identifying processes, outputs, losses that occur and taking other actions if needed. Results of OEE calculation analysis, machine 7 has the lowest performance of a total of 8 machines. Low OEE value is influenced by availability, performance, and quality, of three components, the lowest average availability value is only 90%, machine 7 OEE is 81%. Factors affecting OEE are low because the value of availability is low. After analyzing with fishbone diagram, the cause of low availability is due to machine and method factors. Improvement to machine 7 using the SMED method showed a decrease in setup time by 36%, while improvements were made by changing setup flow, replacing machine components, and purging process. Impact of improvements increased availability by 96%, performance, and quality by 99%, while machine efficiency/OEE increased by 93,98%.

Analisis Pengukuran Nilai Overall Equipment Effectiveness (OEE) Pada Mesin Rice Milling Unit (RMU) di PT. FSTJ

“…Availability Availability merupakan rasio dari operation time, dengan mengeliminasi downtime peralatan, terhadap loading time (Supriyati, 2021, sebagaimana dikutip dari Firmansyah et al, 2015 Availability =…”

“…Quality rate komponen ketiga perhitungan OEE, perbandingan jumlah produksi bersih atau yang sudah di kurangi dengan jumlah cacat dengan total produksi yang di hasilkan (Supriyati, 2021, sebagaimana dikutip dari Bhade & Hegde, 2020)…”

Analisis Faktor yang Menyebabkan Downtime pada Mesin Auto Front Wheel di Industri Otomotif

“…Berdasarkan evaluasi tahunan perusahaan ditemukan permasalahan pada mesin auto front wheel akibat downtime. Tingginya downtime pada mesin auto front wheel disebabkan oleh kegagalan fungsi pada mesin [20] [23]. Sering terjadinya downtime mesin merupakan indikasi kurang efektifnya preventive maintenance yang diterapkan perusahaan [5] [16].…”

Reducing dandori processing time using the single minute exchange of die method in swaging areas in automotive rubber components company

“…From one type of product to another type of product (Setiawan & Hasibuan, 2021). The goal to be achieved from implementing the SMED method is to try to speed up the setup time (Supriyati et al, 2021;Arifin, 2018). Most companies spend more than 20 percent of their production time for changeover (Azwir et al, 2021).…”
