Until now, used parts of automobiles necessary for the remake of automobiles have been recovered from auto repair shops. But it takes much time and cost to collect those parts because the recovery system has not been set up. Furthermore. used parts from auto junk yards have rarely been used for the remaking. This current situation will improve by adopting DISRMPA(Distribution Information System for Recovery and Management of used Parts of Automobiles) designed by the author. Auto repair shops or junk yards input the information of used parts to make a database in the system. Remaking companies use the database to find and recover used parts. The DISRMPA can help prepare stabilized ways to supply used parts.

In order to review the End-of Life Vehicle(ELV) recycling system and recycling business of dismantlers in Japan, scheme of the automobile recycling law, status of ELV recycling, exports of used cars, ELV marketing business of dismantler and upgrading of used parts net work were studied. On the other hand, field survey in details for dismantling works were conducted at West-Japan Auto Recycling Co.. Although the ELV recycling system has been operating smoothly without any noticeable trouble, recycling business is running under severe circumstance. Exports of used cars have been increasing day by day through worldwide 176 countries. Finally, reuse parts of ELV concerning innovation marketing was discussed.

현재 국내 건설기계 부품의 대부분이 수명 시간이 도래한 중고 장비가 동남아시아 등지로 재제조 되지 않고 수출되거나 폐기되고 있다. 이를 재제조함으로써 자원순환이란 관점에서의 많은 경제적 환경적 이점들을 충족하고자 하며, 선진국들과 중국도 일찍이 건설기계 부품 재제조 사업을 장려하고 있다. 재제조 사업은 부가가치가 높아 여러 국가의 유명 완성차 업체가 직접 참여하여 재제조함으로써 많은 건설 시공사와 수요처들에게 판매하고 있고, 수익성도 높아 완성차 제조 기업 중 재제조 사업으로 총 매출 중 20%를 차지할 만큼 적극적이다. 그러나 국내는 이제 2016년 건설기계 부품 재제조 협회를 창립하면서 음성적으로 재제조하여 왔던 기업을 양성화함은 물론 기반 인프라 구축을 통하여 선진 기업과의 조속히 격차를 줄여 나가고 있다. 또한 재제조에 대한 공정 기술을 개발함과 동시에 전국 인프라 구축을 통하여 산업의 활성화를 꾀하고자 건설기계 부품 산업의 발전 전략을 수립하여 본 기고에 제시하여 보았다.

The scale of repair parts market reached 0.1 billion won. Above all, it is remarkable that the automotive insurance business world is paying f3r 40 ~5o% of the whole repair cost. The repair parts consist of a genuine parts, non-genuine parts, recycling used parts. It is the recent trend that recycled parts are more popular than the genuine parts f3r repairing crashed cars due to the cost. Performance of recycled continuous velocity(CV) joints and power steering(PS) gear box as replacement parts was tested and analysed in this study. To examine the durability of the recycled parts, the replaced CV joints and PS gear box after repair were tested and analysed periodically. The results were showed that basic performance of the recycled parts was normal. However the ball cage of CV joints was more frequently damaged than genuine parts. We concluded that a test standard and amendment of related laws for recycled parts is required to get a safe and durable parts.

This study is aimed at compare and evaluate the environmental impact of End-of-Life Vehicle(ELV) on the eco-friendly technology dismantling and recycling system, using Life Cycle Assessment (LCA) method. In this study, it was analyzed for the environmental impacts of raw materials, disassemble process, recycle parts separation and waste treatment into the process of ELV treatment by greenhouse gas and resource consumption, etc. Through this study, the indoor rail type dismantling technology were recycling rate applied on the alternate system was increased by approximately 8%. As a result, it was 3 to 88% by improving the environmental impact category. In addition, the added benefit of approximately 8 - 62% in pre-market occurred through the recycling rate, improve parts reuse rate of ELV. Through the results of this study, legal compliance, improved reuse and recycling ratio, used parts market reach, enable exports has identified the need for the effort that the dissemination and diffusion of eco-friendly technology.

There are genuine parts, non-genuine parts and recycled parts which can be replaced for the repair of damaged parts of crashed cars. It is the recent trend in korea that recycled C. V joints are more popular than the genuine parts fur repairing crashed cars due to the cost. Performance of recycled C. V. joints as replacement parts was tested and analysed in this study. To examine the durability of the recycled parts, the replaced C. V joints after repair were tested and analysed periodically. The results were showed that basic performance of the recycled parts was normal. However ball cage was more frequently damaged than genuine parts. We concluded that a standard test for recycled parts is required to get a safe and durable parts.

In this paper, it was performed to protect the remanufacturing industry of domestic automobile part and grasp the latest tendency of remanufacturing industry of domestic automobile part for development of remanufacturing technology and economical support of government. Research on the present statue of the remanufacturing industry was indicated that the number of remanufacture enterprises about automobile part, the annual, the number of employee in remanufacture and the type of remanufacturing. The general problems were presented which blocked the activities of domestic automobile part. It was also presented that problem of remanufacturing technology side and quality assurance of remanufactured automobile part and found out solution.

In this study, performances of two cleaning methods were analyzed and a cleaning system was designed to develop a cleaning process of electronic components to remanufacture old laser copy machine. First, plasma cleaning as a dry cleaning method was executed to test cleaning ability. In cleaning of printed circuit board (PCB) by plasma, some damages were found near the metal parts, and considering the productivity, this method was not adequate for the cleaning of electronic components. With 4 different cleaning agents, ultrasonic cleaning tests were executed to select an optimal cleaning agent, aqueous agents showed superior cleaning performance compared to semi-aqueous and non-aqueous agents. Cleaning with aqueous cleaning agent A and 28 kHz ultrasonic frequency can be completed in 30 sec to 1 min. Finally, an ultrasonic cleaning system was constructed based on the pre-test results. Optimal cleaning conditions of 40 kHz and $50^{\circ}C$ were found in the field test. The productivity and economic efficiency in remanufacturing of laser copy machine are expected to increase by adapting developed ultrasonic cleaning system.

In this study, evaluation tests for cleaning performance of various cleaning agents and selection of optimal ultrasonic cleaning parameters were executed to develop an efficient cleaning process in remanufacturing of laser copy machine. Cleaning performance tests were executed with 8 cleaning agents (A~H) to remove the contaminants of oil-ink, toner particles, and shoe polish. Physical properties and foamability tests were also applied. For 3 types of contaminants, cleaning agent G showed superior cleaning performance compared to agent A which has being used at a remanufacturing of laser copy machine in Korea. With cleaning agents selected in pre-tests, ultrasonic cleaning tests were executed to remove real contaminants on the parts of used digital laser copy machine parts. Cleaning agent G at 28 kHz ultrasonic frequency showed faster cleaning performance compared to agent A and other frequencies. The productivity and economic efficiency in remanufacturing of laser copy machine are expected to increase by adapting agent G and 28 kHz frequency at ultrasonic cleaning process.
