Redesign of iron for assembly cost and time reduction using DFA

Abstract

Nowadays, product development is very important to remain competitive in the market, one of which is to reduce the assembly of time and cost design. This article discusses the study of iron products on the market. Based on the problems found in the SMEs of Electronic Services, this iron has many components and complex designs that take time-consuming to assemble. Therefore, the purpose of this article is to redesign the ironing.Improvements to the design of iron products are based on the problems present in this product. This problem is obtained by distributing questionnaires to Electronic Services SMEs. The improvements are carried out using the Design for Assembly (DFA) method to evaluate the design with ease of assembly processes.This paper attempt to improve the design of ironing products according to the problems obtained from the initial questionnaire, which is to reduce the assembly time and costs using DFA.The result of these improvements is a reduction in the amount of assembly time and costs and an increase in efficiency. The actual design assembly time is 358.16 to 269.70 seconds on the proposed design. The actual design assembly cost budget is 956.81,- rupiahs, reduced to 720.50, in the proposed design. Then the actual design efficiency of 21.77% increased to 24.74%.Iron design improvements are based on problems and complaints received from the electronic services SMEs, then analysed using the DFA method. Therefore, the improvements in the design of the ironing product are present in two components, that is the back cover and the handle.
