The Control of the Production of Air Ducts for Reducing Waste and Applying (A case study of 1000 DUCT RATTANABURI COMPANY LIMITED)

Abstract

This research studies the method of air duct production control to reduce waste through studying, modifying, and applying to be able to reduce zinc scraps from the production of air ducts and to improve the production using equipment modification and application, using the remaining zinc scrap as various components of the air duct to study the possibility, and analyze the cause and solutions by comparing the data before and after the improvement of the air duct production.

           The result of the study was in accordance with the main objectives, which is studying the methods of air duct production control for reducing waste and applying and to study the causes and solutions of air duct production within the data collecting period of 3 months to achieve the objectives. Before the improvement, the total amount of zinc scrap was 19,120 kilograms or 39.89 percent, and after the improvement, the total amount of zinc scrap was 10,160 kilograms, equivalent to 21.16 percent, which can lead to the conclusion that replacing the old tools made from non-standard zinc scraps to new standardized tools, and using the zinc scraps as the air duct components can cause a reduction of the zinc scraps. The improvements of the air ducts production can reduce the zinc scrap from 39.83% to 21.16%, decreasing by 18.67%, or from 19,120 kilograms to 10,160 kilograms.
