Análise técnico-econômica de uma cabine de pintura: estudo de caso em uma micro empresa

Abstract

The present work deals with a Technical-Economic Analysis of a Painting Booth: Case Study in a Micro Company. The company is located in the city of Laranjeiras do Sul - PR. Its main problems are contamination by dirt coming from the air on the parts during painting, the contamination of small particles of paint that are suspended in the air spraying the ready-to-deliver parts and the imposition of inadequate conditions for carrying out activities on the worker. For an assertive analysis, painting tests were carried out, in which two were produced with the same material, measurements and painting processes, with the difference of a single variable, the environment in which the painting was performed, and then visual comparisons were made between the paintings. produced. For this, the first sample was painted in the current environment of the company and the second sample in a prototype of a paint booth with local exhaust. In order to generate an economic feasibility analysis, it was necessary to monitor the company within a period of six months, in order to collect the amounts spent on overcoming products with defects caused by not having a cabin painting. In sequence, 2 paint booth budgets were carried out in order to collect the product specifications, the usual monthly to keep in operation and what is the value of the investment to acquire. With the values collected and the minimum attractiveness rate imposed by the company owner, the time required for the return on investment is calculated, not considering a minimum attractiveness rate of 10% obtained within a period of 54 months and 1 day for the return on the money invested. With a pattern of complementing the development of the work, a technical visit is carried out to a company located in the city of Pato Branco - PR, which has a paint booth of the same make and model as the one chosen during the work developed. The technical visit was of great importance, as the owner of the metallurgical company can see and assess how the paint booth works, and how the quality of a painting done in it is. After all the development of the work, the conclusion concluded is that the quality of a painting inside a paint booth is much superior to the painting carried out in the current environment of the company, and the payback time is 54 months and 1 day, and when considering the company's sales flow, the great improvement in the final finish of the materials obtained, bringing a better choice in the market and greater trust from possible customers, is an investment in which it is worthwhile to be made, and the trend is that the return, as it was not considered an increase in the number of sales, which with a better paint finish tends to grow.
