Abstract

Screen printing is a technique of printing graphic designs using gauze or called screens. One application of the screen printing machine is on the cup. The more beverage vendors in cup packaging like today, the more screen printing machines are needed. To meet these needs, a cup screen printing machine was made. The purpose of the study was to determine the shape and dimensions as well as the performance of the semi-automatic cup screen printing machine. The research method carried out is by designing and manufacturing a semi-automatic cup screen printing machine and testing with two different types of molding, namely 14 Oz and 16 Oz. From the results of the design and manufacture of the semi-automatic cup screen printing machine design, the length is 600 mm, the width is 400 mm and the height is 900 mm. Using an electric motor of 0.25 HP, gear box 1:60, screen length of 400 mm and width of 150 mm and using a steel frame ST 37 type L. Based on the results of tests and calculations it is known that the production capacity of the screen printing machine is 300 cups/hour and the quality production with 14 Oz molding type is 92% good, 4.67% normal, 2.6% bad while 16 Oz molding is 88% good, 7.34% normal, 4.6% bad. The electrical power consumption of the screen printing machine is 328.6 Watt and the mechanical efficiency is 54.04 %.

Abstract

In this modern era, the problem of packaging has become a part of everyday people's lives, especially in relation to food products. Cup drink MSME business actors have started using labels to market and create a special attraction for their products. At this time cup printing has begun to use machines, but the machines commonly used are only capable of printing one color and cannot print two or more colors and the price of the machines is still quite expensive. The purpose of this research is to optimize and redesign a one-color cup screen printing machine into a cup screen printing machine design that is practical and capable of printing two or more colors, to determine the power consumption of the electric motor on a two-color cup screen printing machine, and to determine the capacity and production yield of cup screen printing machines. two colours. The research method used was experimental by designing and manufacturing and testing a semi-automatic two-color screen printing device. Tests were carried out with variations in molding dimensions of 14 Oz and 16 Oz. From the results of the study it can be concluded that molding size has no effect on electric motor power, electricity consumption costs, production capacity, and screen printing quality. The dimensions of the semi-automatic two-color cup screen printing machine are 90 cm high, 60 cm wide, 30 cm thick, 374.5 watt electric motor power, electricity usage production costs Rp. 3.4 per cup, production capacity of 150 Cups/hour, and quality good screen printing reaches 92%.
