Diseño y construcción de una máquina semiautomática de inyección de plástico de 50G de capacidad para la empresa “D&J SECOIN CIA. LTDA.”

Abstract

In the present project the design and construction of a plastic injection machine with the capacity to manufacture pieces of up to 50 grams of weight for the company “D & J SECOIN CIA. LTDA.” of the city of Quito. For the development of this work has been considered the cost and size of the machine, for that reason a study of the injection methods and the form of the injection machines was carried out. This was carried out an analysis of the alternatives and with this to establish the most suitable design option. The calculations of all the mechanical parts and the selection of the elements that integrated the machine were carried out, after which performance tests were carried out to determine the feed rate, plastification temperature, injection time and cooling. There has also been a manual of operation and maintenance of the machine to provide safety to the operator and proper operation. The corresponding plans for the construction of the injection machine were elaborated.
