Resumo(s)
The injection of light alloys is an activity that requires a high effort on the
part of Engineering to maintain its competitiveness. Due to the
temperatures used, the wear of the components connected to this
manufacturing process is quite intense, requiring a constant updating
effort. This work was developed with a view to solving problems related to
the excessive wear of injection nozzles used in the die casting process, and
corresponding electrical resistances, with a view to increase its lifetime
and improve the competitiveness of the process in the injection of low-cost
parts in zamak for the automotive industry. To study and solve the
problems of premature wear of the injection nozzles, the action-research
method was used, which, through several iterations, allowed to arrive at
an improved design of the nozzle, as well as the corresponding electrical
resistance, thus increasing the life span of these components, also
improving safety around the process and generating knowledge that can be
transferable to other similar situations.
