Abstract: The plastic industry is a very important manufacturing sector and injection
molding is a widely used forming method in that industry. The contribution of this work is
the development of a strategy to retrofit control of an injection molding machine based on
an embedded system microprocessors work on a field programmable gate
array (FPGA) device. Six types of embedded processors are included in the system: a
smart-sensor processor, a micro fuzzy logic controller, a programmable logic controller, a
system manager, an IO processor and munication processor. Temperature, pressure
and position are controlled by the proposed system and experimentation results show its
feasibility and robustness. As validation of the present work, a particular sample was
essfully injected.
