- Abstract
This article discusses the impact of adding recycled material to injection-molded samples on their tensile strength. With the increasing use of polymeric materials, there is a growing amount of waste produced. While incorporating recycled material can help reduce waste, it can also affect the mechanical properties of the final products. The study focused on the tensile strength of samples made from different ratios of pure material and recycled material. The results indicate that the tensile strength decreases as the ratio of recycled material increases and as the distance from the ingate increases. This information is valuable for companies interested in reusing waste materials in their production processes. Another study examined the tensile properties of samples taken from a go-kart chain cover. It investigated how the location of the sample within the molded part and the composition of the injected material influenced the tensile strength. The findings revealed that as the distance from the ingate increased, the tensile strength decreased. Additionally, an increase in the proportion of return material resulted in a decrease in tensile strength. These results suggest that the addition of regranulated return material impacts the tensile strength of the samples. Further research is necessary to explore the microstructural and rheological properties of the material.
