Description
Producing recycled plastic honeycomb bricks through injection molding involves careful consideration of several factors, including material selection, part and mold design, and processing parameters. An inappropriate combination of these elements can lead to defects, extended lead times, excessive scrap, and high production costs. This study explores the production of plastic honeycomb bricks using the injection molding process, emphasizing the importance of using recycled plastic to minimize environmental impact. Using the Taguchi L18 orthogonal array and Grey Relational Analysis (GRA), the study identifies the optimal and significant factors that influence the structural properties of these bricks made of recycled polypropylene. The main effect analysis revealed that the optimal factor combination for minimizing deflection and volumetric shrinkage is A2B1C1D3E1F3G2. ANOVA results indicated that reinforcement material is the most significant factor in enhancing the multi-quality characteristics of the honeycomb bricks. These findings can benefit the construction industry by improving the quality of plastic honeycomb bricks through the use of various fillers and thermoplastic reinforcements. By integrating the Taguchi method and GRA, the study optimizes the injection molding process to address multiple quality issues, with a specific focus on challenges related to brick production.
