Utilizing recycled PMMA as a water-based binder in powder injectionmolding (PIM) technology

Powder injection molding (PIM) is a cost-effective technique for manufacturing metal parts withintricate geometric shapes, used in automotive applications, gears, drills, and more. To facilitate theflow and plasticity of the metal powder during injection, a polymer binder is utilized, providing thenecessary viscosity for mold injection. The formulation of the polymer binder is crucial for achievinghigh-density metal parts in PIM. In this study, recycled PMMA was incorporated into the binderformulation to lower costs. Additionally, polyethylene glycol was included to enable the use of waterbasedsolvents instead of organic ones during the solvent debonding stage, thereby reducingbiological pollution and ignition risks
