Abstract: As the cost of ABS commonly used for injection molding of home appliances continues to rise, many home appliance enterprises begin to use PP material to replace ABS to reduce the cost. However, PP material and ABS material have differences in performance, and the impact resistance of PP is poor. The formed ABS product is directly changed into PP material, and the product is prone to damage after the drop impact. In this paper, the properties of PP material are analyzed, and the simulation and physical experiment analysis and scheme optimization are carried out to replace ABS material with PP material for molding products. The matters that should be paid attention to when replacing ABS material with PP material are illustrated.
