Engineering-plastic selection should consider strength, heat, appearance, dimensional stability, assembly and the actual operating environment.
Different engineering plastics emphasize different properties. PA and PA66 are often considered for strength, wear or heat resistance; PC for transparency, toughness or impact resistance; ABS for processability and appearance; and PC+ABS for a balance of toughness, dimensional stability and finish.\nSelection should consider more than a resin name. Wall thickness, ribs, inserts, finishing, operating temperature and compliance requirements all affect the decision. Trial molding and sample validation may be needed to confirm shrinkage, warpage and assembly.\nRuibo can connect material input with tooling and molding validation so the decision reflects real manufacturing conditions.
