Medical products demand extremely high mold surface quality. We offer a range of specialized surface treatment processes: For transparent parts such as drip chambers, test tubes, and viewing windows, we provide optical-grade mirror polishing to eliminate flow marks and haze. For thin-wall or deep-cavity parts prone to sticking, we apply anti-stick or nano-coatings for easy ejection. For molds requiring frequent cleaning or exposure to corrosive disinfectants, we offer passivation or anti-corrosion coatings such as CrN or TiN, effectively extending mold life in demanding production environments. All surface treatments maintain product biocompatibility.
