[Manufacturing Example] Asthma Treatment Inhaler

Introducing a case of mass production of an asthma treatment inhaler using two-color molding with a special hook and hinge structure!

We received an inquiry from a major Taiwanese medical device brand manufacturer regarding the development and mass production of a spray-type inhaler for asthma patients. The cap components require high waterproof performance (IP58) and durability, with the main challenges being ease of use and reliability ensured by a unique hook and hinge mechanism. Strict requirements were also imposed on the speed of mass production startup and cost competitiveness. The annual production quantity is between 30,000 and 50,000 units, with a defect rate target of 1 in 5,000. The mold manufacturing period is 45 to 60 days, and the mass production period is 1.5 years. 【Technical Challenges】 ■ Ensuring waterproof performance: Achieving IP58 level waterproof performance for the cap components while maintaining mass production stability. ■ Complex structure molding: Accurately reproducing the special hook and hinge design through two-color molding (TPU on PC) and minimizing the assembly process. ■ Balancing quality and cost: Maintaining a high defect rate target (1 in 5,000) while ensuring cost competitiveness. ■ Speed of mass production startup: Rapid transition to mass production in line with the brand manufacturer's market launch schedule (mold manufacturing takes 45 to 60 days). *For more details, please download the PDF or feel free to contact us.
