Ultrasonic spray coating represents a new advancement in medical stopper coating (especially siliconization) technology. With exceptional uniformity, precise film thickness control, high material utilization, and excellent controllability, it produces high-quality pharmaceutical stoppers with consistent coating quality, minimal chipping risk, and compliance with the most stringent pharmaceutical safety requirements. Despite the high initial investment and specialized process development, its advantages in improving product quality, reducing long-term production costs (material savings and reduced scrap), and meeting regulatory requirements have made it increasingly popular in the high-end pharmaceutical packaging sector. It is a critical process step in ensuring the safety and ease of use of injectables.

Application Purpose:

• Lubricity: The primary purpose is to form a uniform, ultra-thin lubricating layer (typically medical silicone oil or silicone emulsion) on the surface of the stopper.
• Barrier: Certain specialized coatings can provide an additional barrier to the drug or the external environment.
• Functionality: Such coatings include antimicrobial coatings (rare and require rigorous validation).
