Inner & Outer Combo Capping Machine

The Inner & Outer Combo Capping Machine is a specialized, fully automatic solution designed for dual capping applications where products require both an inner plug (wadding or dropper) and an outer cap (screw or snap fit). This system integrates two capping heads or mechanisms in a single linear or rotary unit to efficiently apply and secure both closures in one seamless operation.

This machine is ideal for pharmaceutical, cosmetic, and chemical industries, particularly where dropper bottles, essential oils, or child-resistant packaging is involved. It ensures high precision, consistent torque, and minimal human intervention — maximizing throughput while maintaining packaging integrity.
