Medical Two-Component Silicone Gel Dosing System
Intelligent precision dosing and mixing system for medical-grade two-component silicone gel, automating A/B component feeding for bandage and silicone patch production.
- Servo gear pump, stable precise feed
- Patented static nozzle, pre-mix isolation
- PLC + touchscreen, intuitive operation
- Vacuum degassing, auto negative-pressure feed
- Real-time flow closed-loop control
- Wetted parts meet medical requirements
Intelligent precision mixer for medical-grade two-component silicone gel, designed for manufacturing medical products such as bandages, silicone patches and similar items. The equipment provides automatic metering, proportioning, mixing and continuous dosed feeding of two-component silicone gel A and B. Control is via PLC and an intelligent touch HMI, making operation intuitive and easy to learn.
Depending on material properties and process requirements, the equipment integrates the following functional modules:
• Liquid level monitoring with low-level alarm
• Feed line pressure monitoring with abnormal pressure alarm
• Vacuum degassing and automatic feeding under vacuum
• Real-time flow monitoring with closed-loop control
The dosing system is built on a precision servo motor driving a high-precision gear metering pump, ensuring accuracy and stability during long continuous feeding. The static mixing nozzle (patented) provides complete isolation of components A and B before mixing and uniform homogeneity after mixing. All parts in contact with the gel comply with medical material requirements.
