Dispensing sealant into sealing grooves for medical products: How to dispense sealant using silicone sealant?

Applying sealant to the sealing grooves of medical products using sealing silicone is a technology with extremely high requirements for precision, cleanliness, and process stability. It’s not simply about injecting adhesive into the groove; it’s a systematic engineering project involving material selection, equipment configuration, process control, and environmental protection.

 

1.Core Material: Choosing the Right Sealing Silicone Liquid silicone rubber (LSR) is the preferred choice for sealing medical products. Unlike traditional solid silicone (which requires pre-molding), LSR is a two-component, flowable, heat-curing material that can be directly filled into the sealing groove and cure in situ to form a sealing ring.

 

Application Requirements/Dispensing Processes:

● Precision Dispensing: Recommended equipment: High-precision adhesive dispensing machine. Key parameters/functions: Dispensing time accurate to 0.0001 seconds, provides constant air pressure output, ensuring consistent glue volume at micro-levels, unaffected by glue viscosity variations.

● Micro-dispensing: Recommended equipment: Micro-dot Needle glue dispensing Valve. Key parameters/functions: Can dispense glue dots as small as 150 µm in diameter, suitable for precision sealing grooves in micro-medical devices.
