Mainly used to inject polyurethane (PU) glue into the edge or seal of the filter to increase the sealing and structural strength.

• Uniform glue distribution for good sealing effect.
• Adjustable injection amount and speed.
• Automated operation improves efficiency.

Uses hot melt glue to bond different parts of the filter together to ensure structural stability and sealing performance.

• Quick heating and melting to improve efficiency.
• Short processing cycle with fast curing.
• Suitable for bonding various materials.

Mixes two-component (A and B) glues in proportion for strong bonding and durability.

• Adjustable ratio of A and B glues.
• Precise dispensing to avoid leakage.
• Reduced labor costs via automation.

Applies sealant between plates to ensure tight structure and prevent leakage.

• Uniform coating for optimal sealing.
• Adjustable thickness and width.
• Automated controllable production.
