Hot Melt Adhesive Application Solutions

Saipu delivers application-based hot melt and PUR adhesive systems configured around your adhesive type, substrate, coating method, working width, production speed and automation requirements. From adhesive melting and heated fluid delivery to spraying, slot/scraper coating and bead dispensing, we integrate the right melters, heated hoses, applicators and related components into a complete, production-ready solution for consistent and efficient bonding.

Furniture and Woodworking

Typical processes: Edge banding, profile wrapping, panel lamination.

Recommended equipment: PUR melters (platen type), continuous adhesive supply systems, slot nozzles, and heated hoses.
Description: Furniture and woodworking manufacturing demand high standards for adhesive uniformity, initial tack, and continuous production capabilities in edge banding and wrapping. Saipu offers PUR melters and continuous supply systems that transport adhesive via heated hoses to slot nozzles of varying widths, ensuring precise application. This solution minimizes adhesive fluctuations, enhances edge banding consistency during high-speed production, and improves lamination quality.

Packaging

Typical processes: Carton/paper bag sealing, packaging assembly, intermittent dispensing.

Recommended equipment: Hot melt units, heated hoses, spray guns, or automatic dispensing platforms.
Description: The packaging industry requires high-speed, intermittent adhesive application to accommodate various carton and paper bag specifications. Saipu provides hot melt units, heated hoses, and automatic dispensing platforms or spray guns, supporting flexible switching between dot, bead, and intermittent application patterns. System configurations can be adjusted based on production speed, helping packaging companies reduce adhesive overflow, improve operational stability, and meet the need for rapid product changeovers.

Textile and Nonwoven

Typical processes: Textile lamination, nonwoven bonding, large-area spraying.
Recommended equipment: Spray application units, slot coating systems, continuous adhesive supply and melting equipment.
Description: Textile and nonwoven materials often require lightweight, large-area adhesive application that ensures bonding strength without causing bleed-through or compromising the material's hand-feel. Saipu configures spray units or slot coating systems—paired with continuous supply and melting equipment—to achieve uniform coverage and precise adhesive control. Suitable for continuous production of wide-format materials, this solution enhances bond strength and surface smoothness while reducing adhesive consumption per unit area.

Automotive Interiors

Typical processes: Foam lamination, fabric bonding, interior component assembly.
Recommended equipment: Spray guns, heated hoses, manual or semi-automatic adhesive guns.

Copy Description: Automotive interiors demand lightweighting, low odor, and consistent aesthetics in adhesive processes, often involving flexible materials like foam and fabric. Saipu offers spray guns and heated hoses that enable uniform, large-area spraying while minimizing thermal deformation and adhesive bleed-through. Manual or semi-automatic guns are also available to handle complex curved surfaces and spot bonding with flexibility. This comprehensive solution enhances the bonding quality of interior components and increases production flexibility.

Coating and Laminating

Typical Processes: Film coating, non-woven lamination, sheet/roll coating.
Recommended Equipment: Slot/scraper coating heads, continuous adhesive supply systems, hot-melt units.
Copy Description: Coating and lamination processes require continuous, uniform adhesive output to ensure the quality of the bond between films, non-wovens, or rolled materials. Saipu provides slot/scraper coating heads and continuous supply systems—powered by stable hot-melt units—to achieve wide-format, continuous coating. This solution effectively controls adhesive thickness and coverage uniformity, making it ideal for high-speed continuous production; it reduces downtime for adjustments and improves product consistency.

Hygiene Products

Typical Processes: Non-woven lamination, elastic material attachment, high-speed dotting/spraying.
Recommended Equipment: High-speed spray guns, dispensing units, hot-melt units, and heated hoses.
Copy Description: Hygiene product manufacturing demands high production speeds and strict standards for cleanliness, stability, and precise adhesive control. Saipu offers high-speed spray or dispensing units—integrated with hot-melt units and heated hoses—to ensure rapid, accurate adhesive application for processes such as non-woven lamination and elastic material attachment. This setup helps maintain continuous production cycles, minimizes adhesive breakage and overflow, and ensures product hygiene and aesthetic quality.

Filter Manufacturing

Typical Processes: Filter media pleat bonding, frame attachment, end-cap sealing.
Recommended Equipment: Dispensing/spraying units, heated hoses, hot-melt units.
Copy Description: In filter manufacturing, processes such as filter media pleating, frame attachment, and end-cap sealing require high precision in adhesive placement and strict control over adhesive volume. Saipu offers configurable dispensing or spraying units that integrate with hot-melt applicators and heated hoses to deliver precise, stable bonding performance. This solution enhances the structural integrity and sealing reliability of filter materials, meeting the demands for consistency and efficiency in mass production.

Product Assembly

Typical applications: Multi-variety assembly, prototype fabrication, and small-batch bonding.
Recommended equipment: Manual glue guns, dispensing platforms, heated hoses, and compact hot-melt units.
Description: Product assembly environments often involve diverse product types, small batch sizes, and frequent changeovers, requiring adhesive application equipment that is flexible and easy to adjust. Saipu provides manual glue guns, compact hot-melt units, and dispensing platforms, enabling operators to quickly modify application positioning and adhesive volume to suit changing product requirements. This setup is ideal for prototyping, small-batch production, and flexible on-site operations, helping to boost production responsiveness while ensuring high bonding quality.
