Two-Component PU & Silicone Seal Strip Foaming Dispensing Machine / Gluing Machine —— Uses and Application Industries
✅ Core Uses of the Equipment
Specialized in on-line foaming, molding dispensing and automatic gluing of two-component PU (polyurethane) and silicone materials. Through high-precision dynamic mixing and automatic trajectory control, it casts and forms polyurethane (PU) or silicone foaming seal strips on-site at the joints of various shell products. Its core function is to achieve sealing, waterproofing, dustproofing and shock absorption for various shell products. The specific functions include:
High-level waterproofing and dustproofing (IP65–IP68), effectively blocking the intrusion of water v***r, dust and impurities to protect the safety of internal components;
Effective shock absorption and buffering, relieving the vibration impact during equipment operation or transportation and extending the service life of products;
Airtight/sound insulation sealing, reducing noise transmission and ensuring the stability of the internal environment of the equipment;
Integrated seamless structure (no joints, no falling off), with stronger sealing performance, longer service life and more beautiful appearance, replacing the drawbacks of traditional adhesive foam strips;
Supports various processes such as constant-volume foaming, micro-foaming and solid dispensing, adapting to different material characteristics and protection needs.
