Smooth Turns. Seamless Seals – All in One Flow
Automated adhesive dispensing for complex geometries and critical enclosure sealing — from tight curves to long runs, ensuring uniform gaskets with no gaps, no mess. Get consistent, high-precision bead application across cabinets, chassis, and more.

Sealing Adhesive Dispensing Machines for Enclosure Protection

This machine replaces manual gasket tacking by combining on-site foam-in-place technology with smart controls to deliver waterproof, dustproof, and noise-dampening seals.

Simply load your CAD profile (or choose from built-in patterns), and the dispenser lays down a bead of reactive polyurethane that foams and cures in seconds, forming a bonded seal strip that locks onto your part.

Before each run, you set bead height, width, and machine speed to match your design; then just load the workpiece and let the system handle the rest—fully automatic, fast, and safe.

Common Enclosure Sealing Applications

Electrical & Control Cabinets

Precisely apply silicone or polyurethane along door flanges and panel seams to protect switchgear from dust ingress and condensation.
 

Server Racks & Chassis

Seal cable entry points and ventilation cutouts to maintain airflow while blocking contaminants.
 

Communication & Signal Boxes

Create reliable seals around connectors and display windows, safeguarding PCBs from corrosion and short circuits.
 

HVAC & Battery Modules

Dispense gasketing around filters, manways, and junctions, ensuring energy efficiency and safety.
 

FAQS

  • 1. How does our PU foam gasket machine work?
    加 Created with Sketch.
    形状 Created with Sketch.

    This system stores two sealant parts separately. First, Component A (polyol) is metered into a mixing chamber and kept circulating. Then, Component B (isocyanate) is added in a precise ratio—no extra stirring needed. The two liquids meet in the mixer head and instantly react, foaming into a solid polyurethane seal. Finally, the machine dispenses the fresh sealant directly onto your parts, creating a clean, bonded gasket without manual mixing or mess.

  • 2. I manufacture basic cabinet doors for electrical and distribution enclosures—will an entry-level dispenser meet my sealing needs?
    加 Created with Sketch.
    形状 Created with Sketch.
    Absolutely. Our adhesive dispensers are built to Scheugenpflug-level standards, and even the entry-level model delivers reliable waterproof and dust-proof seals on a variety of cabinets— from chassis enclosures and server racks to distribution and control panels—while keeping your investment budget-friendly.
  • 3. What sealing width and height can your PU foam gasket machine achieve?
    加 Created with Sketch.
    形状 Created with Sketch.
    Our 6th-generation dispensing machine delivers a seal width of 5–30 mm and a seal height of 3–10 mm, ideal for standard gasket profiles. The 7th-generation model expands capability to a seal width of 3–30 mm and a seal height of 2–15 mm, offering finer, more precise dispensing for demanding applications.
