The PU-530-2C foam gasket machine is an automated two-component polyurethane dispensing system designed for formed-in-place foam gaskets (FIPFG). It delivers consistent bead width from 5 to 30mm with metering accuracy of ±0.2%. German-engineered controls ensure smooth motion, while the patented self-cleaning mixing head eliminates solvent use. Smart alarms monitor material levels, pressure, and temperature—keeping your production running without interruption.

Built-in safety & alarms:
Our mixing head is built with German engineering, combining pneumatic and fluid dynamics principles to precisely control the recirculation valve—keeping materials in optimal circulation and always ready for dispensing.
The stirrer speed is electronically controlled, while the mixing shaft features a patented design to ensure thorough and uniform material blending. To maintain stable performance during continuous operation, the mixing head is equipped with an internal water cooling circuit.
This integrated design delivers a consistent mix quality, reduces material waste, and supports long production runs without temperature fluctuations affecting the process.
The storage system consists of stainless steel 304 double-jacketed pressure tanks, each with a 40L capacity.
Smart low-level alarm – The system automatically alerts when material runs low, keeping production running smoothly without unexpected interruptions.
A-tank with automatic agitation – The polyurethane (A) component is equipped with a built-in stirrer that runs automatically. This prevents material separation during idle periods, ensuring consistent quality even after long pauses.
Heated tanks for both A and B components – Each tank features intelligent temperature control, adjustable from -15°C to +35°C. This guarantees stable material viscosity and reliable dispensing even in cold workshop environments.
Air content management for A-tank – Because polyurethane requires precise air incorporation for chemical stability, the A-tank includes an automatic air detection and injection system. Based on preset parameters, it adds and mixes air into the material without operator involvement. This keeps the PU chemistry stable and ready to use—batch after batch.
The control system was developed by a German engineering specialist specifically for polyurethane dispensing.
Key features:
The mixing head features instant nozzle closing and automatic cleaning functions. The patented high-pressure cleaning system uses four-hole turbo-charged water flow to deliver exceptional cleaning performance. This simplifies mixing head maintenance and reduces reliance on wear parts.
Built with a fully modular design, the valve body makes maintenance and cleaning remarkably simple. Even when heavily clogged, it can be disassembled, cleaned, and reassembled in under one minute—ready for continued use.

Your questions about our PU Foam Gasket Machines, answered by our experts.
A PU foam gasket machine operates through a closed-loop servo-controlled metering system. Precision servo motors paired with planetary gearboxes drive Barmag metering pumps (German-made) to deliver accurate two-component polyurethane flow. The system continuously monitors pressure to ensure uniform material output. A two‑stage supply design guarantees stable dispensing, even during long production runs.
Operators simply enter the desired output rate (in g/s) on the machine’s touchscreen interface. The control system automatically calculates the required pump speed and adjusts it in real time, eliminating guesswork and preventing pump clogging. The dynamically mixed material is then applied along a programmed path, forming a seamless foam gasket directly on the component.
Foam gasket machines are widely used across industries that require reliable sealing against dust, water, or air:
Electrical Enclosures – Sealing doors, panels, and cable entries for IP-rated cabinets.
Automotive & EV Battery – Gasketing battery pack covers and electronic controllers to meet thermal and safety standards.
HVAC & Filtration – Bonding and sealing filters, ducting, and housing units.
Lighting – Creating dust-tight seals on LED fixtures and outdoor luminaires.
Appliances – Sealing refrigerator panels, washing machine drums, and dishwasher components.
Industrial Packaging – Applying cushioning gaskets for sensitive equipment.
Any application that currently uses die-cut gaskets or manual sealant application can benefit from automated foam dispensing.
