Automotive Air Filters Gasket Casting Machine

The Automotive Air Filter Gasket Machine from Pioneer is a fully automatic polyurethane (PU) gasket casting machine built to pour precise, self-skinning sealing gaskets directly onto air filter frames and covers. Using a CNC-controlled trajectory system, it lays a continuous, even PU seal along any 2D or 3D groove profile, eliminating the corner glue-stacking and leakage problems common to manual gasketing. It is a proven fit for automotive air, oil and cabin filter production, and pairs well with our PU gasket dispensing machine and PU foam seal casting equipment.

Features

The machine has high degree of automation, reliable performance, convenient operation and simple maintenance. It can be cast into various shapes of polyurethane sealing strips on a plane or in a groove as required. The surface is thin self-skinning, smooth and highly elastic. Equipped with imported mechanical movement trajectory control system, it can run fully automatically according to the geometric shape required by the user. The advanced and reliable trajectory control system solves the problem of glue stacking at the corners or arcs of similar products at home and abroad.

Characteristics

Raw material tank: Three-layer stainless steel structure with stirring and automatic constant temperature.

Metering Pump: It adopts low-speed high-precision and precise transmission and display device.

Mixing Head: Automatic three-position transformation (pouring, reflow, cleaning) will not lead and lag. After the work is completed, the pneumatic shift program-controlled automatic cleaning.

Worktable: The mold is positioned on the automatically controlled universal worktable, which is controlled by imported mechanical movement and servo motor, so as to ensure balanced movement, no noise, high precision and long service life.

Control System: Digital display and automatic control of temperature, pressure, number of revolutions and pouring amount. Using man-machine dialogue interface, using advanced and reliable CNC2000 programming, programming is simple and clear, and real-time verification, simulation, monitoring.

Applications

An air filter gasket machine of this type is used wherever a filter element needs a bonded, leak-tight polyurethane seal. Typical output includes engine air filter gaskets, cabin (HVAC) filter seals, oil and fuel filter end-caps, and industrial dust and HEPA filter frames. Because the PU seal is cast in place and self-skinning, it bonds directly to metal, plastic or paper-frame filters without a separate adhesive step, giving a consistent compression set and a clean fit into the housing. The same casting platform also handles related car air filter gasket pad casting work, so a single machine can cover a full family of automotive filter models.

FAQ

What materials does the air filter gasket machine use? It processes two-component polyurethane (polyol and isocyanate), metered and mixed on-machine to form a self-skinning foam or elastomer seal. Formulation is matched to the required hardness and compression set of your filter gasket.

Can it cast gaskets on both 2D and 3D filter frames? Yes. The CNC trajectory control follows any programmed groove profile, so flat frames and stepped or contoured 3D covers are handled with the same equipment.

How is glue-stacking at corners avoided? The servo-driven trajectory system varies pour speed through corners and arcs, keeping the PU bead cross-section even and eliminating the build-up seen with manual or fixed-speed gasketing.
