Core Accessories of PU gasket dispensing machine

Material tank

Double-walled stainless steel tanks with built-in heating and stirring devices ensure constant raw material temperature and uniform mixing, preventing crystallization and precipitation.

control system

Equipped with advanced PLC control system, the operation interface is intuitive, and multiple sets of process parameters can be stored to achieve automated production and ensure accurate and stable casting.

mixing head

The mixing head is precision machined to provide high shear and uniform mixing capabilities. The self-cleaning design effectively prevents clogging and has a service life of up to hundreds of thousands of pours, ensuring product consistency and high quality.

metering pump

The high-precision metering pump uses imported sealing and wear-resistant materials, with stable flow and accurate metering. It is suitable for long-term continuous operation and ensures that the sealing strip is foamed evenly and fully.

FAQ

What is a PU gasket dispensing machine used for?

It is used to foam and cast PU sealing gaskets in place, mainly for FIPG (Formed-In-Place Gasket) refrigerator and freezer cabinet door seals, and for air filter gasket casting in automotive and industrial filter production, where it foams a full seal around the filter element frame with no missing corners.

What does FIPG mean?

FIPG stands for Formed-In-Place Gasket — the sealing strip is dispensed and foamed directly onto the part (such as a refrigerator or freezer cabinet door) instead of being cut from a pre-made gasket, giving precise metering and stable casting performance.

What accessories come with the machine?

Core accessories include the raw material tanks, the control system, the mixing head, and the metering pumps that regulate precise dispensing of the PU material.

What is the metering accuracy of the machine?

The machine offers a metering accuracy of ±0.005 and a repeat accuracy of ±0.05mm, based on the published technical parameters.
