What is the most critical part of a high-pressure foaming machine? Many people may not realise it, but the answer is the mixing head. Testing the mixing head is very important for the whole machine, because only a high-quality mixing head guarantees the quality of the foamed product.
The main function of the mixing head is to mix two or three materials uniformly. The materials are mixed only in the mixing chamber for a short time, so to achieve uniform mixing in such a short period they need high kinetic energy. Reducing the nozzle aperture increases resistance and thus raises the raw material pressure.
As a key component of a complex machine, the mixing head must be well maintained to ensure safe operation and quality. Keep the mixing head in good condition to keep the equipment running well.
