In-house manufacturing, solvent-free cleaning and repair — including for imported machines.
Overview
The head is where metering becomes mixing. At high pressure, the components meet by impingement in a small chamber and are discharged into the mould; at the end, a piston cleans the chamber mechanically.
Sulpol manufactures its high-pressure heads and provides maintenance and repair, including for companies running imported machinery. We assess the head, the machine and the application before recommending replacement or refurbishment.
Heads 100% manufactured by Sulpol, according to the company.
Mechanical chamber cleaning, no solvent flushing.
Head refurbishment, including for imported machines.
Interface, output and actuation verified for each machine.
Applications
Listing an application does not guarantee compatibility with every material in that sector. Each case is assessed.

Next step
To recommend a configuration we need to know the product, the polyurethane system, the mix ratio (by weight or by volume), the target output and the operating mode.
