The HHPS® process is a process developed in-house and adapted to our production process to achieve high quality surface finishes.
This process is based on a series of techniques through which we achieve values of less than Ra 1 μm on all hydraulic surfaces.

If you work with high efficiency pumps, then this process is ideal for you. Get the most out of your equipment.
The larger the part and equipment size, the higher the operating costs. This is where our customers get the best returns from the process.
Due to the characteristics of this type of equipment, the parts that have undergone this process are perfectly adapted to their operation, optimising their performance.
HHPS® is an own process developed by FREEZE CAST.
Over the years, the technologies available from European and American manufacturers specialised in surface finishing have been studied. In the end, FREEZE CAST developed an in-house technology that allows us to achieve the best surface quality on all internal surfaces of our customers’ parts.
The HHPS® process is the result of this technological development which aims to improve hydraulic parts.
