The advantage of our twin blocks

Up to date machinery and CAD CAM facilities make it possible to manufacture high quality complex products with tight tolerances with a high surface finish suitable to withstand wear and or corrosion conditions.

The modification of the material can improve the life time of the part.

Reduce costs by using replaceable oval section.

The optimal housing/oval material in combination with element materials.

Double housing/oval materials

Choosing the correct Double Housing/Oval material is important to achieve the correct performance and reduce wear and corrosion.
