The sphere is a symbol of perfection that guides MPS in the ball manufacturing process.

Steel balls in revolution

It takes several days of machining, starting from an extruded steel wire, to achieve the perfect sphere.

The thermal treatment lends the stainless steel outstanding physical characteristics and a hardness of minimum 58 HRC. The final polishing stage leaves a mirror-finish on the surface of the ball and a precision beyond imagination.

Sub-millimetric balls

MPS specializes in the manufacturing of balls measuring less than a millimeter in diameter. The smallest sphere manufactured by MPS has a diameter of 0.150 mm.
