We produce a wide variety of shapes.


Sunrock produces a wide assortment of shapes by either pressing or thixotropic casting. High performance presses are used with an extensive library of existing tooling. Our tooling design allows for new shapes to be made with very reasonable tooling costs. As a complement to pressing, thixotropic casting is used for complex shapes or lower volume production. We also offer a cast formulation that is completely free of clay, meaning that cast shapes are as chemically pure as the pressed parts and have similar high-temperature hot strength.
