Boston Valley Terra Cotta is the only ceramic manufacturer in the world utilizing 4 different forming methods in the manufacture of our architectural terra cotta products. These different processes give us the flexibility to create everything from flat TerraClad® rain screen panels to balusters for restoration of a Juliet balcony, all under one roof. When approached with a design, Boston Valley will consider the size, shape, ornamentation, finish, and individual piece quantity and select the best process for manufacture. Frequently, several of the processes below will be used on one project.
The RAM press is a hydraulic press originally used as a forming method in the porcelain industry. Pieces made with this forming method are not generally as sculptural as those made by hand pressing, however like hand pressing, this forming method does not allow for undercuts to be included in the die. The RAM die is a two part die made at Boston Valley to the approved shop drawing in the model and mold shop. A clay slug is placed on the die and hydraulically pressed into the form. Air forces water in the plaster die to the surface, releasing the piece from the mold.
