Feature Batts, Plates, Tiles and Shelves
A flat, rigid product which carries and supports ware as it passes through the kiln or furnace.
Comes with a range of additional features specifically designed for your application, including holes, grooves, recesses and more.
Batts can both be cast and pressed.
General Overview
Feature batts, plates, tiles and shelves are used to support ware in the kilns and furnaces during firing and heat treatment. They can come with a range of features which cut into the batt (such as holes, slots, or recesses) or which slightly protrude out of the batt surface (such as grooves or pads). They can also be manufacturers to specific shapes, allowing them to support specific products during the firing process. They are useful in a range of industries, such as powder metallurgy.
Perforated batts (batts with many holes through them) are often used to reduce weight or improve heat transfer during firing. Recessed batts (batts with recesses carved into them) can locate product on the batt, standardising product placement and preventing movement. Cast batts are smoother and harder than traditional batts, resisting abrasion from kiln rollers and reducing the production of kiln dirt. These features are often bespoke and built around the customer’s specific requirements.
