The VARIO-TEC die consists of different modules and can be designed in different combinations. The core bar is the heart of the die which is made in welded construction. The construction is unique and fitted individually for each customer. This component is very exposed to extreme wear. We ensure our core bars the best wear resistance through our in-house hard chrome plating facility. The inner shape of the brick is created by forming elements, the cores. Therefore the cores are an essential part of the quality and feasibility of the brick. ZMB Braun has many years of experience in metal processing and handling with various materials, such as ceramics and tungsten carbide.
