Extrusion tools for brick products

The extrusion process is a central part of brick making where raw materials, including clay or concrete, are pressed through a mold to create bricks of the desired shape and size. Extrusion tools are designed to handle this high pressure and ensure a smooth and consistent production flow.

High abrasive impact of the mass to be extruded makes considerable problems for brick manufacturers due to high tool wear and frequent production stops, which cause difficulties in maintaining the required dimensions defined by standards. By increasing the wall thickness and product dimensions, a high percentage of the extruded mass is irretrievably lost, causing the higher energy demand in drying and firing processes.

The solution to this problem was sought by manufacturing wear elements made of steel, hard chromed metal or carbide.

The chrome-plated parts did not give optimal results and the carbide parts had no success in wider commercial use due to the high price of them.

Optimal design over the past 25 years are the manufacturing elements from high-quality oxide ceramics, which can be compared with carbide in terms of service life, but it is significantly cheaper.

Advantages of ceramic extrusion tools:

1. Durability: Technical ceramics are known for their excellent durability and impact resistance. Extrusion tools must be subjected to significant stress at high pressure and wear during long production cycles. Ceramic components can maintain their performance over time, minimizing the need for frequent maintenance or replacement.
2. High temperature resistance: The extrusion process often involves high temperatures, and ceramic tools can withstand this without deforming or losing their structure. This is critical to ensure that the bricks do not deform during production.
3. Wear resistance: Ceramic extrusion tools have a smooth and hard surface that reduces friction between the raw material and the tool. This makes it possible to extrude bricks with sharp edges and details, which leads to a better quality of the finished products.
4. Chemical stability: Ceramic materials are resistant to chemicals and corrosion. This property is valuable because some brick pipes may contain chemicals that can adversely affect other materials.
5. Versatility: Technical ceramics can be customized to meet different needs in the brick industry. The tools can be designed to create different types of bricks and brick products with precision and accuracy.

The application of these tools is not yet exceeded worldwide and our designers with extensive experience help brick manufacturers every day to solve certain details and increase productivity and quality.
