Cutting is one of the most critical phases within the manufacturing process in the structural ceramics industry. Following extrusion, the material is in a plastic state where any deviation in the cut can directly affect the final geometry of the piece, its behaviour during drying and, ultimately, its quality after firing.
In this context, industrial cutting systems must not only guarantee dimensional precision but also adapt to the production pace, minimise waste, and ensure process continuity.
According to sector data, defects resulting from imprecise cutting can represent up to 15% of rejections in ceramic lines, highlighting the importance of implementing reliable and automated cutting solutions.
At IFAMAC, we develop cutting systems specifically designed to be integrated into ceramic production lines, adapting to different configurations and production needs.
The importance of cutting in ceramic product quality
The cutting process does not only define the length of the piece, but also influences key aspects such as:
- Dimensional uniformity
- Stability during drying
- Correct kiln firing
- Mechanical strength of the final product
A minimal deviation at this stage can generate cumulative problems in subsequent stages, causing deformations, cracks, or pieces that fall outside of specifications.
Furthermore, in high-production lines, the cutting system must be capable of working in synchronisation with the extrusion, maintaining constant rates without compromising precision.
Continuous bar cutter
The continuous bar cutter is designed to work in high-capacity lines where the material flow never stops. This system allows for synchronised cuts directly on the extruded bar while in motion, adapting the cutting speed to the advancement of the material. Its main advantages include:
- Cutting without interruption of the production process
- High precision even at high speeds
- Significant increase in productivity
- Reduction of material stresses
- Adaptation to different product formats
In automated lines, this type of solution can increase production capacity by between 15% and 25% by eliminating downtime associated with cutting stops.
Horizontal and vertical stationary bar cutters
Stationary bar cutters, in both horizontal and vertical configurations, are designed for processes where maximum precision is required or where the line allows for a brief stoppage of the material to perform the cut. These systems are particularly suitable for products requiring specific geometries or more complex cuts.
The horizontal stationary bar cutter is designed to perform precise longitudinal cuts on the ceramic bar once stopped, allowing the material to be divided into different sections according to the needs of the final product.
This type of cutting is especially relevant in the manufacture of ceramic pieces with specific geometries or multi-cell configurations, where internal uniformity and dimensional precision are critical factors to guarantee the correct behaviour of the product in later phases such as drying and firing.
The vertical stationary bar cutter is designed to perform precise transverse cuts on the ceramic bar once stopped, defining the final length of each piece with a high level of accuracy. A minimal deviation at this stage can lead to stacking problems, irregular drying, or firing defects.
Benefits include:
- Maximum dimensional precision
- Clean and uniform cuts
- Adaptation to special products
- Reduction of defects in complex pieces
Synchronous side cutter
The synchronous side cutter combines precision and operational continuity, allowing cuts to be made while the material moves along the line. This system synchronises its movement with the speed of the extruded bar, performing the cut without the need to stop the process.
Cutting automation: the key to industrial efficiency
The incorporation of automated cutting systems significantly improves the overall performance of the ceramic production line.
- Reduction of human error
- Greater process repeatability
- Optimisation of production times
- Reduction of waste
- Improved operator safety
In advanced ceramic plants, cutting automation can contribute to improving overall process efficiency by more than 10–20%, especially when integrated with control and monitoring systems.
Ultimately, cutting is a decisive phase in ceramic production, where precision and synchronisation with the rest of the process make the difference between a quality product and a defective one. At IFAMAC, we develop industrial cutting solutions designed to integrate efficiently into demanding production environments.
