In today's world, the metalworking industry is highly dependent on precise and fast cutting technologies. Two important methods that are most used in this field are laser cutting and plasma cutting. Both methods appear to be used to cut all kinds of metals, but in terms of performance, accuracy, speed, cost, and the quality of the cutting surface, they have fundamental differences.
In this article, we examine the difference between laser and plasma cutting in Belfa services and explain why Belfa Industrial Group in Arak was able to provide sheet cutting services with the highest quality by combining these two technologies.
Introduction of laser cutting technology
How laser cutting works
In the laser cutting method, a focused beam of laser light is irradiated on the metal surface with a very high energy. This energy causes the material to melt or vaporize, and the auxiliary gas flow (usually nitrogen or oxygen) removes the melted material from the cutting site.
In this way, a clean, precise and damage-free cut is created around the piece.
Special features of laser cutting
- Very high accuracy of about one tenth of a millimeter
- Possibility of cutting complex and delicate designs
- Cutting smooth edges without pleats
- Minimum thermal change around the cutting
- Ability to cut all types of steel, aluminum, steel, brass and copper sheets
Introduction of plasma cutting technology
How plasma cutting works
Plasma cutting technology is based on the use of electric arc and ionized gas. In this method, the compressed gas passes through the nozzle of the device and is transformed into the plasma state (fourth state of matter) by the electric arc. This plasma is very hot (up to 25,000 degrees Celsius) and easily melts metal.
Characteristics of plasma cutting
- High speed in cutting thick sheets
- Ability to cut steel, steel, aluminum and copper
- Lower cost than laser cutting
- Suitable for large and thick industrial parts
In Belfa Industrial Group's plasma services, CNC plasma machines are used with high precision and set speed so that cutting is done in the shortest time and with acceptable quality.
The difference between laser and plasma cutting in Belfa services
1. Cutting accuracy
Comparing laser and plasma cutting, laser precision is much higher. Laser is able to produce fine and precise parts with very low tolerances, while plasma is better suited for parts with medium tolerances and thick edges. Belfa uses laser cutting for projects such as decorative and precision industrial parts, while plasma is more cost-effective for making chassis, metal frameworks and structures.
2. Cut surface quality
Laser cutting creates a completely smooth, shiny surface without the need for re-polishing. Plasma, in comparison, has a relatively rougher surface and requires final operations such as grinding or sanding. Belfa uses laser cutting services in Arak for projects that require a beautiful appearance, so that the final product is perfect in terms of surface quality.
3. The thickness of the sheet that can be cut
Plasma cutting has the ability to cut thicker sheets. While laser is ideal for thin to medium sheets (usually up to 25mm). In Belfa services, the choice between laser or plasma is made based on the thickness and material of the sheet in order to obtain the best quality and speed.
4. Cutting speed
In low thicknesses, the speed of laser cutting is higher, but in thick cuts, plasma performs faster. Belfa uses its own planning system for each type of order to balance speed and accuracy.
5. Implementation fee
In general, the cost of plasma cutting is lower than that of laser, because its equipment is simpler and it consumes less energy. However, in projects where cutting quality is of high importance, the cost of laser cutting is economically justified against high precision. Belfa Industrial Group has made it possible to choose the most cost-effective method based on customer needs by offering various tariffs.
6. Thermal accuracy and distortion
Laser beam is highly focused and produces heat only in the cutting area, so deformation and warping of the metal is very little. But in plasma cutting, heat transfer is higher and the possibility of part distortion is higher. By carefully setting parameters and using cooling systems, Belfa has minimized this problem in plasma services.
Technical comparison between laser and plasma cutting
Features: laser cutting, plasma cutting, very high precision (0.1 mm), medium (0.5 mm), surface quality, smooth and shiny, rougher and require polishing, thickness can be cut up to 25 mm to 60 mm, speed in low thickness, very fast, medium speed in high thickness, less high, higher cost, lower, very low thermal distortion, more main application of delicate and precise parts of structures and thick parts
This technical table helps you to know that in choosing between the two methods, the type of project and the material of the sheet is the determining factor.
Application of laser cutting in Belfa services
