laser cutting Poznań

Nowadays it is difficult to imagine modern constructions and machines without precise and complex components. Technological expansion, observed in recent years, additionally makes the requirements placed on them shape at an increasingly higher level. At present, it is definitely more common to look for elements distinguished by their finesse shapes or complex cut-outs. The emergence of laser technology should be considered a response of modern science to the changing needs of the market.

Mielec - economic characteristics of the city

Mielec is located in the southeast of Poland, within the Podkarpackie Voivodeship. The region is characterized by dynamic industrial expansion. The described city, having at its disposal attractive investment areas and a wide resource of human resources, has great opportunities to develop business-like ventures. Factors influencing the relatively rapid development of this agglomeration are considered to be both the low cost of doing business, as well as transportation accessibility and proximity to foreign markets. Referring to the city's economic opportunities, the strengths of Mielec include:

• economic zones that favor investment, i.e. SEZ Euro Park Mielec and Mielec Industrial Park,
• Food industry (brewing, meat, fish, food concentrates, tobacco, confectionery, coffee and bakery),
• Significant potential existing in various sectors of the economy (as part of industry diversification),
• Competitive prices and wide availability of land for various investments,

In view of the above, it can be concluded that the favorable conditions created in Mielec for business development make entrepreneurs increasingly willing to invest in new business ventures, as well as strive to develop existing ones. In addition to the big giants in the aviation, automotive and timber spheres, a number of small or medium-sized, often family-run businesses are developing in the described area. Mielec's location close to Poland's borders with Ukraine or Slovakia means that a number of economic relations permeate the area, attracting innovative projects. The implementation of some of them requires the use of modern solutions, such as laser cutting.

Laser cutting - the essence of the process

Laser cutting is one of the most accurate and precise ways to process various materials, especially metals. A laser beam is nothing more than focused light energy having a precisely defined wavelength. As it strikes the part being cut, this energy heats up the surface it comes into contact with, so that the part is melted or vaporized in its entirety. To further improve laser cutting, so-called process gases, such as nitrogen or argon, can be used. The aforementioned gases can perform several functions, for example, they allow combustion along the edge of the cut, cause the material melted by the laser to be blown away, and allow the material melted by the laser device to vaporize in its atmosphere. In addition, the laser light can also cope with thicker parts and complex patterns or layouts, as long as the cutting machine is properly programmed. The laser device itself is a high-precision tool, so that both an extensive cutting pattern and very fine, tightly spaced parts can be obtained with its help.

Laser cutting - characteristics of the process

The process comprising laser cutting belongs to one of the phenomena classified as thermal separation. Thus, laser cutting can be characterized as a process in which the radiation of a laser beam - either continuous or pulsed - causes either melting of the cut workpiece in the cutting slot, or simultaneous melting and vaporization, or melting and burning of the cut workpiece. During contact between the laser beam and the material in question, a large part of the light energy is transferred to it. This phenomenon makes it possible to make precise cuts, which translates into the provision of very precise processing. There is no denying that numerous features have contributed to the success of lasers in industry. The most significant of these are considered to be:

• One hundred percent repeatability of the settings of the laser device, resulting in high precision of the final parts,
• susceptibility to automation,
• versatility of applications and low material losses during cutting.

Laser sheet metal cutting - fiber laser or_CO2 laser

Modern laser cutting machines, due to their use of advanced fiber optic technology, are gaining popularity in the metal processing industry. The increasingly widespread use of these lasers in the industry is due to their much higher, with respect to machines using_CO2 technology, speed and precision of the cutting performed. Fiber laser technology is often referred to as groundbreaking and revolutionary, as it has significantly influenced the entire sector not only in manufacturing, but also in metal processing. In just five years, fiber lasers (fiber lasers) reached a cutting threshold oscillating around 4kW, which took less than four times longer for_CO2 lasers. After another ten years, fiber lasers reached a power range of 10kW to 12kW, which_CO2 lasers never managed. In the ensuing years, fiber lasers have already reached power ranges exceeding 20kW and are widely used in various industries. The result of the encompassing process is the delivery of precisely made, evenly cut shapes. It is also popular to say that without a laser, it is impossible to give a component the right shape and performance characteristics.
