Physics and Technology: From the Traditional Forge to Photon Beams
The fundamental basis of modern metal decor is two fundamentally different material processing technologies, each of which has its own unique physical principles, advantages, and areas of application.
Metallurgy of Hot Art Forging
Hand forging remains the standard of exclusivity and monumentality. This process is based on the phenomenon of plastic deformation of metals when they are heated to forging temperatures (for steel, this is the range from 800 to 1200 degrees Celsius). The forging process compacts the metal structure, which significantly increases the mechanical strength, elasticity, and toughness of the finished product.
It is these physical characteristics that allow creating complex spatial structures. A striking example is the manufacture of winder and spiral forged stairs, where it is necessary to ensure smooth turns of railings and handrails without losing structural integrity. Every hammer blow leaves a unique mark on the surface, the so-called forging texture, which is highly valued in classic interiors. Modern Ukrainian workshops often combine such traditional methods with argon welding to create monolithic objects.
High-Precision Ablation and Metal Cutting
In contrast to the centuries-old traditions of forging, laser metal cutting represents the vanguard of industrial design. This technology uses a focused high-power beam of light that locally melts, vaporizes, or burns through the material. The process is computer-controlled, which ensures micron precision (up to 0.01 mm) and the absence of any physical contact of the cutting tool with the metal. This completely eliminates mechanical deformation of the sheet.
Leading enterprises use various types of radiation generators:
- Fiber and solid-state neodymium lasers: Generate radiation that is perfectly absorbed by ferrous and stainless steel, and aluminum, which provides an extremely high speed and purity of the cut without the formation of irregularities on the edges.
- Carbon dioxide installations: More effective for processing non-metallic materials, although high-power systems are also successfully used for cutting thick sheet steel.
- Ultraviolet systems: Provide the so-called “cold ablation”, breaking molecular bonds without significant thermal impact, which is ideal for ultra-thin materials.
Thanks to these technologies, the mass production of decorative facade panels, perforated ceilings, and mobile screens became possible.
