We are pleased to announce that ZPU PROMASZ Wiesław Berezicki has successfully completed the modernization of our machinery fleet, which involved the implementation of an advanced 12 kW laser cutting machine. Thanks to this technology, we are introducing key product and process innovations into our day-to-day operations, which directly translate into the highest quality of service for our customers. Here’s what’s changing for you and what new solutions we can offer: NEW PRODUCT: Automatic, multi-head polishing line The most significant result of implementing this new production process is the addition of a completely new, technologically advanced product to our lineup: * Multi-head automatic polishing machine: The new automatic polishing line is capable of operating up to 12 heads simultaneously. * Additional processing options: The machine is equipped with integrated options for flame-texturing and pebble-blasting stone slabs. * Diversification and comprehensiveness: This is a combination of functions unique on the Polish market, allowing for the execution of the most complex processing tasks within a single production line, ensuring excellent technical parameters of the material. PROCESS INNOVATIONS: What Are the Benefits of Laser Technology for You? The use of a laser cutter radically transforms the existing process of preparing structural components for our machines, replacing traditional machining methods. For our customers, this means: * Uncompromising precision and repeatability of shapes: The laser enables extremely accurate cutting of steel, aluminum, and other metals. The structural components of our machines (including the new automatic polishing machine) fit together perfectly, ensuring longer service life, stability, and trouble-free operation. * Express order fulfillment (increased production speed): The laser’s very high cutting speed significantly reduces the production time for individual components. As a result, we are able to respond much more quickly to your needs and deliver finished equipment to the market more efficiently. * Production flexibility and customization: The new process allows us to seamlessly handle various types and thicknesses of materials. We are highly flexible—we can easily fulfill orders for machines with non-standard specifications, short production runs, or prototypes perfectly tailored to the individual needs of your facility. * Expanded design capabilities: Advanced laser technology enables us to cut highly complex geometries and patterns that were previously impossible to achieve using traditional methods. This allows us to design even more modern and ergonomic stoneworking machines. * Eco-Friendly Production (Zero Waste): Thanks to advanced algorithms for optimizing the cutting layout on sheet metal, we make maximum use of raw materials and reduce production waste. By choosing our machines, you support sustainable development and help reduce your carbon footprint. ZPU PROMASZ – We’re Committed to Industry 4.0 Combining modern laser cutting with process automation is our step toward the future.
