How do WeiCheng consumables improve cutting precision?
Our consumables use precision manufacturing technology. The geometry of electrodes and nozzles is optimized to produce a more stable plasma arc, thereby improving cutting precision. Experimental data shows that using our consumables can control cutting tolerance within ±0.1mm.
How does using WeiCheng consumables reduce production costs?
Our consumables have a longer lifespan, reducing replacement frequency. For instance, our electrodes have an average lifespan 150% longer than standard products. Additionally, higher cutting speeds (about 40% increase) mean higher production efficiency, thus lowering production costs per unit.
