In which industries is the New Solar PV Round Wire Machine used
The New Solar PV Round Wire Machine is a new generation of continuous precision production equipment, specifically designed for producing MBB multi main grid and 0BB non main grid photovoltaic tin plated round copper wire. This round wire is an internal interconnect conductor for N-type high-efficiency battery modules, replacing traditional flat solder strips. It can reduce the shading area, minimize the risk of battery cracking, and improve the power generation of the module. With the large-scale industrialization of TOPCon, HJT, and BC batteries, the demand for photovoltaic round wire materials is rapidly increasing. This article introduces the downstream application industry of the new photovoltaic circular wire machine, helping wire factories, new energy material procurement, and equipment selection engineers evaluate the investment direction of production lines.

What materials are mainly processed by Two High Rolling Machine
Two High Rolling Machine consists of only two working rolls on top and bottom, with a simple structure, strong rigidity, and easy maintenance. It is divided into reversible/irreversible, hot-rolled, and cold-rolled types, and is commonly used for rough rolling and intermediate rolling of billets, as well as for rolling thin strips, foils, and experimental samples. It is suitable for a wide range of materials, covering black metals, non-ferrous metals, rare metals, precious metals, and can also roll some metal composite plates and powder metallurgy billets. It is a basic rolling equipment for metallurgy, new materials, and metal deep processing industries.
