The fully immersed 261 kWh energy storage system, the 8 MWh containerized energy storage solution, solid-state battery storage cabinets, and the lowest-ever price of 0.58 yuan/Wh for commercial and industrial energy storage—there were plenty of highlights at the exhibition. Experts noted that the event featured a curated selection of 30 representative energy storage products, offering a glimpse into the industry’s emerging trends and technological development pathways.

Sheet metal parts are products created through sheet metal fabrication processes—processes that are indispensable in every aspect of our daily lives. These parts are manufactured using techniques such as filament power winding, laser cutting, heavy-duty machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, metal sheet bending and shaping, die forging, waterjet cutting, and advanced welding methods.

Generally speaking, a sheet metal factory's basic equipment typically includes a shear machine, CNC punching machine/laser, plasma, or waterjet cutting machines, as well as combination machines—and essential auxiliary equipment such as decoilers, levelers, deburring machines, and spot welders.

Typically, the three most important steps in a sheet metal factory are cutting, punching/shearing, and bending.

Sheet metal, sometimes also referred to as "banjin," originates from the English term "plate metal." Typically, this process involves manually or using molds to shape thin metal sheets through plastic deformation, giving them the desired form and dimensions. These pieces can then be further assembled into more complex components—such as the chimneys and iron stoves commonly found in households—or even car bodies, all of which are made from sheet metal parts.

Metal sheet processing is simply called sheet metal fabrication. Specifically, this involves using sheets of metal to create items such as chimneys, iron drums, fuel tanks and oil cans, ventilation ducts, elbows and reducers, circular and rectangular shapes, funnel-like structures, and more. The primary processes include cutting, bending with edge folding, forming through curvature, welding, riveting, and other techniques that require a solid understanding of geometry.

Sheet metal parts are thin-plate hardware components—parts that can be processed using techniques such as stamping, bending, and stretching. A general definition would be—

Parts that maintain a constant thickness during the manufacturing process. These correspond to castings, forgings, and machined parts, among others. For example, the outer metal shell of a car is a sheet metal component, and some stainless steel kitchenware also falls under the category of sheet metal parts.

Modern sheet metal processes include: filament power winding, laser cutting, heavy-duty machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, metal sheet bending and shaping, die forging, waterjet cutting, and advanced precision welding techniques.

Currently, popular 3D software such as SolidWorks, UG, Pro/E, SolidEdge, and TopSolid all include a sheet metal module. This module primarily enables users to generate the data required for sheet metal fabrication—such as flat patterns and bend lines—by editing 3D models. Additionally, it provides the necessary information for CNC punching machines, laser, plasma, and waterjet cutting machines, as well as combination machines and CNC bending machines.
