A Comprehensive Analysis Of Sheet Metal Processing Technology: Processes, Materials, And Application Scenarios

A Comprehensive Analysis Of Sheet Metal Processing Technology: Processes, Materials, And Application Scenarios

Sheet metal processing is a comprehensive cold - working process using thin metal sheets (usually with a thickness ≤ 6mm) as raw materials. Through processing steps such as cutting, stamping, bending, and welding of the sheets, customized parts with uniform thickness are formed. Its characteristics of high processing efficiency and controllable cost make it widely used in fields such as industrial manufacturing, consumer electronics, construction engineering, and the automotive industry. I. Core Processes of Sheet Metal Processing The core process of sheet metal processing can be divided into three major stages: 1. Material Cutting The metal sheets are cut through methods such as shearing machines, laser cutting, or CNC stamping. Laser cutting technology is particularly suitable for complex structural parts and scenarios with high - precision requirements. It can process a wide range of thicknesses (e.g., from 0.5mm to 20mm) and avoids material deformation due to non - physical contact. 2. Forming Processing - Bending and Stamping: Angle forming is completed using bending machines or molds. The stamping process can mass - produce holes and concave - convex structures. - Edge Rolling and Rounding: Used for the forming of pipes and cylindrical parts, such as vent...

Comprehensive Analysis Of Curved Surface Forming Technology: Core Processes And Application Fields

Curved surface forming technology is a core method in the manufacturing industry for producing non - planar complex curved surface parts. It features high precision and high efficiency and is widely used in fields such as aerospace, automobile manufacturing, and consumer electronics. The following will elaborate on the technical principles and applicable scenarios of five mainstream curved surface forming processes. I. Curved Surface Printing Process Curved surface printing is a key technology for achieving decoration and marking on the surface of plastic or metal curved objects. Its core processes include: 1. Degreasing Treatment: Use organic solvents to clean contaminants such as mold release agents and greases remaining on the surface of the workpiece, ensuring the cleanliness of the substrate. If there is oil on the surface, it may lead to a decrease in ink adhesion or cracking. 2. Surface Pretreatment: Improve the surface wettability of the material through chemical or physical methods to enhance the bonding force between the ink and the substrate. For example, perform plasma treatment on some plastics to improve their ink affinity. 3. Ink Transfer: Use a flexible silicone head to dip ink from the intaglio and precisely emboss it onto the curved workpiece. The doctor...
