What materials and processes are supported by sheet metal processing?

　　Sheet metal processing is a metal processing technology that mainly manufactures metal products of various shapes by cutting, bending, welding and other processing techniques on metal sheets.

　　The commonly used material is metal flat plate, and the finished products mainly include shells, bases, brackets, stamping parts, etc., which are widely used in furniture, electronics, communications, construction, automobiles, machinery, chemical industry and other fields.

　　Commonly used surface treatment processes include wire drawing, plastic spraying, ordinary anodizing, silk screen printing and laser marking, etc., which can cover most sheet metal surface treatment needs.

　　1. Supported metal plates

　　The currently supported metal plates and plate thicknesses are shown in the table below. The excess parts are not supported for the time being. Please forgive me.

　　2. Supported surface treatment processes

　　The surface treatment processes currently supported include wire drawing, plastic spraying, sandblasting, ordinary anodizing, silk screen printing and laser marking.

　　⭐ Wire drawing: refers to a surface treatment process that uses a wire drawing machine and an abrasive belt to texture the surface of the workpiece to form lines on the surface of the workpiece to achieve a decorative effect.

　　⭐ Plastic spraying: refers to a surface treatment process that uses machines such as ovens to automatically spray oil and powder on the surface of hardware to make the product bright and beautiful and meet the packaging and shipping requirements.

　　⭐ Sand blasting: refers to using compressed air as power to form a high-speed jet beam to spray the spray material (copper ore, quartz sand, emery, iron sand, sea sand) at high speed onto the surface of the workpiece to be treated, so that the surface of the workpiece can be cleaned to a certain extent It is a surface treatment process that improves the mechanical properties of the product by its degree and roughness.

　　(Non-sheet metal workpiece, only for display of surface treatment effect)

　　⭐ Ordinary anodizing: refers to the process in which aluminum and its alloys form an oxide film on aluminum products (anode) under the action of applied current under the corresponding electrolyte and specific process conditions. It is a kind of enlarged aluminum alloy A surface treatment process that can be used to extend the service life of workpieces.

　　⭐ Silk screen printing: refers to a surface treatment process that uses special ink to penetrate through a special grid to form text or patterns on the surface of the workpiece, so that the printed pattern on the surface of the workpiece is clear and durable.

　　⭐Laser marking: A surface treatment process that uses high-energy-density laser to locally irradiate the surface of the workpiece to vaporize the surface material or cause a chemical reaction of color change, thereby leaving a permanent mark.

　　4. Existing processing capabilities

　　It now has laser cutting, riveting, sprouting, bending, welding and other processing technologies, which can meet the processing needs of most sheet metal workpieces. The stamping process will also be online in the near future.

　　⭐ Laser cutting: There are currently two 6000W laser cutting equipment, and the cutting parameter debugging of 0.5~6.0mm thick plates has been completed.

　　⭐ Sheet metal bending: There is one TRUMPF bending machine (high precision, high cost); one pure electric bending machine (fast, stable); one electro-hydraulic bending machine (cheap, high pressure).

　　We have commonly used upper and lower die bending dies, straight knives, curved knives, step dies, full arc molds within R3-R20, etc., which can meet a variety of bending needs.

　　⭐ Tapping and countersinking: There are currently several desktop drilling machines and electric hand drills with high efficiency and flexible processing; in the future, punch countersinking and the development of automatic countersinking tool paths will be introduced to solve the problem of lack of consistency and difficulty in ensuring quality of manual countersinking. question.

　　⭐ Pressure riveting and budding: There are two sets of pressure riveting and budding equipment and multiple sets of budding and riveting molds. It can meet the riveting and riveting processing needs of various specifications of M2.5-M10 riveting nuts, studs and screws.

　　⭐ Welding and polishing: There are currently two argon arc welding equipment, three laser welding equipment, and two secondary welding equipment. They are mainly used for the production of prototype parts and small batch parts. They have strong flexibility and meet a variety of welding needs;

　　Recently, two automatic welding equipment have been introduced, mainly used for the production of batch parts. The welding continuity and stability have been greatly improved.

　　⭐ Punch stamping: A new CNC punch machine has been added. Currently, it has conventional molds such as louvers, convex hulls, counterbore holes, and rolled ribs, as well as several sets of special molds. The punching accuracy reaches ±0.1, and the maximum plate thickness that can be processed is up to 6mm. The stamping process will be launched soon, so stay tuned!
