Stamping die parts

  • Metal stamping parts are components that are formed by pressing metal sheets into specific shapes using a press machine and molds.
  • Application: Automobile bodies, frames, fuel tanks, appliance shells, structural components of electronic devices, kitchenware, hardware accessories, etc.
  • It can be found in almost every industrial field.

    The main feature of Stamping die parts:

    • During the pressing process, the surface of the material is not damaged, resulting in good surface quality.
    • The appearance is smooth and beautiful, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatments.
    • The pressing parts have high dimensional accuracy.
    • The dimensions of the same die are uniform and have good interchangeability.
    • They can meet general assembly and usage requirements without further mechanical processing.
    • The pressing parts are manufactured by pressing under the premise of consuming little material.
    • The parts are lightweight, have good rigidity, and the internal structure of the metal after plastic deformation improves the strength of the pressing parts.

     

    • The metal stamping parts steps: design preparation, stamping processing, post-processing and inspection packaging.
    • The specific steps may be adjusted according to the complexity of the product.
    Step Specification
    stage of preparation First, design the product drawings and determine the materials (such as stainless steel, aluminum alloy, etc.),

    Then cut the sheets to the appropriate size,

    And at the same time manufacture or debug the special molds.
    Processing of stamping die It mainly consists of two major processes:

    The separation process (such as blanking, punching, trimming, etc., which separates the material along the contour line)

    And the forming process (such as bending, deep drawing, flanging, bulging, etc., which causes the material to undergo plastic deformation without being damaged).

    Simple parts can use single-process dies, while complex curved surface parts require progressive dies or compound dies to form multiple processes at once.
    After treatment After the pressing process, remove burrs, clean and degrease,

    Then perform surface treatment according to requirements (such as polishing, electroplating, anodizing, sandblasting, etc.),

    Finally inspect the dimensional accuracy and appearance quality, and if qualified, pack and store in the warehouse.

    Die casting main feature: Die casting is a metal casting process that involves applying high pressure to molten metal within a mold. The main difference of die casting from other casting methods lies in the high pressure and high speed. Die-cast parts: complex shapes, thin walls, high precision, and a smooth surface with high dimensional consistency. The molds are typically made from stronger alloys, and this process is somewhat similar to injection molding. Which materials are suitable for die casting? Most die-cast parts are quite rare, but it is still feasible. Based on the different metal materials and applications, die castings can be classified as copper die castings, zinc die castings, aluminum die castings, etc. Used for die casting mainly material: zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys. The more special die-casting metals: ZAMAK, aluminum-zinc alloys, And the standards of the American Aluminum Association: AA380, AA384, AA386, AA390, and AZ91D magnesium. The advantages and shortcoming of die-casting: Advantages the castings have excellent dimensional accuracy. Shortcoming The main drawback of die casting is its high cost. The equipment for die casting, as well as the molds and related components, are relatively expensive compared to other casting methods. Therefore, it is more economical to produce a large quantity of parts when manufacturing die castings. The processing of die-cast parts mainly steps: Mold preparation, filling, injection, sand removal and post-treatment. Step Specification Mold Preparation During the preparation process, a lubricant needs to be sprayed into the mold cavity. The lubricant not only helps control the temperature of the mold but also facilitates the removal of the castings. Filling and Injection After closing the mold, high pressure is used to inject the molten metal into the mold. The pressure range is approximately between 10 and 175 megapascals. Once the molten metal is fully filled, the pressure will remain constant until the casting solidifies. Sand removal The pusher rod removes all the castings and separates the residues, including the mold opening, risers, gates, and burrs. This process is usually accomplished by pressing the castings through a specially designed finishing mold; Other methods include sawing and grinding. Post-processing During the production process of die-cast parts, problems such as bubbles and burrs may occur, And there may also be residual mold sand and oxide scale. Therefore, after the die-cast parts are manufactured, post-processing work needs to be carried out, including grinding, polishing, spraying, electroplating and other processes. The purpose is to make the surface of the die-cast parts more beautiful, while improving their corrosion resistance and mechanical properties.
