  • Laser Welding

    Laser Welding

    Laser welding is a highly efficient and precise welding technology that utilizes a high-energy-density laser beam as a heat source. Localized heating melts the material, forming a specific molten pool and joining metal parts. Its core principles can be categorized as heat conduction welding (low power density, shallow penetration) and deep penetration welding (high power density, resulting in a "keyhole" structure and strong penetration).
  • Investment Casting

    Investment Casting

    Investment casting is a casting process in which liquid metal is poured into a ceramic mold. It is ideal for producing complex, precision steel parts.
  • Gravity Casting

    Gravity Casting

    Gravity casting, also known as permanent mold casting, is a traditional aluminum casting process used to create complex, custom aluminum parts. Unlike high-pressure die casting, this process produces cast aluminum parts by pouring liquid metal into a mold under gravity rather than high pressure. Its production efficiency is slightly lower than that of high-pressure die casting, making it more suitable for small and medium-volume production. However, parts produced by gravity die casting of aluminum exhibit excellent mechanical properties and a smooth surface finish.
  • Shielded Metal Arc Welding (SMAW)

    Shielded Metal Arc Welding (SMAW)

    Welding rods (electrodes) are the consumable materials used in shielded metal arc welding (SMAW). A welding rod is a coated metal wire made of a material similar in composition to the metal being welded. Choosing the right welding rod for each project requires consideration of many factors.
  • Forming

    Forming

    Sheet metal forming (Forming) is a process that transforms sheet metal into a desired shape through plastic deformation. Its core advantages and technical features are as follows: It is suitable for mass production of complex parts, such as automotive body parts, and achieves high-precision forming through die processing.
  • Lost wax Casting

    Lost wax Casting

    Lost wax casting, also known as investment casting, is a precision casting process that involves creating a wax pattern, which is then used to create the mold for the final steel part. This process is used to produce parts with complex shapes, high precision, and accuracy.
