POPULAR CUSTOMIZED CATEGORIES

  • Die Casting
  • Gravity Casting

Die Casting

Core Principle: Under high pressure, molten metal is injected at high speed and pressure into the cavity ofa metal mold; the liquid metal rapidly cools, solidifies, and takes shape

 

Common Applications: Automobile, Telecommunications, Electric Motors, Robotics, Home Appliances, etc.

 

Suitable Applications: High precision, complex geometries, mass production, and lightweighting

  • Transfer Case Housing

    Transfer Case Housing

    This component is an automotive transmission housing (or gearbox housing)

    • Customization
    • 13.323kg/Customization
  • Transmission Housing

    Transmission Housing

    This component is an automotive transmission housing, a core structural element of the vehicle's powertrain system.

    • Customization
    • 10.475kg/Customization

Gravity Casting

Core Principle: Relying on the self-weight of the molten metal, it naturally flows into the cavity of a preheated metal mold to solidify and take shape; the process is relatively simple.

 

Common Applications: Sports and Wellness, Automotive Components, Electric Bicycles, New Energy Motors, etc.

 

Suitable Applications: High toughness, medium-to-large dimensions, multi-material compatibility, and small-to-medium batch production.
