Die Casting: The Advantages of Being Under Pressure

Did you know the manufacturing process of die casting is largely responsible for assisting the spread of printed words throughout the world? First used for the casting of printing type in the mid-1800s, die casting manufacturing continues to literally shape the way we look at and use things around us. Used for the production of everything from faucets and door knobs to scale models and machine parts, the die casting manufacturing process produces metal items through the forcing of molten metal under high pressure into a die cavity. This pressure-packed manufacturing process offers the ability to create parts in various shapes and sizes in non-ferrous metals such as zinc, copper, aluminum, magnesium, lead, pewter and tin-based alloys.

Determining Die Casting Processes

The metals chosen for an application will determine if a die casting system uses the hot chamber die casting method or the cold chamber die casting method.

Hot Chamber Die Casting

  • Injection system within a pool
  • Furnace attached to a gooseneck
  • Molten metal pushed into the gooseneck, nozzle and die
  • Short Cycle time

Cold Chamber Die Casting

  • Molten metal moved using a ladle
  • Holding furnace attached to an unheated shot or injection cylinder
  • Molten metal shot into a die using a hydraulic piston
  • Metal held under pressure until it solidifies

Cleaning Metal Parts

From big to small and sturdy to delicate, die cast parts and powered metal materials will always require thorough parts cleaning. Because of the sheer intricacy and variety of parts possible, it’s critical to have complete cleaning systems in place. Walsh Manufacturing, a Cleveland-based company, offers parts cleaners and equipment designed to create and also clean the molds used in die casting. In order to meet the requirements for such specific parts and pieces, Walsh Manufacturing always starts a die casting consultation with a one-on-one meeting between the customer and the engineering department of Walsh.

Material Handling Methods

  1. Walking beam – methods for cooling beds, elevation changes and material transport
  2. Power and Free Conveyors – multiple tracks allow parts management flexibility for transport throughout the system

Efficient material handling methods help minimize carryover and offer increased ability to customize material handling for each application. In all applications, the manufacturing engineers at Walsh strive to offer a custom solution to a die casting need without an associated custom cost. This includes efforts to minimize finances by incorporating off-the-shelf components into all Walsh-designed equipment. This consideration translates into easy fixes and upgrades no matter how much use the equipment is subject to. Walsh Manufacturing also employs extensive record keeping designed to make maintenance and upgrades simple and efficient.
