Centrifugal Metal Casting Mini-Plant

Turnkey centrifugal metal casting mini-plant

• The centrifugal metal casting mini-plant is a compact production line designed to make pipes, bushings, rings, and blanks with a high-density structure. The process is based on pouring molten metal into a rotating mold, where centrifugal force distributes the metal evenly across the walls and produces directional solidification.

The equipment package includes: Melting section

• An induction crucible furnace for melting ferrous and non-ferrous metals, with advantages such as stable heating, precise temperature control, and high energy efficiency.
• A power unit (transformer and control cabinet) that supplies the furnace, adjusts power, and manages melting modes.
• A cooling system in the form of a closed water loop for cooling the inductor and power electronics. Centrifugal casting machine
• A horizontal machine, effective for producing long items (pipes, sleeves, bushings).
• A vertical machine, distinguished by its versatility and high precision for making rings, discs, and bearings.
• Main components: a rotating spindle or roller system, a variable-frequency drive, a metal die, a mold cooling system, a protective housing, and a PLC automation system. Tooling and molds
• Metal dies made of heat-resistant alloy steel to form the item’s geometry.
• A mold preparation process that includes preheating before pouring, applying a protective coating, and cleaning the working surface. Pouring equipment
• Pouring ladles: manual or mechanized, for transporting and pouring the melt.
• A ladle preheating system: reduces temperature loss in the melt.
• Pouring units: including guides, funnels, and automated feed systems. Auxiliary equipment
• A ventilation and gas cleaning system: removes dust and gases.
• Compressor equipment: powers the pneumatic systems.
• A hydraulic station: drives clamping and part extraction. Machining section
• Cut-off machines (band saws): used to remove machining allowances.
• Lathes: machine internal and external surfaces.
• Additional finishing: includes grinding where higher quality is required.

Quality control:

• Pyrometers: used to monitor melt temperature.
• Spectrometer: checks the chemical composition of the metal.
• Ultrasonic testing: detects internal defects.
• Measuring instruments: used to check geometric parameters.

Process parameters and features:

• Adjustable mold rotation speed depending on the item type.
• Formation of a dense structure with no shrinkage porosity.
• Displacement of non-metallic inclusions toward the inner diameter.
• Minimized gating systems.
• High mechanical properties in the finished items.
  
  Main products:
• Pipes and sleeves of various diameters and lengths.
• Bushings and plain bearings.
• Rings and blanks for further machining.
• Rollers and drums for various industrial applications.
