Metal Loaders
Metal loaders transfer a defined quantity of molten metal from a holding or dosing furnace to the shot sleeve of a cold chamber die casting machine. The objective is a repeatable metal quantity, a controlled transfer path and reliable coordination with the machine cycle.
The path of the molten metal to the shot sleeve
Several coordinated movements take place between collecting and transferring the metal. A short, repeatable route supports a stable process and reduces unnecessary waiting periods within the die casting cell.
Linear or rotary?
Metal loaders differ in their type of movement. The suitable design depends on the positions of the furnace and shot sleeve, the available working space and the required movement profile.
Linear metal loaders move the ladle along a guided travel path between the furnace and shot sleeve. They can be particularly suitable when the collection and transfer positions are located directly opposite one another.
Rotary metal loaders guide the ladle between the collection and pouring positions using a rotating movement. This can create a compact, curved working area.
Which parameters define the dosing cycle?
A used metal loader should not be selected solely by manufacturer and year of manufacture. Its suitability depends on the metal quantity, movement profile, machine assignment and available interfaces.
Why a repeatable metal quantity matters
The metal loader creates a defined starting condition for every shot. Variations can affect the machine sequence and overall process stability.
The metal loader operates in time with the complete cold chamber die casting cell
Metal loading, die spraying, die temperature control, casting extraction and machine movements must be coordinated in time. The metal loader is therefore not an isolated peripheral unit, but part of the cell control system.
Metal loading as part of die casting automation
When selecting a unit, it should be checked how the metal loader will be connected to the furnace, die casting machine and other automation components.
What to check when buying a used metal loader
In addition to manufacturer, year and design, the mechanical system, ladle equipment, control system, actual working range and included scope of supply should be checked.
Refurbish.
Integrate. The technical condition and adaptability to the new cell determine the actual value of a used unit.
Technical inspection and adaptation
Depending on their condition, used metal loaders can be cleaned, technically inspected, mechanically refurbished and prepared for a new die casting cell. The required scope depends on the design, operating condition and intended application.
Used metal loaders from various manufacturers
FISS Machines trades used linear and rotary metal loaders for aluminium die casting systems. Depending on availability, systems from Bühler, Colosio, NTP Cibis, Tecnopresse, Gauss, Italpresse, Schmitz & Apelt, Sprötze, STP, SNAIR, Toshiba, Rimrock and other manufacturers may be considered.
Buy used metal loaders
FISS supports the selection of a suitable metal loader and the clarification of filling weight, design, working range, machine assignment, control system and scope of supply.
Dismantling, transport and technical coordination for integration into a new cold chamber die casting cell can also be taken into account.
Sell metal loaders
FISS supports the evaluation and international marketing of individual metal loaders, complete automation components and connected die casting cells.
In addition to brokerage and international marketing, direct purchase by FISS may also be an option depending on the project.
