Spraying Machines
Die spraying machines apply release agent to the open die surfaces of a cold chamber die casting machine in a controlled manner. Depending on the process, they can also blow out residues, cool individual die zones and lubricate moving tooling areas.
The spray pattern determines distribution across the die surface
A spray tool should not flood the entire die uniformly. Different cavities, cores, slides and thermally stressed zones often require individually adapted quantities of release agent, air and cooling.
The spraying operation is integrated directly into the machine cycle
Die spraying can only begin after the die has opened and the casting has been removed. The machine must not close again until the spraying unit has left the die area and reached its confirmed safe position.
Which parameters belong to a spray recipe?
The appropriate spraying programme depends on the die, alloy, component, die temperature, cycle and release agent. The settings should therefore be stored reproducibly and adapted to the individual production process.
Which types of die spraying machines may be suitable?
The appropriate configuration depends on die size, required freedom of movement, cycle time, spray-tool weight and the available space above or beside the die casting machine.
The spray tool is the interface to the die casting die
Even a technically suitable die spraying machine can only produce a repeatable result when the spray tool, nozzles, valves and media routing match the die contour.
What does a stable spraying process achieve?
Die spraying is only one part of the complete die casting process. A repeatable spray pattern nevertheless creates consistent conditions for the die surface, release film and die temperature.
The die spraying machine is part of the complete cold chamber automation system
Spraying movements, robot extraction, metal loading, die temperature control and machine release signals must operate without collisions and remain coordinated in time.
What to check when buying a used die spraying machine
In addition to manufacturer and year of manufacture, the actual working range, axes, control system, media supply and included scope of supply should be checked.
Inspect.
Reconfigure. The condition of the mechanical system is important. For future use, however, it is equally important that the spray tool, control system and media supply can be adapted to the new die.
Refurbishment and adaptation to a new die casting cell
Depending on their condition, used die spraying machines can be cleaned, mechanically inspected, resealed and prepared for a new application. The spraying programme and often the spray tool must then be adapted to the machine, die and release agent.
Used die spraying machines from various manufacturers
FISS Machines trades used motor-driven and pneumatic die spraying machines, spraying robots, spray tools and release-agent supply systems. Depending on availability, equipment from Wollin, Acheson, Gerlieva, Pomac, Böhmer, STP, Relbo, Maico, Rimrock and other manufacturers may be considered.
Buy used die spraying machines
FISS supports the selection of a suitable die spraying machine and the clarification of stroke, axes, spray tool, control system, media supply and scope of supply.
Dismantling, transport, technical inspection and coordination for integration into a new cold chamber die casting cell can also be taken into account.
Sell die spraying machines
FISS supports the evaluation and international marketing of individual spraying machines, complete release-agent systems, spray tools and associated automation components.
In addition to brokerage and international marketing, direct purchase by FISS may also be an option depending on the project.
