The following versions of core shooting machines are available
All core shooting machines listed can also be offered as core production centers with integrated sand processing.
Core shooting machines with belt discharge, so-called belt automatics, are among the most productive core shooting machines. They are primarily used in large-scale production in the valves, fittings and automotive industries. By fully automatically placing the manufactured cores on a conveyor belt, production can be highly automated. It is no longer necessary for the operator to remove the cores from the machine table and then restart the machine. The machine always runs at maximum productivity and the cores can be picked up by untrained personnel. Because the cores are buffered on the belt, the cores can cure for longer before being picked up manually or by a robotic system. The automatic placement of cores on a conveyor belt minimizes operator intervention, allowing one person to operate multiple machines.
In addition to pure hot boxes, cold boxes, Croning, Betaset or CO₂ machines, combination machines are also possible that can be converted to the other process after a tool change.
The special shooting valve with high shooting impulse ensures a tight core and allows fine shooting channels.
During the curing process, the shooting head moves out of the core box area to avoid hardening of the core sand in the shooting head and in the shooting nozzles. The automatic tilting head adjustment adapts effortlessly to different core box thicknesses.
The stable base frame not only ensures a torsion-resistant construction of the machine even under high clamping forces, but also includes cleaning drawers for effortless care.
In addition, the system offers the option of a core handling robot for smooth further processing or storage of the cores.
Further special features of the KLANN belt machines are:
- Mandrel pulling device to insert vertical saving mandrels into the core box
- Lateral loose part pulling device
- Core box changing aid
- Automatic tilting head adjustment
- Blow-off and release agent spray devices
- Automatic deburring device
- Base frame with cleaning drawers
- Core handling robot for further processing

The standard KLANN core shooting machines with machine table discharge of the produced cores are characterized by short cycle times and high reliability, which enables optimal productivity in core production.
Thanks to an optimized design with a small footprint, installation in confined spaces and without a foundation recess is also possible.
Compared to competing machines, the KLANN core shooting machines with machine table discharge have many design advantages. For example, when gassing the core box, the shooting head is moved out of the gassing area in order to prevent the core sand from hardening in the shooting openings.
The machine table discharge is firmly connected to the machine table, so that the core box can be moved out of the machine at any height, which saves cycle time.
In addition to pure hot boxes, cold boxes, Croning, Betaset or CO₂ machines for horizontal or vertical split core boxes, combination machines are also possible that can be converted to the other process after a tool change.
Our groundbreaking technology presents a firing valve with impressive firing momentum that is characterized by exceptional efficiency. During the gassing process, the shooting head moves precisely, accompanied by a lateral loose part pulling device and a sophisticated core can changing aid. The automatic tilting head adjustment adapts effortlessly to different core box widths.
The stable base frame not only ensures a torsion-resistant construction that does not give in even under high clamping forces, but also includes cleaning drawers for effortless care. In addition, the system offers the option of a core handling robot for smooth further processing or storage of the cores.
Design details of the KLANN core shooting machines with machine table discharge:
- Special firing valve to achieve a high firing impulse
- The shooting head is moved sideways during the gassing process
- Clamping jaw height adjustment to always clamp the core boxes in the middle
- Core box changing aid
- Base frame with cleaning drawers
- Core handling robots for further processing or storage
