Separation Drums serve the spatial separation of pieces of different sizes - especially the separation of injection-moulded pieces from sprues in plastic finishing or in the die-casting industry.
Depending on the task, various devices and diameters are available to achieve an ideal separation result.
Separation Drums can be used directly behind the production machine for inline separation.
Because of your large throughput, however, they are often used in combination with a feed belt as central separation stations. Thus pieces from different production machines are separated in batches.
We are glad to run trial separations for you in our pilot plant and document them with videos. Thus we can guarantee you a separation result to be achieved.
Often copied, never equalled. This MTF discovery sets the benchmark for separation drums. The planet-central adjustment in combination with the counter-running roller pairs is unique.
Separable goods with the same height but different surface areas can be perfectly separated in a perforated drum. The design of the hole shape, size and distribution as well as the choice of materials for the drum cage, etc., always depend on the task-specific basis of the pieces to be separated.
Whenever pieces can "wander" through the separation gaps of roller separation drums or perforated drums, hedgehog drums offer a solution. The sleeve pipes welded to the outside of the hole cage reliably provide an interlock-free and secure separation result.
Pieces that are still connected to the sprue after removal from the form from the tool must next be sloughed before the actual separation process can begin. MTF Technik installs sloughing drums for this purpose. This uses a sloughing medium (e.g., hardwood, plastic, steel rollers, etc.) that is placed free in the drum cage and is carried around with the parts and sprues. The variable turning direction of the drum cage ensures that the sloughing medium constantly falls against the pieces and breaks the connection to the sprue.
After the patents for the separation drums with individual adjustment as well as the planet-central adjustment mechanism, MTF Technik envisions a further novelty with the rectangle drum, which is already patent-pending. The rectangle drum uses separation vents opened by an innovative mechanism defined in the upper area of the drum.
Especially large separation drums with separation lengths of 1,000 or 1,200 mm, large drum diameters and steel rollers often require a reinforced base .
If multiple different pieces are produced in the manufacturing process, the separation process must accordingly have multiple steps. This can be achieved by repeated separations - e.g., in one central-adjustment separation drum with multiple settings - or in multi-stage separation drums.
For separation tasks in the clean room or in medical technology, the prevention of wear as well as the protection of the pieces plays a special role. Here MTF Technik offers a multitude of separation devices that already optimally fulfil your task in many clean room applications.
Special needs require special solutions. Surface-sensitive and hot pieces can, for example, be separated in a silicone drum.
This version - also as a rubber drum - is also suitable for the pre-deburring of Duroplast pieces. The fine Duroplast skins, which often cling to the pieces after the removal from the forms, can be perfectly pre-deburred in drums with reversible turning direction in combination with special sloughing media.
In addition to the actual separation zones between the two form rings, the intake and outlet rings of our separation drums can be used. These can be connected to perforated or hedgehog cages and thereby serve for multi-stage separation.
The drum cages of MTF separation drums are driven by a friction wheel as standard. Thus serious injuries to machine operators by the spinning cage are already prevented. However, sharp-edged pieces that come through the separation gaps can pose a safety hazard.
For these cases, MTF Technik offers safety coverings in a variety of configurations.
Especially in the die-casting industry or with the separation of harder materials in steel drums, an elevated noise level becomes an issue. In addition to sound dampening by the installation of foam-covered rollers, noise emission can also be significantly reduced with an additional sound-proofing hood.
Separation attachments are used for spatial separation of pieces with different sizes. They are especially useful in the plastics industry or in the die-casting sector for separating moulded pieces and sprues.
They are thus integrated directly into the process; i.e., the separation takes place "shot for shot". Usually a machine exit belt carries the manufactured pieces directly into the feed area of the separation attachment. So, for example, after the separation sprues can be ground directly at the production machine and returned to the production process.
Depending on the task, different configurations are available to achieve an optimal separation result.
We are glad to carry out trial separations with your parts for you in our pilot plant or provide you with loaner equipment for in-house trials at your facility.
With the use of the screw separator "MSL / MSR," the larger parts of the items to be separated are moved to the side with the help of the screw. Smaller pieces slide out between the height-adjustable outlet slide and the screw roller.
With the use of the separating roller separation attachment Type TA, pieces that are larger in surface area - mostly sprues - are carried to an output slide. The smaller pieces - mostly moulded parts - fall between the individual rollers.
All MTF separation attachments are also available as standing devices with a separate base. This makes it easier still to use them with different production machines or conveyor belts.
Place, plug in, done.
With the use of the screw separator "MSL / MSR," the larger parts of the items to be separated are moved to the side with the help of the screw. Smaller pieces slide out between the height-adjustable outlet slide and the screw roller.
With the disk separator, the longer pieces are carried over the disk rollers to the separator outlet, while the smaller pieces fall through the many available separation gaps.
In addition to separation, the devices - depending on the task - are also suited to piece isolation and piece counting. The screw queues the pieces behind one another so that they fall individually through a special counting sensor. Depending on the piece geometry, as many as 90 pieces per minute can be safely counted in this way.
Pieces to be separated are not always ones with differing sizes. It can also be necessary to separate different materials from one another or to separate good parts from bad ones.
Here, too, MTF Technik offers comprehensive know-how to solve demanding problems. The products and solutions are individually customized to the problem at hand. The projects displayed here therefore show only the smallest cross-section of the possibilities.
We are glad to examine your problem in detail and offer you individualized solution concepts.
Metal inserts are sprayed in a plastic injection moulding machine and transferred in batches into a conditioning basin. Before shipping, it must be determined with 100% accuracy that only products with inserts are sent to the customers.
Metal clips with plastic coating are to be tested. Only pieces with coated metal springs may continue to shipping. A 100% control must be assured.
