Molding and cutting integration
Amut, Italy, recently developed a thermoforming machine for hard food packaging. This production system (membrane coextrusion and composite thermoforming) is dedicated to the production of polypropylene (PP) cups (single-layer transparent or three-layer opaque type with recycled cores) with a production capacity of approximately 60,000/ Hours (calculated at 200 cc/cup capacity).
Viewed from the outside, the equipment is an independent working system, which mainly includes: raw material feeding and weighing feeding system.
The extrusion section includes: AMUT single-screw main extruder, EA100 series, equipped with a 35:1 length/diameter plasticizing system, equipped with oil-operated two-way screen changer, gear pump and static mixer, AMUT single screw Extruder, EA48 series, equipped with 33:1 length/diameter plasticizing system, equipped with screen changer; three-layer co-extrusion flow box with interchangeable feeder; horizontal flat die with internal melting Body adjustment rod with a maximum effective width of 900 mm.
The thermoforming section includes: equipped with in-mold synchronous forming and cutting device, and adopts the lower template tilting technology to facilitate the rapid and reliable stacking of the final product in the production of multi-cavity; the effective forming/cutting area is 780×740 mm. When using PP, it is about 22 to 23 cycles per minute, and when using PS, it is 27 to 28 times; the tilting process of the lever system is controlled by a cam fixed on four rigid columns.
The unit can also be equipped with AMUT's new edge forming machine, designed for PP products, with thermostat screw and automatic packaging machine.
Making food packaging Italy MEICO has introduced the new FC780E and FC600E thermoforming machines. The aircraft is manufactured by its Swiss sister company WMWrapé„„pingMachine. This forming/cutting/stacking/(vacuum and pressurization) thermoforming machine is all driven by an electric motor (servo motor).
Both models (including standard models) include a variety of features to process a wide range of roll-form thermoformed sheets up to 2 mm thick, including HIPS, GPPS, PET, PVC, PP, OPS and EPS.
Two independent heating boxes on the top and bottom are equipped with a proportional heating zone; the forming section and the cutting section are equipped with upper and lower independent dynamic pressure plates; the stacking device can also be equipped with counting, ejection and trimming equipment.
The advantages of the FC780E and FC600E models include: fast mechanical cycle speed, 40-times per minute for 350-micron sheet A-PET trays; low noise; low energy consumption; quick set-up because of special Mechanical design and single-board machine-specific procedures for easy mold change.
Single-station and multi-station The plastics division of QSGroup in Italy designs and manufactures a wide range of thermoforming machines, from single-station to multi-station online. Its multi-station model is designed for the refrigeration industry and is used for thermoformed linings and interior doors to increase production speed. To meet customer needs, the company has designed two sheet transfer systems: chain transfer thermoforming lines and die transfer thermoforming lines.
For single-station models, the company produces a wide range of thermoforming machines for use in a variety of industries including hygiene, automotive, electrical, and packaging. The equipment can be equipped with different heating systems, from traditional ceramic heating tubes to quartz heating tubes or halogen heating tubes to suit the processing needs of different products. It can also be equipped with a variety of auxiliary equipment, including automatic sheet loading equipment and automatic thermoformed parts unloading equipment.
In addition to the plastic sheet thermoformed single-station model, the company's plastics division also designs and manufactures roller feed thermoforming machines and single-station models for the automotive industry for laminating interior parts.
Maximum crushing and cutting force with more efficiency
Competitive cylinder systems need larger cylinders to equal the force developed by the more compact intensifier system. On the job, SanLand exclusive integral hydraulic intensifier system provides faster cycle times compared to competitive units using larger cylinders that require considerable amounts of flow to produce an equal amount of productivity; thus producing the shortest cycle time in the industry.
With the newly improved tooth configuration utilizing a high-profile center tooth and lower profile teeth on both sides of the movable jaw, SanLand concrete pulverizers can be used for both primary and secondary crushing operations. Abrasion resistant, high strength, alloy steel teeth provide decreased wear and increased durability
Amut develops thermoforming machines for hard food packaging
Thermoforming has gradually become a widely accepted technology, and the continuous improvement of processing equipment and materials has provided more new uses for thermoforming.
