Thermoforming has gradually become a widely accepted technology, and the continuous improvement of processing equipment and materials has provided more new uses for thermoforming.
Forming and cutting integration
Italian company Amut recently developed a thermoforming machine for rigid food packaging. This production system (membrane co-extrusion and compound thermoforming) is designed for the production of polypropylene (PP) cups (single-layer transparent or triple-layer opaque, with inner cores of recycled materials) with a production capacity of approximately 60,000/ Hours (calculated at 200 cubic centimeters/cup capacity).
Viewed from outside, the equipment is a set of independent working systems, which mainly include: raw material feeding and weighing and feeding systems.
Extrusion section includes: AMUT single-screw extruder, EA100 series, equipped with 35:1 length/diameter ratio plasticizing system, oil-operated two-way screen changer, gear pump and static mixer, AMUT single screw Extruder, EA48 series, equipped with a 33:1 length/diameter ratio plasticizing system with screen changer; three-layer co-extruded flow box with interchangeable feeders; horizontal flat die with internal melting Body adjustment rod, the maximum effective width is 900 mm.
Thermoforming section includes: In-mold synchronous molding and cutting device, using the template tilt technology, easy to quickly stack the final product in multi-cavity production; effective molding / cutting area of ​​780 × 740 mm. When PP is used, it reaches 22 to 23 cycles per minute, and 27 to 28 times when using PS; the tilting process of the lever system is controlled by a cam fixed to four rigid columns.
The device can also be equipped with AMUT's new edge forming machine, designed specifically for PP products, equipped with thermostat screws and automatic packaging machines.
Production of food packaging MEICO of Italy introduced FC780E and FC600E new thermoforming machines. The machine is manufactured by its Swiss sister company WMWrapé„„ping Machine. This molding/cutting/stacking/(vacuum and pressure) thermoforming machine is all driven by a motor (servo motor).
Both models (including standard models) contain a variety of features that can process all types of rolled thermoformed sheets up to 2 mm in thickness, including HIPS, GPPS, PET, PVC, PP, OPS, and EPS.
Each of the two independent heating boxes on the upper and lower sides is equipped with a proportional heating zone. Both the molding section and the cutting section are equipped with upper and lower independent dynamic pressure plates. The stacking device can also be equipped with devices for counting, ejecting and curling of edge materials.
The advantages of the FC780E and FC600E models also include: Fast mechanical circulation, speeds of up to 40 beats per minute when using 350 micron sheets for A-PET pallets; low noise; low energy consumption; quick set-up due to the use of special Mechanical design and special program for single board machine, easy to replace the mold.
Single-station and multi-station Italian QSGroup's plastics department designs and manufactures various thermoforming machines, providing single-station to multi-station online models. Its multi-station model is designed specifically for the refrigeration industry and is used to thermoform innerliners and inner doors to increase production speeds. To meet customer needs, the company designed two sheet transfer systems: a chain transfer thermoforming line and a mold transfer thermoforming line.
For single-station models, the company produces a wide range of thermoforming machines for use in a variety of industries including hygiene, automotive, electrical appliances, and packaging. The equipment can be equipped with different heating systems, from conventional ceramic heating tubes to quartz heating tubes or halogen heating tubes, to suit the processing needs of different products. Can also configure a variety of auxiliary equipment, including automatic sheet loading equipment and automatic thermoforming parts unloading equipment, etc., with more perfect features. \
In addition to plastic sheet thermoforming single-station models, the company's plastics department also designs and manufactures roller feeding thermoforming machines and single-station models specifically for the automotive industry for lamination of interior components.
Leisure chairs are a type of furniture used for rest, relaxation, and enjoyment, typically with comfortable seat and backrest designs to provide optimal comfort and support.
