At CHINAPLAS 2017, ILLIG will debut the production of thermoformed liquid-tight containers with lid in Hall 5.1, Stand K21.
The containers are manufactured on an automatic pressure forming machine, type IC-RDK 80, with a 12-up container mold out of transparent PP. The Heilbronn company developed the 'take-away container' which can be tightly closed by a lid based on requirements by customers from the Asian market. In Asia hot soups and meals are filled in containers to go by restaurants and mobile snack booths. So far such a cost-effective and safe transport solution does not exist. ILLIG packaging specialists designed and realized all stages of the pack development: From the first idea and material selection through to mold production. This also included own application tests with respect to tightness and stackability (top load).
ILLIG thermoforming technology
With IC-RDK series ILLIG developed a forming and punching technology suitable to achieve excellent part quality and reproducibility of packs. The machines feature high availability and easy operation. Heated materials are formed by means of pre-stretcher and compressed air; the part is punched out of the material in the same cycle. Thanks to this method, parts can be manufactured without punching mismatch in the rim area and thus automatic pack processing is improved.
Complete production line for drinking cups on trade fair stand
A fully automated production line for drinking cups - everything from one source - will also be showcased at the trade fair. The forming machine is a state-of-the-art IC-RDM 70K automatic roll-fed machine. Drinking cups are manufactured on this line with an 18-up cup mold out of APET, forming area 680 mm x 300 mm. The trade fair machine is combined with an in-line SZA 73c stacking machine of modular design. The stacking machine can be variably equipped with different discharge options. Whenever the application changes the SZA 73c can be easily adapted thanks to the modular system.
Machines of the IC-RDM K series are also frequently used as in-line systems with pre-linked extruders, e.g. for large-volume production of drinking cups in quantities of millions. The ILLIG IC (ILLIG Intelligent Control Concept) supports the aspects relevant for large-volume production. It includes modules for general process optimization, high productivity and availability as well as minimization of operation costs.
Leading IML-T technology
Moreover, ILLIG will present the decorative and economic potentials of in-mold labeling in thermoforming (IML-T) at Chinaplas. IML-T lines are realized with so-called cup machines of the RDM-K series. This decoration technology is also integrated in form, fill and seal lines (FSL lines). An IML unit removes the printed blanks (labels) from a magazine and places them in the mold cavities in the forming station of the thermoformer. Every cavity can be equipped individually with a label, thus product changes can be performed fast and easily. The label bonds true to contour and permanently with the part wall during the subsequent forming process. Currently, ILLIG is the only supplier of an IML system in thermoforming (machine and mold technology) worldwide. Meanwhile, several machines have been put into operation on the market.
Cleantivity – Cleanliness in machine manufacturing and availability
Derived from the comprehensive expertise in the field of hygiene in form, fill and seal lines (FFS lines), ILLIG transferred the technology of cleanliness in the production process to its thermoformers – this is accompanied by higher machine availability. ILLIG calls this concept Cleantivity - derived from the terms cleanliness and productivity. It is our intent to extend operating time, running time and, ultimately, quality time of the thermoforming machines, in order to achieve a high line output of parts of excellent quality.
