At this year’s CHINAPLAS, Illig will exhibit its RDM-K and RDK series automatic roll-fed thermoforming machines. The current 3rd generation RDM-K models are designed for the high-volume production of cups in diverse shapes and sizes from thermoplastic material stock. RDK series machines likewise rely on roll-fed material but produce bowls, trays and hinged packs of the type employed, e.g., to preserve food in transport and on supermarket display shelves.
An RDM 70K with a 680 x 300 sqmm forming surface will be shown making APET cups at a rate of close to 45,000 per hour using a 18 cavity mold. According to Illig, the use of servomotors for all machine motions raises the speed of each function, subject to a velocity profile adapted to the given process stage. The new RDM-K thermoformer reduces the demand of forming air by 50%, resulting in a vastly more dynamic forming air build-up.
APET will also be the material processed by an RDK 80 IC with forming surface of 756 x 565 sqmm to make trays in a 10-cavity mold at 50 cycles per minute. The “IC” suffix denotes machines featuring the new “ILLIG Intelligent Control Concept”. This system comprises mutually compatible control modules for a dynamic optimization of all processes, making the machine easier to operate, accelerating startup of new molds, eliminating ambient influences through appropriate process control, and boosting process stability and process quality.
