The Speedformer KMD 90 from Kiefel GmbH (U.S. office Kiefel Technologies, Portsmouth, N.H.) is a pressure forming machine that reportedly offers higher productivity due its ability to run at faster cycle times and form bigger surface areas.
The machine can run a range of sheet materials, including PS, OPS, PP, PE, PVC, PET, PLA or CPET. Black ceramic heaters in the heating station permit brittle material like PS and PLA and thick materials to be formed efficiently. Accurate and reproducable width adjust of the chain rails are said to ensure a precise cutting position.
Centric servomotor-actuated knee-lever drives, which reportedly provide high stability and smoothness, along with independent pre-stretching plugs on the upper and lower table, are said to ensure flexibility and a high product-quality.
A separate tool change stations offers a fast and ergonomic operation. This station is situated between forming and cutting station.The tool sets are changed in block, heavy tools that are supported by big ball bearings.
A down stacker places the finished products on a conveyor belt below the film level. The unloading height of 1 m is said to be ergonomically convenient.
A Siemens Simotion control system and a touch screen complete the picture of easy handling and operation.Two separate lubricating systems for index and motors and a punching delay timer, which reduces the angel hair effect, round off the package.
