Punch-and-die Thermoforming Technology
OMV Machinery has 60 years of experience in punch-and-die (“match metal”) forming technology. Parts are formed by a male and female mould and trimmed in place. This technology is widely recognized as the most adapt for high quality parts in case of high-shrinking resins. It applies, for instance, to polypropylene-based coffee capsules, portion cups, lids. OMV does not only build the former but also designs and manufactures the whole mould.
Inline Rim Rolling Technology
This technology is unique to OMV thermoformers, thanks to its way of extracting parts from the mould. Parts are delivered to a coining press right after the forming stage, which achieves good lip “rolling” with 100% efficiency. No loss of cups, no stops, no need of separate equipment after the former to rim roll and then re-separate the rolled stacks. Rim Rolling OMV Rim “Rolling” can be applied also to non-round objects such as square / rectangular portion cups and trays.
Inline Extrusion + Thermoforming Technology
OMV is a specialist in turnkey in-line thermoforming solutions for Polypropylene and PP Multilayer parts, which it pioneered in the industry. Having the sheet extruded and directly fed to the former allows for the highest process control to achieve the best wall distribution, rim flatness, and precision in critical points of the parts. At the same time, inline systems eliminate the need to stock sheet, handle scrap “sheet skeletons” and provide substantial energy savings.
OMV offers a full-fledged Tech Center to try new designs and/or new resins. With a small investment, parts can be thermoformed and tested in OMVs Tech Center before committing CapEx to buy the whole equipment. The complete service includes design-to-thermoforming and manufacturing of a test cavity, installation and test-runs on a dedicated pilot line as well as small modifications (e.g. to inserts) to zero-in the design to target.
