RPC-60-2 Automatic Nut Cup Filling & Sealing Machine

Product overview

The RPC-60-2 Automatic Cup/Tub Filling and Sealing Machine is engineered for high-speed, automated packaging of preformed cups and tubs containing nuts and other compatible free-flowing dry products. It integrates container feeding, indexing, servo-controlled product filling, sealing and finished-pack discharge into a continuous packaging process. With a rated output of 80–90 fills per minute, the RPC-60-2 provides a high-throughput solution for manufacturers seeking improved packaging efficiency, consistent operation and reduced manual intervention.

The machine adopts a full mechanical drive system designed to deliver stable performance during high-speed operation. Its open drive and machine layout provide better visibility of the working mechanisms while making routine inspection, maintenance and cleaning more convenient. A safety enclosure equipped with a safety relay and bleed valve further supports safe operation in demanding production environments. The open structure also reduces hard-to-clean dead corners, helping operators maintain better hygiene around the packaging area.

For efficient container handling, the RPC-60-2 is equipped with a large cup storage system that reduces the frequency of manual cup replenishment. The mechanical cup dropping mechanism provides stable and consistent container feeding without requiring speed-related parameter adjustments. The complete cup-dropping assembly can also be replaced as a set, helping simplify maintenance and format changes. Mechanical cup discharge provides more stable container removal compared with cylinder-based cup exit mechanisms.

The servo-controlled filling system is designed to improve filling consistency and help prevent product overflow during high-speed operation. The filling outlet can be removed without tools, making cleaning and routine maintenance easier. The quick-change mould design requires few or no tools, while the sealing head is also designed for convenient changeover. A self-balancing mould supports consistent sealing pressure and helps achieve reliable sealing results across production cycles.

For operators, the RPC-60-2 provides practical functions including jog mode for checking machine conditions during setup and troubleshooting, as well as one-button start for simplified daily operation. Combining high-speed mechanical performance, servo filling, easy changeover, accessible cleaning and reliable component configuration, the RPC-60-2 is a suitable solution for automated cup and tub packaging applications where productivity and operational stability are essential.
