RPC-60 Automatic Tub Filling, Sealing & Lid Placing Machine

Product overview

The RPC-60 Automatic Preformed Tub Filling, Sealing and Lid Placement Machine is an integrated packaging solution designed to automate tub feeding, product filling, sealing, lid placement and finished-pack discharge. With a rated output of 40–55 fills per minute and a maximum speed of 55 cups per minute, this automatic tub filling machine provides stable, repeatable performance for manufacturers seeking efficient and labor-saving packaging.

Built with a full mechanical drive system, the RPC-60 supports reliable high-speed operation with reduced dependence on complex parameter adjustments. Its open machine structure provides convenient access to mechanical and electrical components, simplifying inspection, maintenance and troubleshooting. A safety enclosure with a safety relay and bleed valve further supports safe operation.

The dedicated tub storage system reduces manual replenishment frequency, while the mechanical cup dropping mechanism consistently separates and positions tubs into the indexing mould. The mechanical cup ejection system also helps achieve stable discharge performance. As a practical cup filling and sealing machine, the RPC-60 is designed for smooth and continuous packaging operations.

For efficient format changes, the quick-change mould requires few or no tools, helping minimize downtime. The discharge nozzle can also be removed without tools for easier cleaning and maintenance. The open layout reduces hard-to-clean areas and improves accessibility around the working zone.

The RPC-60 combines automatic filling, sealing and lid handling in one system. As a versatile tub sealing machine and lid placing machine, it can be configured according to product characteristics, filling volume, tub dimensions, sealing material, lid format and feeding requirements, making it suitable for a wide range of preformed-tub packaging applications.

Typical applications

Suitable for automatic filling, sealing and lid placement of preformed tubs with products compatible with the selected feeding and filling system. Final suitability depends on the product, fill quantity, tub dimensions and closure format.

Process flow

• Load empty tubs into the cup storage system.
• Mechanically separate and place each tub into the indexing mould.
• Feed and fill the required product into the tub.
• Apply the specified sealing material at the sealing station.
• Place the outer lid on the sealed tub.
• Mechanically eject and discharge the finished pack.
