Description
Manual ROPP Capping Machine
Precision Aluminum Cap Sealing for Small-Scale Bottling – No Electricity Required
Product Overview
The Manual ROPP (Roll-On Pilfer Proof) Capping Machine from Sonic Industries is a hand-operated solution designed for sealing aluminum ROPP caps onto glass or plastic bottles. It is the go-to solution for small-scale production, startups, laboratories, and field operations that require a cost-effective, electricity-free, and portable capping tool.
This compact yet powerful machine ensures a tamper-evident, leak-proof seal using thread-rolling knurling dies. The machine forms threads directly onto the aluminum cap, pressing it securely against the bottle neck without damaging the bottle or the product.
Whether you’re sealing pharmaceutical syrups, ayurvedic liquids, wine bottles, or essential oils, the Manual ROPP Capping Machine delivers professional-grade sealing with every turn.

How It Works
The Manual ROPP Capping Machine works by manually rotating a set of hardened rollers around an aluminum cap placed on a filled bottle. These rollers form threads and knurling into the cap by pressing it against the bottle neck.
Step-by-Step Operation:
-
Place the filled bottle on the base plate.
-
Insert a ROPP cap loosely on top of the bottle.
-
Adjust the height of the roller head to align with the cap.
-
Rotate the handle in a circular motion.
-
The knurling rollers crimp, thread, and seal the cap tightly.
-
Remove the sealed bottle and repeat.
This process delivers a tamper-proof, pilfer-evident seal using mechanical pressure—no electricity or compressor needed.
