RM100 Automatic Ropp Capping Machine Cap Screwing Machine Wine and Olive Oil Ropp Capping Machine

The RM100 Automatic ROPP Capping Machine is a factory-direct, roll-on pilfer proof (ROPP) capping solution engineered for liquor, spirits, wine, edible oil, pharmaceutical syrup, and chemical packaging lines. Manufactured by Shanghai YIMU Technology Co., Ltd., this automatic ROPP capper applies plain aluminum caps to bottles and forms threads during the sealing process while simultaneously creating an integrated tamper-evident band around the bottle neck.

Critical distinction: The RM100 is a mechanical roll-on capping machine, NOT an induction sealing machine. It uses precision thread rollers and pilfer rollers to physically deform an unthreaded aluminum cap onto the bottle neck finish — forming threads and the pilfer-proof band in a single continuous operation. This is fundamentally different from induction sealing, which uses electromagnetic energy to heat a foil liner. The ROPP process produces a tamper-evident aluminum closure that is permanently deformed to the bottle — providing both a visible security seal and a premium product presentation.

Why ROPP capping matters: In regulated industries such as spirits, pharmaceuticals, and export food products, tamper evidence is not optional — it is a compliance requirement. The ROPP closure creates a built-in pilfer-proof band that breaks visibly upon first opening, providing consumers and regulators with immediate visual confirmation that the product has not been compromised. The RM100 delivers this capability at industrial speed with factory-direct pricing.

The RM100's defining engineering capability is its simultaneous thread formation and pilfer band sealing. Unlike screw capping machines that apply pre-threaded caps onto pre-threaded bottles, the RM100 receives a plain, unthreaded aluminum cap and performs the entire closure formation in a single continuous operation.

The process works through precision mechanical rollers:

• Thread rollers press against the aluminum cap body, forming threads that conform to the bottle neck finish. The rollers apply a controlled sideload to deform the aluminum shell, creating closure threads that match the bottle's molded neck threads.

• Pilfer rollers simultaneously press the bottom edge of the cap into the bottle's annular ring, forming the tamper-evident pilfer band. This band remains attached to the cap upon first opening, breaking visibly to indicate tampering.

The result is a hermetically sealed, tamper-evident closure that provides both product security and premium shelf presentation. For liquor, spirits, wine, and export pharmaceutical products, this is not a luxury — it is a market requirement.

The RM100 is sold factory-direct from YIMU's Shanghai manufacturing facility — cutting out trading companies, importers, and regional distributors that typically add 30–50% to the final price. This vertical integration means:

• Lower equipment cost compared to equivalent machines from trading intermediaries

• Faster communication on customization, spare parts, and technical support

• Direct engineering access for line integration and capping parameter optimization

For manufacturers evaluating total cost of ownership, factory-direct purchasing eliminates a significant layer of overhead without compromising on quality or after-sales support.

The RM100 handles cap diameters from φ20mm to φ40mm and bottle diameters from φ35mm to φ120mm with heights from 50mm to 320mm. This range covers the most common bottle formats used in liquor, spirits, wine, olive oil, pharmaceutical syrup, and chemical packaging:

• Liquor & Spirits: Standard 750ml, 500ml, 375ml, and 200ml glass bottles

• Wine: Standard 750ml wine bottles with ROPP neck finish

• Edible Oil: 500ml, 1L, and 2L glass or plastic bottles

• Pharmaceutical Syrups: 60ml, 100ml, 200ml amber glass bottles

• Chemicals: Small to medium reagent and solvent bottles

The machine's adjustable capping head height allows quick changeover between bottle heights without mechanical tooling changes. The capping head itself uses a four-wheel balanced lever head that crimps the cap edge automatically — easy to adjust and ensuring smooth, crease-proof capping quality.

The RM100 produces tight, leak-proof closures with no gaps, no scratches, and tight cap bottom sealing. The bottle mouth positioning device increases the positioning accuracy of the bottle mouth and the capping head, which improves cap utilization and reduces cap damage rates.

The machine body is constructed from SUS 304 stainless steel — the industry standard for food, beverage, and pharmaceutical equipment. This corrosion-resistant material withstands humid production environments, wash-down procedures, and the hygiene requirements of GMP-regulated facilities.

The RM100 uses a PLC control system with an intuitive touch screen interface. Operators select a preset recipe for each bottle format — bottle height, cap diameter, roller pressure — and the machine automatically adjusts capping parameters. Changeover between product SKUs takes minutes, not hours. No mechanical re-calibration required.

Every RM100 comes with a machinery test report and video outgoing inspection. The machine carries a 2-year warranty with free spare parts within the warranty period and lifetime online and video technical support.

The ROPP capping process transforms a plain aluminum cap into a threaded, tamper-evident closure through a precise multi-stage mechanical operation. Here is how the RM100 executes each stage:

Stage 1 — Cap Placement. A plain, unthreaded aluminum ROPP cap is placed onto the bottle neck. The cap sits loosely on the bottle — the threads have not yet been formed. Cap placement is critical: the cap must be centered on the bottle neck to ensure uniform thread formation.

Stage 2 — Top Load Application. A pressure block descends onto the cap top, applying a controlled downward force (topload). This topload presses the cap's internal liner against the bottle's mouth curl, creating the primary seal. The topload also stabilizes the cap during the subsequent roller operations.

Stage 3 — Thread Roller Formation. Thread rollers press against the exterior of the aluminum cap body with a controlled sideload. As the bottle and cap rotate, the rollers deform the aluminum shell inward, forming threads that precisely match the bottle neck's thread profile. The rollers typically make three or more passes to form a smooth, complete thread.

Stage 4 — Pilfer Band Formation. Simultaneously with thread formation, pilfer rollers press the bottom edge of the cap into the bottle's annular ring — the small ridge below the threads. This creates an inwardly oriented protrusion that locks the pilfer band to the bottle. The pilfer band remains attached to the cap upon opening, breaking visibly to indicate tampering.

Stage 5 — Roller Retraction & Release. After thread and pilfer band formation, the thread rollers and pilfer rollers retract. The pressure block releases its topload. The sealed bottle advances to the next station, and the next bottle enters the capping station.

Problem 1: "Our current capping machine can't handle plain aluminum caps." Standard screw capping machines apply pre-threaded caps. ROPP caps arrive as plain aluminum shells that require thread formation during capping. The RM100 is purpose-built for this application — a standard screw capper cannot substitute for a dedicated ROPP capping machine.

Problem 2: "Cap damage rates are too high, increasing packaging costs." The RM100's bottle mouth positioning device increases the accuracy of the bottle mouth and capping head alignment, improving cap utilization and reducing the cap damage rate. The four-wheel balanced lever head crimps the cap edge automatically without scratching or crushing.

Problem 3: "Changeover between bottle formats takes too long." Mechanically adjusted cappers require manual recalibration when switching between bottle heights or cap diameters. The RM100 stores recipe parameters in the PLC memory — changeover is as simple as selecting the new SKU on the touch screen. No mechanical adjustments. No production delay.

Problem 4: "We need a premium closure appearance for our brand." ROPP aluminum caps provide a premium, metallic finish that plastic screw caps cannot match. The RM100 produces smooth, crease-proof capping with a clean thread profile — enhancing the shelf appearance of your product.
