Single Head Automatic Screw Capping Machine for Bottles 16–75 mm Cap Diameter

Overview

The Single Head Automatic Screw Capping Machine from Yucheng Machinery is a precision-driven capping solution for production lines that require consistent torque-controlled cap application across a wide range of bottle and cap types. Handling cap diameters from 16 mm to 75 mm, it is compatible with screw caps, child-resistant caps, anti-theft caps, and flip-top closures on plastic (PE, PET, PP, HDPE) and glass bottles — covering virtually every screw-cap format used in food, cosmetic, pharmaceutical, and household chemical packaging.

Capping is one of the most torque-sensitive operations in a packaging line. Too little torque causes leaks in transit; too much cracks caps or strips threads. The Yucheng single head capper eliminates this variability through a magnetic clutch torque control system that applies precisely the torque you specify — consistently, cycle after cycle — without relying on operator judgment. Torque is adjustable from the PLC control panel, enabling quick adaptation when switching cap sizes or materials.

At 20–45 containers per minute, this machine suits small-to-medium production lines and is a direct upgrade from manual or handheld capping. Its inline design integrates with filling machines, conveyors, and downstream labeling equipment. Built by Dongguan Yucheng Machinery Technology Co., Ltd. (YCTAUTO), the machine features full stainless steel construction and an anti-slip bottle clamping mechanism that holds containers securely during cap tightening.

Key Features & Advantages

• Magnetic Clutch Torque Control — Delivers precise, adjustable capping torque that disengages automatically when the set torque threshold is reached. This prevents over-tightening, cap damage, and thread stripping — critical for child-proof, anti-theft, and plastic screw caps that have defined torque specifications.

• Wide Cap Diameter Compatibility: 16–75 mm — Covers the full range of common screw cap sizes from small pharmaceutical and cosmetic vials (16 mm) up to large-mouth containers and jerry-can closures (75 mm). Quick changeover between sizes takes minutes with minimal tooling.

• 20–45 pcs/min Capping Speed — Consistent capping throughput suitable for small and medium production lines, capable of matching most semi-automatic or moderate-speed filling machines.

• Compatible with Plastic & Glass Bottles — The anti-slip bottle clamping mechanism adjusts to hold both plastic and glass containers securely during capping without scratching or deforming the bottle body.

• PLC Control with Touchscreen HMI — All machine parameters — capping torque, conveyor speed, capping head height — are set and monitored on the color touchscreen. Saved recipes allow fast product changeover with one-touch recall.

• Anti-Slip Bottle Clamping Mechanism — Dual-belt or chuck-style clamping holds bottles firmly during the capping stroke, preventing rotation or misalignment that causes cross-threading or miss-cap events.

• Stainless Steel Construction — Full machine frame and liquid-contact components in stainless steel meet hygiene standards for food, pharmaceutical, and cosmetic environments and resist corrosion from cleaning chemicals.

• Inline Production Integration — Machine dimensions of 1950 × 740 × 1600 mm and standard conveyor height compatibility make it straightforward to insert into existing filling-labeling lines. Electrical integration signals for upstream/downstream equipment are included.

Technical Specifications

Applications

The single head screw capping machine is deployed across a broad range of industries:

• Food & Beverage — Bottled water, juice, edible oil, soy sauce, vinegar, honey, jam, ketchup, seasoning bottles, energy drinks

• Cosmetics & Personal Care — Shampoo, conditioner, body lotion, face cream jars, toner bottles, mouthwash, sunscreen

• Pharmaceutical & Health — Medicine bottles, supplement containers, vitamin capsule jars, syrup bottles, eye drop bottles

• Daily Chemicals & Household — Liquid detergent, fabric softener, floor cleaner, disinfectant, hand sanitizer

• Chemical & Industrial — Lubricant bottles, cleaning agent containers, agrochemical jugs (where material compatibility applies)

The machine handles both round and square bottle profiles, provided the bottle is conveyor-stable and the cap is a standard screw or lug-type closure within the 16–75 mm range.

Why Choose Yucheng Machinery

• Specialized Packaging Equipment Manufacturer — Dongguan Yucheng Machinery Technology Co., Ltd. (YCTAUTO) designs and manufactures filling, capping, sealing, and labeling equipment as its core business, with deep application knowledge across food, cosmetic, and chemical packaging lines.

• Magnetic Clutch Advantage — Many low-cost cappers use simple friction clutches or fixed-torque designs that drift over time. Yucheng's magnetic clutch system maintains consistent torque output throughout the production shift, protecting cap integrity and bottle thread condition.

• In-House Quality Control — Every capping machine is tested for torque consistency, clutch engagement accuracy, conveyor belt alignment, and HMI function before shipment. You receive a calibrated, production-ready machine.

• OEM & ODM Capability — We customize capping head geometry, conveyor dimensions, and control specifications to match your line layout. Private labeling is available for resellers.

• Complete Packaging Line Solutions — Yucheng supplies filling machines, foil sealers, labeling machines, and cap sorters alongside capping equipment, enabling turnkey packaging line supply from one source.

Frequently Asked Questions

Q: How do I adjust the capping torque for a new cap size?

A: Torque is adjusted via the magnetic clutch setting on the touchscreen control panel. We recommend a brief trial run on sample containers, then verify removal torque with a torque meter before starting full production.

Q: Can the machine handle plastic and glass bottles of the same cap size in the same run?

A: Yes. The capping head and torque settings are independent of bottle material. Switching between bottle materials of the same cap diameter requires only a clamping width adjustment.

Q: What cap formats does the machine NOT support?

A: The machine handles screw-type and flip-top closures. It is not designed for press-on snap caps, cork stoppers, crimp caps, or ROPP aluminum caps, which require dedicated equipment. Contact us for alternatives.

Q: How long does a cap size changeover take?

A: Changeover within the 16–75 mm range typically takes 10–20 minutes, including head adjustment, guide rail repositioning, and a short trial run. No specialized tools are required.

Q: What is the minimum order quantity (MOQ)?

A: The standard MOQ is 1 unit. Single-machine orders are welcome for line evaluation or small production operations. Volume pricing is available for bulk orders — contact our sales team for details.

Q: What warranty and after-sales support do you provide?

A: Yucheng provides a 12-month warranty on components. Every machine ships with an operation manual and setup video. Remote technical support is available during installation and through the warranty period, and spare parts are dispatched promptly.

Q: Can this capper be connected directly to a filling machine output?

A: Yes. The machine is designed for inline integration. Conveyor height and belt speed are configurable to match your filling machine output, and electrical signals for upstream/downstream synchronization are available.
