HIPOWER HC‑2615Y‑4AC Auto‑Rotary Ultrasonic Cylinder Bottom‑Welding Machine: Automated Production Solution For Clear Plastic Tube Bottom Sealing

Clear plastic cylinders made of PVC, PP, APET and PET‑G are widely used for candy, gift, toy, stationery and fishing‑gear packaging. Traditional bottom‑sealing processes face multiple bottlenecks. Single‑station machines suffer low throughput since loading/unloading occupies welding cycle. Conventional ultrasonic machines require manual frequency tuning and demand skilled operators. Without fault‑monitoring protection, overload or horn damage may harm internal components. Coarse amplitude adjustment makes it hard to match thin or thick sheets. Standard fixed‑station‑count machines cannot handle flexible multi‑SKU production.

To solve these industry pain points, DONGGUAN HIPOWER LTD launches HC‑2615Y‑4AC auto‑rotary ultrasonic cylinder bottom‑welding machine. It comes with standard 4‑station rotary table, upgradeable to 6‑station or 8‑station on request. It features power‑on auto‑frequency‑tuning, intelligent fault alarm system and 1‑step fine amplitude adjustment, operated via PLC+HMI touch‑screen. Designed for ultrasonic bottom sealing of transparent plastic cylinders, it supports mass‑volume production and fast product change‑over, with comprehensive non‑standard customization available.

Core Technical Features of HC‑2615Y‑4AC

1. 2600W Ultrasonic Output, Auto‑Tuning Without Manual Adjustment

Equipped with 2600W /15KHZ ultrasonic generator. Auto‑frequency‑tuning locks optimal working frequency after power‑on. Operators are freed from manual tuning. System monitors real‑time frequency deviation and triggers early warning. It delivers scratch‑free and firm sealing for thin PP sheets as well as thick APET / PET‑G eco‑friendly cylinders.

2. Customizable Multi‑Station Rotary Table, Parallel Operation Boost Throughput

Standard 4‑station rotary indexing table, customizable to 6‑station or 8‑station. Multiple working steps including feeding, ultrasonic welding and finished‑part picking run in parallel. Operators only place cylinder bodies and bottom lids manually. Welding procedure runs automatically. Ideal for high‑volume production of candy tubes, fishing‑gear containers and gift cylinders.

3. Stepless Amplitude Adjustment with 1‑Percent‑Step Fine Tuning

Ultrasonic amplitude ranges from 0‑100% with fine 1% incremental adjustment. It precisely matches energy output for sheet thickness from 0.17 mm to 0.5 mm. Thin sheets avoid piercing or cracking while thick materials achieve sufficient bonding strength for varied cylinder bottom‑sealing requirements.

4. Multi‑Layer Intelligent Protection Ensures Stable Operation

Built‑in comprehensive intelligent protection monitors power overload, over‑temperature, frequency drift, horn abrasion and over‑current condition. Audible‑visual alarm activates once abnormality occurs, protecting ultrasonic generator and welding horn, enabling long‑hour non‑stop factory‑floor operation.

5. Import Anti‑Interference Digital Chip & Intuitive PLC Touch‑Screen

Imported high‑performance anti‑interference digital chip ensures stable performance under factory‑site voltage fluctuation and multi‑device interference. PLC+HMI touch‑screen allows welding‑time setting from 0.01‑9.99 seconds. Multiple process recipes can be saved and recalled for fast product switch for tubes of different diameters and heights. Slider‑track mechanism simplifies horn‑gap manual adjustment and routine maintenance.

6. Full Customization & Complete ODM/OEM Support

Station quantity, horn travel, machinable cylinder diameter & height can all be tailor‑modified. Optional auto‑loading / auto‑unloading manipulators and product inspection modules are available. Private‑label ODM / OEM service is supported. The machine can connect with cylinder‑forming and curling machines to build fully‑automatic cylinder‑packaging production‑lines.

Frequently Asked Questions

Can HC‑2615Y‑4AC seal food‑grade PET‑G cylinder bottoms?

Yes. Ultrasonic non‑thermal‑conduction bonding plus fine amplitude tuning delivers strong scratch‑free sealing, complying with food‑safe requirements for candy packaging tubes.

Can I upgrade from 4‑station to 6‑station or 8‑station?

Customization is available. Standard configuration is 4‑station; 6‑station or 8‑station rotary tables can be ordered for higher‑capacity demand.

Does changing cylinder diameter require lengthy re‑tuning?

Swap corresponding mould, recall pre‑saved recipes on touch‑screen. No repeated amplitude or welding‑time adjustment required for fast change‑over.

Will the machine give alarms for horn wear or overload faults?

Complete intelligent protection system triggers alarms for overload, over‑heat, frequency deviation and horn wear to remind operators for maintenance and safeguard ultrasonic core components.

What about warranty for customized machines?

1‑year full‑machine warranty plus lifelong remote‑technical‑support. Engineers provide on‑site installation, commissioning and operator training. All technical inquiries get response within 24 hours.
