Manufactured by Zhejiang Haoyuan Machinery Co., Ltd., the HY-330 Dual-Feed Warm Patch Packaging Machine is engineered for continuous production of self-heating warm patches and powder-based heat packs. The unit integrates powder filling, film sealing, and contour cutting into a single automated workflow, designed for industrial applications producing body warmers, medical heat patches, and herbal heating pads. Product contact surfaces are constructed from 304 stainless steel, meeting FDA 21 CFR Part 177.1520 and EU Regulation 10/2011 requirements for consumable product processing. The machine supports both standard rectangular and custom irregular patch shapes through color mark tracking technology, with changeover between product formats completed in approximately 45 minutes with standard tooling.

The machine supports two independent feeder configurations to accommodate different powder characteristics, including iron powder, activated carbon, vermiculite, and medicinal herb powders. Feeder types can be selected based on particle size distribution (50-200 mesh) and flow properties, with filling accuracy maintained at ±2% of target weight across production runs.
The photoelectric tracking system identifies registration marks on packaging film with 0.5mm precision, enabling production of custom contour shapes including neck patches, shoulder patches, and joint-specific warm packs. The system automatically adjusts film feed to maintain alignment, reducing material waste to less than 3% during steady production.
The sealing system applies 150-180°C temperature across 12mm wide seal bands, with dwell time adjustable from 0.8-1.5 seconds. This configuration achieves peel strength of 12-18N/15mm, preventing powder leakage during storage and transportation. Seal bars are coated with PTFE to reduce film adhesion and simplify cleaning.
The unit utilizes a Panasonic PLC with 7-inch MCGS touchscreen interface, supporting parameter storage for up to 50 product recipes. The system includes self-diagnostic functionality that displays fault codes for issues including low air pressure, film breakage, and temperature deviations, with error logs stored for maintenance reference. The interface supports 7 languages: English, Spanish, French, Korean, Russian, Japanese, and Arabic.
The machine is configured for production of disposable body warmers, 8-hour and 12-hour heat patches, and air-activated hand warmers. It processes standard iron powder formulations as well as patches containing ginger, mugwort, and other herbal additives for therapeutic applications.
For medical heat therapy patches, the stainless steel construction supports washdown procedures with pH-neutral cleaning agents. The metering system maintains consistent powder fill weights to ensure uniform heat output across production batches, meeting requirements for medical device packaging in most markets.

The machine requires a level concrete floor with minimum load capacity of 500kg/m², connected to 380V three-phase power and filtered compressed air supply. Cooling water connections require ½ inch NPT fittings with water pressure maintained at 0.2-0.3MPa. Haoyuan Machinery provides on-site installation and commissioning services, including 2 days of operator training for production staff.
Daily tasks include cleaning seal bars and checking air line filters. Weekly maintenance involves lubricating cam mechanism bearings and inspecting cutting blade sharpness. Monthly inspection of electrical connections and pneumatic seals is recommended, with annual gearbox oil changes required to maintain warranty coverage.
With properly calibrated feeders and consistent powder moisture content below 1%, the system maintains filling accuracy of ±2% of target weight. Accuracy may vary with extremely fine powders below 300 mesh or materials with high oil content.
Yes. The dual-feeder design allows two separate powder streams to be deposited into each patch, supporting formulations that require separated active ingredients. Feeder speed and vibration settings can be adjusted independently for each material.
The machine includes a 12-month warranty from the date of commissioning, covering manufacturing defects in materials and workmanship. Extended warranty coverage for 24 months is available at time of purchase, and spare parts availability is guaranteed for 10 years from delivery.
Each unit ships with CE marking documentation, electrical compliance certificates for Schneider components, and material certificates for 304 stainless steel product contact parts. Food contact material test reports are available upon request for commercial procurement applications.
