The GD-380A Fully Automatic Premade Pouch Feeding & Packaging System is an integrated, high-efficiency solution engineered to pack weighable products—such as granules, tablets, and irregular-shaped items—into premade pouches with stable output and consistent quality. Centered on an 8-station rotary bag feeder and matched with the HX-A14 14-head waterproof multihead combination weigher, the system automates the full packaging cycle: pouch picking, opening, filling, air exhausting, sealing, and finished-bag discharge. Product-contact components are manufactured in 304 stainless steel to support hygienic production and corrosion resistance, while the PLC-based control architecture ensures repeatable timing, reliable interlocks, and smooth line coordination. Designed for demanding factory environments, the GD-380A line delivers clean seals, accurate dosing, and reduced labor dependency—ideal for manufacturers upgrading from semi-automatic operations to standardized, scalable pouch packaging.
Product Introduction
The GD-380A system combines bag handling, precision weighing, and controlled sealing into one coordinated packaging line. Premade pouches are loaded into the magazine, then automatically picked and positioned by the rotary feeder. After pouch opening confirmation, the weigher doses product according to the target weight, followed by controlled exhausting to improve pack appearance and reduce headspace. Pneumatic sealing and intelligent “no bag/no fill/no seal” protection help prevent spillage and contamination, improving both yield and cleanliness. With industrial-grade electrical and pneumatic components and a robust cam-driven station mechanism, the system is built for stable, continuous production.
Product Features
End-to-End Premade Pouch Automation
From pouch loading to finished-bag output, the workflow is fully automated: pick & place, open, fill, exhaust, seal, and discharge. This streamlined process reduces manual contact, stabilizes line rhythm, and improves overall packaging consistency for multi-shift production.
Stable 8-Station Rotary Platform with Cam Transmission
The rotary structure uses a mechanical cam transmission to maintain smooth indexing and repeatable station timing. This supports continuous operation with typical production rates of 10–30 bags/min, while common system configurations may reach 15–35 packs/min depending on product flowability, pouch format, and fill weight.
Accurate Multihead Weighing for Mixed Shapes
Paired with the HX-A14 14-head 1.6 L waterproof combination weigher, the system is optimized for products that are easy to weigh but may vary in size or shape. Standard packaging specifications typically cover 100–2000 g, with accuracy commonly within ±0.5% to ±1% depending on material characteristics and target weight.
Enhanced Sealing Quality with Intelligent Detection
Pneumatic sealing with dual sealing devices strengthens seal integrity and helps maintain stable sealing results across common premade pouch structures. Intelligent detection enables “bag present = fill and seal” logic, while “no bag = no fill/no seal” safeguards protect against waste, leakage, and heat-seal contamination. A sponge exhausting mechanism removes trapped air before sealing to improve pouch appearance and reduce bulging.
Industrial Controls for Efficient Operation and Diagnostics
A Siemens PLC and Siemens color touch screen provide centralized control, alarm prompts, and self-diagnosis for faster troubleshooting and smoother operation. Two-way temperature control for horizontal sealing improves sealing repeatability, while Schneider/OMRON electrical components and AIRTAC pneumatic elements enhance long-term reliability and serviceability.
Hygienic 304 Stainless-Steel Product Zone
All product-contact parts are constructed from 304 stainless steel for hygienic handling and corrosion resistance. Exposed surfaces are predominantly 304 stainless steel or aluminum alloy (excluding moving parts), supporting easier cleaning and a professional finish for food and health-related packaging environments.
