Frequently Asked Questions (FAQ)

Yes, products with similar viscosity and chemical behavior can share a single filling machine. When switching between different oil formulations, we recommend flushing the dosing pump thoroughly and utilizing quick-release sanitary hose assemblies to eliminate cross-contamination between product runs.

Absolutely. All fluid-contact parts across our food and beverage filling lines are constructed using food-grade Stainless Steel 304 or acid-resistant Stainless Steel 316L, equipped with mirror-polished inner surfaces and quick-dismantle sanitary tri-clamp fittings that comply with GMP and CE regulations.

For high-viscosity foods or sauces containing solid particulates (such as Bolognese, mayonnaise, mustard, pesto, or jams), EAC Machinery Co., Ltd. recommends heavy-duty servo piston fillers or rotary lobe pump machines featuring jacketed heating hoppers, mechanical agitators, and non-drip pneumatic rotary valves.

A turnkey tube filling system includes:

• Automatic tube loading hopper & orientation system
• Volumetric/servo paste filling station
• Hot air / ultrasonic / mechanical fold sealing mechanism (for plastic or aluminum tubes)
• Batch code embossing & tail trimming station
• Integrated automatic cartoning and end-of-line case packing machinery

EAC Machinery Co., Ltd. tube filling and sealing machines deliver high precision accuracy within ≤ ±1%. Output capacity is fully adjustable from 40 to 120 tubes per minute depending on tube diameter, cream viscosity, and automation configuration.

Our automated tube filling units are equipped with Mitsubishi PLC touch-screen interfaces, servo motor drives, photoelectric tube alignment sensors, "No Tube - No Fill" protection, automatic temperature-controlled air heaters, and integrated seal strength testing modules.

Selection depends directly on your target production volume, labor budget, and expansion roadmap:

• Semi-Automatic Machines: Ideal for start-up operations, small-batch cosmetics, or pilot plants seeking low initial investment and reliable fill accuracy.
• Fully Automatic Filling Lines: Crucial for growing and enterprise manufacturers needing high speeds, minimal manual labor, and seamless integration with capping, labeling, cartoning, and palletizing machinery.

Liquid-Level (Overflow) Fillers fill containers to a precise visual height across all bottles, making them ideal for transparent glass or PET bottles where uniform shelf appearance is required. Volumetric Fillers (Piston, Flow-Meter, or Peristaltic Pump) inject an exact target fluid volume into each container regardless of minor glass thickness variations.

Yes. Our engineering department specializes in designing custom bottle pucks, star wheels, diving nozzle brackets, and clamping mechanisms to handle irregular, delicate, or unique container geometry seamlessly.
