Filling Machines
1. For High-Viscosity Liquids like Sauces, Chili Sauces, and Butter
For high-viscosity products such as sauces, chili sauces, and butter, we recommend our piston-type filling machines. These machines draw product from the material tank and deliver precise fills into containers via the reciprocating motion of a piston, achieving a filling accuracy of up to ±1% to meet various packaging specifications.
To ensure the smooth flow of viscous materials, the machine is equipped with a heating and insulation jacket. This maintains the product within an optimal temperature range, temporarily reducing viscosity for easier handling. Furthermore, the specially designed filling nozzle prevents product adhesion and dripping, maintaining a clean production environment.
2. For Low-Viscosity Liquids like Soy Sauce and Vinegar
For low-viscosity liquids such as soy sauce and vinegar, the gravity-type filling machine is the optimal solution. Utilizing the natural force of gravity, it performs quantitative filling by controlling the opening and closing of fill valves. This design offers a simple structure, high filling speeds, and exceptional accuracy of up to ±0.5%.
To minimize foam generation, the machine employs a submerged filling nozzle. This allows liquid to flow gently into the container, reducing turbulence and impact. An integrated liquid level control system ensures consistent fill heights across every bottle.
3. For Particulate or Semi-fluid Liquids like Ketchup and Honey
For products containing particles or with a semi-fluid consistency, such as ketchup and honey, the screw-type filling machine is ideal. It advances product through the rotation of a screw to achieve measured filling. This method effectively handles liquids with solid particulates, ensuring even particle distribution without clogging.
The screw rotation speed can be precisely adjusted based on product viscosity and desired fill volume, with accuracy maintained within ±1%. The machine's internal pipeline is designed for smooth flow, minimizing product residue and simplifying the cleaning and maintenance process.

Capping Machines
1. Screw Capping Machine
The screw capping machine is primarily designed for sealing products like sauce bottles and honey jars. It utilizes advanced torque control technology to apply the precise amount of force when tightening caps. This ensures a perfect seal to prevent leaks while still allowing for easy opening by the end consumer.
Its capping speed is adjustable to match production line requirements. An integrated photoelectric sensor monitors the position and status of each cap. Any container with a missing or improperly tightened cap is automatically rejected, guaranteeing consistent product quality.
2. Press-On Capping Machine
The press-on capping machine is suited for products requiring a pressed seal, such as premium soy sauce and vinegar bottles. It firmly secures caps onto bottle necks by applying precisely controlled pressure. This machine is compatible with caps of various materials and shapes, including metal and plastic lids.
It operates at high speed for optimal efficiency and is equipped with an automatic cap feeding system. This enhances the level of production automation and minimizes the need for manual intervention.

Labeling Machines
We specialize in four core types of labeling systems: pressure-sensitive labelers, sleeve label applicators, hot-melt OPP labelers, and cold-glue paper labelers. While we supply the machinery only (labels must be sourced separately), we offer optional support to assist with label procurement.
The optimal machine is selected based on your container's shape, size, and specific labeling requirements—such as single-side application (for round or flat bottles), dual-side, triple-side, front/back, or multi-label configurations.
Our labeling systems are designed for seamless integration. They easily connect with coders for date/batch printing and are synchronized via conveyor belt with upstream or downstream equipment like fillers or shrink wrappers. We provide tailored recommendations based on your production speed, container design, and label specifications.
Please note: Label artwork and printing must be supplied by your designated printing partner.

Palletizer Units, Stacking Pallet Feeders, and Pallet Stretch-Film Wrappers
Palletizer:
This equipment is designed to pick up film-wrapped bottle packages and systematically stack them onto pallets. Pallets are automatically supplied by a pallet feeder. Once a load is successfully stacked, it is transferred via rollers to the turntable of the pallet stretch-wrapper. A photoelectric sensor detects the pallet's arrival, triggering the turntable to rotate and wrap the load with stretch film. This process ensures stability during transportation, minimizes the risk of tipping, and facilitates easy forklift handling for delivery to distributors or retail outlets.
Palletizers are available in various configurations. Some utilize pneumatic suction for gripping, while others employ robotic arms. Structurally, models include column-style and gantry-style designs. The column-style is suitable for small to medium-scale production lines, whereas the gantry-style, with its superior stability and load-bearing capacity, is ideal for large-scale, high-volume operations.
Pallet Feeder:
The pallet feeder automates the distribution of pallets, which serve as the foundational support for stacked loads. If a customer's process requires separator boards between layers, an additional dedicated machine is necessary. While placing bottom pallets and separators can be done manually, integrating this automated equipment significantly enhances line efficiency and reduces labor costs.
Pallet Stretch-Wrapping Machine:
Pallet stretch-wrapping machines are primarily categorized into two types: rotating turntable wrappers and non-rotating swing-arm wrappers. A rotating turntable machine, where the pallet load spins on a platform, is an excellent choice for stable, standard-sized loads. However, for extremely tall loads where rotation might compromise stability, or for pallets with irregular shapes, a non-rotating swing-arm wrapper is the preferred option. This machine wraps the film around the stationary load by rotating the film carriage on a vertical arm, making it suitable for secure wrapping of high or unstable palletized goods.
