As a professional Shanghai-based manufacturer, we design and supply a complete range of automatic metering packaging machines engineered for industrial-scale filling and packaging of powder, liquid, paste, and granular materials. Our equipment serves diverse sectors including chemical manufacturing, building materials, food processing, pharmaceuticals, and specialty industrial applications.

Every machine we produce is built around three foundational principles: market responsiveness, continuous innovation, and verified quality. Whether you require a standalone unit or a fully integrated packaging line, our engineering team delivers solutions configured precisely for your material type, output volume, and operational environment.

What Is an Automatic Metering Packaging Machine?

An automatic metering packaging machine is a precision industrial system that automatically measures, fills, and seals product into bags or containers at high speed without continuous manual intervention. These machines combine a metering or weighing system, a filling mechanism, a sealing method, and a conveying or discharge system into one automated workflow.

They are designed to reduce labor costs, improve packaging consistency, minimize material waste, and meet the throughput requirements of modern production lines. The specific configuration — particularly the valve port type and filling mechanism — depends on the physical properties of the material being packaged.

Product Range

Our catalog includes, but is not limited to:

1. Automatic Weighing Packaging Machine : High-precision gravimetric systems suitable for powders, granules, and bulk solids. Configured with load cell sensors and PLC control for real-time weight verification.
2. Anhydrous Citric Acid Packaging Machine : Specialized equipment designed for the hygroscopic properties and fine-particle characteristics of anhydrous citric acid, ensuring consistent fill weight and sealed packaging integrity.
3. Thickener Packaging Machine : Purpose-built for viscous and semi-viscous thickener materials that require controlled flow management during the filling process.
4. Single-Mouth Valve Packaging Machine : A widely used industrial solution for cement, mortar, mineral powder, and similar dry bulk materials. The valve mouth allows the bag to self-seal after filling, reducing contamination risk and improving line efficiency.
5. Mortar Packaging Machine : Optimized for dry mortar, masonry mortar, bonding mortar, and related cementitious products. Available in configurations from 200L gesso packaging to 1000L mortar packaging capacity.
6. Big Bag (FIBC / Bulk Bag) Packaging Machine : For large-format industrial bags used in bulk shipping of powders and granular materials. Suitable for ton-bag configurations across chemical, mining, and construction industries.

Related equipment in our line also includes an 18KG stainless steel packaging machine, a 5L thermal insulation material packaging machine, a 1200KG high-capacity packaging machine, and a 200L gesso packaging machine, among others.

 

Valve Port and Filling Mechanism Options

One of the most critical factors in selecting the correct packaging machine is matching the filling mechanism to the material’s physical characteristics — its flowability, particle size, density, and moisture sensitivity. We offer a full spectrum of configurable valve port and opening types:

• Pneumatic Valve Port : Uses compressed air actuation to open and close the fill spout with high speed and reliability. Suited for high-throughput production lines.
• Ultrasonic (Sealing) Valve Port : Employs ultrasonic energy to seal the valve bag opening after filling, ensuring airtight packaging for moisture-sensitive or fine-powder materials.
• Impeller Type / Air Flotation Type : Impeller filling uses a rotating multi-blade system to convey and fill material at high speed. Air flotation assists with low-bulk-density powders that require aeration for uniform flow.
• Spiral Valve (Auger-Type) : A horizontal or vertical screw feed delivers controlled, precise metering of powders and granular materials. Preferred where dosing accuracy is the primary requirement.
• Screw Opening : Mechanically actuated screw-driven opening system for stable, repeatable fill port control.
• Gravity Valve Port : Relies on the natural fall of material under gravity. Ideal for free-flowing granules or coarse powders where speed and simplicity are priorities.
• Gravity Opening : A gravity-assisted opening mechanism that reduces mechanical complexity while maintaining consistent bag placement and discharge.
• Belt Type Opening : Uses a belt-driven mechanism to open bag mouths precisely, often integrated with automated bag placement systems for semi-continuous operation.

Because different materials respond differently to each filling method, selecting the right configuration is not a one-size-fits-all decision. Our technical sales team works directly with clients to analyze material properties and recommend the optimal configuration — at no obligation.

Materials and Industries Served

Our automatic metering and weighing packaging machines handle a broad spectrum of materials across multiple physical states:

• Powder materials: cement, dry mortar, gypsum, citric acid, chemical powders, talc, calcium carbonate, mineral powders, metal powders, ultrafine powders
• Granular materials: fertilizers, resins, salt, sugar, grain, seeds
• Paste and viscous materials: thickeners, adhesives, sealants, specialty construction pastes
• Liquid materials: industrial liquids, chemical solutions

Industries regularly served include: building materials manufacturing, specialty chemicals, food processing, pharmaceutical production, agriculture, cosmetics, and general industrial manufacturing.

Why Choose Our Packaging Equipment

Precision Weighing and Metering :Equipped with high-accuracy load cells and intelligent metering control, our machines consistently deliver target fill weights, reducing giveaway and material loss across every production cycle.

Automation and Efficiency :Automated bag clamping, filling, weighing, and discharge sequences reduce the reliance on manual labor while accelerating output. This directly translates to reduced per-unit packaging costs and higher production throughput.

Flexible Configuration : With eight available valve port and opening type options, every machine can be adapted to match the precise requirements of your material, whether it flows freely, tends to bridge, has low bulk density, or carries moisture sensitivity.

Durable Industrial Construction : Our machines are built with industrial-grade components designed for continuous operation. Stainless steel contact-part options are available for hygiene-critical applications including food and pharmaceutical packaging.

Integrated Production Line Capability : Machines can be supplied as standalone units or as part of a complete packaging line, including conveyors, bag placers, discharge systems, and palletizing equipment.

Post-Sale Support : We provide comprehensive after-sales service, technical guidance, spare parts availability, and ongoing product improvement based on real-world operational feedback.

Technical Consultation

Selecting the right automatic metering packaging machine requires understanding both the material properties and the production environment. We encourage prospective buyers to contact our technical sales team with details about:

• Material type (powder, granule, paste, liquid)
• Target fill weight or volume range
• Required output per hour or per shift
• Bag format (valve bag, open-mouth bag, big bag/FIBC)
• Special requirements (explosion-proof, stainless steel, GMP compliance)

Our team will recommend the appropriate filling mechanism, valve port type, and system configuration — ensuring the equipment you receive is matched precisely to your operational needs.

We adhere to the principle of market-oriented, innovation-driven, quality-guaranteed manufacturing — continuously upgrading our products and services to meet the evolving demands of global industrial packaging.
