DTNX-60YA
ZUNGWAN
The DTNX-60YA is an automatic double-head filling, stoppering, and capping machine for eye drop bottles with a published filling range of 2–20ml.
The machine combines metered liquid filling, inner-stopper placement, outer-cap placement, and capping in one compact packaging process. Its double-head filling arrangement uses microcomputer-controlled pump steps to set the required dose.
Peristaltic pumps are used for standard configurations, while ceramic pumps are available for selected applications. A pick-and-place mechanism transfers stoppers and caps to the bottle, reducing manual contact during the packaging process.
The published filling accuracy is within ±1%, with stoppering and capping rates of at least 99%. Actual performance depends on the liquid, pump configuration, target volume, bottle dimensions, stopper and cap tolerances, and operating speed.
The machine can be configured for eye drop solutions and other compatible small-volume liquid products. Final pharmaceutical use must be evaluated according to the customer’s process, hygiene, validation, and regulatory requirements.
Empty bottles enter the machine through the configured feeding and conveying system. Bottle spacing and positioning components guide each container to the filling station.
Bottle handling should be matched to:
Bottle diameter
Bottle height
Neck dimensions
Bottle material
Bottom stability
Opening position
The product page does not define whether an automatic bottle unscrambler is included. Bottle feeding should therefore be confirmed as part of the final line configuration.
Two bottles can be filled during each machine cycle using the double-head dosing system.
The operator sets the pump-step parameters according to the required filling volume. During commissioning, these settings are verified using the actual eye drop solution, bottle, tubing, and production speed.
After filling, an automatic pick-and-place mechanism transfers the inner stopper into the bottle opening.
Correct insertion depends on the dimensional consistency of the bottle neck and stopper. The machine tooling should be manufactured using approved samples rather than nominal dimensions alone.
The machine places the outer cap over the bottle after the stopper has been inserted. Cap orientation and feeding stability depend on the cap shape, height, diameter, thread, and surface characteristics.
The capping station tightens or secures the outer cap according to the closure design.
Capping performance should be assessed using:
Applied torque
Cap height
Thread engagement
Seal integrity
Bottle deformation
Cap damage
Opening performance
The required capping method and torque-control mechanism should be confirmed for the final machine.
Completed bottles leave the machine for inspection, labeling, coding, cartoning, or other downstream packaging operations.
The DTNX-60YA uses microcomputer-controlled pump steps to set the amount dispensed during each filling cycle.
The relationship between the step setting and actual volume depends on:
Pump type
Tube or pump-chamber dimensions
Liquid viscosity
Product temperature
Filling speed
Suction conditions
Nozzle design
Tubing condition
The required dose should be confirmed through calibration rather than relying only on a theoretical step value.
Each filling head should be checked separately because small differences in tubing, pump compression, pipe length, or nozzle response can affect delivery.
A recommended calibration process includes:
Install the approved product-contact components.
Prime the liquid path.
Set the initial pump parameters.
Fill a defined sample quantity.
Measure each filled bottle independently.
Adjust the applicable head.
Repeat the test at production speed.
Record the approved settings.
Calibration frequency should be defined by the customer’s quality system.
The published filling precision is no more than ±1%.
Before this figure is used as an acceptance criterion, the technical agreement should define:
Target filling volume
Test liquid
Test temperature
Number of samples
Measurement method
Production speed
Warm-up or priming conditions
Permitted statistical range
Low filling volumes are generally more sensitive to pump, tubing, and measurement variation.
The standard description refers to peristaltic pump filling. In a peristaltic system, the liquid remains inside the pump tubing and does not directly contact the pump’s mechanical drive components.
Potential advantages include:
Defined product-contact path
Convenient tubing replacement
Reduced pump-component contact
Suitability for many low-viscosity liquids
Easier product-path changeover
Performance depends on tube material, internal diameter, wall thickness, compression, speed, and service life.
Tubing should be selected for chemical compatibility, extractables requirements, sterilization method, and the customer’s pharmaceutical process.
A ceramic pump can be considered for applications requiring a rigid metering chamber or different dosing characteristics.
Before selecting a ceramic pump, confirm:
Product compatibility
Filling volume
Required accuracy
Liquid viscosity
Presence of particles
Cleaning process
Sterilization method
Seal and valve configuration
The ceramic-pump option should be evaluated with the actual liquid because pump selection affects both filling performance and cleaning procedures.
A peristaltic pump may be preferred when a replaceable tubing pathway is important. A ceramic pump may suit projects requiring a different metering principle or where the product is compatible with the pump materials.
The selection should be made from product tests rather than from the filling volume alone.
The original page describes a mechanical-hand structure for transferring the inner stopper and outer cap.
A more precise description is a pick-and-place mechanism that removes a closure from the feeding position and places it onto the bottle.
This process helps coordinate:
Stopper pickup
Stopper alignment
Stopper insertion
Cap pickup
Cap placement
Transfer to the capping station
Automatic stopper handling typically requires an orienting and feeding system. The exact bowl feeder, track, chute, or loading method should be confirmed in the final configuration.
Stopper feeding depends on:
Shape
Diameter
Height
Flexibility
Surface friction
Static electricity
Manufacturing tolerance
The outer cap must be correctly oriented before placement. Cap samples should be tested for feeding stability, thread engagement, deformation, and surface scratching.
The product page lists both stoppering and capping rates at ≥99%.
These rates should be defined using an agreed test duration and approved packaging components. Damaged, deformed, contaminated, or dimensionally inconsistent closures can affect actual production performance.
The machine’s published filling range is 2–20ml, but filling volume alone does not confirm bottle compatibility.
Customers should provide:
Bottle drawing
Bottle material
Bottle diameter
Bottle height
Neck dimensions
Inner-stopper drawing
Outer-cap drawing
Thread specification
Physical bottle samples
Closure samples
The machine may be configured for compatible glass or plastic eye drop bottles. Each container type requires appropriate guides, holders, transfer parts, and closure tooling.
The page does not provide a universal bottle-size range. Compatibility must therefore be confirmed using actual samples.
Using more than one bottle size may require replacement or adjustment of:
Bottle guides
Positioning components
Filling nozzles
Stopper tooling
Cap tooling
Feeding tracks
Pick-and-place grippers
The required changeover time and tool list should be confirmed during project design.
The product-contact pathway may include:
Product tank or supply vessel
Pump tubing or ceramic pump
Connecting pipes
Valves
Filling nozzles
Seals and fittings
Materials should be selected according to the eye drop formulation, cleaning agents, sterilization method, and applicable pharmaceutical requirements.
The original page does not identify the stainless-steel grade, tubing material, surface finish, or seal material. These should be included in the technical agreement.
A typical cleaning process may involve:
Removing the remaining liquid safely.
Disassembling applicable product-contact parts.
Cleaning with an approved solution.
Rinsing according to the process requirement.
Drying or sterilizing the components.
Inspecting the product path.
Reassembling the filling system.
Performing calibration before production.
The DTNX-60YA should not be described as having automatic CIP or SIP unless those systems are specifically included.
Peristaltic tubing changes with use because of repeated compression. A replacement interval should be established based on the tubing manufacturer’s data, product compatibility, operating speed, and validation results.
The machine uses microcomputer-based control for setting pump steps and coordinating the packaging process.
Depending on the ordered configuration, the control system may manage:
Filling parameters
Pump operation
Bottle transfer
Stopper placement
Cap placement
Capping operation
Manual setup
Alarm handling
Production count
The availability of recipe storage, batch records, user-access levels, audit trails, or electronic records must be confirmed separately.
Before production:
Verify the bottle and closure tooling.
Install the correct filling pump and product path.
Check the electrical and pneumatic supplies.
Prime the liquid circuit.
Set the preliminary filling parameters.
Calibrate both filling heads.
Test stopper feeding and insertion.
Test cap placement and capping.
Inspect filled and closed samples.
Approve the operating settings.
The equipment performs packaging operations, but pharmaceutical quality control still requires defined inspection procedures.
Potential checks include:
Filling volume or weight
Visible particles
Bottle cleanliness
Stopper insertion depth
Missing stopper
Cap presence
Capping torque
Leakage
Bottle damage
Label and code verification
The required sampling plan and acceptance criteria should be defined by the customer.
Optional inspection devices may be required if automatic rejection of defective bottles is expected.
The original page states that the machine meets new GMP requirements. For a regulated pharmaceutical project, a more accurate description is that the equipment can be configured to support a GMP-oriented packaging process.
Final compliance depends on:
Machine design
Contact materials
Cleanability
Production environment
Customer procedures
Qualification documents
Process validation
Operator training
Maintenance and calibration
The machine alone cannot make a complete production process GMP-compliant.
For cleanroom installation, confirm:
Machine surface materials
Particle-control requirements
Cleaning access
Lubricant isolation
Cable and air routing
Exhaust requirements
Laminar airflow compatibility
Machine footprint
Maintenance access
A laminar airflow enclosure or isolator is not described as standard equipment and should be evaluated separately where required.
The current product information does not define the machine as an aseptic filling system. Sterile or aseptic use requires a separate assessment of the product path, environmental controls, component sterilization, operator intervention, and validation strategy.
The DTNX-60YA can be integrated with upstream and downstream pharmaceutical packaging equipment.
A complete line may include:
Bottle unscrambling or loading
Bottle washing
Drying or sterilization
Eye drop filling
Inner-stopper insertion
Outer-cap placement
Capping
Leak or closure inspection
Labeling
Coding
Cartoning
Case packing
Line design should define conveyor height, operating direction, speed synchronization, accumulated bottle handling, alarm interlocks, and rejection logic.
Overall line output is determined by the slowest connected process.
The DTNX-60YA is primarily intended for:
Eye drop solutions
Ophthalmic liquid products
Compatible small-dose pharmaceutical liquids
Selected sterile or non-sterile liquids after process assessment
It should not be promoted for all pharmaceutical liquids without reviewing viscosity, foaming, particles, chemical compatibility, filling volume, cleaning, and sterility requirements.

For project evaluation, customers should provide the liquid information, target volume, bottle, stopper, cap, packaging drawings, required output, applicable production standard, and cleaning requirements.
It performs liquid filling, inner-stopper insertion, outer-cap placement, and capping. Upstream bottle washing and downstream labeling or cartoning require separate equipment unless included in the project.
The published filling range is 2–20ml. Accuracy and output should be verified at the customer’s actual target volume.
The double-head design allows two bottles to be filled during each applicable machine cycle. The actual output depends on the complete packaging sequence and product conditions.
A peristaltic pump moves the liquid through replaceable tubing. A ceramic pump uses a rigid metering structure. Selection depends on the liquid, required accuracy, cleaning method, and process requirements.
The machine may form part of a sterile packaging process, but the current page does not define it as a complete aseptic filling system. Sterile use requires environmental controls, validated product paths, component sterilization, and process qualification.
It can be customized for approved bottle formats. Different bottles, stoppers, or caps may require additional tooling and change parts.
The published accuracy is within ±1%. The acceptance test should define the target volume, liquid, speed, sample size, and measurement method.
They describe the published successful closure-placement rates. The exact test duration, sample quantity, bottle quality, and closure tolerances should be defined during acceptance testing.
A bottle unscrambler is not identified as standard equipment on the page. Confirm whether bottles are fed manually or by an optional automatic feeding system.
The page makes a GMP-related claim, but compliance applies to the complete design, installation, procedures, qualification, and validated production process. Required GMP documents and design features should be specified in the project agreement.
Provide the eye drop solution or a representative test liquid, empty bottles, inner stoppers, outer caps, technical drawings, target volume, required output, and cleaning requirements.
The published requirements are 220V/50Hz power and compressed air at 0.4–0.8MPa with consumption of approximately 2m³/h. Electrical phase and air-quality requirements should be confirmed.
