Plastic Syringe Filling and Capping
For liquid or ointment filling into nominated plastic syringe and cap formats. The source document lists a 0.5–50 ml range and 3 kW total power.
Compare four HIJ syringe filling machine platforms by syringe system, closure method, filling needles and published output. Final selection is based on your formulation, components, format range, cleanroom boundary and FAT acceptance method.




The first decision is whether the project uses a plastic syringe and cap or an SCF glass syringe and stopper. The second is whether one or two filling needles are justified by the required accepted output and product trial.

For liquid or ointment filling into nominated plastic syringe and cap formats. The source document lists a 0.5–50 ml range and 3 kW total power.

For a higher published output on compatible plastic syringe projects. The source document lists 1–50 ml, with mold or pump changes required for some formats and dose ranges.

For nominated SCF glass syringe and stopper formats. The source document lists grouped manual loading, automatic filling, vacuum stoppering and automatic discharge.

Two-needle vacuum filling and stoppering for confirmed SCF glass syringe formats. The source document lists 3 kW total power and an optional automatic nest remover.
These values come from the four named product documents and apply to the listed platform only. They are screening references. The approved proposal must identify the actual product, components, utilities, options and test conditions.
| Model | Syringe and closure route | Published sizes | Needles | Published capacity | Accuracy reference | Total power |
|---|---|---|---|---|---|---|
| HIJ-DZA100 | Plastic syringe filling and capping | 0.5–50 ml | 1 | 1,800–2,100 p/h | ≤±1–2% | 3 kW |
| HIJ-DZA200 | Plastic syringe filling and capping | 1–50 ml; mold and pump range must be confirmed | 2 | 3,000–3,900 p/h | ≤±1–2% | 8.5 kW |
| HIJ-GZB100 | SCF glass syringe vacuum filling and stoppering | 0.5, 1, 2.25, 3, 5, 10 and 20 ml; not universal | 1 | 600–800 p/h | ≤±1–2% | 2.5 kW |
| HIJ-GZB200 | SCF glass syringe vacuum filling and stoppering | 0.5, 1, 2.25, 3, 5, 10 and 20 ml; not universal | 2 | 800–1,200 p/h | ±1–2% | 3 kW |
Use the component path first. A plastic syringe cap and an SCF glass syringe stopper need different handling, feeding and closure systems. Needle count comes after the process route has been fixed.
Use this route when the required process is quantitative filling followed by plastic cap feeding and capping. DZA100 is the one-needle reference. DZA200 is the two-needle reference for a higher published throughput.
Use this route when the nominated SCF glass syringe and elastomeric stopper require filling and vacuum stoppering. GZB100 uses one filling needle; GZB200 uses two.
A useful syringe filling system specification follows each component and product contact from infeed to accepted discharge. It also states which steps are automatic, optional or supplied by the buyer.
Define bulk, grouped, tub-and-nest or another controlled presentation. GZB100 documentation lists grouped manual loading; automatic nest removal is a separate option.
Define the supply vessel, transfer path, temperature, mixing or heating need, hold-up and cleaning boundary before selecting the filling assembly.
The four source documents list ceramic plunger-pump filling. Confirm the pump range, filling needle, fill profile and test method with the actual formulation.
DZA machines feed and apply plastic caps. GZB machines use the confirmed stopper system and vacuum stoppering route. Define presence and position limits.
State required checks, rejected-unit handling, data records and the physical handoff to rod insertion, labeling or secondary packaging.

A photograph can start a discussion, but it cannot prove component handling or fill performance. The engineering review needs the nominated syringe and closure system together with the actual product or a justified representative medium.
“Liquid or ointment” is a starting category, not a complete filling specification. A pharmaceutical syringe filling machine must be reviewed against the actual material behavior and the permitted process window.
State viscosity or rheology at filling temperature, foaming tendency, entrained air, settling and time-dependent behavior. These inputs affect the vessel, transfer path, pump range, needle and fill profile.
List every target dose. Define whether accuracy is assessed by mass or volume, the sample count, start-up treatment, calculation and acceptance limit. Do not treat the source-document percentage as a universal result.
Define product-contact materials, cleaning method, drainage, disassembly, changeover sequence and required evidence. Different products or dose ranges may require separate pump assemblies or format parts.
The source documents describe modular equipment that can run as a standalone syringe filler or connect to other functions. Only modules named, engineered, priced and tested in the contract belong to the delivered line.
Confirm manual grouped loading, automatic syringe feeding or automatic nest removal. Include tub opening, liner removal and transfer only when they are explicitly in scope.
Define whether the buyer or supplier provides the vessel, stirring, heating, product transfer, level control and connection hardware. State the battery limit for utilities and cleaning.
Plastic caps and elastomeric stoppers require different feeding and placement systems. Record closure orientation, replenishment, low-level handling, presence checks and rejects.
Optional laminar-flow hoods appear in the source documents. Airflow, filtration, monitoring, room integration and qualification must be defined for the specific project.
Plunger-rod insertion, labeling, coding and label inspection are downstream options, not automatic inclusions in the base filling machine.
Define tray handling, blister packaging, cartoning, aggregation or case packing as separate interfaces with their own speeds, inspections and acceptance criteria.
If the search is for an aseptic syringe filling machine, the equipment is only one part of the control strategy. The URS must identify component preparation, product path, intervention design, environmental boundary, monitoring, cleaning, sterilization or decontamination responsibilities, alarms, data and site qualification.

Compare evidence and project boundaries instead of company claims. Give every shortlisted manufacturer the same controlled inputs, then check whether the proposed machine, options and acceptance plan answer those inputs line by line.
Ask which document supports each capacity, size, accuracy, utility and material statement. Confirm that a value belongs to the offered model rather than another machine in the supplier’s range.
Separate the base filler, format parts, product-supply equipment, closure handling, clean-air options, inspection, downstream modules, documentation and site activities. Record exclusions beside inclusions.
Require the same production-intent components, product condition, run duration, sampling plan and defect criteria. A demonstration video or short water run is not equivalent to an agreed FAT.
Also define how drawings, software or recipe revisions, spare and wear parts, manuals, training, remote support and open items will be controlled. These details influence lifecycle risk even when two quotations show a similar headline machine price.
A useful quotation is based on the complete process and acceptance boundary. A base-machine price cannot be compared fairly when another proposal includes additional formats, product preparation, clean-air equipment, inspection, documentation or downstream automation.
Plastic capping versus SCF glass vacuum stoppering and one versus two filling needles establish the first equipment boundary.
Additional syringe sizes, closures, molds, guides and pump assemblies change the mechanical and validation scope.
Heating, mixing, level control, transfer, defoaming or special product-contact requirements must be defined and tested.
Automatic feeding, denesting, rod insertion, labeling, coding and secondary packaging add equipment and interfaces.
Fill verification, visible-air inspection, closure checks, rejection, audit-trail or data-integration requirements affect design and testing.
Document language, drawings, material records, FAT, SAT, qualification support, training and site services must be itemized.
The quotation, design review and factory acceptance test should use the same controlled inputs. This prevents a headline specification from becoming an acceptance dispute after the machine is built.
| Acceptance topic | Define before FAT | Evidence to record | Common ambiguity to remove |
|---|---|---|---|
| Output | Accepted units per hour, run duration, planned stops and reject rule | Total units, accepted units, rejects, stop log and operating time | Mechanical rate versus accepted production output |
| Fill amount | Target, tolerance, mass or volume method, sample size and calculation | Individual results, summary calculation, instruments and conditions | “Accuracy” without a measurement protocol |
| Visible air | Defect definition, lighting or instrument, sample condition and limit | Challenge samples, inspection results and deviations | Undefined “bubble-free” wording |
| Closure | Presence, position, insertion or capping criteria and reject response | Measured samples, defect challenge and rejection record | Visual appearance without an agreed limit |
| Recovery | Permitted operator interventions and restart checks | Alarm, stop, correction, line clearance and restart record | A successful uninterrupted short demonstration |
These answers separate published model references from the product, component and acceptance evidence still required for a project decision.
Share your product, syringe, cap or stopper, fill range, accepted output, line boundary and FAT criteria. HIJ can review the four platforms and prepare an itemized technical scope for your project.
