China has become a major sourcing base for high pressure injector syringes, CT/MRI contrast injector consumables, angiographic syringe kits, and pressure connecting tubes. For procurement teams, the opportunity is not simply lower unit cost—it is access to established medical-device supply chains in Shenzhen, Guangdong, Shanghai, Jiangsu, and Shandong, where manufacturers combine precision injection molding, cleanroom assembly, sterilization management, regulatory documentation, and global export logistics.
In 2025, China's medical-device exports reached USD 50.469 billion, up 3.54% year over year. Disposable medical consumables alone accounted for USD 10.911 billion of exports, while hospital diagnostic and treatment equipment exports reached USD 24.057 billion. These figures reflect a broader shift from low-cost manufacturing toward export-ready, regulated medical products and technical healthcare solutions.
This guide reviews 10 notable China-based manufacturers and suppliers relevant to high pressure injector syringes. It is designed for hospital procurement teams, regional distributors, imaging-equipment brands, and OEM buyers seeking long-term partners for CT, MRI, and DSA/angiography consumables.
High pressure injector syringes are specialized single-use medical consumables used to deliver contrast media or saline through CT, MRI, and angiography injector systems. Unlike ordinary disposable syringes, they must withstand controlled high-pressure injection, maintain stable connections, support predictable fluid delivery, and remain compatible with the mechanical interfaces of designated injector platforms.
China's strength in this category comes from the overlap of several industrial capabilities:
- Medical-grade polymer sourcing and molding.
- Precision mold engineering for syringe barrels, plungers, adapters, and connectors.
- ISO-classified cleanroom assembly.
- Ethylene oxide sterilization or validated outsourced sterilization.
- Packaging engineering for sterile barrier systems.
- Regulatory-document preparation for CE, FDA 510(k), and market-specific registration.
- Mature export infrastructure from Shenzhen, Guangzhou, Shanghai, Ningbo, and other coastal manufacturing hubs.
Guangdong—especially Shenzhen—has become a notable cluster for medical imaging consumables, contrast-delivery systems, and related patient-monitoring accessories. Major manufacturers in the region benefit from proximity to mold makers, automation suppliers, medical-device engineers, exporters, and third-party testing resources.
China's General Administration of Customs reported that exports of medical or surgical instruments and apparatuses reached USD 20.8998 billion in 2025, compared with USD 19.7135 billion in 2024, representing 6.0% growth. The China Chamber of Commerce for Import and Export of Medicines and Health Products also reported that diagnostic and treatment equipment was the fastest-growing major medical-device export category in 2025, increasing 8.11% year over year.
For buyers, this means that China can be a practical sourcing location—but only if supplier evaluation goes beyond catalog photos, low quotations, and generic certification claims.
A reliable high pressure injector syringe manufacturer should be evaluated as a regulated medical-device partner, not merely as a plastics supplier. The companies below were considered using publicly available information, regulatory records, product relevance, market presence, and manufacturing scope.
| Evaluation Area | What Buyers Should Check | Why It Matters |
|---|---|---|
| Quality system | Valid ISO 13485 certificate, certificate scope, issuing body, factory address | Confirms that the quality-management system covers relevant medical-device activities |
| Regulatory history | CE documentation, FDA 510(k) records where applicable, product registration evidence | Indicates experience with regulated international markets |
| Product relevance | CT, MRI, DSA, angiographic syringe kits, tubing, transfer sets, injector compatibility | Avoids choosing a general syringe factory with limited high-pressure expertise |
| Manufacturing depth | Molding, tooling, assembly, sterilization, packaging, testing | Greater vertical control can reduce supply-chain and consistency risks |
| Technical validation | Pressure resistance, leak testing, connection testing, biocompatibility, shelf-life validation | High-pressure consumables must perform consistently under defined operating conditions |
| OEM/ODM capability | Custom tooling, private-label packaging, IFU localization, compatibility development | Essential for distributors and imaging-equipment brands |
| Delivery reliability | Capacity planning, safety stock, lot traceability, export documentation | Important for hospital tenders and recurring distribution programs |
| Communication quality | Engineering response, documentation speed, sample coordination, change-control process | A major predictor of long-term sourcing success |
A high pressure injector syringe is not defined only by transparency or barrel appearance. Professional buyers should assess the complete system:
- Medical-grade polypropylene or other validated resin for the syringe barrel.
- Appropriate elastomeric materials for seals and plunger components.
- Controlled molding parameters to minimize flash, sink marks, internal stress, and dimensional variation.
- Secure luer-lock, proprietary, or system-specific connection geometry.
- Consistent plunger movement and sealing performance.
- Pressure and leakage testing that reflects the intended clinical use.
- Sterile barrier packaging that maintains integrity during shipping and storage.
- Clear compatibility statements tied to specific injector brands and models.
For angiographic applications, the U.S. FDA classifies angiographic injectors and syringes under 21 CFR 870.1650, generally as Class II devices under product code DXT. This does not mean every syringe or connector is automatically approved for every market; it means buyers must assess the product's regulatory pathway and evidence carefully.

Due-diligence point
Treat general syringe-manufacturing credentials and high-pressure imaging-consumables expertise as separate qualifications. Only approve a supplier after reviewing high-pressure-specific validation evidence.
Actual capacity, minimum order quantity, and delivery terms can vary substantially by SKU, sterilization method, packaging format, private-label requirement, and destination-market documentation. The table below is a practical screening framework rather than a substitute for supplier quotations.
| Manufacturer | Main Strength | Typical Product Scope | Public Regulatory Signals | Estimated Order Fit | OEM/ODM Suitability |
|---|---|---|---|---|---|
| MAIWEI INC. | Flexible imaging-consumables specialist | CT/MRI/DSA syringes, connecting tubes, transfer sets, accessories | ISO 13485, CE, FDA 510(k) stated; K253048 public record | Small-to-medium and scalable programs | High for private label, packaging, kits, and customized support |
| Shenzhen Antmed | Integrated scale and broad portfolio | Injectors, high-pressure syringes, tubing, transducers, imaging systems | ISO 13485, MDSAP, FDA 510(k), multiple market registrations stated | Medium-to-large volume | Medium-to-high, subject to project scope |

| Wuxi supplier associated with K152906 | Jiangsu geographic alternative | Disposable high-pressure injector syringes | FDA K152906 | Medium-to-large volume | To be verified |
| Shenzhen Baoan Medical Supplies | Sterile angiographic syringe experience | Sterile high-pressure angiographic syringes | FDA K182289 and related records | Medium volume | Medium |
| Shanghai Kindly Medical Instruments | Broad disposable-device background | Multi-category medical disposables | FDA regulatory history | Large-volume potential | To be verified |
| Shandong Zibo Shanchuan | Syringe-manufacturing heritage | Syringes and related medical products | FDA syringe documentation | Component or standard-syringe projects | To be verified |
When a supplier advertises a monthly capacity figure, buyers should ask exactly what that number represents. "10 million units per month" may refer to unsterilized molded parts, not finished sterile syringe kits. A reliable comparison requires consistent definitions.
Ask each supplier to separate:
- Molded syringe barrels per month.
- Finished assembled syringe kits per month.
- Sterilized finished kits per month.
- Available capacity after committed orders.
- Peak-season capacity.
- Current lead time for standard SKUs.
- Lead time for new private-label packaging.
- Maximum annual capacity by product family.
- MOQ for standard packaging.
- MOQ for printed private-label packaging.
- MOQ for custom molded components.
MOQ is not fixed across the industry. It usually depends on packaging, sterilization, product type, and customization level.
| Purchase Type | Common Procurement Pattern | Main Cost Driver |
|---|---|---|
| Standard compatible syringe kit | Lower MOQ may be possible if stock exists | Existing inventory and standard packaging |
| Distributor private label | Higher MOQ than stock products | Printed carton, pouch artwork, labeling, and regulatory review |
| Custom kit configuration | Moderate-to-high MOQ | New BOM, validation, packaging changes |
| New molded syringe design | High MOQ and project commitment | Mold tooling, engineering validation, biocompatibility, testing |
| Country-specific registered product | Depends on registration plan | Documentation, local representation, label and IFU requirements |
A supplier that cannot explain these differences clearly may not have mature OEM project management.
Most high pressure injector syringe barrels are manufactured from medical-grade polymers, commonly polypropylene or other validated resins selected for mechanical performance, molding behavior, transparency requirements, chemical compatibility, and sterilization conditions.
However, "medical-grade PP" is not enough information. Buyers should ask:
- What is the exact resin grade and producer?
- Is the resin traceable by batch?
- Does the supplier maintain incoming-material inspection records?
- Is the resin formulation changed without customer notification?
- Has the material been validated for contact with the intended contrast media or saline?
- Is there a documented change-control process for resin, colorant, lubricant, or seal material changes?
A lower-cost supplier may use a visually similar resin that performs differently under pressure, sterilization, or long-term storage. This risk is especially relevant when syringes are shipped internationally and stored for extended periods in hot or humid environments.
High-pressure imaging consumables should be evaluated as a system, not as a separate syringe body. Performance depends on:
- Syringe barrel wall thickness.
- Plunger seal design.
- Connector geometry.
- Tubing construction.
- Bonding or assembly method.
- Pressure rating.
- Injection profile.
- Contrast-media viscosity.
- Injector model.
- Temperature conditions.
- User handling.
The buyer should request pressure testing that reflects the actual intended application. A generic burst-pressure statement is less valuable than a full test protocol showing test pressure, hold time, sample quantity, acceptance criteria, and failure mode.
For sterile single-use products, packaging is part of the medical device. Important questions include:
- Is sterilization performed in-house or by a qualified external provider?
- Is ethylene oxide residual testing available where relevant?
- What sterile barrier system is used?
- Is the packaging validated for transportation and shelf life?
- Is there an aging study supporting the stated shelf life?
- Can the supplier provide package-integrity validation?
- Are carton markings suitable for the destination market?
Antmed, for example, states that it has ISO 11135 ethylene oxide sterilization service certification, in addition to ISO 13485 and MDSAP certification. This type of vertical capability can be valuable, but all buyers should still verify documentation against the specific product and site.
"Compatible with Brand X" should never be accepted as a casual marketing phrase. It is a technical and regulatory claim that should be supported by documented fit, pressure, functional, and risk-based evaluation.
Buyers should request:
- Exact injector brand and model number.
- Syringe volume and configuration.
- Connection interface drawings.
- Functional test results.
- Pressure and leakage data.
- User instructions.
- Compatibility statement signed by the manufacturer.
- Evidence that the supplier has not changed the connection design after validation.
Many factories can produce basic disposable syringes. Far fewer can reliably manufacture validated high-pressure injector syringe systems for CT, MRI, or angiography workflows.
How to avoid it
Ask for injector-specific product drawings, pressure-test records, sterilization validation, compatible-model lists, and samples for functional evaluation. If a supplier only sends a generic syringe catalog, it is not enough.
A supplier may provide an ISO 13485 certificate that is genuine, but the certificate scope may cover a different product category or a different factory location.
How to avoid it
Verify:
- Certificate number.
- Issuing certification body.
- Validity date.
- Factory name and address.
- Scope wording.
- Accreditation details.
- Whether the scope includes design, manufacturing, sterilization, or only distribution.
For U.S.-market claims, search the FDA 510(k) database by company name, product name, and 510(k) number. FDA records, for example, show the regulatory listing for MAIWEI's high pressure syringe and accessory product family under K253048.
A low syringe price can conceal missing items such as quick-fill tubes, transfer spikes, check valves, J-tubes, pressure connecting tubes, clamps, or packaging components.
How to avoid it
Request a full bill of materials and a product photograph of the exact kit configuration. Confirm whether the quoted unit is:
- Syringe only.
- Syringe plus plunger.
- Syringe plus tubing.
- Complete sterile kit.
- Kit with all necessary transfer components.
- Individually packed unit.
- Bulk-packed non-sterile component.
Two products may look similar but differ in locking geometry, volume accuracy, plunger force, tubing connection, or injector recognition interface.
How to avoid it
Do not approve a product based on photographs. Test the exact supplied lot on the intended injector under controlled conditions, following the device manufacturer's instructions and the buyer's internal quality procedures.
The most expensive failures often occur after import: cracking, stiffness, leakage, yellowing, poor transparency, seal degradation, or inconsistent plunger movement.
How to avoid it
Require resin traceability, incoming-material controls, lot-level quality documents, and retained samples. Include material-change notification requirements in the supply agreement.
The most overlooked risk is not the syringe barrel—it is the interface stack.
In real clinical use, failure may occur at the interaction between syringe, tubing, transfer set, connector, injector head, and user assembly sequence. A high-pressure syringe can pass an individual pressure test but still create risk when paired with a poorly controlled connector or a substitute tubing component.
This is why experienced buyers should not approve:
- A syringe from Supplier A.
- A connecting tube from Supplier B.
- A transfer spike from Supplier C.
…unless the complete assembled configuration has been tested as a system.
A practical rule is: Qualify the final clinical kit, not just the individual components.
For example, if a distributor buys a 200 mL CT syringe from one factory and a pressure connecting tube from another to reduce cost, the combined system may have no documented validation for connector engagement, leakage, pressure cycling, or user handling. The distributor—not the original suppliers—may then carry the responsibility for the combined configuration in its destination market.
Before contacting suppliers, prepare a clear technical brief:
- CT, MRI, DSA, or angiography application.
- Injector brand and exact model.
- Syringe volume and head configuration.
- Required tubing length and connector type.
- Transfer set or quick-fill tube requirement.
- Sterility requirement.
- Packaging format.
- Target-country regulations.
- Expected annual volume.
- Desired branding and language requirements.
- Required documentation.
Create a shortlist of three to five suppliers. Include at least:
- One specialized imaging-consumables manufacturer.
- One large integrated manufacturer.
- One alternative regional supplier.
- One potential OEM/private-label partner.
This protects your business from single-source risk and provides a meaningful benchmark for pricing, lead times, and documentation quality.
The supplier's technical pack should include:
- Company registration information.
- ISO 13485 certificate.
- CE documentation where relevant.
- FDA 510(k) documentation where relevant.
- Product datasheet.
- Intended-use statement.
- Injector compatibility list.
- Sterilization information.
- Pressure-test report.
- Biocompatibility information.
- Packaging specification.
- Shelf-life report or aging-validation summary.
- Sample certificate of analysis or certificate of conformity.
- Product images and full kit BOM.
- Instructions for use.
Do not accept only pre-production or hand-assembled samples when placing a significant order. Ask whether samples come from normal production lots.
Evaluate:
- Visual appearance.
- Marking clarity.
- Packaging integrity.
- Connection fit.
- Plunger action.
- Tubing flexibility.
- Leakage resistance.
- Lot traceability.
- Documentation consistency.
For high-value or regulated procurement programs, use one of these approaches:
- On-site factory audit.
- Remote video audit with live walkthrough.
- Independent third-party audit.
- Pre-shipment inspection.
- First-article verification.
- Batch sampling by a qualified quality-control team.
The audit should inspect not only the finished-goods warehouse but also resin storage, mold maintenance, cleanroom controls, assembly lines, packaging, sterilization release, and batch-record systems.
Your supply agreement should require written notification before changes to:

High pressure injector syringe kits are relatively lightweight but can occupy significant carton volume. Freight planning should consider both unit cost and volumetric weight.
- Use export cartons designed to protect sterile barrier packaging.
- Confirm carton dimensions, gross weight, and pallet configuration before booking freight.
- Check whether the product requires temperature control during transit and storage.
- Confirm shelf-life remaining upon shipment; many buyers require a minimum remaining shelf-life percentage.
- Ensure labels include lot number, expiration date, storage conditions, and destination-market language requirements.
- Confirm whether the supplier can provide CE-related documents, declaration of conformity, Free Sale Certificate where applicable, certificate of origin, and legalized documents if needed.
- Clarify Incoterms early: EXW, FOB, CIF, DAP, or DDP arrangements create very different risk and cost responsibilities.
In medical consumables, a delayed shipment can affect a distributor's tender commitments or a hospital's imaging workflow. Buyers should evaluate not only the quoted lead time but also:
- On-time delivery performance.
- Safety-stock policy.
- Forecast-sharing process.
- Emergency production capacity.
- Raw-material inventory.
- Sterilization turnaround time.
- Export-document turnaround.
- Response time for quality complaints.
China offers a wide range of high pressure injector syringe suppliers, from large vertically integrated manufacturers to flexible specialized partners. The right choice depends on more than price. Buyers should match the supplier to their required injector compatibility, regulatory market, annual volume, private-label needs, desired documentation depth, and expected service level.
For large, broad, multi-country sourcing programs, integrated manufacturers such as Antmed may be attractive because of their scale, wide product range, and global-market infrastructure. For buyers seeking responsive support, imaging-consumable specialization, OEM flexibility, and customized service for small-to-medium distribution programs, MAIWEI INC. is a practical supplier to include in the qualification process.
The most reliable sourcing strategy is to shortlist several manufacturers, compare their documentation quality, verify the factory and certification scope, test production-representative samples, and approve the full syringe-and-tubing system—not just individual components.
If you are sourcing CT, MRI, or angiographic high pressure injector syringe kits, contact MAIWEI INC. with your injector model, annual volume, target market, and branding requirements to request a compatibility review, product documentation package, and sample proposal.
Check the certificate number, issuing body, validity dates, factory address, and certification scope. Then contact the issuing certification body or use its public certificate-validation platform if available. Confirm that the listed factory is the same legal manufacturer shown on the product label and export documents.
Do not rely on a scanned PDF alone. Ask whether there have been changes to the factory address, certificate scope, or quality-management system since the certificate was issued.
No. A 510(k) clearance applies to a specific device submission and does not automatically cover every product variant, packaging format, manufacturing change, or private-label arrangement. Buyers should confirm the exact 510(k) number, device name, legal manufacturer, indication for use, product code, and current regulatory responsibilities.
For example, FDA records identify high-pressure angiographic syringe products under the Class II angiographic injector and syringe category, product code DXT.
Request written compatibility confirmation for the exact injector manufacturer, model, syringe volume, and configuration. Then conduct an internal evaluation using samples from a normal production lot. Review fit, locking mechanism, plunger movement, leakage performance, pressure behavior, and workflow usability.
Never assume that visual similarity equals compatibility.
At minimum, request the product specification, lot number, certificate of conformity, sterilization information, pressure-test summary, package specification, compatibility list, instructions for use, and a copy of applicable quality certificates.
For a serious OEM project, also request material declarations, biocompatibility summary, shelf-life information, risk-management summary, and change-control policy.
It can be possible, but it increases technical and regulatory risk. The syringe, tube, connector, transfer set, and injector interface should be evaluated as a complete system. If you combine components from different suppliers, you should conduct system-level testing and clarify who is responsible for the final assembled kit.
For most distributors, sourcing a validated complete kit from one qualified manufacturer is the lower-risk approach.
