Medical Supplies Plastic Injection Molds Manufacturers

We specialize in custom injection molds for medical supplies, with applications ranging from surgical instruments and infusion connectors to respiratory masks and in-vitro diagnostic (IVD) consumables. Our manufacturing process utilizes high-speed milling and mirror-finish EDM, employs premium corrosion-resistant steels, and incorporates multi-cavity hot runner designs. We provide comprehensive services, including DFM (Design for Manufacturability) reviews, mold trial process validation, full-dimensional inspection reports, and full-lifecycle maintenance and refurbishment. Key advantages include superior molding stability, exceptional mold durability, and a structural design free of cleaning dead zones—effectively ensuring a sterile production environment while reducing total cost of ownership.

Shanghai Pingzhou Plastic Products Co., Ltd.

Our company is an integrated solution provider specializing in injection mold design and manufacturing as well as plastic injection molding. We are committed to offering end‑to‑end services—from product development, mold design, and tooling fabrication to production injection molding—for customers in the medical, consumer goods, automotive, home appliance, and electronics sectors.

As China Medical Device Plastic Injection Molding Manufacturers and Medical Micro Injection Molding Parts Suppliers, we maintain a comprehensive in‑house machining chain, equipped with high‑precision CNC machining centers, EDM (Electrical Discharge Machining), wire EDM (WEDM), precision grinders, CNC lathes, milling machines, deep‑hole drilling machines, and other mold‑making equipment. Our injection molding workshop houses more than 20 injection molding machines with various clamping‑force tonnages, covering a wide molding range from small precision components to medium‑ and large‑sized structural parts. These are complemented by auxiliary peripheral equipment such as mold temperature controllers, centralized material feeding systems, and automated robotic pick‑and‑place units. This robust infrastructure gives us the proven capability to design, develop, and manufacture medium‑ to high‑precision injection molds, as well as to undertake high‑volume production orders.

Backed by an experienced team of mold structure and process design engineers, we leverage the vertical integration advantage of integrated tooling and molding to significantly shorten the lead time from product development to mass production, while effectively reducing overall costs for our customers.

Upholding the philosophy of “Customer First, Continuous Improvement” Shanghai Pingzhou Plastic Products Co., Ltd. looks forward to providing partners across various industries with cost‑effective, rapidly responsive solutions for plastic products and injection molds.

Medical Supplies Injection Molds Industry knowledge

Medical Supplies Injection Molds

As a Medical Supplies Injection Molds manufacturer, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.

Shanghai Pingzhou Plastic Products Co., Ltd. is a Medical Supplies Injection Molds manufacturer and supplier based in Shanghai, China. We design and build custom injection molds for medical devices and consumables, including syringes, infusion connectors, and test tubes. Our integrated factory—covering mold design, precision machining, and injection molding—supports projects from DFM review to high-volume production.

Our Range of Medical Molds

We offer a focused range of medical molds, each engineered for specific clinical and production requirements. The table below summarizes our standard offerings and their typical applications.

Mold Type Materials Key Features Applications
Medical Syringe Injection Molds PP, PC, COP/COC High transparency, thin-wall capability, 32-48 cavity options Disposable syringes, pre-filled syringes, insulin pens
Infusion Connectors Injection Molds PC, PE, TPE Complex flow channels, leak-proof sealing, needle-free options IV lines, hemodialysis, anesthesia systems
Medical Test Tubes Injection Molds PP, PET Uniform wall, clear graduations, -80°C resistance Blood collection, PCR, sample storage

Engineering and Manufacturing Approach

We combine in-house mold design with a full machining chain—CNC, EDM, wire EDM, precision grinding—and more than 20 injection molding machines. This vertical integration allows us to control quality at every step and reduce lead times from design to mass production.

  • DFM Review: We analyze your part design for manufacturability, suggesting improvements to wall thickness, gating, and cooling to avoid defects.
  • High-Precision Machining: Our equipment achieves tolerances up to ±0.01mm, essential for medical components.
  • Multi-Cavity Hot Runner Molds: For high-volume parts like syringes, we design 32-48 cavity molds to maximize output.
  • Corrosion-Resistant Steels: We use premium steels that withstand aggressive medical-grade plastics and sterilization cycles.

Material and Process Considerations

Medical molds must handle materials that meet biocompatibility and sterilization requirements. We work with a range of medical-grade polymers, each selected based on the application's mechanical, chemical, and regulatory needs.

  • PP (Polypropylene): Lightweight, chemical-resistant, suitable for syringes and test tubes.
  • PC (Polycarbonate): High transparency and impact strength, ideal for connectors and viewing windows.
  • COP/COC: Excellent clarity and low protein adsorption for pre-filled syringes.
  • PET: Good barrier properties for test tubes requiring low-temperature storage.

We also support TPE overmolding for soft-touch or sealing features, and we design molds to accommodate both EO and radiation sterilization without compromising part integrity.

Quality Assurance and Validation

Quality is built into every mold we produce. We follow a three-level inspection system—first article, in-process, and final—using 2D and 3D coordinate measuring machines. For medical molds, we provide full-dimensional inspection reports and mold trial validation to ensure your parts meet specifications.

Our molds are designed for long service life and stable production, reducing downtime and total cost of ownership. We also offer maintenance and refurbishment services to extend mold life.

Integration with Injection Molding

As an integrated supplier, we can take your project from mold design to finished parts. Our injection molding workshop is equipped with robotic pick-and-place units and centralized material feeding, enabling efficient high-volume production. This one-stop approach simplifies your supply chain and ensures consistent quality.

We support both small-batch pilot runs and large-scale production, with capacity to handle orders of varying sizes. Our team works closely with you to optimize cycle times and yield.

Information We Use to Configure Your Solution

To prepare an accurate quotation and mold design, we need the following from you:

  • 2D/3D drawings or physical samples of the part
  • Material specification (or we can recommend based on application)
  • Annual volume and expected cycle time
  • Required tolerances and surface finish
  • Sterilization method (EO, radiation, autoclave)
  • Regulatory standards you must meet (e.g., ISO 13485, FDA)

With this information, we provide a DFM analysis, mold design proposal, and firm quotation. We also offer free consultation on material selection and mold design optimization.

FAQs

What is the typical lead time for a medical mold?

Lead time depends on mold complexity and cavity count. For a standard multi-cavity mold, we typically deliver in 4-8 weeks after design approval. We provide a detailed schedule with your quotation.

Can you produce molds for both high-volume and low-volume parts?

Yes. We design molds with appropriate cavity counts—from single-cavity for low volume to 48-cavity for high-volume disposables. We also offer family molds for multiple parts.

Do you provide mold trial and validation reports?

Absolutely. We conduct mold trials and provide full-dimensional inspection reports, including CMM data, to confirm part conformity before mass production.

What materials do you recommend for medical syringes?

For syringes, we commonly use PP for disposable types, and COP/COC for pre-filled syringes requiring low drug adsorption and high clarity. We help you select the best material based on your application.

Can you handle post-molding operations like printing or assembly?

Yes, we offer post-processing services including pad printing, laser marking, assembly, and packaging. This allows you to receive finished, ready-to-use components.
