Custom Injection Molding for Medical Devices

As a manufacturing process that allows for high precision, extremely tight tolerances, and a wide selection of materials, custom plastic injection molding is particularly suitable for applications in the medical field. The flexibility of the process also allows for fast prototyping and mass production, meeting the industry’s demand for both cost-effective and innovative solutions. In today’s article, we’ll go over the most important healthcare applications. Read on!

What is medical injection molding?

By closely following regulatory standards and using biocompatible materials, manufacturers can guarantee the safety and efficacy of different medical devices, from diagnostic equipment to surgical instruments:

Diagnostic equipment

Accurate diagnosis is of paramount importance in medical treatment, and it’s necessary for the components of the diagnostic equipment to meet this requirement. Blood analyzers, imaging equipment, and test kits, are only some of the components that require high tolerances and complex geometries to deliver accurate and reliable diagnostic results. Thanks to the consistency that injection molding provides, every part meets the stringent specifications and allows for precise functioning of these devices. 

Surgical instruments

Custom injection molding can produce highly reliable ergonomic grips, handles, and housings tailored to the needs of surgeons. These components are designed to withstand continuous sterilization processes and allow for better control and comfort during procedures. For instance, the process can yield durable laparoscopic instrument grips and scalper handles that meet the rigorous surgical standards. 

Implantable devices

Devices such as catheters, pacemakers, and orthopedic devices require materials that are biocompatible and capable of maintaining high performance over long periods of time. Thanks to advanced polymers that are both durable and biocompatible, custom molding can meet these requirements, making sure that these devices fit perfectly and function reliably within the human body. 

Drug delivery systems

Drug delivery systems include devices such as syringes, inhalers, and infusion pumps. They must deliver medication safely and accurately. Injection molding plays an essential role in their development, delivering components like intricate pump mechanisms or precision nozzles for inhalers with high accuracy and reliability, allowing for a correct and consistent dosage administration. This precision is critical for maintaining treatment efficacy and the safety of patients. 

Laboratory equipment

Laboratory consumables such as centrifuge tubes, microplates, and pipette tips are important for both reliable diagnostic and experiments. The injection process allows for the mass production of these components while maintaining high quality and consistency. This is particularly important for laboratory settings which require accuracy and reproducibility. In addition, high-quality materials ensure that the components don’t interfere with the substance they come in contact with, preserving the integrity of the obtained results. 

Prosthetics and orthotics

As prosthetic and orthotic devices have to be custom-fitted to the patient, injection molding is an ideal solution, providing both comfortable and durable components. It has the capacity to yield parts that are both lightweight, strong, and capable of withstanding daily wear and tear. In addition, biocompatible and skin friendly materials provide additional comfort and safety.
