How Protoshop Excels

Protoshop sets itself apart from other prototype injection molding fab shops through a meticulous approach to prototype medical injection molding, emphasizing quality, precision, and flexibility at every stage. Specialized capabilities such as overmolding, insert molding, and expert machining makes Protoshop an ideal choice for medical parts requiring multiple materials or complex geometries.

Our extensive experience in diverse medical product applications, from surgical tools to IVD devices, allows Protoshop to tailor better molding solutions that avoid the pitfalls of less experienced prototype molders.  We collaborate with the customer to find the fastest, least expensive way to create injection molded parts geared toward understanding critical design features and pursuing multiple design paths. 

Protoshop’s Experience in Building Medical Components

At Protoshop, our experience spans an extensive range of medical projects, showcasing our proficiency in managing complex design requirements and production challenges. We emphasize the importance of integrating material selection early in the design process, allowing for accurate mold flow analysis and ensuring that the molded parts will meet engineering specifications

Medical Products Made with Injection Molding

Injection molding prototypes during design and development activities enable the efficient, high-volume production of critical plastic components for advanced medical products. Some examples include:

Microfluidic chip prototype

Device and Instrument Housings:

The external plastic casings encapsulating delicate internal electronics require precision dimensional tolerances that are only achievable through injection molding. Prototype molds yield higher quantities of prototypes at an affordable price and can be used to tweak the fit of all components before committing to production molds. 

In Vitro Diagnostic (IVD) Devices:

Diagnostic devices must be molded with inert materials to prevent the plastic from leaching into the assays. Development of these devices necessitates injection molding parts during testing and clinical trials to verify repeatability of assay results before high-volume production molds are produced.

Drug Delivery Systems:

From EpiPens to insulin pumps, injection molded plastic parts comprise the containment and delivery mechanisms, allowing controlled medication dosing. These critical features must be tested using production-equivalent parts and are prime candidates for prototype molding.

Diagnostic Equipment:

Test devices and lab automation tools depend on the tight tolerances and reliable reproducibility offered by injection molded plastic components. Prototype parts produced through injection molding ensure the systems function as intended before the products hit the market. 

Surgical Tools:

Scissors, clamps, forceps, and other instruments leverage injection molding to enable integrated features and ergonomic designs, boosting functionality. Production-equivalent plastic parts must be manufactured in clinical trials to fulfill product validation requirements. Prototype tooling can be used as production tools are being built.

With the capabilities to create tiny, complex, or multi-material components, injection-molded plastics are intrinsic to most cutting-edge medical product development. Our expertise in prototyping these intricate parts powers quicker innovation for clients worldwide.

Medical Injection Molding Case Study – In Vitro Diagnostic (IVD) Cartridge

In a collaborative effort to innovate In Vitro Diagnostic (IVD) cartridge design, our customer aimed to replace conventional assembly methods with a novel snap-together valving feature to control fluid flow efficiently. Our team engaged in developing and molding a prototype to ensure the precision and reliability of the valve assembly. After initial prototypes exhibited variability, we quickly adapted the mold design, achieving a successful snap-fit valve assembly with minimal cost on the second iteration.

Protoshop’s rapid prototyping capabilities proved critical in de-risking the innovative features of the product, allowing the integration of specific material properties and functional requirements essential for the IVD cartridge.

Having worked with Dylann and Jimmy prior to Protoshop, I knew the immense level of expertise they have for this business and it proved to carry through. They are honest straight shooters that will help guide you and find the best solution for your molds. We needed a mild that could be versatile and allow us to easily change out one side of the design. Dylann helped us come up with an approach that will allow us to continuously iteration the design without having to make a whole new mold every time.

Great experience with Protoshop. Dylann is extremely responsive and great to work with. Very fast turn-around. Worked with us on our order to get what we needed. I was able to drop ship 3d printed parts from another vendor to Protoshop to have them match-fit and incorporated into our tooling. I will be back again.

Dylann at Protoshop is excellent to work with: highly responsive and proactive. This is possibly the fastest, high-quality work I have ever witnessed. 1 week...from payment (start) to delivery (after CTQ measurements at Protoshop), we had 100 test samples of a component we intend to use in high volume manufacturing. Thank you for the tremendous work! I would highly recommend Protoshop, and will plan to use Protoshop services in the future.
