医疗的 injection molding (MIM) is a versatile process that forces medical-grade plastics into a mold to create the desired shape and function. Medical plastic injection molding is used in the creation of prototypes, as well as market-ready medical devices. The FDA requires that only medical-grade plastics can be used in medical implants and devices, but there are several other key restrictions:Parts and devices must be durableParts and devices must be reliableParts and devices must offer increased versatilityPrototypes, parts, and devices must meet all FDA regulations.To the final point, the extent of FDA regulations is well beyond the scope of this post, but you may\u00a0click\u00a0here\u00a0to browse the hundreds of public guidance documents for medical devices\u2014including medical plastics\u2014made available by the FDA.End applications for medical injection molding include:Dental instrumentsProsthesesNeedlesSurgical instruments and bladesTubesMedical equipment componentsMedical device housing Why Injection Molding Medical Plastics Might Be the Best OptionInjection molding has many benefits to both manufacturer and patient, including:Cost-effectiveness. Once the molds are set, medical injection molding becomes a very economical process.Improved functionality. May be used with plastics of a wide variety of physical properties to ensure all specific functions are unhindered.Sterilization compatibility. Medical plastics are available with resistances to common medical cleaning solutions, antimicrobial properties, compatibility with autoclaving, and more.\u00a0Versatility. Capabilities for complex geometries ensure accurate parts that improve patient comfort.Safety. MIM also offers improvements for artificial limbs and other attachments by reducing the risk of infection and increasing patient safety. According to this study from\u00a0Clinical Orthopaedics and Related Research, available from the\u00a0National Institutes of Health, patients with metal-to-metal knee prostheses were 20 times more likely to incur a post-operative infection than patients receiving a metal-to-plastic knee prosthesis.All told, medical devices made from plastic injection molding contribute greatly to positive outcomes.\u00a0 Material Properties of Injection Molded Medical DevicesMIM is a highly adaptable means of production for a wide variety of medical purposes. The intended properties of the device will greatly inform the material selection process. Common medical plastics include:Polycarbonate. Polycarbonate is transparent and tough, making it a candidate of choice for medical tubing. Its high heat resistance classifies it as a thermoplastic. It also has low moisture absorption and is stronger than acrylic.PEEK. This medical-grade plastic is highly resistant to chemicals, cracking, and fatigue and its high temperature tolerance means it can be sterilized via autoclave. The FDA has also approved PEEK for contact with food due to its chemically inert behavior.Ultem. Used for a variety of medical devices for its flame-retardant properties, high strength-to-weight ratio, and low toxicity. Ultem is strong enough to resist environmental stress and cracking and its dimensional stability, high impact strength, and stiffness make it an excellent choice for many medical applications.

We rely on MIM for the following reasons:It offers a versatile method for mass productionIt allows for the production of prototypes at nearly any scaleInjection molding affords detailed features and complex geometriesInjection molding easily create physical prototypes for newly designed equipment in order to facilitate necessary testing and monitoringPlastic injection molding allows for great detail within the castValencia Plastics uses injection molding as a very cost-effective way to produce high-grade plastic devices. The use of extreme-pressure mold injection vastly reduces the amount of time required for production. This allows rapid turnaround at high volumes, as well as reduced labor costs compared to other production methods.We offer start-to-finish manufacturing services, including:Assistance with new product designEngineer services using CAD softwareComplete in-house mold shop utilizing CAM softwareAffordable short production\/prototype runsFull-scale production runs 24\/7Product assembly & fulfillment with custom packagingWe offer competitive pricing and use only state-of-the-art equipment and methods.
