The Advantages of Medical Device Injection Molding
Plastic Injection molding to manufacture medical parts, devices and components has served the medical contractors as one of the easiest and officious methods to achieve the quality and specifications they require in an efficient and economical way. Medical device plastic injection molding finds the following application in the medical industry:
Implantable Components
Beakers, Test Tubes, and other containers
Housing and casings of laboratory and medical equipment
Surgical Equipment
Surgical components
Drug delivery equipment and components
Orthopedics
Medical devices plastic injection is used in only a small number of ways. However, it can be used in almost any area of the medical industry where there's a need for long-lasting, sterilization-friendly parts in bulk quantity manufactured with excellent accuracy.
Medical Equipment
A wide range of medical equipment is manufactured through the Plastic injection molding process because it offers a variety of advantages, such as:
Cost-efficiency –
Plastic Injection Molding is one of the most cost-efficient manufacturing processes due to its economical nature, especially in bulk production. It is undoubtedly the most cost-effective choice when medical components, parts, or devices are needed in high volumes.
Impeccable Accuracy –
The production of medical devices requires a manufacturing process with minimal variations where microns or millimeters can prove to be a significant difference the can impact the proper functioning of a component. Plastic Injection Molding facilities that are proficient and equipped with the necessary skill set can produce components and devices in build with great accuracy and minimal part-to-part variance.
Materials Selection –
Plastic Injection Molding provides a wide range of material options for almost any manufacturing process. Although not all plastic materials can be utilized for the production of medical-grade components, there is a significant number of materials that can be meet the specification requirements for such components.
Durability –
Many plastic materials offer a great range of durability and strength. They are resistant to any sort of extreme weather or environmental conditions. These materials have a great level of endurance as they can absorb a significant amount of pressure applied in the form of vibration or blunt force without showing any signs of cracking or breaking. Moreover, some injection molding plastics are even heat resistant, so they can be easily sterilized again and again.
Contaminant Resistance –
The plastic materials that are utilized in the process of medical device injection are processed through a special design process to develop contaminant resistance. These materials are also easy to sterilize. Furthermore, the injection molding process itself works according to the guidelines and requirements of the FDA.
Material Properties –
The materials that are selected for the manufacturing of medical devices and components must have the following certain physical properties in order to be successful for these applications:
Ability to be sterilized
Whether a component is used as a part of a medical device that has a direct interaction with the human body or in building equipment housing, it should have a strong ability to be repeatedly sterilized and contaminant-resistant.
Suitable to be used in extreme environment
The medical components that are used in Bio-implants should be suitable to work in the extreme environment of the human body. They should be long-lasting, durable, and show a great level of endurance on exposure to heat, liquid, corrosives, vibration, and other pressure-based movements. Luckily, most of the plastic materials that are used in injection molding have these properties.
Durability –
The plastic materials that are easy to break can't be used in the medical industry because they are exposed to an environment where they're handled inconveniently. Always make sure that the material you have to choose is durable and breakage-resistant before applying it in the medical field.

Material Selection for Medical Device Injection Molding
As you have the basic knowledge about the must-have properties of the plastic materials to be used in the medical industry, it's time to introduce you to some specific plastic materials that are suitable to be applied in the production of medical devices and components:
Silicone –
Silicone is a preferred plastic material for the production of components and parts where flexibility is a key requirement. It is not only highly durable and biocompatible but also economical when used for bulk productions.
Polycarbonate –
Polycarbonate is a plastic material with high strength and vibration resistance. It's a material of choice for those production processes where visibility is the key requirement because of its completely transparent nature. Polycarbonate also shows great resistance against heat and UV light.
Polyethylene –
Polyethylene is a plastic material with a high molecular weight suitable to be used on the surfaces of prosthetics and wearable devices because of its good appearance, smooth surface, and high durability.
Polypropylene –
The Medical components that are repeatedly sterilized by using autoclave are preferably manufactured by using Polypropylene because of their high heat and radiation resistance.
