Medical Injection Molding

The process is capable of making FDA approved medical devices that are both durable and reliable. This type of molding can also be used to make prototypes to send and get the much-needed FDA approval. Medical injection molding can be performed in a clean room and the components can be sterilized without harm as well. Let's take a look at injection molding.​

Injection molding is a very common way to form plastic parts and components. Depending on the material, the parts can be very strict with their tolerances as well as easy to process. Injection molding is one of the most common types of forming plastics. It is used in a variety of industries and not just for medical injection molding. In fact, you probably have a wide variety of injection molded parts all around you and simply don't know it. Your basic pens, your keyboard, and even your phone have injection molded components in them. ​

Different materials for injection molding

The most common types of materials used in medical insert molding are thermoplastics. These are materials that can be heated up into a molten state and pushed through a barrel into a mold. These molds can simply be open and shut type designs, which are what you would expect for, say a simple product such as a cake mold. Or they can be very complex with moving side parts called slides. Of course, the simpler the mold the better for maintenance and longevity. However, complex parts will need these complex designs in order to produce the desired part.

However, there are other types of plastics called thermosets that also can be used for injection molding, but the process is far different. These materials are most likely not going to be used for medical molding as they cannot be recycled as easily as the thermoplastic materials.  Because of this, you don't see thermosets used as often as you do thermoplastics. A good example of a thermoset is your car tires. This is where they cannot be melted down and reshaped into something.

Sometimes the components need to be manufactured separately and then assembled. This is very common in many cases and this can be done by hand or robot.

Insert injection molding with Aberdeen Technologies

In the medical field, we often see metal combined with the plastic part. This is called insert molding and is a very common practice for injection molders to do. You see this all over the medical arena from needles to EKG hook up leads and more. 

Medical injection molding is a core technology of Aberdeen Technologies and represents a cutting edge solution to the manufacturing needs of healthcare companies who produce medical molded devices. As an insert molding manufacturer, we provide assistance to device manufacturers who approach us with new product concepts and ask us to mold parts for clinical trials and marketing evaluations.

Once these new devices are produced, we assist our customers in transitioning the project into the production phase. Quality and customer satisfaction are our primary goals, and Aberdeen can work with both high and low quantity requirements with over 700 square feet of cleanroom injection molding space.

Prime examples were molding non-communicating passageways through a plastic manifold, molding critical tolerance pacemaker components, and even molding around glass formations without breaking or cracking. Our advanced injection molding equipment makes even the most difficult projects possible.

We provide assistance throughout each stage of your program, from design recommendation through mold tooling fabrication, prototyping, first article approval, process validation, full scale production medical molding, and transfer of turnkey system to customer facilities if requested.

Aberdeen’s primary goal is total customer satisfaction for even your most challenging projects. Our company culture is one of honor, respect and service with the highest degree of competence and professionalism that you will find anywhere.

Typical applications for which we are called upon for assistance include:​

• Multi-Purpose Medical Needles

• Multi-Lumen Catheters

• Male/Female Luer Locks

• Trocar Handles

• Scalpels and Other Instruments

• Pacemaker Components

• Filters

• Patient Electrodes

• Fetal Monitoring Probes
