What do I mean by Injection Molding in the medical industry?
Medical Industry is one of the most important verticals for any country as it provides immense value to the healthcare industry. When it comes to manufacturing medical components, plastics play a huge role. Medical injection molding can be utilized to manufacture high-end, great-quality medical plastic products.
The medical injection molding process is fast, reliable, durable, and provides a lot of flexibility to try out many different things to make good quality products serving the medical industry.
Plastic medical devices produced using high-graded plastic material to achieve near-to-perfect results. The prime benefit of using plastic injection molding is to do interesting work and create products that can fulfill niche purposes.
The Pros of Medical Device Injection Molding –
Medical suppliers have often reviewed that medical injection molding is the most effective way to efficiently produce medical parts and components. The quality and specifications which can be achieved by medical molding are substantially more than any other manufacturing method. Here are some standard applications of medical device injection molding –
- Surgical equipment and components
- Drug delivery components
- Housing and casings for laboratory equipment.
- Test tubes and containers.
- Dental instruments
- Medical Knobs
Along with dozens of applications, medical injection molding gives medical supplies and manufacturers several other pros, which are crucial in the process. Below I have discussed those pros in detail.

#1 Cost-Reduction –
Even not including medical components, injection molding is the most cost-effective plastic manufacturing method. It will be more competent when medical components are required in bulk quantity. Injection molding easily by far the most cost-effective option out there.
#2 Material Selection –
Injection molding swags a huge material selection for molding compared to all other manufacturing processes. Medical grade requirements are usually narrow, decreasing the choices, but the number of material that meets our requirements is still awe-inspiring.
#3 Exceptional Accuracy –
As for medical devices, manufacturing accuracy is everything. A single micron can make a staggering difference in a component’s performance. Roping a company with enough capabilities to manufacture components in bulk quantities with perfection is extremely crucial. Similar quality production for every part produced is obviously a tough task but achievable.
#4 Durability –
There are many options for injection molding with plastic materials that are supreme in quality and durability. They can withstand harsh conditions like weather, vibration, heating, and force with negligible effects. Medical components should have these qualities to be the best at whatever they are being used for.
The Importance of Plastic injection molding in the Medical field –
For a long time now, the use of medical injection molding in medicine has increased steadily. Medical products manufacturing using injection molding have contributed immensely to the medical industry by reducing cost, saving lives, and whatnot. The risk of infection through infectious diseases has dropped significantly.
High-tech polymers have helped create world-class products in the medical field that have helped millions with a better quality of life: artificial limbs, mobile health products, and no infection devices.
Medical Injection Molding Materials –
For medical injection moldings, only materials with high molecular weight and heat resistant properties can be utilized. All the thermoplastics used in medical molding have their own advantages and disadvantages over the others. Let’s talk about some of the materials.
#1 PEEK (Polyether ether ketone) –
PEEK is a colorless and organic thermoplastic material belonging to polyaryletherketone family. It is a highly used medical-grade plastic resin with high resistance to chemicals, fatigue, and cracking. One major benefit of PEEK is that it can be sterilized by autoclave. It has an FDA approval for food rating.
#2 Polycarbonate –
Polycarbonate stands out among other thermoplastics because of its natural transparency. They can easily be shaped, and Thermo molded into various shapes, sizes, and structures. With a fair radiation resistance and an impressive heat resistance of 0.45 MPa: 140 °C … its adequate for manufacturing test tubes and chemical containers.
Other notable features include high tensile, flexural, and shear strength.
#3 Ultem –
Ultem is thermoplastic manufactured by SABIC and is quite similar to PEEK in terms of properties and applications. Ultem has good heat, stress, steam resistance, and excellent dimensional stability, and it is specially manufactured to be processed in an autoclave.
#4 Polyethylene –
Polyethylene is known for its high molecular weight, durability, and relative smoothness. High strength and cost-effectiveness make it perfect for manufacturing prosthetics and wearable devices. The only drawback you might find is that it can e sterilized in the autoclave.
#5 FEP (Fluorinated ethylene propylene) –
Just like Polycarbonate, FEP is also a transparent material with low friction and chemical torpidity properties. Resistance to sunlight is also one of the properties rarely found in any other thermoplastic material makes it perfect to manufacture products that are subject to weathering.

Considerations for Selecting Medical Injection Molding Plastic Materials –
#1 FDA Requirments –
FDA is necessary for commercial manufacturing any usage of any medical device. Different products have different regulatory requirements. Medical devices used for tubing and containing have different regulatory legalities than those that have used implants.
Ensuring that your manufacturing partners have all the approvals and can order an audit for medical-grade approval.
#2 Strength –
The plastic material you choose should be strong enough to be utilized for manufacturing medical components. Medical grade plastic material should have enough strength to withstand resistance and should be adequate for the application.
#3 Sterilization –
Sterilization is the prime requirement for any medical component, regardless of its application. If the component or even the final product is contacting a human body in any way, the used material must be contaminant-resistant and able to be sterilized, so it doesn’t harm any human.
#4 Durability –
Crack and breakage resistance is a common norm in medical injection molding. Easily breakable materials are not made for the medical industry. Ensuring the resistance of the material for getting perfect results is very important in the medical field.
