How are moulded plastics used in the medical field?
The medical industry is critical and makes extensive use of moulded plastics. It provides equipment and tools to the healthcare sector all over the world in order to save lives and protect people’s health. As a result, high-quality materials are critical in this industry. Plastic injection moulding is a popular material for medical equipment and components. This is because they can be manufactured to extremely high quality standards. To ensure patient safety, anything manufactured for the medical sector must pass stringent compliance measures. As a result, the plastics used must meet the same stringent requirements.
Is there an increase in demand for medical plastic parts?
In recent years, there has been a significant increase in the demand for medical plastic parts. This is due in part to advances in medical care necessitating the use of new and more innovative plastic components. It is also due to people living longer lives and expecting a higher quality of life. As a result, they want improved access to high-quality, hygienic-moulded plastics in medical applications to help them live their lives to the fullest.
The recent COVID-19 pandemic has also increased global demand for personal protective equipment (PPE). This is made of moulded plastics and frequently requires a very precise shape and size. Plastic moulding processes, for example, can produce large quantities of closely fitting face shields, plastic screens, specialised signage, and hand sanitizer bottles. Because the packaging for these items has increased, so has the demand for this application.
Why is plastic injection moulding a viable option?
The medical injection moulding process is a dependable, quick process that produces high-quality, long-lasting products. As previously stated, any application requires medical-grade plastics, which are well suited to injection moulding processes.
In medicine, moulded plastics can be made into any shape. They are sanitary and strong, and they can be formed into extremely specific specifications for precise medical applications. Medical injection moulded plastics can be manufactured in any quantity required, from one-off items or prototypes to mass production.
Plastic injection moulding produces extremely accurate results. Many high-quality polymers are being used in world-class technical innovations. People rely on them as a result of their durability and versatility. This appears to be the case for the foreseeable future.
What medical devices are made of injection moulded plastic?
Medical grade components are typically made from plastics and polymers with a high molecular weight and heat resistance. Polymers of this type, for example, include:
- Polyetheretheretherketone (PEEK) has excellent chemical, fatigue, and crack resistance. It’s also resistant to thermal degradation and radiation.
- Polycarbonate is naturally transparent, which makes it suitable for a wide range of medical applications, including chemical containers. It is fire and UV radiation resistant.
- Polyethylene is extremely tough and smooth, making it an excellent material for prosthetics, plastic joints (hips and knees), and wearable devices.
- Another common medical plastic material is polystyrene. It can be used for packaging and cushioning fragile items, as well as insulation.
- Fluorinated ethylene propylene is transparent and has good sunlight resistance. This makes it an excellent choice for medical devices that are exposed to the elements and are more susceptible to weathering damage.
All of these medical plastics are strong and durable, and they can be sterilised to help prevent infection and keep the area clean and sanitary. They are also light, ergonomic, and simple to use.
What kinds of medical devices are made with injection moulded plastics?
Plastic injection moulding can be used to create a wide range of medical components, tools, equipment, and devices. The following items and equipment are included:
- Surgical instruments and supplies This includes pre-surgery equipment and supplies.
- Orthopaedics. In this field of medicine, injection-molded plastics are used in prosthetics, or artificial limbs. Prosthetics must be precisely fitted to avoid irritation or rubbing when worn.
- Dentistry. Dental instruments, orthodontic devices, and x-ray equipment components are all made from medical plastics.
- Drug administration. Plastic components are common in syringes and automated drug dispensing devices, such as those used for insulin or pain management.
- Laboratory apparatus. Non-glass test tubes, Petri dishes, beakers, and syringes are included. They can also be used in laboratory equipment and machinery as casings and housings.
- Mobile medical devices Crutches, wheelchairs, portable oxygen tanks, and slow-release drug dispensers are examples of such equipment.
The plastic injection moulding process can greatly benefit all of these. It can also benefit a number of sectors including housing and construction, electrical, waste management and many more.
