Injection moulding is a manufacturing process that has been around for centuries for creating plastic products, but it has only recently been adapted for use in the medical industry. This Injection moulding is widely used in the medical industry due to its ability to create complex 3D shapes with high precision.
Medical injection moulds have many applications starting from creating medical equipment to making medical implants. So in this article, we will take a closer look into the medical injection moulding method and how it becomes the next big thing in the future.
The process involved in medical injection moulding
Injection moulding is a process that involves injecting molten material into a mould to create the desired shape. By using pressure to combine plastic, metal, and other materials, engineers are able to make complex medical products.
Steps involved in the process:
Feeding and heating the thermoplastic material
Pre-injection process – Closing the cavity and the moving core
Injecting plastic at high speed and pressure
Formation of the required part – Cooling the mould
Perfecting the formed part – removing unwanted residues.
This process is often used for creating small, intricate parts and customized medical devices from thermoplastic materials that would be otherwise impossible to create with old manufacturing methods. Injection moulding is also very versatile, as it can be used with a wide variety of materials.
Materials used to make the parts
Mostly any type of thermoplastic materials can be used to create the parts and most medical injection moulds are made out of ABS (acrylonitrile butadiene), they can be customized to suit specific needs.
For example, if it needs to withstand harsh chemicals, silicone rubber is usually used instead of plastic. This is ideal for making medical containers or cups as it prevents contamination from harmful substances like hot chemical liquids. Engineers have also found ways to make medical injection moulds out of metal, which makes ideal for making medical implants or creating orthopedic devices for treating joint disorders among other uses.
The efficiency of Injection moulding
One of the biggest advantages of using medical injection moulds is its efficient way of producing the components. Injection moulds are much more durable than other methods of manufacturing.
It is also very easy to control which makes it possible to produce consistent results. This has led to greater product quality and customer satisfaction with every product created using an injection mould. Additionally, the material used to create the injection mold makes the solution strong and effective.
Growth of Injection moulding technology
The medical injection moulding market is expected to grow at a CAGR of 5.7% from 2022 to 2030 (Reference Grandview research). Some of the challenges faced by the market are the high cost of medical injection moulding machines and the lack of skilled labor.
The medical industry is always looking for new and improved ways to create medical devices, and injection moulding is one of the most promising technologies. Injection moulding has the ability to bring change in the medical industry, and it is already having a major impact on the way medical devices are manufactured.
