A Brief Guide To Medical Injection Moulding

The industrial manufacturing process of injection moulding is one that is used often within the medical industry, as it offers a wide range of advantages and can be used for a number of different applications. For instance, high grade medical plastics are used in the injection moulding process to produce medical components, medical devices, facility and laboratory equipment, plus so much more. The main reason why injection moulding is favoured is because it can be done to very exact specifications, including those necessary for a medical product or device to meet required regulations. 

The advantages

The suppliers of medical products and devices have found cleanroom for medical injection moulding to be a highly effective way of getting the levels of quality and specifications needed, whilst also being super efficient and, best of all, cost effective. As a result, the process of injection moulding is used for a wide range of applications, including orthopedics; implantable components; drug delivery components and equipment; test tubes, beakers, and containers; surgical components and equipment; casings and housings for laboratory and medical equipment.

These things represent just a few of the ways in which injection moulding is used within the medical industry. The process can, in fact, be used to make any medical products or devices that need to be not only sterilization friendly but also durable, and to be manufactured in large volumes with a high level of accuracy. Production to tight tolerance levels is a critical factor in the manufacturing of medical grade products.

The materials

There are only a handful of materials that are suitable for the process of medical injection moulding. In the most part, it is plastics that are the best to use as they offer benefits over other materials, such as being highly flexible, being cheap to use, and can be used to manufacture products / devices at speed. Some of the best plastics to use include the following:

  • Polypropylene – where a component or part requires regular sterilization using autoclave, then this material is the perfect choice. This is because it is highly heat resistant, as well as being radiation resistant also. 
  • Polycarbonate – as far as plastics are concerned, this is one of the strongest out there and so can withstand lots of vibration and impact. Because it can be produced to be pretty much fully transparent, it is the ideal option to use on those medical products / devices where visibility is an important requirement. Additionally, the material is also resistant to both UV light and heat.
  • Polyethylene – possessing a large molecular weight, this material is well suited to make wearable medical devices, such as prosthetic limbs. It is highly durable whilst also being quite smooth to the touch. The only downside to this material is that it cannot be subject to sterilization with autoclave. 
  • Silicone – this material is highly flexible and so is ideal for use when making those parts or components where this is a requirement. In addition to this, it is also extremely durable and provides a cost effective solution for when large production runs are required.
