What are the types of injection moulded parts for medical devices?

Injection moulded parts of medical devices are an indispensable part of medical device manufacturing, with various types and different functions.

The following is a detailed answer to the three main types and characteristics of medical device injection parts:

(1) disposable injection molded parts of medical devices
This type of injection molding parts are usually used to manufacture some low-value consumables, such as syringes, infusion sets, catheters, etc. These moulded parts need to meet strict hygiene and safety standards to ensure that they do not cause any harm to patients during use. Therefore, in the production process, it is necessary to use high-quality medical grade plastic materials and ensure the accuracy and reliability of the product through the precise injection molding process.

(2) Injection molded parts of medical devices with complex structures
This type of injection molding is usually used to manufacture some high-precision medical devices, such as cardiac pacemakers, artificial joints, and so on. The structure of these injection moulded parts is complex and requires the use of advanced injection molding technology and equipment to manufacture. At the same time, in order to ensure the stability and safety of the product, it is also necessary to carry out strict inspection and testing of the injection parts.

(3) injection moulded parts for medical devices with special functions
For example, some injection moulded parts for surgical navigation need to be highly transparent and resistant to wear. Some injection moulded parts used for implants require good biocompatibility and corrosion resistance. These special function injection parts need to take into account more factors in the design and manufacturing process to ensure that they can meet the specific needs of use.

In terms of materials, medical device injection molding parts usually use medical grade plastic materials, such as polyethylene, polypropylene, polyvinyl chloride and so on. These materials have good biocompatibility, mechanical properties and processing properties, and can meet the various needs of medical device injection parts. At the same time, with the continuous development of science and technology, some new materials are also used in the manufacturing of medical device injection parts, such as biodegradable materials, composite materials and so on.

In general, there are a wide variety of injection parts for medical devices, and each type has its own unique characteristics and application scenarios. In the selection and use of these injection parts, it is necessary to make comprehensive consideration according to the specific needs and scenarios to ensure that they can meet the manufacturing and use requirements of medical devices.
