Types of injection molding used in medical devices
1. Conventional injection molding
This injection molding process is widely used to manufacture various medical devices. It involves melting plastic pellets or other materials and injecting them into a mold cavity under high pressure. This method is very effective in producing medical parts with high precision and complex geometry. Examples of medical parts produced include syringes, sample cups, and IV components.

2. Thin-wall injection molding
Thin-wall injection molding is a specialized process for manufacturing parts with extremely thin walls, typically less than 1 mm thick. The thinness of the wall is important because the size of the part limits the wall thickness. This process is commonly used in the medical industry, where lightweight, high-strength components are essential. Thin-wall injection molding can significantly reduce costs, making it preferred for high-volume production. The main applications for this process are small housings for medical devices.

3. Overmolding
Overmolding is an advanced technique that involves europe datasetmolding one or two components onto a pre-existing structure, resulting in a strong and durable grip. It eliminates the need for assembly after molding. Overmolding can create handles for surgical instruments and can also improve medical products without metal parts. For example, silicones or thermoplastic elastomers (TPEs) are molded onto thermoplastic substrates.

4. Insert the casting
Insert molding allows for the addition of durable or structural elements to plastic parts, although for medical components such as IV connectors, purely plastic designs are preferred for biocompatibility reasons. Plastic can be injected around metal inserts, magnets, or electrical components

5. Liquid silicone injection molding
Liquid silicone rubber (LSR) injection molding produces flexible, biocompatible parts that are resistant to extreme temperatures, chemicals, and aging. The process uses two-part liquid silicone rubber that is injected into a mold and cured to end-use properties.

LSR is ideal for medical devices that require flexibility and biocompatibility, making it suitable for items such as catheters and seals that often come into contact with skin or bodily fluids.

Another advantage is that silicone is biologically inert, which allows for safe implantation in the body since it does not react with biological tissues.

6. Two-stage casting (two-stage casting)
Two-stage molding is a designated technique that involves molding and overmolding the medical device or component in a single operation. It begins by forming a basic shape, then additional material fills the remaining space to add a different texture or color. This process allows for the creation of complex parts and the combination of different materials to improve functionality and appearance in a single production step. For high-volume programs, this process can provide cost savings.
