Material Selection

Supply Chain Solutions Seisa Medical

Material Selection is a critical and complex process within the medical device industry. The careful selection and composition of materials used in the manufacturing of medical devices directly impacts their performance, reliability, and overall effectiveness. This process is essential for ensuring the optimal operation of the devices and the accuracy of their results. By meticulously evaluating and choosing the appropriate materials, healthcare professionals can enhance the functionality and quality of medical devices, ultimately benefiting the entire healthcare system.

Material Selection for the Design and Manufacture of Medical Devices

Selecting suitable materials is crucial in developing medical devices, and expert guidance is essential. At  Seisa Medical, our specialized Material Selection service focuses on designing medical devices to ensure regulatory compliance and optimal functionality.

Depending on the specific product being developed, we utilize the following methods:

Injection molding

This process is ideal for creating advanced medical supplies. We use durable and moldable plastic materials like ABS, polycarbonate, and acetal, known for their strength, resistance, and moldability.

Metal processing technology

For specific devices, we employ metal processing techniques using materials like nitinol, chrome, cobalt, and stainless steel. These materials offer excellent strength, biocompatibility, and corrosion resistance.

Extrusion process

To meet diverse device requirements, we utilize materials such as PVC, VESTAMID, AESNO, NYLON, LDPE, MDPE, HDPE, FPVC, PEBAX, PP, POLYAMIDE, PUR, TPU, GRILAMID and URETHANE in the extrusion process. These materials are known for their durability and high chemical resistance.

Our team of modeling experts excels in optimizing plastic parts through specialized techniques, including micro-molding, over-molding, and shot molding. These techniques enhance the functionality and performance of plastic components in medical devices.

Typical Use of Material Selection in Medical Devices

The selection of appropriate materials is crucial for implantable medical devices, as they must be biocompatible, maintain their shape over time, and resist corrosion.

Commonly utilized materials in implantable devices include nitinol, stainless steel and tantalum. These materials possess the necessary properties to ensure long-term performance and compatibility with the human body.

Apart from implantable devices, material selection is critical in manufacturing molds and plastic prototypes. Materials such as polycarbonate, polyethylene, and silicone are frequently chosen due to their flexibility, precision, and durability. These materials contribute to the production of high-quality parts that can withstand the demands of medical device manufacturing.

By leveraging Seisa Medical’s expertise in material selection, manufacturers can ensure the successful development of high-quality medical devices. The desired functionality, longevity, and overall performance of medical devices can be achieved through meticulous consideration and choice of materials.
