Material Matters: Choosing the Right Metals and Plastics for CNC Medical Components

Material Matters: Choosing the Right Metals and Plastics for CNC Medical Components

Proper material selection is the foundation of optimal product performance and longevity. Through informed material selection, manufacturers and equipment developers stand to maximize product value while minimizing costs and other issues that can arise if the incorrect material is used. 

So, how can you prepare your production runs for success from the start? Within each subcategory of medical equipment manufacturing, there is a wide variety of material options, and determining which options are best for your production needs is a complex process that requires careful consideration of material properties, costs, production methods, and other key factors that will impact your bottom line.

Our CNC machine shop is here to demystify this important topic. Following this helpful material overview and comparison, you will be prepared to make better material decisions, avoid production hurdles, and ensure superior part integrity.

Metals vs. Plastics: Key Material Considerations

Metals provide high strength, durability, and resistance to wear and tear. For demanding medical applications, such as surgical instruments and load-bearing devices that require material stability under stress, metals like stainless steel, cobalt-chromium alloys, and titanium provide a dependable foundation. For other specialty applications that require lightweight and low-cost materials, practical options like aluminum are easy to machine and can be used in a range of applications, such as diagnostic devices and surgical tools. 

Alternatively, plastics offer versatility, affordability, and ease of manufacturing, making them suitable for various applications where weight reduction or product transparency is beneficial. From biocompatible polymers that are safe to use in long-term implants to single-use patient accessories, plastics are an invaluable addition to many medical product lines. 

Metals generally have higher upfront production costs and longer production timelines but require less frequent replacement. This durability often translates into greater reliability and performance in demanding applications, which can be a crucial consideration for operational efficiency and long-term product quality.

Conversely, plastics are often cheaper and faster to produce, although the material lifecycle may be shorter. Plastic polymers may be the most cost-effective and viable solution for medical equipment applications requiring high-volume and/or complex shapes requiring advanced CNC milling processes.
