Many new materials, such as carbon fiber composites, nanomaterials and additive manufactured materials often assume properties and characteristics that are the result of how they interact during the manufacturing process. This can lead to a high variability in the known material making it difficult to ensure consistency when there is a disruption in the supply chain, the specified material is no longer available, or there has been a change in the specified material.
What You Need to Do When Your Material Changes
Ensure the change in the material does not offset any of the original materials’ characteristics.
In the interest of ensuring product safety and/or regulatory compliance, every manufacturer needs to establish that any minor changes to their material or process do not negatively affect the material’s properties. We perform materials comparison testing to evaluate the raw material and how it is manufactured, and we review data from the supplier to determine how it will react during your process. The new or substitute material you choose must compare to the original material in mechanical, physical, chemical and toxicological properties.
Our materials experts will:
- Help you minimize the risk of any negative event or material failure
- Identify and evaluate any known or suspected material changes
- Ensure that the material will not change your product quality or jeopardize safety
In some cases, we can perform simulation testing to determine the changes the material undergoes during the process. This often precludes the necessity of redoing the product testing with the substitute material and costs significantly less.
Who Needs Materials Comparison Services
Whether your product is subject to regulatory requirements such as pharmaceuticals or medical devices, or you are choosing aggregate for asphalt pavement or an alloy for an aircraft, you need materials comparison analyses when:
- Your materials supply chain is disrupted
- Your material is no longer available
- Your supplier has changed the material formula
- You have a new supplier
- You have more than one manufacturing location and need to ensure consistency across the board.
- You open a new manufacturing facility
- You change your manufacturing process
- You need to compare a new material to the characteristics of the original
