The Importance of Material Testing
Why should you test materials? What’s the purpose? Simply put, hiring an independent materials testing consultant is beneficial to a company for many reasons — some of which include meeting regulatory requirements, selecting the right materials and treatments for an application, analyzing product design and verifying a production process.
If a single component made of defective material goes into production, then the entire product may be compromised.
A seemingly miniscule deflection of just a few thousandths of an inch can produce showstopping scrap parts in a grinding machine. Likewise, manufactured fasteners and parts can play a pivotal role in maintaining the safety of planes, bridges, cars, nuclear reactors, military equipment and medical devices. In the medical field, for example, one inferior material used in a medical implant can spell life or death for thousands of patients.
Clearly, materials testing is essential. Yet it’s often one of the last steps in the manufacturing process.
Regardless of your industry, material testing and analysis is vital to understanding the integrity and performance of a material, ensuring the safety and satisfaction of all parties involved in the design and production of a plastic part or product.
At Plastic Expert Group, we provide comprehensive materials testing consulting services to a wide range of industries — from aerospace, manufacturing and medical companies to the energy and transportation sectors. We use state-of-the-art scientific research and the latest computer imaging equipment to accurately predict component lifespan based on its proposed application and prevent product failures.

What is Material Testing?
Materials testing is a widely accepted technique for analyzing the physical and mechanical properties of raw materials and components made from rubber, metals, plastics and other substances. Companies and manufacturers frequently utilize this information to evaluate the capability of a certain material for its proposed application. Material testing professionals like Plastic Expert Group conduct extensive scientific research and use advanced computer modeling to predict how a material will perform over its projected lifespan. We use accelerated laboratory testing to estimate a product’s useful service life.
Materials testing also plays a critical role when conducting a forensic failure analysis to determine the root cause of defective products and inadequate materials. These test results can play an important part in product liability litigation and depositions.
A wide range of tests can fall under the umbrella of material testing. Common types of material testing include:
Coefficient of friction
Creep and stress relaxation
Fatigue (load-controlled smooth specimen tests, strain-controlled smooth specimen tests, fatigue crack growth testing)
Hardness (scratch, indentation, rebound)
Impact (Izod, Charpy)
Tensile (Young’s modulus, elongation to failure, tensile stress, yield stress)
Toughness (fracture toughness: linear-elastic, K–R curve, elastic plastic)
Hiring a materials testing consultant from an independent and industry-leading laboratory like Plastic Expert Group ensures that you receive unbiased and thorough test results.
Materials testing is all about putting quality and performance at the forefront. Understanding a material’s properties can help you better predict the manufacturing outcome and detect costly variations before they become a major hit on your bottom line.
