Fatigue testing contract services | JTL

Fatigue testing contract services | JTL

We will sincerely respond to the realization of all fatigue tests, from various materials such as resin and rubber to parts for automobiles and aerospace.

In recent years, the demands for product safety and reliability have become increasingly sophisticated. In particular, "durability" is recognized as a very important evaluation criterion related to product failure, and it is assessed at various stages from the research and development phase to the completion phase of the product. To meet these demands, our company offers contracted fatigue testing services. We not only evaluate the materials themselves but also accommodate special component shapes and product designs, including the creation of dedicated jigs and processing for the products. Please feel free to consult with us.

Contracted services for degradation analysis | JTL

Contracted services for degradation analysis | JTL

We will evaluate the degree of degradation of polymer materials using FT-IR.

Unlike metal materials, polymer materials such as plastics are less prone to corrosion like rust; however, they can deteriorate due to heat and ultraviolet light. Yellowing, commonly seen in plastics, is one such example. In degradation analysis services, FT-IR is used to evaluate the degree of deterioration in such samples. The results can be utilized as a material for identifying the cause of defects in products that show signs of damage.
