There Is No Substitute For Seeing Our Product In Action

Testing, Testing… When It Comes to Analysis and Understanding How Our Parts Perform: We Are Relentless!

Our in-house Plint Wear Testing and Bruker TriboLab instruments along with the testing procedures are established at LEJ to meet customer engineering design and application needs which have been widely accepted by engine manufacturers and the high alloy industry.  Plint wear test provides a method to physically simulate real-world conditions (e.g., elevated temperature and contact stress variables) and reveals tribology behavior of engineering components, hence, can substantially reduce the number of dyno and engine tests needed for new engine design and engine improvement effort.  The LEJ state-of-art metallographic lab with advanced SEM/EDS system and high-resolution OLM instruments further enables our researchers and engineers to correlate alloy composition, microstructure, and performance for engineering components and testing samples.

Our technological and analytical capabilities are enhanced with brand new metrology, physical property test, and sophisticated metallurgical laboratories where precision dimension and contour feature of engineering component, comprehensive composition, thermal expansion, radial crush strength, bulk/micro/superficial hardness, bending strength, corrosion resistance, induction response, temper response, bending strength, thermal exposure history mapping, dimensional stability of alloys/materials can be determined/defined.

L.E. Jones’ engineers rely on technology and experience to establish and test tolerances for all aspects of our valve seat insert products. We can also advise on the best gauging practices and tolerances for your particular situation.
