We welcome tough manufacturing challenges. Our skilled, efficient foundry operation’s resin-bonded shell mold process results in cost effective near-net shape valve seats. Then our precision machining, exacting tolerance testing, and packaging take place within dedicated manufacturing cells to maximize efficiency and ensure the highest degree of quality.
We invest in people and technologies that allow us to take advantage of advanced engineering. We’re proud to employ innovative metallurgists and engineers; our team currently holds a combined twelve U.S. & Chinese patents as well as numerous patents in other jurisdictions around the world. State-of the-art metallurgy, metrology, spectochemical analysis, real world simulation—and exceptional design and manufacturing capabilities—help us produce the world’s finest valve seat inserts for many of the world's best engine and truck makers.
Grounded in a global understanding...
Around the world, engine and truck makers face a fierce reality of ever-changing regulatory and environmental requirements coupled with intensified end-customer demands driven by the need for greater performance and lower cost. The volatile economic environment of the past several years, combined with erratic swings in order volumes, have made it challenging to predict future volumes and ideal inventories.
The best engine and truck makers face these challenges with innovative designs and by fostering true partnerships with top-flight suppliers. L.E. Jones is just such a partner to many of the world’s greatest engine and truck makers. Why? Because L.E. Jones is able to quickly adapt in assisting with engine design parameters and testing, materials technology, production capability, capacity management (up and down) and assisted just in time inventory management and shipping. L.E. Jones is a vital partner in our customers’ success—minimizing costs and providing enhanced service well beyond supplying parts.
We are honored by our customer relationships. We know the issues they face and consider it our job to help them thrive while overcoming simultaneous challenges in multiple markets.
