L.E. Jones’ precise, efficient foundry operations are second to none!
Our proven foundry casting process raises the quality of our precision valve seat inserts.
Because our resin-bonded shell mold process is a near-net-shape process, only minimal machining is needed. In fact, some of our valve seats insert surfaces can be used as cast—without further machining. That means significant cost savings for our customers.
Our fully automated molding process ensures maximum capacity and efficiency. Foundry sand is tightly controlled and we use only the amount needed to create the molds, recovering, and reusing excess. This means safer, faster, and less wasteful mold production with controlled material costs.
Before the first mold is filled, we conduct spectrochemical tests to assure proper metal composition. Our dual spectrometers and furnaces allow us to cast up to 6,000 valve seat inserts every 45 minutes, meeting the volume needs of the largest customers around the world.
After the furnace, the cooled and cleaned castings are sent through our in-plant heat-treat facility to harden and temper the new inserts.
Through our entire foundry casting process, quality and safety are paramount. From precise casting to extensive testing, to investments in safety systems and training, the professionals at L.E. Jones maintain the highest quality with the safest possible working environment.
