Overview of our Engine Valve Remanufacturing Process |
Just as engine rebuilders may work with core heads, blocks or water pumps, we begin with valve core that is usually provided to us by our customers in a type of exchange program. You, as a head or engine rebuilder, simply strip down the heads and toss the worn valves into shipping crates rather than into a scrap bin. There's no need for you to do any cleaning, inspecting, or sorting of the valves. Just remove them and drop them in the crate. Since you're stripping a particular engine, you'll be needing replacement valves for that same engine. That's why we inventory our +8 automotive valves for same day order fill, or special order through an exchange. Of course, you are not limited to valves for which you have core, since we also purchase core from other sources to ensure that we have an adequate supply on hand.All incoming core is sorted, pre-cleaned and oiled before going into a holding area. Once we receive your valve order, one of our Initial Inspectors will pull the needed number of engine valves from the holding area, complete their detailed inspection of each engine valve, and assign a lot number to those engine valves that pass inspection. A computer generated Production Lot Sheet is then printed which contains the list of operations, machine set-up specifications, and other details that are specifically for that part number. Our Tracking Program, with it's database, enables us to record and monitor every operation of the remanufacturing process - from initial inspection through final inspection and packaging.Each engine valve may be subjected to as many as 14 different manufacturing operations. Before certain operations are allowed to begin, two different operators must agree that the machine set-up is within the specifications called for on the Production Lot Sheet. This ensures that your parts will be processed as quickly as possible and will not need to be held for reworking. To ensure that we are meeting or exceeding your expectations (with respect to providing you a quality product), we use some of the best gauging and measurement equipment including digital and laser micrometers, optical comparator, eddy current detector, profilometers, dial indicators and digital hardness testers.Several key processes (such as hard chrome plating of the engine valve stems and grinding of the faces) are computer controlled. By selecting the proper part number and completing a few prompts, certain operations are allowed to be started, run, adjusted, monitored and stopped automatically by computers. This ensures that your parts are sized accurately, consistently, and efficiently. Automating operations such as these enables us to easily customize engine valves to your exact specifications.You can review our Typical Tolerances For Valve Remanufacturing to see for yourself how much control you can have in the remanufacturing of your valves. Upon your request for a quote for a new part (or for customizing an existing part to your specifications), our quality department will work with you to establish the specifications and tolerances of your valves. We will then send you a completed Product Specification Request Form for your approval prior to the first production run. This form will specify all of the pertinent valve properties you require such as:
Of course, we'll assist you with this process and help with any properties that may be unfamiliar to you.For more specific information on our remanufacturing process, please click HERE. > |
