Tag Key words : Pump Ceramic Piston / Ceramic Sleeve Piston
What is the use potential of high performance ceramics for current and future requirements in engine manufacturing? The Fraunhofer-Institutes LBF and IWM are analysing this in close collaboration with industry partners from the motor and ceramics industry. The starting point of the ongoing investigations in this area is the Pump Ceramic Piston / Ceramic Sleeve Piston used in diesel engines, because great development and sales potential are expected for this concept.
Mingrui extensive range of Pump Ceramic Piston / Ceramic Sleeve Piston enables us to offer a solution for every application. Sizes, compositions and materials can be varied based on customer specific requirements. Our most widely used Alumina tubing is available in a broad range of sizes and multi-bore configurations. Common applications include furnace and thermo-couple tubes.
Pump Ceramic Piston / Ceramic Sleeve Pistoncan be further machined into standoffs, washers and step bushings, which at lower quantities may be more cost effective than pressing processes, where costly tooling charges are typically required.
We offerPump Ceramic Piston / Ceramic Sleeve Pistonin different range from .020” to 8.250” (0.30mm – 500mm).
