Silicon Nitride Ceramic Riser Tube For Low Pressure Die Casting introduction

Silicon nitride is a man made compound synthesized  through several different chemical reaction methods.The material is light grey with polished to a very smooth reflective surface,giving parts with a striking appearance. It has the advantage with high performance for automotive engine wear parts, very high quality bodies and high reliability.

It is available today and can be used in many sever mechanical, thermal and wear applications such as valves and cam followers, proven effective and the ceramics feasible in engines and turbochargers.
