Diesel Engines Glow plug CP-73 for NISSAN ZD30

  A Comprehensive Analysis of the Production Process of Engine Glow plugs.   The performance of the engine Glow plug largely depends on its production process. From raw material selection to finished product assembly, every link needs to be strictly controlled in order to produce high-quality, reliable and durable preheating plugs.   1. The first step in the production of Glow plugs is the selection of raw materials. ●The core resistance coil usually adopts alloy materials with high resistivity, high temperature resistance and good oxidation resistance, such as nickel-chromium alloy. This material can generate heat stably when an electric current passes through and is not prone to aging or damage in a long-term high-temperature working environment. The metal casing is mostly made of stainless steel or special alloys.  ●They not only have good thermal conductivity but also can withstand the high temperature, high pressure and vibration environment inside the engine, protecting the…
