    • A spark plug and a method of manufacturing the same, where the spark plug has a metal shell, an insulator, a center electrode, a ground electrode, and a gasket located over a threaded portion of the shell and used to seal the spark plug against a cylinder head. Once the gasket is attached on the spark plug, it is shrunk to become a post-formed gasket with an inner diameter that prevents the post-formed gasket from slipping over a threaded portion of the metallic shell. This process may be carried out with a collet type machine that produces a post-formed gasket that is flat and has a substantially uniform thickness, which can improve the sealability of the gasket. This may be important when the spark plug is installed in a cylinder head made from a lost foam casting process or other process that creates a somewhat porous sealing surface.
    • 一种火花塞及其制造方法,其中火花塞具有金属壳,绝缘体,中心电极,接地电极和位于壳体的螺纹部分上方并用于密封火花塞的衬垫以抵抗 气缸盖。 一旦垫圈附接在火花塞上,它就会收缩成为一个内径的后成形垫片,该内径可防止后成型垫圈滑过金属外壳的螺纹部分。 该过程可以用夹套式机器进行,该机器产生平坦的并且具有基本上均匀的厚度的后成形垫圈,这可以提高垫圈的密封性。 当将火花塞安装在由失去泡沫铸造工艺或其它工艺制成的气缸盖中时,这可能是重要的,其产生稍微多孔的密封表面。
