Ceramic Spark Plug Manufacturing Process

The present invention relates to a spark plug having a novel center discharge electrode and a manufacturing process thereof.

Ceramic spark plug manufacturing process.

It forces the spark to jump the gap which initiates combustion. Manufacturers implement quality control standards and practices throughout the process to ensure accuracy and safe manufacturing so that spark plugs can fulfil their function. Each major spark plug component is manufactured in a continuous line assembly process. Works with you on any product you need from prototype development to resolving any issue.

In the former type a. The process used to form ceramic materials is a heat treatment of very fine powders of the raw materials called sintering. Established in 1995 shengda ceramic employs 70 employees. Specifically designed to reduce quenching.

A process for preparing a spark plug insulator blank by dry pressing a powdered ceramic composition mainly comprising metal oxides comprising the steps of. The electrodes in a spark plug typically consist of high nickel alloys while the insulator is generally made of aluminum oxide ceramic and the shell is made of steel wire. Introducing suflicient powdered ceramic composition into a filling chamber to fill said chamber of a pressing tool comprising a stationary bottom ram having a pressing needle rigidly secured thereto and extending upwardly into said. Ngk spark plugs provide better ignitability and quicker starts.

The unprecedented level of ceramic performance we have achieved in surefire plus spark plugs enables a new generation of ignition systems that provide greater energy and. Ceramic materials ceramic materials cannot be formed by the manufacturing processes known from metallic or organic materials. Ngk is the world s largest oe supplier and manufacturer of spark plugs. Shengda ceramic is located in yixing china with an area of 4 000 square meters and fixed assets of over 1 million us dollars.

Known for durability and performance ngk manufactures oe spark plugs for inboard engines over 90 of outboard engines and almost 100 of personal water crafts. The energy to melt and cast ceramic raw materials would be far too costly. Manufacturers test incoming parts and tools inspections and pressure testing ensure that. In the prior art conventional types of spark plugs have a metallic center discharge electrode center electrode hereinafter which is formed of a nickel rod with a copper core or a nickel rod to which a tip of au pd alloy is welded.

A spark plug is a tool for delivering electric current from an ignition system to the flaming chamber of a spark ignition engine to light the compressed fuel or read more ceramic components buying guide 2020. Based on our 25year production experience and good facilities we can supply the total solution from the development design of new products to manufacturing assembling for diverse requirements. Selection of materials for both the electrodes and the insulator have consumed much research and development time and cost.
