Ceramic Spark Plug Manufacturing Process

Ceramic materials ceramic materials cannot be formed by the manufacturing processes known from metallic or organic materials.

Ceramic spark plug manufacturing process.

Established in 1995 shengda ceramic employs 70 employees. A process for preparing a spark plug insulator blank by dry pressing a powdered ceramic composition mainly comprising metal oxides comprising the steps of. 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. 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.

Specifically designed to reduce quenching. The process used to form ceramic materials is a heat treatment of very fine powders of the raw materials called sintering. Ngk spark plugs provide better ignitability and quicker starts. Manufacturers test incoming parts and tools inspections and pressure testing ensure that.

Each major spark plug component is manufactured in a continuous line assembly process. With over 35 years of ceramic production experience alumina ceramic components inc. It forces the spark to jump the gap which initiates combustion. 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.

Shengda ceramic is located in yixing china with an area of 4 000 square meters and fixed assets of over 1 million us dollars. The ceramic insulator is the only barrier between the electrodes keller says in the release. Selection of materials for both the electrodes and the insulator have consumed much research and development time and cost. In every case you ll speak with the same person when you contact us as we work toward fulfilling your order.

The energy to melt and cast ceramic raw materials would be far too costly. 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. The present invention relates to a spark plug having a novel center discharge electrode and a manufacturing process thereof. 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.

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. Manufacturers implement quality control standards and practices throughout the process to ensure accuracy and safe manufacturing so that spark plugs can fulfil their function. Ngk is the world s largest oe supplier and manufacturer of spark plugs.
