Unveiling the Manufacturing Process: From Raw Materials to Finished Products
The production of Torch spark plugs is a meticulous process that involves a symphony of advanced technologies and skilled craftsmanship. Every step, from the selection of raw materials to the final quality control checks, is executed with precision and care to ensure that each spark plug meets the stringent standards set by NGK.
1. Raw Material Selection: The Foundation of Quality
The journey begins with the selection of high-quality raw materials, the building blocks of a reliable spark plug. NGK meticulously sources its materials from trusted suppliers, ensuring that they meet the highest industry standards.
Key raw materials include:
- Ceramic insulator: Provides electrical insulation and withstands extreme temperatures.
- Central electrode: Typically made of a corrosion-resistant alloy, conducts electricity to ignite the air-fuel mixture.
- Ground electrode: Completes the electrical circuit and creates the spark.
- Shell: Provides structural support and houses the other components.
2. Precision Machining: Shaping the Spark Plug
Once the raw materials are in hand, they undergo a series of precision machining operations. Advanced CNC (Computer Numerical Control) machines are employed to shape and form the various components of the spark plug with exceptional accuracy. (See Also: How to Install a Spark Plug Helicoil?
