How to meet the requirements of quality, efficiency,cost and other aspects in automotive parts at the same time?

With the rapid development of economy ,science and technology, people’s living standards are improving constantly, more and more people begin to pursue high-quality life.

Automobile have already become the essential transportation in daily travel. As the automotive industry develops quickly, the requirements of automobile parts quality by major automobile companies are getting higher and higher.

Therefore, a practical problem for each major automotive parts manufacturers: How to improve processing efficiency and effectively reduce the cost on the premise of ensuring product quality?

Automotive air conditioning expansion valve

Automotive air-conditioning system was born in the 1920s and has been developed for nearly 100 years. Now automotive air conditioning has become one of the standard configuration for automobiles. automotive air conditioning expansion valve is an important component of automotive air conditioning refrigeration system, there are four holes ( A,B,C,D ) in valve body, the carbide cutting tools were used to process these holes in the past. As the market competition becomes more and more fierce, the disadvantage of carbide cutting tools begin to appear: the hole roughness and tool life are not good.

In this background, Shanghai Nagoya’s technology R&D team has produced and developed a PCD cutting tool with special optimized design. When it process four holes in the air conditioning expansion valve, the roughness of hole can be achieved Ra0.2 and also the tool life is double.

Shanghai Nagoya has maintained long term cooperative relations with each major automobile manufacturers and automotive parts suppliers, providing them with high-quality, efficient and precision special PCD cutting tool and solutions!
