Special Processes
Special manufacturing is a key process in the aerospace manufacturing industry. Most product manufacturing processes rely on various special manufacturing processes to meet functional and quality requirements. JYR has made every effort to develop our aerospace products in the best possible way: obtaining certifications for non-destructive testing, metallographic testing, mechanical property testing, vacuum heat treatment, chemical processing and welding. JYR also strives to partner with other companies to optimize and integrate their resources in order to fulfill customers' needs.
