úvod

Founded in 1976 as a manufacturer specialized in Volute Springs, S Springs, Springs, CNC Parts and Stamping Parts. To ensure our quality, we purchase the material directly from Taiwan China Steel Company; manufacture of parts has been fully automated.
After almost 40 years of experience, we have acquired more technology and better quality, as being the main supplier of Taiwan Automobile Factories. Our products are exported to Thailand, Malaysia, Indonesia, China, United States and other countries. For service convenience for our overseas customers (especially Japanese Automobile Factories in Thailand), in 2004 we set up a factory in Thailand.
