In today’s fast paced manufacturing environment it has become very important to specialize.  Specialization is one of the many distinctions that makes Song Chuan unique in the relay industry.  Song Chuan ONLY produces relays, it is not just their main product, it is our ONLY product.  And they have been producing quality relays for 30 years.  They were the first Chinese relay manufacturer to become ISO certified back in 1994.  Song Chuan is QS9000 & ISO9002/14000 certified, and their quality improvement plan requires better quality performance each year.  Their automated relay testers for in-line and QA inspection have helped Song Chuan to exceed these quality improvement goals.  Song Chuan is dedicated to meet and exceed their customer’s requirements and expectations.  These are just some of the reasons that they produce the best relays in the world while still keeping the costs down and their relays affordable.
