Here is the introduction of variety of coil springs, wire formed springs, and other special springs.
There are various types of springs by their shapes. Our extensive production facilities enable us to produce from micro precision springs to hot formed springs, and from trial to mass production. Customers who need a small amount of springs, we recommend our standard stock springs. In case we can't cope with your requests, we could introduce you to other companies that satisfy your requests.
We guide our customers to order manufactured-to-order springs for the first time.
Please contact us anytime 24 hours via emails. Our sales department will respond within 24 hours for confirmation, and we strive to respond quickly to submit estimates in principle within 48 hours after confirming the specifications.
We always listen closely to our clients' inquires and requests to solve problems or to develop new clients. Now we receive orders from various industries nation-wide. Not only we consult via emails, but we also visit our clients if necessary.
Here is a sum-up of frequently asked questions upon estimates and orders. There are answers about drawing, designing, delivery term, quantity, tooling costs, quality management and purchase of standard products. If you have any other questions, please feel free to contact our sales department.
We summarized some frequently asked elementary questions about spring materials and common springs.
Technical data displays basic formulas and symbols used for spring design.
Three important points in order to make a better spring;1. To design properly, 2. To choose the best materials, 3. To produce correctly and accurately.
