We first began supplying to our customers in the beginning of 2008. Presently, we have more than 50 machines used for making coil springs of diameters ranging from 0.08 to 40. We are specialised in making precision springs. The person-in-charge of coil springs has more than 30 years of experience (and he has been stationed in Thailand for the past 20 years). Other post-processing services include gold plating of the springs.
