? With conventional spring is slightly different spring itself is irregular, curved angles and a lot of complex manufacturing and processing technology is relatively Design, is required, the device is more required is a computer machine · General · due to winding wound multi-angle, bending and more, so production is slow · its complexity, shaped spring production and processing can often represent a company's technical level. Common spring into: compression springs, tension springs, torsion springs shaped spring, shaped spring main point of view is that there is a complex space, irregular bending and so on.
