After decades years of reseach and development in piezoelectric field, we have also entered the piezoelectric application in knitting textile machinery parts area. We have successfully broken the Karl Mayer's dominance in warp knitting machinery pieoelectric jacquard comb products#E4, E8, E12, E22 line according to Karl Mayer machine code K2, K3.... Our Karl Mayer compatible piezoelectric jacquard bar has been widely accepted by the market since we started the products sale in market from 2008. Above progress is based on our years development in wac data 3700/3800 system piezoelectric spare parts reaseachand good market performance. Our wac data spare parts includes piezoelectric ceramics plates , lonati matrix drum board, piezoelectric actuator ...
