Advantages
☆ The domestic first-class technology and core operating team, each member has rich experience with processing more than 5000 sets of corrugated roller. Depending on the mature stable Taiwan craft technology and the advanced international technology, we offer the optimized design of corrugating roll flute profile totally according to costumer’s requirement.
☆ The CNC intermediate frequency heat treatment quenching machine adopts the foreign corrugating roll quenching technology and makes the hardness of the substrate reach more than HRC58 degrees, meanwhile it retains the toughness and maximizes the anti-thermal deformation of substrate to ensure the stability of corrugating rolls.
☆ The leading domestic high precision and high performance CNC corrugating roll precision grinders, lathe, planer, and other equipment are equipped with Germany's Siemens control system, increase grinding accuracy in the maximum.
QC
Before and after the surface treatment including tungsten carbide plating or hard chrome coating of corrugating rolls, it is needed to check the size, hardness, precision, flute profile, and simulation feeding paper. Special projector is used to check the flute profile and feeding different GSM paper to ensure the performance of corrugating rolls.
