ISO9001/CE Φ420×2020 embossing roller
We are professional in embossing rollers because of more than 25 years rich experience.
Description:
Qiaode utilizes calender rolls made of special chromium-plated steel, obtained from a single forged ”monoblock” completely machined, granting stiffness and a perfect dynamic balancing: the result is a higher stiffness of the rolls under process load.
Applications:
Description:
Calender Material | High-quality alloy steel. |
Heating Style | Peripheral holes, the heating speed is fast and the surface temperature of roll is even. |
Roll Diameter | Φ380-φ850 |
Pattern | Square, round, rhombus,ellipse, cross, stripe,etc. |
Calender Maximum Line Pressure | 150kg/cm2 |
Competitive Advantage:
After-sale service
Moreover the two operating rolls are designed with an outside diameter which is “almost” equal, and which always grants a similar rotation speed(r.p.m), avoiding spotted wearing phenomena. This configuration allows to avoid any dynamic unbalance and grants constant temperature on the whole steel roll (not higher than +/-1 °C on the whole working surface)i.e. a homogenous thermal exchange (thermal bonding effect) on both sides of the web. Therefore, also increasing the speed, there is always a balanced ratio and consequently a perfect mechanical stability. In addition “monoblock” roll shape grants easy maintenance and long life utilization.
