product parameter

3/4/5 Rolls calender machinery/ calendaring line for rubber and plastics industry

Machine application

It is used to produce various rigid, semi rigid or soft plastic films or sheets.

It can also be used to produce high filling plastic film or high filling plastic sheet.

Machine features

1.The machine is made of chilled castiron alloys,whose work surface has high hardness,so it is wear-resistant and durable.

2.While using,the steem,cooling water and heat-conducting oil can be passed into the roller's cavity,so that the working temparature can be adjusted in order to meet the technological requirement.

3.Roller space can be adjusted both by manual or electric mode.

4.Roller bearings' lubricating can adopt drier oil or dilute oil.

5.The film can infinite extend, with a high work speed, high produce capacity, good quality and uniform thickness.

6.The main machine has roll crossing, preloading and anti-bending device, the adjustment speed can be adjusted, the electric parts has PLC control.
