There are three type Machine direction orientation MDO stretching machine :

1. Small Machine Direction Orientor(MDO) & Casting film Machine

2. Vertical Machine Direction Orientor MDO Machine

3. Horizontal Machine Direction Orientor MDO Machine Pilot Line

Machine direction orientation MDO stretching machine adopts synchronous control technology, which makes the speed of cold stretching roll, preheating roll, hot stretching roll and annealing roll synchronously or proportionally adjustable in the production line of MDO stretching machine. Moreover, the motor of each roll can be controlled synchronously or independently through the knob. All parameter Settings, system control, data recording, etc., are operated or displayed through the human-computer interaction interface of the touch screen.
The main components of MDO stretching machine include cold stretching roll, stretching roll, hot stretching roll, annealing roll, cooling roll, rewinding roll, motor and reducer of each roll, etc.

Small extruder refers to small single screw extruder, small twin-screw extruder and small three screw extruder, is one of the main tools used in polymer processing and forming in laboratory, it can complete melting and plasticizing of polymer, extrusion function, cooperate with different mould, can extru different types of products, such as sheet, plate, profiles, pipes, films, etc.In order to improve the plasticizing effect and feed stability of the material, the small extruder can also be equipped with manual plate mesh changer, melt pump, static mixer, etc.The following are the main components of a small extruder:
