As people more and more demand for polymer functional materials research and development, lab extrusion molding equipment reliability is also more and more get the attention of the enterprises, research institutes and universities, is no longer the previous point of view: "I have, and it can work is ok", but a small extrusion equipment in laboratory is required to have the technical characteristics as production line, and some of the user is completely according to the production line to simulate the custom of experimental equipment. The commonly used polymer processing and molding equipment includes: small extruder, small cast film machine, small calender machine, small blown film machine, small laminating film machine and so on. As the most important part, the performance of small extruder directly influences the experimental results.

The lab small blown film machine consists of single-layer small blown film machine and multi-layer small blown machine. It is mainly composed of single or multiple small extruder, single-layer or multi-layer blowing mold and small-sized blowing auxiliary machine. It can customize single-layer, double-layer, three-layer, five-layer and seven-layer small blowing film machine according to needs.

Lab small cast film line is combine withlab small extrder, cast film cooling roll, traction roll, slicer knife, constant tension winding system, all these made of a lab small cast film line, it complete plastic particle monolayer or multilayer extrusion cast film process.

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.
