The table type single screw extruder can be used together with the table type film casting machine and the table type film blowing machine to complete the forming test of film products under the condition of very little amount in the laboratory

Principle
Simulate Production Realistically on a Laboratory Scale ,single screw measuring extruder serves for testing the extrudability of polymers and for studying thesis occurring in research and development as well as in practical application. The single screw extruder system allows a complete instrumentation of the extruders for the control and development of raw material. Different screws, die heads, and downstream equipment fulfill all kinds of extrusion tasks.
Application
In the measuring extruder , the sample material is plastified under practice-oriented conditions and extruded through the die head. All measuring values such as torque, melt temperature, melt pressure are recorded continuously and represented in the form of tables and diagrams parallel to the current test. The extrudate is tested for various criteria:
• Uniform plastification, gloss, gels
• Color dispersion and color matching
• Transparency and formation of streaks, e.g. with transparent materials
• Swelling and contraction behaviour
• Segregation of individual recipe components of a compound at the die and/or at the screw`s tip
(e.g. titanium dioxide)
• Output per unit of time, etc.
 
Drive device
It is mainly used to complete the plastic plasticizing and transportation by uniform rotation for torque setting,Servo motor control screw torque, pre-set torque from touch-screen.
Feeding device
Material depend on its own gravity from the hopper into the screw barrel .According to the properties of material production and processing technology conditions, adjust the volume of feed speed and extrusion in order to achieve the balance.                           
Barrel
It contains materials and screw.
