Polymer Film; Thicknesses from 0.5 mm to 12.5 mm Used to obtain flat products and semi-finished materials for thermoforming Film: Thicknesses are under 0.5 mm. Packaging materials (for packaging, shopping bags, garbage bags, etc.) Thicker films can be used in applications such as pool linings. All thermoplastics, Polyethylene, mostly low density PE Polypropylene (PP) Polyvinylchloride (PVC) Cellophane Sheet and Film Production Methods Most commonly used mass production methods: Slit Die Extrusion Slit-Die Blown Film Extrusion, Rolling Calendering Slit Die Extrusion films are produced using the extrusion method with the aid of a die containing a thin slit The slit can be up to 3 m wide and as narrow as 0.4 mm. The polymer melt undergoes very large deformations during flow and therefore it is difficult to obtain a constant product thickness across the width. Since the edges are thicker, the edges usually need to be trimmed.

 

 

General Parts

 

It consists of extruder driven motor, gear reducer box, screw and barrel, aluminum casting heater, cooling fan, roller, mold, hopper and control cabinet.

 

 

Working Principle

 

The working principle of the extruder is as follows: The product moves in the hot line. In this way, it reaches the required temperatures and mixtures to form a homogeneous melt. The pressure created then forces the melt through the extruder. It comes out in the form of a mold.

 

 

What is a Melt Pressure Sensor?

 

Melt Pressure Sensor is an instrument used to measure the pressure and temperature of melted liquids (optional) in processes where plastic raw materials can reach high temperatures.

 

 

 

Why is a Melt Pressure Sensor Necessary?

 

Almost all extruders use at least one melt pressure transducer because it is desirable for melt pressure/temperature control to improve the quality of the extrusion process.

Melt Pressure Sensor Applications for Packaging Extruder Processes;

 

Melt Pressure Sensor in Mold / Melt Pressure Control Application

 

Aim:

 

*Checking the melt pressure, flow stability,

 

* To ensure the formation of the necessary pressure for production,

 

*Creating necessary prescriptions for production,

 

* Evaluation of plastic raw materials,

 

*Controlling Pressure,

 

*Preventing excessive pressure on the screw,

 

* Protecting screw wear,

 

* To prevent possible mechanical deformations.
