EXCLUSIVELY IN THE WORLD-PATENTED DOUBLE VACUUM FEEDING TYPE EXTRUDER
Very low ampere when in full production. Energy-saving.
This system is researched and developed through several years ; it solves the biggest difficulty of material feeding for extruder. This system is world-wide patented, from Japan, China, Taiwan, Germany and other countries.
Patented by several countries ; counterfeit will be prosecuted.
Welcome to KOWIn for test-run ; international OEM requirement is welcome, too.
Three advantages :
1.Vacuum feeding system solves the problem of moisture in the plastic material.
2.Reduce the problem of IV value decrease for PET extrusion-pelletizing by 10 % more.
3.Reduce the problem of the material not feeding.
Technology & Feature
PET Recycling Extrusion Equipment
Manufactures the dominant PET Plastic Recycling and Extrusion Equipment in the industry. We fully understand and apply all the necessary processes for successful plastic recycling. Moisture removal, material compaction, and prevention of hydrolytic decomposition stabilize and increase intrinsic viscosity ( IV ) values of PET materials. The result - high efficiency manufacturing. The following describes some key features of our technology.
High Stability IV Values 1.Twin Hot Air Pre-Dryers : Continuous batch pre-drying. Numerous small batches increase efficiency, timer controlled.
2.Drying Drum : Synchronized dehumidifying and feeding, pre-crystallization, and crystallization increases PET IV value by 4 – 10 %.
3.First in, First Out Material Feeding : Avoids material flow stoppages.
4.KOWIn - DA Series Dryer : Honeycomb rotor simultaneously removes moisture, revives, cools ; efficiently gets dry air at dew point - 40 ° C.
5.Cast Aluminum Thermo-Regulator Jacket : Extruder thermostat displays air flow, increases area and speed of conduction, accurate temperature control within 3 - 5 ° C
6.Vacuum Extractor : Melt goes through vacuum extractor to have air and moisture removed, prevents bubbles and fish eyes in finished product.
7.High Speed Water Removal : After extrusion and cooling, product goes through a set of 4 high power blowers to immediately remove water and prevent residual surface moisture.
8.Crystallizing System : Directly after water is removed, flake enters pre-dryer and is crystallized for excellent pellet quality.
High Output Extruder 1.Gear Drive : 4 set gear drive for low noise and high torsion.
2.Forced Material Feed : Patented design, lateral pressure feed ; stable speed.
3.Hydraulic Screen Change System : Hydraulically controlled screen changes, designed to self check pressure to avoid leaks.
4.Sheet Extruder Die : Sheet level T-die and channel design.
5.Single Screw Design : Stable, rarely breaks down.
6.Frequency Conversion pelletizer : Uses production status frequency conversion to adjust speed, low material leakage.
Automated Control for Convenient, Easy Operation 1.Human Machine Interface : Direct operation, easy to learn. Interface is very clear and user friendly, data is safe and easy to store, very high fault tolerance.
2.Discharge Device : Turntable design discharges fixed amounts of material, includes inspection window.
3.Packaging Equipment : Vibrator automatically sets time control and continuous packaging.
Environmentally Friendly and Energy Saving : A Green Approach to Plastic Production 1.Revolving Honeycomb Dehumidifier / Dryer : Simultaneous dehumidifying and drying. regeneration and cooling. Regeneration temperature of 180 °C consumes 40 % less energy compared to conventional temperature of 230 °C.
2.Full Line Frequency Converter : System reduces load loss, rational voltage output saves at least 10 % - 15 % in electricity.
3.Packaging Equipment : Save wasted packaging space, increase packaging efficiency at least 5 % - 10 %.
