New-type Patented Plastic Flat Thread Extruding Machine

Patent product; Better drawing ratio: 4-11 Make better plastic tape/yarn.

New-type Patented Plastic Flat Thread Extruding Machine

For a traditional extruding machine, it must change its chain wheel to change its drawing linear speed. However, the chain wheel’s size is fixed, which means one wheel stands for one speed. Users have to prepare different sizes of chain wheel for different speed. This causes low efficiency and high cost. For more, the speed is not accurate when changing by this way.

Now our new type extruding machine is adjustable for drawing ratio from 4 to 11, which is controllable and precise via free frequency conversion. It is no more necessary to change any chain wheel when changing its drawing speed. It’s an ideal machine for extruding plastic thread for making container sack, cement sack, chemical sack and so on.

The machine can extruder flat thread directly by using 100% recycled material in powder or granular form. Its screw and cylinder are made of 38CrMoAlA alloy after nitriding treatment, the hardness of which is up to HV950 or above. The speed reducer uses hardened helical gear reducer made of 20CrMnTi alloy; the chain wheel is made of 45# quenched medium carbon steel. The drawing roller is electroplated with hard chrome; the drawing system is additionally equipped with tension controllable rewinding shaft; and the feeding drum, three-way pipe and die head adopts aluminum cast heater that’s durable in use.
