EPE foam extruder(Epe Foam Sheet Extruder) is mainly composed of the following main parts:

1.Screw: It is refined from 38CrMnALA nitrided steel. Heat treatment quenching and tempering and nitriding treatment and surface treatment chrome plating make the screw have the characteristics of high strength and high surface hardness, thereby improving the service life of the screw. The L / D  ratio is 55:1, which improves the plasticizing ability and quality of the screw.

2.Barrel: Refined from 38CrMnALA nitrided steel. After heat treatment (quenching + nitriding), it can prevent long-term use loss. The barrel is connected to the feed section and the die device by a flange.

3.Material feeding section: The two ends of the feeding section connect with the screw barrel and gearbox. The raw material enters the extruder through this part. The user should keep the cooling water cycling continuously to prevent the temperature from going up. If the temperature goes up, the raw material will be sticked and block the feeding mouth.

4.Main motor of the EPE foam extruder: The main motor is an AC motor with variable frequency and speed, which is cooled by air (with fan). The main motor is connected to the main extruder screw through a gearbox.

5.Butane input and butane pump: The butane pump is a high-pressure metering pump. This pump injects liquefied butane into the barrel at a high pressure of 10-40Mpa. Butane and melted LDPE are mixed in the entrance of the screw barrel where there is a one-way valve to ensure that the melted LDPE will not reverse flow when the barrel pressure is greater than the butane pressure, ensuring production safety.

6.Anti-shrinking agent input and anti-shrinking agent pump: The anti-shrinking agent pump sent the anti-shrinking agent into the screw barrel after heating it. The melted anti-shrink agent and LDPE are mixed in the anti-shrink agent feeding section. The feeding part is equipped with a one-way valve, so that the melted LDPE will not reverse flow when the barrel pressure is higher than the pressure of the anti-shrinking agent to ensure production safety.

7.Die part: The melted raw material is extruded from this part. The raw material begins to foam as soon as it passes through the die lip. The thickness of the EPE pearl cotton sheet depends on the die lip and the pulling speed.

8.Size-setting drum: The width of the EPE pearl cotton sheet is determined by this part, so cooling water and cooling air should be provided in this part.

9.Tractor roller: The sheet stretched by the sizing drum enters this section for traction. At this time, the traction speed should be balanced to ensure the quality of the sheet. The diameter of the traction roller is φ350 ～ 2200mm, and it is equipped with a variable speed motor to adjust the traction speed.

Double-station automatic meter counting overturning and winding machine: This section is equipped with a meter counter that can set the length of the sheet. When the length of one roller reaches the set requirement, it can overturn 180 °automatically and the second roller starts working while the first roller stops. 

Epe Foam Extruder,Epe Foam Sheet Extruder

Our EPE machine(Epe Foam Extruder,Epe Foam Sheet Extruder) adopts innovative technology and it can be operated full-automatically. It is equipped with an automatic thickness adjustment device. It can also change the net automatically without stopping the machine or break the sheets.  The electrical control system is selected from well-known international brands, The temperature control system is digital display type and the temperature can be controlled automatically, the motor is explosion-proof type, the machine is controlled by frequency controller, there is also recycling cooling water to cool the barrel, so the whole line is energy saving, high efficient, safe and stable. 

The products made by our Epe foam extruder(Epe Foam Sheet Extruder) are white and delicate with high foaming ratio. The customer can also change different mould and auxiliary machines to make other products such as foam pipes, foam rods, foam nets, foam profiles, etc to achieve one machine with multiple purposes.
