Process Flow

PE resin + color masterbatch → mixing → vacuum feeding → drying → extruder plasticizing (180-210℃) → mold forming → vacuum calibrating → multi-stage spray cooling → laser printing → pull off traction → fixed-length cutting → finished product stacking

Product Parameter

Product details

1. Material Feeding and Drying:	(1) This PE material will automatically convey to the extruder's drying hopper via a vacuum feeder (2) where moisture is removed to make sure the PE material's moisture content keeps below 0.1%, then guaranteeing the product quality.
2. PE Pipe Extruder:	Equip with SJ75/33 high-efficiency single-screw extruder (1) integrates 55KW energy-saving servo motor which can reduce power consumption by approximately 20%. (2) direct-drive gearbox which can ensure high transmission efficiency and simplified maintenance. (3) wear-resistant and corrosion-resistant screw barrel which forged from 38CrMoALA alloy steel with precision nitriding treatment. (4) efficient infrared heating coil system (5) automated temperature control system which features Omron’s high-precision temperature controller.
3. Marking Line Extruder:	(1) The SJ25 extruder is utilized to create marking lines on PE pipes. (2) Producing either a single marking line or multiple marking lines, and depending on the customer's requirements.
4. Specialized PE Pipe Mold:	(1) With basket or spiral structure die head (2) Ensure the uniform extrusion of the material.
5. Vacuum Calibration Tank:	(1) The extruded tube blank undergoes rapid precision calibration though vacuum adsorption, ensuring strict dimensional accuracy. The vacuum level can maintain at 0.06–0.08 MPa. (2) The tank is constructed from food-grade stainless steel, and features a multi-zone vacuum control system and efficient water circulation cooling. They collectively guarantee consistent pipe roundness, smooth surface finish, and adherence to tight tolerance standards throughout high-speed production.
6. Spray Cooling Tank:	(1) It uses multi-stage spray cooling technology and maintains water temperature below 20°C. This tank can ensure rapid and uniform cooling of pipes. (2) It is constructed from stainless steel and provides excellent corrosion resistance and durability.
7. Pull-off Traction Machine:	(1) This machine can make draws pipes at a steady speed (3-15 m/min) to ensure uniform length and stable production. (2) This machine is equipped with precision control systems, it can keep consistent tension during the traction process, effectively prevent pipe deformation and ensure dimensional accuracy.
8. Planetary Cutter:	(1) Enables automatic fixed-length, chip-free cutting with smooth, burr-free edges (2) Specifically optimized for small to medium diameter PE pipes (3) Ensures consistent length accuracy and minimizes material waste during production by its precision cutting mechanism.
9. Laser printing machine:	(1) Show the product specifications and batch information in real-time using laser technology (2) No consumables required.
10. Stacking Rack:	(1) It can automatically stack finished pipes in an orderly manner (2) It equips with adjustable stacking height and layer count, and then accommodate different pipe lengths and storage requirements.
11. Electric control system:	(1) including ABB frequency converters (2) Siemens contactors (3) Omron temperature controllers (4) and Inovance servo controllers
