The screw is a BM separation type high-speed extrusion screw, the material is high-quality alloy steel 38CrMoALA, the surface is nitrided, the depth of the nitrided layer is 0.4-0.7mm, the hardness is HV840-1000, the brittleness is not more than 2 grades, wear resistance, corrosion resistance, high strength, and good plasticizing effect. The reducer adopts plastic special hard tooth surface reducer, with oil pump forced lubrication cooling system, large torque, high load capacity, stable transmission, low noise, long life and so on. Fuselage temperature control system adopts new ceramic heating ring heating and energy-saving axial flow fan cooling device



1) The spiral structure is a new technology that is gradually improved based on the company's more than 20 years of experience in optimizing architecture design.

2) Using 45# mold steel, the mold has high hardness and strong rigidity, and is not easy to deform under high temperature and pressure. The spiral flow channel adopts multi-layer spiral flow, polished and chrome-plated, the flow channel is smooth and smooth, and the resistance is small. The clockwise rotation direction is just opposite to the screw rotation direction, which can relieve the stress of the released material during extrusion and improve the strength of the pipe.

3) All kinds of new and old polyolefin plastics can be used, which reduces the base pressure, uniform plasticization, stable extrusion, and all indicators of the pipe meet the standards. It is a stable product obtained by processing various specifications of pipes at low melting temperature, high output, and low energy consumption.



The sizing sleeve plays a role in shaping the PE pipe and quickly dissipating heat during production. If the heat cannot be

dissipated quickly, it will cause the PE pipe to stick to the sleeve and break the pipe, resulting in the vacuum pressure release

in the vacuum box, resulting in production interruption and waste.

1) Materials: copper, stainless steel, iron hard chrome plated 2) Calibration sleeve: The company's unique design, after turning

and grinding, makes the inside and outside as smooth as a mirror, stable in shape and accurate in size.



1) The vacuum sizing box plays a key role in sizing and cooling in the vacuum insulation pipe production line. The box body is made of 201 stainless steel, and each pipeline is made of 304 stainless steel. The spray system uses ABS atomizing nozzles, with automatic drainage, automatic water level control, dual-channel water supply, waterproof LD lighting inside the box, and automatic frequency conversion adjustment device for vacuum degree.

2) The vacuum device adopts a water ring vacuum pump, and the vacuum degree is generally controlled at -0.01 to -0.08MPa. The water level of the water tank is automatically controlled, and the entire operation process is automatically completed, saving manpower and material resources and improving production efficiency.

3) In order to prevent water shortage and high water level, there is an upper and lower limit alarm function for water level. When there is water shortage or high water level, it will give an audible and visual alarm to remind the operator


according to pipe diameter range or machine model, can equipped with two claws, six claws, eight claws, ten claws, twelve claws, fourteen claws, sixteen claws, eighteen claws, twenty claws etc.


1) The crawler tractor adopts radial symmetrical and uniform distribution, and the clamping and loosening is adjusted by the slider screw. Each traction arm is directly driven by an independent motor, and the independent motor is directly connected to the RV reducer. The chain and the drive shaft are eliminated, which reduces energy consumption.

2) The box body is made of cast iron, which is more durable and stable than cast steel. Silicone rubber blocks, steel frame, frequency conversion speed control, stable traction.



1) The planetary cutting saw is composed of a frame, a moving body, a rotary assembly, a clamping structure, and a cutting structure.

2) After the clamping mechanism clamps the product during cutting, the main body of the cutting saw moves backward on the rail of the frame under the action of the clamping force. The cutting blade on the rotary assembly revolves and cuts while feeding under the action of the hydraulic feeding system. The cutting of a working cycle is completed through the control of the limit switch. The electrical control system has a separate man-machine interface PLC, programmable system control, the entire operation process is completed automatically, the cut section is vertical and neat, and no secondary processing is required.


The role of the hosting device is to lift the uncut PE pipe. With the production of the PE pipe, it moves on the roller to prevent the surface of the pipe from being damaged and bent. The height can be adjusted according to the needs of the screw, and the length is 5 meters * 2 sets

SIEMENS PLC Programmable Control System

The operation of the main engine adopts SIEMENS Siemens PLC and touch screen for programmed control. It is equipped with a good man-machine interface, all process parameters can be set and displayed through the touch screen, and there is a fault storage page for easy query.
