Qingdao Leader Machinery Co., Ltd

Single wall corrugated pipe extrusion line:
It mainly uses PE, PP, PVC as raw material, through the corresponding moulds inside and outside produces smooth uniform corrugated pipes. The forming blocks made of hard steel, dealed with a rigorous use of CNC finishing materials produced to ensure that the hardness of the molding module and precision molding machine for the closed structure, module link in the overall closure base, in forming do from the running tunnels.
Produced pipes by the production line are mainly used in wire and cable products threading pipe, washing machine drains, vacuum cleaner, ventilation pipes, tubes, etc.


Wooden cases and wooden pallet

HDPE water and gas pipe extrusion line designed and manufactured by Leader Machinery based on years of experience, combined with the actual situation at home and abroad, has a beautiful appearance, a high degree of automation and stable production, well received by the customers.
Pipe produced by this line has excellent hardness and flexibility, heat resistance, aging resistance, high mechanical strength, environmental stress cracking resistance and creep resistance, hot-melt

Wooden cases and wooden pallet

Using a special screw design and enhanced plasticization effect of PP-R to ensure high-quality high-speed extrusion, high shear stress and low temperature to ensure that raw materials of high-performance plastics extrusion, the measurement on the feeder with the drying system to ensure that PP-R extrusion uniform.


Using wooden pipe and wooden pallet

Pvc/pe/wpc foam profile extrusion line
The line uses raw plastic material or recycled plastics (pvc, pe, pp) and wood fiber (wood powder and other plant fiber such as rice bran, straw, etc.) as the main raw material (the two accounted for more than 90%) the production of an industrial - wood plastic composites (wpc).
The product has the following advantages:
1. Wood-plastic composite materials instead of full-wood products, protecting forest resources.
2. Wood-plastic composites can use the stalks of plants, reducing environmental pollution
3. Wood-plastic composite material to eliminate white pollution, cleaning up the natural environment
The production line of products can be used for the production of building templates, building blocks toys with plates, trays, boxes, pallets and other packaging equipment; the end of plank, sleepers and other storage supplies, outdoor flooring, ra

Pvc wood-plastic foam door plate extrusion line
Pvc wood-plastic foam board plate made by this pvc wood-plastic foam plate extrusion line collects the advantages of wood and plastic. It not only has appearance of natural wood, but also overcomes shortcoming of wood, it has good processing performance which is similar to wood, it can be sawed and nailed. It can be finished with wood working tools. Its fixed force is clearly stronger than normal wood material.

Applications:
The products made by this machine can also be used in making building template, toy building blocks, tray, package box, sleeper, outdoor floors, railings, garden chars and other outdoor facilities, indicating plate, circulating box, rood beam and others.

This series of plastic sheet extrusion line is mainly used to produce extruded sheets from PE, EVOH, PA, EVA, PS, and PP materials. It comes with a single-screw extruder that heats, shears and conveys the material to an extrusion die as well as other shaping and cooling devices to obtain the final shape and size. Depending on the kind of material to be extruded, HANDERN would choose a different screw design with a particular length-diameter ratio, plus a suitable extrusion die. 

Auxiliary equipment on this extrusion line is similar to that of the PVC profile extrusion line. Processes that taking place on this multi-layer production line include the following:

1. Extrusion 
2. Shape formation with the extrusion die 
3. Cooling and sizing to obtain the final shape under vacuum or normal operating conditions
4. Conveying
5. Cutting
6. Discharging.




The resulting 5- or 7-layer PE, EVOH, PV, EVA, PS, or PP sheet provides a good air and moisture barrier for the food wrapped within it. It traps air between the layers, giving the best protection for the food. 

Parts
Conical twin-screw extruder, vacuum calibration table, conveyor, cutter, film applicator, and tilting rack, etc. 

Advantages
1. Optimal design of plastic profile extrusion equipment is critical to productive operations. Made with the latest technologies in the world, this extruded sheet production line offers many benefits including uniform plasticization, low shearing rate, high productivity, and a long service life. 

2. The main extrusion equipment uses an imported AC or DC adjustable speed drive. It is temperature controlled using the Japanese RKC temperature controller. The auxiliary equipment comes with a brand-name vacuum pump and a traction motor. All these parts are easy to maintain and repair. By simply replacing the extruder barrel and extrusion die, the extrusion line can produce wood-like extrusions that are actually irregular foamed profiles. 

Applications 
The corrugated sheet is often referred to as the hollow sheet in China. It is widely used in the jelly, high-grade meat product, instant rice packaging as well as medicine and cosmetic packaging industries.
