WPC Production Line

Extruder

The pipe extrusion line can be consisted by such accessory machine: main motor, the gear box, the distribution box, the barrel and screw, the dies, vacuum calibration tank and cooling tank.Main Motor is mainly to supply the power. The gear box can transfer the motor to power. The distribution box enlarges the strength of the power and realized uniformity. The barrel and screw work together to make sure the quality of extrusion. The dies shape the finish products.Vacuum calibration tank ensures the quality of product. Cooling tank makes the unit natural.

Polyolefin moulding

Lianda has accumulated 20 years experience on Pipe moulding. From design, production to testing, Linda owns a team of good technicians, have developed new-created 2-in-1 pipe and 4-in-1 pipe moulding. It can speed up the development of polyolefin production.

Vacuum Calibrator

Lianda's vacuum calibrator is made by stainless steel plates. The metal pips (inside and outside) use stainless steel pipes. With plastic adjustable sprayer and various internal pipes for adjusting the direction, the vacuum pressure inside can control the temperature and level of water, which can be controlled by setting system too.

Spray Cooling Bath

Lianda spray cooling bath is made in stainless steel material. Transparent soft PVC films are installed on both sides, can be pull up for easy control. Six rows of sprayers are inside and guarantee the surface of pipes having enough cooling. Internal water temperature control system provides suitable water temperature. Two-channels can keep normal production during the clean up of channel.

Haul-off Units

The haul-off units designed by Lianda for polyolefin pipes have different clipping power referring to different pipe sizes. The haul-off units can be designed in double-belts, triple-belts, four-belts, six-belts, etc. The belts have independent moving system and the clipping power is controlled by air pressure. Belts are following the direction of nylon slides. Stable with less vibration. Made in good materials and can be durable.

Cutting Devices

Lianda offers planetary saws for polyolefin pipes cutting. The saws are made in platinum steel. Different clipping system is used for different sizes of pipes to guarantee the stability of pipe cutting. We use Siemens PLC control system to provide an accurate cutting.

Co-Extrusion

It is very common to use co-extrusion in the polyolefin pipes production. We can provide two layers or many layers of co-extrusion pipes. The co-extruder can be connected with the main extruder or independent.
