Plastic Strand Cold-cutting Granulating Machine

Plastic Cold-cutting Granulating Extrusion Machine is a piece of machinery specifically designed to extrude, cool, and cut molten plastic materials through a specific mold, ultimately forming regular-shaped particles. Plastic Cold-cutting Granulating Extrusion Machine basic working principle is as follows: First, after the plastic raw materials (usually waste plastics or recycled plastics) are crushed, cleaned, and dried are added to the machine's hopper, they are gradually transported forward under the rotation of the screw. The plastic is gradually melted and plasticized due to the external heating of the barrel and the frictional heat generated by the screw's cutting action. Under the pressure, the molten plastic is pushed through the specific-shaped molds (mold holes) inside the machine head, forming continuous strips. These strips are quickly cooled and shaped by water rings, water tanks, or air cooling systems, and finally, they are cut into uniform small particles by the cutting device, which are commonly referred to as plastic particles.

The application scope of Plastic Cold-cutting Granulating Extrusion Machine is very extensive, covering almost all common thermoplastic materials. Mainly including: Polyethylene (PE): such as high-density polyethylene (HDPE, commonly used in plastic buckets, bottle caps), low-density polyethylene (LDPE, commonly used in plastic films, hoses), and linear low-density polyethylene (LLDPE, also used in films, etc.).

Compression feeder
The hopper opening is compressed by the hydraulic system.
Check the internal operation with glass windows and lights.
Water cooling system - a water cooling system controlled by a magnetic valve
All materials in contact with the barrel are made of stainless steel.
 

Single screw extruder
The single screw extruder is made of a sturdy frame, heavy-duty. The machine runs without vibration;The milling work was completed on the entire frame which was equipped with a gearbox, motor and screws.The frame is made of square tubes and thick steel at the top.
 

Hydraulic screen changer
Dual-station mainboard model.
The audit committee proposed that 38crmnal forging and heat treatment will not deform after heating and can be used.

Vertical mold surface cutting system
The cutting speed is adjusted by the frequency converter
Frequency converter brand: Taiwan Delta
The blades are made of SKD-11 steel
The mold is forged from 38crmoala material and its surface is nitrided and polished.

Lead Time: According to quantity and seasons, the lead time is different.

1.Resource conservation and recycling: This is the core advantage.
2.Environmental protection: Waste plastics are the main source of "white pollution", causing severe harm to soil, water sources, and the ecological environment, especially to marine life.
3.Economic benefits are remarkable: The production cost of recycled plastic particles is usually much lower than that of virgin plastics. For plastic product manufacturers, using recycled particles can significantly reduce raw material costs and enhance product competitiveness.
4.Reduction of energy consumption: The energy required for producing recycled plastic particles is much lower than that for extracting and synthesizing virgin plastics from petroleum. According to statistics, using recycled plastics to manufacture products can save a significant amount of energy.
5.Promotion of industrial upgrading: The development of the plastic recycling and granulation industry has promoted technological progress, such as sorting technology, cleaning technology, and modification technology.
