The Wiscon Enviotech plastic recycling machine ranges from plastic shredders to plastic washing machines.
Plastic shredders are extremely flexible and Wiscon offers different rotor types, rotor geometries and screen, allowing the plastic recycling machine to downsize 3 major types of plastic scraps. Even if large-volume hollow bodies, long tubes and profiles, purges, huge start-up lumps and other production waste, as well as PET bottles, textile fibres, films, insulation materials, floor coverings, crates and containers, Wiscon can offer the right industrial shredders and granulators.
After size reduction, the goal of plastic recycling machine becomes washing and cleaning, which is a step to bring up the quality of plastic regrinds. Wiscon provides a total care from washing to drying.
The above plastic barrel recycling line is an example of the aforementioned processes.
Thermoplastics are a class of polymers that can be softened by heating and then processed by extrusion, injection molding, thermoforming and blow molding. Thermoplastics after cooling do not show any chemical changes after repeated heating and cooling, making them easy to recycle.
Advantages of thermoplastics include
Applications: medical apparatus, household kitchen ware, home appliance parts, chemical corrosion resistant parts, small and medium-sized containers and equipment, films, plastic ropes, and utensils.

Recycled plastic is the reuse of plastic, by carrying out shredding and granulation, so as to complete the reuse of plastic.
Recycled plastics are plastic materials that are reused after processing waste plastics through physical or chemical methods such as pretreatment (Plastic Recycling Machine), melt granulation, and modification.
It refers to the raw materials used are not contaminated at all, also called off-cut materials, also some are runners, sprue, and purgings. In the process of processing new materials, the remaining small edges, or bad-quality pellets. The recycled plastic pellets processed with these raw materials have better transparency and the quality of the recycled plastic pellets can be compared with new materials, so they are called first grade recycled plastic pellets or special grade recycled plastic pellets.
The raw materials have been used once, except for the high pressure recycled plastic pellets, which are mostly made of imported large parts. If the imported large parts are industrial films without exposing to the wind and sun, their quality is very good, and the transparency of the processed recycled plastic pellets is good.
The regrinds have been used twice or more, and the processed regrinds are not very good in terms of elasticity and toughness, and can only be used for injection molding. The first and second grade recycled plastic pellets can be used for film blowing, wire drawing and other purposes. In terms of quality, they can be divided into: wire drawing, film blowing, silk spraying, first grade, second grade, injection filling and so on. Sometimes the same grade is re-graded.

Engineering plastics are plastics that can be used as engineering materials and replace metals in the manufacture of machine parts and so on. Engineering plastics have excellent overall performance, high rigidity, low creep, high mechanical strength, good heat resistance, good electrical insulation. They can be used in harsh chemical and physical environment for a long time and can replace metal as engineering structural materials.
Compared with general-purpose plastics, they have excellent heat and cold resistance, excellent mechanical properties in a wide range of temperatures, suitable for use as structural materials; good corrosion resistance, less affected by the environment, have good durability; compared with metal materials, easy to process, high production efficiency, and can simplify procedures, saving costs; have good dimensional stability and electrical insulation; light weight, high specific strength, and have outstanding friction reduction and wear resistance.
Application areas: widely used in electrical and electronic, automotive, construction, office equipment, machinery, aerospace and other industries, plastic instead of steel, plastic instead of wood has become an international trend.
