Plastic pelletizing is a process that turns scrap plastic waste into usable raw material for production. This helps reduce waste and provides many benefits for manufacturing companies that utilize it. Plastic pelletizing can be used in blown film, pipe extrusion processes, and plastic products injection molding. It is a great way to save on the cost of new materials and help support green initiatives.
The main function of a plastic pelletizing machine is to transform the waste plastic into granules, which can then be repurposed in production for new products. This is done through a heating, melting and plasticizing process, followed by cooling and shaping into the desired shape. The machine can also be used to change the physical properties of the plastic, such as making it harder or softer.
There are several different types of plastic pelletizers, each with their own unique features and applications. The most common is the twin screw extruder, which is used for plastic modification, compounding and masterbatch production as well as for recycling and hard plastic reprocessing. This type of machine is capable of producing a very high-quality product with a very low amount of labor.
For softer or wet plastics, the underwater pelletizer system is ideal. This allows the granules to be pushed through a die while submerged in water, which cuts down on dust and other debris from the forming process. It also offers a higher level of automation and pellet uniformity than other types of plastic pelletizers.
Another popular type of plastic pelletizer is the single screw extruder, which is perfect for reprocessing squeezed and rigid plastic regrinds. This type of machine can handle a wide range of materials, including HDPE and LDPE. In addition to its versatility, this type of plastic pelletizer is easy to operate and maintain.
Depending on the needs of a company, there are three different cutting types for plastic waste pelletizers. The hopper feeding system is suitable for wet plastic materials and can be used with either soft or hard plastics. The cutter compactor integrated with the pelletizer can crush, dry and compact the incoming scraps, which makes it easier to feed them into the extruder screw. This allows for a continuous flow of material and eliminates the need for additional crushing.
For companies that produce a lot of waste plastic, there are a number of benefits to partnering with a plastic scrap recycling company to provide pelletized recycled plastics. These companies can help them cut down on their waste and create a more closed-loop recycling system. They can also purchase the scrap materials from manufacturers at a discount, saving them money in the long run.
