In the field of plastics processing, plastic granulators and plastic pellet cutter are two common pellet maker equipment, that play an irreplaceable role in the process of plastics processing. Although their functions are both related to the production of plastic pellets, there are obvious differences in their working principles, roles and application scenarios. In this article, we will compare plastic granulators and waste plastic cutter machines and discuss the differences between them in detail.

Plastic pelletizer: heating and melting plastic extrusion into strips

Plastic pelletizer, also known as plastic pelletizing extruder, is a kind of pellet maker equipment used to melt plastic raw materials by extrusion after heating to form plastic pellets. The principle of operation is to melt the plastic raw material by heating it to a certain temperature, and then extrude the molten plastic through the die opening in the head of the extruder to form long strips of plastic. These plastic strips can have different shapes and sizes, depending on the mold used.

Plastic pellet cutter: cuts the plastic strips into pellets

A plastic cutter machine is a type of pellet maker equipment used to cut plastic strips extruded from a plastic pelletizer into uniformly sized pellets. Its main function is to quickly and accurately cut long strips of molten plastic into pre-determined-sized pellets. These pellets are typically used in the manufacture of plastic products or as a raw material for other processes.

Differences between the two types of pellet maker equipment

Functional differences

The main function of plastic pelletizers is to heat and melt plastic raw materials and then extrude them into plastic strips. The main function of the plastic cutter machine is to cut the plastic strips extruded from the plastic pelletizer to form plastic pellets of uniform size.

Different working principle

Plastic granulator prepares plastic strips by extruding the heated and melted plastic raw materials. Plastic dana cutter cuts plastic strips by rotating blades or cutting device to form pellets.

Different scope of application

Plastic pellet making machine is suitable for the preliminary processing of plastic raw materials to prepare plastic strips, commonly used in plastic recycling and plastic product production. Plastic cutter machine is suitable for cutting extruded plastic strips, usually as part of the plastic pelletizing line, also commonly used in the recycling of waste plastics.

Different operation flow

The operation process of plastic pelletizers mainly includes feeding, heating and melting of plastic raw materials, extrusion molding and other steps. The operation process of waste plastic cutter machine mainly includes adjusting cutting parameters, starting the equipment, cutting plastic strips and other steps.
