As a manufacturer specializing in plastic pelletizing machines (plastic granulator) for over 20 years, Laizhou Keda Chemical Machinery Co., Ltd. ensures genuine quality at competitive prices. We offer a wide variety of plastic pelletizing machines, categorized based on different criteria as follows ( Specific details depend on the buyer’s requirements and applications.) ,
1, By Application Scope: Granulators are categorized by their role in the production line.
· Beside-the-Press Granulators: Compact units designed to reclaim sprues, runners, and rejected parts directly at the injection molding machine, enabling immediate reuse of material.
· Central/Centralized Granulators: Larger, more powerful systems built for processing high volumes of various scrap materials from multiple sources in a centralized location.
· Heavy-Duty Granulators: Robust machines capable of handling the toughest challenges, like thick-walled parts, purgings, and large lumps of plastic.
2, By Cutting Mechanism: The nature of your plastic determines the best cutting method.
· Shear-Cut Granulators (Blade Granulators): Use a scissor-like cutting action. They are versatile and can handle a range of materials, from thin films to rigid parts.
· Nippers (Screenless Granulators): Operate at low speeds using a crushing and tearing action. They are ideal for engineering plastics, brittle materials, and glass-filled compounds, as they generate less dust and noise.
3, By Pelletizing System: This determines the final shape and quality of your recycled pellets.
· Strand Pelletizing (Cold Cut): The extruded polymer is cooled in a water bath, dried, and then cut. It is a classic, simple method but requires more space and is sensitive to the melt strength of the plastic.
· Die-Face Pelletizing (Hot Cut): The molten polymer is cut immediately as it exits the die and then cooled. This includes Water Ring, Underwater, and Air-Cooled systems, which are faster and more automated, ideal for high-volume processing of thermoplastics.
