Hot-melt plastic pelletizing production line

Introduction Extruders are classified into angled heads (with a 120° angle) and straight‑angle heads, depending on the angle between the material flow direction at the die head and the screw’s central axis. The die head housing is bolted to the extruder body. Inside the head, the die includes a die core holder, which is secured with nuts at the feed port; a die core is mounted in front of the holder, and both the core and its holder feature central holes for passing the core wire. A pressure‑equalizing ring is installed at the front of the head to balance internal pressures. The extrusion‑coating section consists of a die sleeve holder and a die sleeve; the position of the die sleeve can be adjusted via bolts and supports, allowing precise control over its relative alignment with the die core and facilitating uniformity in coating thickness. External heating and temperature‑sensing devices are also incorporated. Applications and Features: Depending on the screw design and mechanical configuration, this equipment can process sheet or pelletized materials such as PP, PE, PS, PET, ABS, PC, acrylic, and others. It is suitable for producing pellets from virgin resins as well as recycled materials. The granulator offers excellent processing performance, low manufacturing costs, corrosion resistance, electrical insulation, high precision in pellet cutting, efficient hot‑cutting, and easy installation and mobility. The twin‑screw version provides secondary filtration and superior venting, yielding dense, brightly colored pellets with excellent plasticization. Functions and Applications: With specialized screw designs and various configurations, this machine is ideal for producing regenerated and color‑blended pellets from a wide range of plastics, including PP, PE, PS, ABS, PA, PVC, PC, POM, EVA, LCP, PET, PMMA, and more. Its gearbox features a high‑torque design, ensuring quiet, smooth operation. The screw and barrel undergo special hardening treatments, providing wear resistance, superior mixing capabilities, and high production output. Equipped with either vacuum or standard venting ports, it effectively removes moisture and exhaust gases during processing, resulting in more stable discharge, stronger pellets, and consistently high product quality. Plastic pelletizing machines are primarily used to process waste plastic films—such as industrial packaging films, agricultural mulch films, greenhouse films, beer packaging, shopping bags, and more—as well as woven bags, agricultural convenience bags, basins, buckets, beverage bottles, furniture, and everyday household items. They handle most common types of waste plastics, making them the most widely used, versatile, and popular machinery in the plastic recycling industry.

Hot-melt plastic pelletizing production line

Introduction

Extruders are classified according to the angle between the die flow direction and the screw centerline, with dies divided into angled dies (angle… 120°) and a right-angle head. The head’s housing is made of snail plug The die is fixed to the machine body, with a die‑core holder mounted inside the die head and secured to the wire‑entry port by a nut. A die core is installed at the front of the core holder, and both the die core and its holder feature central holes for the core wire to pass through. A pressure‑balancing ring is fitted to the front of the die head to equalize pressure. The extrusion‑molding section consists of a die‑holder assembly and a die sleeve; the position of the die sleeve can be adjusted via bolts and supports, allowing precise control of its relative alignment with the die core and facilitating uniformity in the thickness of the extruded coating. External heating and temperature‑measurement devices are also provided.

Applications and Features:

Depending on the screw design and mechanical configuration, it can be applied to PP, PE 、 P.S. 、 PET 、 ABS 、 PC , granulation of acrylic sheet or pellet materials . It processes both virgin and recycled materials, and the pelletizing machine boasts excellent processing performance, low manufacturing costs, corrosion resistance, electrical insulation, high pellet‑cutting precision, superior hot‑cutting efficiency, and easy installation and mobility. The master–slave unit features secondary filtration and effective venting, producing pellets that are dense, brightly colored, and well plasticized.

Function and purpose:

Employing a specialized screw design and various configurations, it is suitable for production. PP, PE 、 P.S. 、 ABS 、 PA 、 PVC 、 PC 、 POM 、 EVA 、 LCP 、 PET 、 PMMA Recycling and color‑blending pelletizing of various plastics. The gearbox features a high‑torque design, delivering quiet operation and smooth performance. The screw and barrel undergo specialized hardening treatment, offering excellent wear resistance, superior mixing efficiency, and high production output. With either vacuum venting or standard venting options, moisture and off‑gases can be effectively removed during processing, ensuring more stable discharge, stronger pellets, and consistently high product quality.

Plastic pelletizing machines are primarily used to process waste plastic films—such as industrial packaging film, agricultural mulch film, greenhouse film, beer‑packaging film, and shopping bags—as well as woven bags, convenient agricultural bags, pots, buckets, beverage bottles, furniture, and everyday household items. They are suitable for most common types of waste plastics and are the most versatile, widely used, and highly favored plastic recycling equipment in the industry.
