This article provides a complete maintenance guide for plastic pelletizing machines, covering daily inspections, periodic servicing, and emergency troubleshooting. It explains how proper lubrication, temperature control, electrical checks, and routine cleaning can prevent common failures such as material blockage, motor overheating, pellet contamination, and screw wear. The guide also outlines monthly, quarterly, and annual maintenance tasks for the hydraulic system, screw and barrel, gearbox, and electrical components. With practical steps for handling sudden issues like jamming, impurity-contaminated pellets, and overheating motors, the article helps manufacturers extend machine lifespan, reduce repair costs, and ensure stable, high-quality pellet production.

This article discusses the selection principles and specific applications of plastic additives. Additives should be chosen based on the intended purpose, ensuring they can fully perform their functions and meet the required standards and performance specifications. Various types of additives and their applications are listed, including toughening, reinforcing, flame retardant, antistatic, conductive, magnetic, thermal conductivity, heat resistance, transparency, wear resistance, insulation, and barrier properties. The selectivity of additives for different resins is also addressed, highlighting the effectiveness of red phosphorus, nitrogen-based flame retardants, nucleating agents, and glass fiber heat resistance modifiers for specific resins. For example, red phosphorus is effective for PA, PBT, and PET, while nucleating agents work well for copolymer polypropylene.

The plastic granulator is a kind of equipment commonly used to produce plastic granules. The temperature regulation of each area is very important for product quality and production efficiency. The following will introduce in detail the temperature regulation method of each area of the plastic granulator.

Plastic granulator machines have revolutionized the way we handle plastic materials. They enable us to transform plastic waste and raw materials into manageable granules, reducing waste and contributing to sustainability. This guide aims to provide a comprehensive understanding of plastic granulators, their advantages, and their crucial role in promoting efficiency and sustainability.

Happy Chinese New Year!

Many thanks for your contiguous supports in the past years, we wish both business snowballing in the coming years.

The extrusion machines in the domestic plastic industry are roughly divided into two categories: single screw extruder and twin screw extruder. Because these two types of equipment have their own characteristics, they are widely used in the plastic industry.

in order to meet the needs of different uses, chemical or physical methods are used to change some properties of plastic products to achieve the intended purpose, which is plastic modification.

Q1.The length is larger than the normal pelletA: Cause of occurrence:The main reasons are: starting the machine, pulling or breaking the strip, the direction of the strip is not straight, the strip is not properly soaked in water, and the cutting tool of the granulator is worn or has gaps.Main solut
