Consistent maintenance of a plastic pelletizing machine is critical for ensuring high-quality output and preventing costly downtime in the recycling industry. This comprehensive guide by Nanjing Haisi Extrusion outlines the five essential pillars of extruder care: daily operational checks, periodic system overhauls, wear-part management (such as screws and cutters), safety protocols, and thermal process optimization. By adhering to these standard operating procedures, manufacturers can maximize the lifespan of their granulation lines while consistently producing premium, defect-free recycled plastic pellets.

Material overflow at the exhaust port during the TPE pelletizing process can impact production efficiency and product quality. The main causes include improper equipment configuration, inadequate temperature control, and poor filter management. To prevent overflow, manufacturers should ensure the feeding speed matches the main extruder speed, adjust the screw-barrel clearance, and install reverse conveying elements. Temperature should be precisely controlled to avoid incomplete plasticization or excessive material fluidity. Regularly replacing or cleaning filters and selecting appropriate filter apertures can also help prevent clogging and overflow. Implementing these measures ensures stable production and high-quality TPE pellets.

As an environmentally friendly mechanical production equipment, plastic pelletizers produce useful granular plastics, but for these plastic production machinery and equipment, necessary maintenance is still required, especially in daily life. Some maintenance before and after production can maintain the normal operation of the equipment and extend its service life, which is also very good for users.

Happy Chinese New Year!

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

The blending toughening of polypropylene PP is widely used in various fields due to its significant effects, low industrial investment, and fast and easy implementation. Blending toughening modification refers to the use of other plastics, elastomers, and inorganic powders as modifiers to blend with PP to improve the toughness of PP plastics.

The current automotive sealing strip materials mainly include four types: PVC sealing strip, EPDM sealing strip, TPV sealing strip, and TPE sealing strip. Below, we will analyze the advantages and disadvantages of these four automotive sealing strip materials.

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
