UNDERWATER PELLETIZING SYSTEM MARKET REPORT OVERVIEW

The global underwater pelletizing system market size was USD 0.14 billion in 2024 and is expected to touch USD 0.21 billion by 2033, exhibiting a CAGR of 3.7% during the forecast period. Asia-Pacific is dominating the underwater pelletizing system market share in 2025.

An underwater pelletizing system involves melting the polymer in molten form, then squeezing it into the water-filled cutting chamber, then pelletizing, conveying, and dewatering it to become pellets. There is no better cutting system for all thermoplastics than the underwater pelletizer. Pellets that are submerged in water are cut by underwater pelletizing system. The system produces superior spherical pellets and is more versatile, especially when working with sticky polymers. A centrifugal dryer then treats the pellets as slurry.

Using an underwater pelletizer cutting system, the relative spatial relationship between the blades of an extrusion die can be adjusted finely. A carriage drives a motor which drives the cutting assembly, which may be self-aligning. A servomotor drives a ball screw to move the carriage relative to a fixed frame. A shaft is attached to the carriage at one end of the ball screw, which should have zero backlash. It is possible to provide a PLC control system for receiving operator input and running a cutting program, providing appropriate signals to the servomotor to advance the cutting assembly as the cutting assembly's blades wear out. An extrusion die can be measured by a measuring system connected to the PLC system to measure the contact pressure.

COVID-19 IMPACT

"Halt on Machinery and Equipment to Hamper Market"

A global economic slowdown has been caused by the COVID-19 outbreak, affecting various sectors. Consequently, the underwater pelletizing system market, a sector with such broad economic ties is expected to be affected both initially and over time by COVID-19. Even the petroleum, and petrochemical industry, which uses the underwater pelletizing system have had a huge impact during the time of pandemic. There are many checkpoints in the country where essential supplies for the C&PC sector are held up, according to the Indian Chemical Council (ICC). It was difficult for the employees to reach their workplaces, even though the manufacturers had operated. Employee safety has been a primary concern for the majority of the companies in the underwater pelletizing system supply chain. The petrochemical industry, pharma and food, and other critical industries are operating at half capacity. The ease of lockdown favored the market and the same is expected for the growth of the market.

LATEST TRENDS

"Extensive Usage of Underwater Pelletizers in Coal Industry to Drive the Market Growth"

Underwater pelletizing of coal fines provides excellent coal recovery and produces a low-ash, low-moisture product. In order for agglomeration to occur, several factors must be taken into account, such as the rank of the coal, the type of oil added, and the amount of oil used.

DRIVING FACTORS

"External Appearance Quality of Underwater Pelletizing System to Drive the Market Growth"

By scraping off the plastic in the melt state and allowing the pellets to solidify after cooling by circulating water, pellets under the melt form no dust, and are uniform in size and shape. The pellets are more convenient to package, transport, and pack after they have been processed by the underwater pelletizing system. Traditional pelletizing involves extruding the polymer melt from the tape injection plate, cooling and solidifying it in a water spray cooling tank, and then cutting it in the pelletizer. As a result of this traditional pelletizing method, chips and dust will be produced. Aside from being uneven, pelletizing will also cause secondary pollution.

"Distinctive System Characteristics of Underwater Pelletizers to Drive the Market Growth"

The molten plastic is cut directly into pellets and removed by the cooling water after it exits the die hole. Controlling the temperature and flow rate of the circulating water can control the crystallinity of the pellets, thereby ensuring stable quality. The underwater pelletizer produces pellets with a high level of transparency and gloss, and the process of solid plastic pelletizing is affected by the high crystallinity of the plastic as a result of the delay in cooling, which affects the performance. Due to the fact that pelletizing is carried out underwater, oxidation of the product in the air is minimized. The system has a shortcoming as well. In order to prevent color mixing and unevenness caused by static electricity, the pellets must be dispersed before mixing the toner, because they are round particles.

RESTRAINING FACTOR

Physical blockages of the die holes from contaminants in the material or poorly dispersed mineral fillers can result in pellets that are not consistent. Most of the time, it is desirable to have a screen changer or some kind of filtration before the die. Using a special hand-cleaning tool, this type of blockage can be removed from smaller systems. It is usually necessary to remove the die for cleaning on larger systems. Long periods of idle time should also result in reduced temperature profiles, including the die heat zone.
