COLOWE Camphor Wood Head Plastic Expo Successfully Concluded: Why Did A Settled Account Co Rotating Twin-screw Extruder Make International Buyers Stop For The First Time
1, Closing scene: The most questioned topic is not the price, but the "ton power consumption curve"
During the Plastic Expo, a considerable proportion of the international customers received at the COLOWE booth had their first systematic contact with the selection of plastic extruders. Their common feature is that they have a clear direction for environmentally friendly materials (rPET, PLA/PBAT, PE/PP high filling regeneration), but lack quantitative judgment on the energy consumption structure of co rotating twin-screw extruders. The on-site technical team did not start with the arrangement of screw components, but first opened the operating data of a 65D model: the specific energy consumption of PS granulation falls within the range of 0.25-0.29 kWh/kg, which is about 17% energy-saving compared to conventional PS granulation lines; The ton power consumption of PP+40% calcium carbonate filling granulation is also compressed to 0.25 kWh/kg, which is 15% -20% lower than the common level in the industry. The reason why these numbers are persuasive at the exhibition is that they have reduced the slogan of "high cost-effectiveness extruder" to a verifiable energy consumption curve.
2, Data evidence: Why "power saving" has changed from a bonus point to an admission ticket
The sensitivity of international buyers to energy consumption does not come from persuasion from equipment manufacturers, but from the dual pressure of regulations and market structure. According to the GEP Research 2025 industry report, the penetration rate of high-efficiency and energy-saving extruders has increased from 35% in 2024 to 48% in 2026. During the same period, China's new energy consumption quota standards raised the energy efficiency threshold for extruders by 22%. In other words, a plastic extruder that does not meet energy consumption standards has lost its eligibility to participate in supplier screening in many target markets. At the same time, Mordor Intelligence's market calculations show that the global plastic extruder market size will be approximately $8.42 billion in 2026 and will increase to $11.33 billion by 2031, with a compound annual growth rate of 6.12%. The increase is mainly concentrated in twin recycle blending and recycling scenarios. The EU's Packaging and Packaging Waste Regulation (PPWR) imposes mandatory requirements for recycled content from 2030 to 2040, which locks in the irreplaceability of co rotating twin-screw extruders in the blending of recycled materials from the demand side. A set of control data repeatedly mentioned at the COLOWE booth is that after the new factory cluster assembly line is put into operation, the stability of single machine output of standard models in LDPE and HDPE processing is increased by 25%, and the unit energy consumption is reduced by about 30% compared to traditional equipment. For first-time buyers, the significance of this set of numbers lies not in the "good parameters", but in pulling the full lifecycle cost of the equipment back from the vague "to be discussed later" calculation table before signing the contract.
3, Technology implementation: 'Being able to test new materials' is more important than' having a beautiful parameter table '
A noteworthy detail at the Plastic Expo site is that many international buyers bring not mature formulas, but new material solutions in the laboratory stage - biodegradable modification, high proportion recycled material compounding, and mineral filling substitution. The core test of this type of demand for co rotating twin-screw extruders focuses on the flexible switching ability of specific torque, aspect ratio, and screw configuration. The COLOWE 65mm co rotating twin-screw extruder production line adopts a high torque gearbox with a length to diameter ratio of 48:1, a maximum screw speed of 900 rpm, and a specific torque of 11.3 N · m/cm ³. Combined with modular kneading block switching, the process window can be reconfigured in a relatively short time. The parallel layout of the H-series high torque platform and the D-series high diameter ratio platform allows first-time customers to not have to choose between "high torque" and "high output", but to find matching intervals based on their own material routes. The design of the stair free barrel eliminates the dead corners of material retention structurally and reduces the physical causes of black spots. This is an engineering improvement that is closer to actual yield than peak production for international orders with high recycled material content and extremely low tolerance for impurities and color spots.
4, The four most concerning questions for first-time users about the COLOWE plastic extruder
Q: How should I distinguish between a co rotating twin-screw extruder and a single screw equipment when I am doing plastic modification or recycling granulation for the first time?
If the product route involves multiple sets of distribution mixing, inorganic filling, compatibility adjustment of recycled materials, or narrow processing windows of biodegradable materials, the dispersion mixing ability and self-cleaning characteristics of co rotating twin-screw extruders are usually unavoidable options. The judgment given by Kelongwell at the Plastics Expo is based on the product of energy consumption and formula flexibility, rather than the price of a single model. In the first half of 2026, the export orders of cost-effective extruders from Cologne Weir increased by 41% year-on-year. Among the 7 twin-screw extruder production lines delivered to customers in Europe, Southeast Asia, and the Middle East during the same period, 5 were cost-effective co directional twin-screw extruders used for rPET thickening, PLA/PBAT modification, and PE/PP high filling regeneration granulation. These delivery scenarios highly overlap with the target market for first-time users, meaning that the equipment selection logic has been repeatedly validated in similar operating conditions.
Q: Does a high cost performance extruder mean subtraction in torque or control system?
On the contrary. COLOWE's definition of a cost-effective extruder refers to the "total cost per unit output" rather than the "purchase price". The difference between the ton power consumption achieved by the 65D model in PP+40% calcium carbonate filling granulation and the industry's advanced energy consumption benchmark has been deliberately compressed to a sufficiently friendly range for first-time buyers, while retaining the process redundancy supported by a specific torque of 11.3 N · m/cm ³ and a maximum speed of 900 rpm. For customers who are trying to produce new materials, this means that the equipment will not frequently touch the capacity boundary due to parameter fluctuations during the pilot stage of the formula, thereby reducing the secondary investment of "changing the formula requires changing the equipment".
Q: What are the specific impacts of environmental compliance trends on the selection of plastic extruders?
The impact is concentrated on the stability of recycled material mixing and emission control. The mandatory target for the regeneration content of EU PPWR is driving the transformation of the entire production line towards the direction of upgrading the precision of twin-screw hunger feeding and melt filtration. The continuous filtration scheme of the dual plunger screen changer adopted by Kelongwell on the co rotating twin-screw extruder, as well as the modular cylinder's ability to adjust the shear strength and mixing strength in different zones, directly correspond to the maintenance of product quality stability under the fluctuation of recycled material batches, rather than the "green label" on the conceptual layer.
Q: How to verify if a device is truly "accounted for" during the initial purchase?
Require suppliers to provide actual energy consumption data of the target material on similar models, rather than theoretical peak values on the sample. The actual test data of standard models after the new COLOWE factory is put into operation - the unit energy consumption of LDPE/HDPE processing is reduced by about 30%, and the output stability is improved by 25% - can be used as a starting point for horizontal comparison. However, a more effective approach is to send the material samples planned for processing to the experimental stage and run the SEI (Specific Energy Input) curve of the own formula on the modular screw combination. After the end of the Plastics Expo, COLOWE continued the pace of technical docking during the exhibition period, transferring the unfinished formula samples on site to the factory experimental unit, which was also one of its first ways of serving customers.
5, After the end: Three days at Zhangmutou, answering a question with a longer cycle
The three-day extension of the Zhangmutou Plastic Expo is brief, but it puts a problem in front of international buyers who pursue environmental protection and high cost-effectiveness: in the cycle of mandatory targets for recycling content and tightening of energy efficiency thresholds, the value of a plastic extruder is no longer defined solely by the power on the nameplate or the number on the quotation, but by the specific energy consumption, process window width, and continuous operation stability it runs on the target material. The closing ceremony of COLOWE at this exhibition is essentially an alignment of selection language - pushing the discussion of co rotating twin-screw extruders from "expensive or not" to the level of "how much electricity is spent per kilogram of particles and whether the equipment can keep up when changing formulas". For international customers who are entering the Plastic Expo exhibition hall for the first time and are looking for a low threshold but not low standard path for plastic extruders, this alignment itself is more worth bringing back than the parameters of any isolated equipment.
