New Year And New Outlook, Cologne Will's New Factory Helps You Reach The Peak Again: How Customized And Efficient Extruders Reshape The Cost Performance Benchmark Of Plastic Granulation
At the beginning of the new year, the global plastic industry is standing at the starting point of a new cycle. With the dual baptism of capacity restructuring and environmental regulations in the global plastic pellet market by 2025, plastic pellet manufacturers not only face the pressure of fluctuating raw material costs, but also encounter "stringent" requirements for material performance from downstream product companies. At this juncture of both opportunities and challenges, the new factory of Nanjing Kelongwell Chemical Machinery Co., Ltd. has been fully put into operation, committed to providing a cornerstone for every granulation entrepreneur who pursues excellence through technological upgrading and cost optimization.
Introduction: New Year's Breakthrough Question - Is Your Extruder Really "Suitable" for the Future?
In 2025, it is not only a change of time, but also the manifestation of a technological watershed. At the Chinaplas 2025 and K 2025 exhibitions, industry giants are pointing towards "green, intelligent, and responsible", reflecting the transformation of plastic processing from "general manufacturing" to "precision manufacturing".
Faced with new formulation challenges such as high calcium carbonate filling, biodegradable material modification, or high-performance masterbatch, many manufacturers have found that universal plastic extruders are no longer able to balance the contradiction between "high yield" and "quality".
The completion of the new COLOWE factory in Nanjing is precisely to address this core pain point. We not only manufacture equipment, but also help you achieve a perfect balance between "quality" and "cost" in the market competition of 2026 through deep customization of co rotating twin screw extruders.
1. Cracking the production capacity myth: why is "energy" more important than "speed"?
In the field of plastic extrusion granulation, many customers who are new to high-efficiency extruders often fall into the misconception of only looking at the screw speed. According to the classic research on twin screw extruder amplification by Dow Chemical's R&D team, Specific Mechanical Energy (SME) is the core key that determines the final particle quality and production capacity ramp up.
1.1. Data Insights: Two Deterministic Trends in the Granulation Market in 2026
According to Bezos Consulting's analysis of the global plastic pellet market, by 2030, the global market size will continue to expand, but the core of competition has shifted from simply "tonnage" to "added value". This means:
a. High filling and functionalization have become mainstream: In order to reduce costs, the proportion of high filling (calcium carbonate, talc powder) in PP and PE continues to increase, which puts strict requirements on the torque and dispersibility of twin screw extruders.
b. Environmental regulations force process upgrades: the removal efficiency of volatile organic compounds directly determines the application level of recycled or modified materials.
1.2. COLOWE's solution:
The KLWE series co rotating twin screw extruder that our new factory has put into operation has introduced an amplification design logic based on torque level and specific energy (SME) from the beginning of the design. As research has shown, only by accurately matching the specific energy input from the laboratory to the mass production stage (maintaining an ideal range of 0.079-0.086 kWh/kg) can process accidents such as "solid phase unmelted" or "over degradation" be avoided, ensuring that the density and uniformity of particles do not decrease at all while increasing production capacity.
2. New Factory · New Dimension: Redefining the Two Main Supports of "Cost Performance"
For those who pursue high cost-effectiveness, the new COLOWE factory not only brings an increase in production capacity, but also a deep reconstruction of the concept of "cost-effectiveness": cost-effectiveness=(output value x stability)/(procurement cost x energy consumption).
2.1. Quality support: Process adaptation from "usable" to "refined"
Recently, a well-known modification enterprise used our plastic extruder for PP material testing. With a precise temperature control system and high torque engagement block design, not only was the one-time testing successful, but also in the subsequent challenge of higher filling ratio formulas, our technical team achieved a significant increase in production capacity through precise optimization of screw combination.
·Professional deep digging: We provide customized screw geometry shapes for different material systems, such as high glass fiber reinforcement, high filling masterbatch, and thermosensitive degradable plastics. The kneading block arrangement of the COLOWE co rotating twin screw extruder can accurately control the shear stress that the material is subjected to, ensuring that the pigment and filler are evenly dispersed at the micro level without "white spots" defects.
2.2. Cost advantage: Optimization of ton power consumption throughout the entire lifecycle
In the current era where energy consumption has become a "hidden profit killer" for enterprises, the new COLOWE factory has improved the meshing accuracy by introducing more advanced machining centers, resulting in a significant increase in the mechanical efficiency of high-efficiency extruders.
·Data evidence: Referring to cutting-edge industry technology, adopting permanent magnet direct drive technology and optimized meshing principle can effectively reduce ineffective friction heat generation. By finely designing the temperature control system of the screw core, COLOWE ensures that thermosensitive materials maintain stable performance during low-temperature extrusion, with significantly optimized comprehensive energy consumption compared to traditional designs, directly reducing the processing power consumption per ton of material.
3. Key question answer: The three most concerning issues for you in granulation customization
Q1: I want to try making new materials, such as POE elastomers or PLA biodegradable materials. Can the standard machines from COLOWE adapt?
A: It depends on 'flexibility'. The COLOWE co rotating twin screw extruder adopts a modular principle. The barrel and screw components produced by the new factory have stronger universality. For POE volatilization or PLA thermal control, we can address it by adjusting the aspect ratio (L/D ratio) and the number of exhaust ports. For example, for materials with high solvent content, our screw combination can cover multiple modes from flash evaporation to surface renewal, ensuring effective removal of 5% -85% solvent content.
Q2: As a customer who is new to international business, can your equipment meet the strict VOC standards for plastic products in Europe and America?
A: Absolutely possible. VOC (volatile organic compound) residue is a roadblock to entering the international high-end market. Our solution is to utilize the powerful stripping ability of efficient extruders. By setting up multi-stage exhaust or lateral stripping on the twin screw extruder, combined with special anti threaded sealing elements, small molecule residues in the melt can be reduced to extremely low levels. This is precisely the key to COLOWE helping customers benchmark their products against world-class quality.
Q3: How to obtain the optimal procurement cost while ensuring quality in the face of competition in the Middle East or Southeast Asian markets?
A: This is the manifestation of the scale effect of the new COLOWE factory. We have reduced unnecessary design costs through localized research and modular production. As demonstrated in our Middle Eastern customer case, we optimized the screw design for PP high filling systems to solve the problems of "uneven dispersion" and "easy breakage of the pull strip". This not only ensures the smoothness of the particles, but also reduces the customer's later labor costs through highly automated production lines, achieving a "double reduction" in equipment procurement and operating costs.
4. Moving towards the future: How customization can help you "reach new heights"
Climbers are never afraid of heights, they only worry about whether the road under their feet is solid. For plastic pellet manufacturers, choosing a suitable plastic extruder production line is choosing the path of enterprise development.
The new Nanjing Kelongwell factory has not only expanded its production capacity, but more importantly, established a process database. We will feed back the data of each customized case (whether it is high filling PP or engineering plastic reinforcement) into the design of the new machine.
·Core value: What we deliver is no longer a cold and efficient extruder, but a set of "formula carriers" based on data, validated in practice, and optimized for the future. It ensures that your small-scale experiments in the laboratory are successful and can be scaled up to 24-hour continuous mass production without reservation, avoiding the risk of process amplification.
Conclusion
The horn of 2026 has sounded, and the competition in the plastic granulation industry will be a comprehensive contest of technological adaptability and cost control.
