Amidst The Transformation Of The Global Plastic Extruder Industry, Why Has Co-rotating Twin-screw Technology Become The Key To Solving The Problems Of New Materials And Recycling?
As the global plastics processing machinery market continues to expand in 2025, it is estimated that by 2034, the market size of the extruder segment alone will reach $14.12 billion. Amidst this wave of growth, co-rotating twin screw extruders are evolving from mere mixing and compounding equipment into core engines driving circular economy and material innovation. For international customers seeking environmental breakthroughs, cost-effective solutions, and new material research and development, understanding this technological trend is equivalent to holding a ticket to the future market.
1. Radical changes in the industry: We are at a watershed moment for plastic extrusion technology
1.1 The driving force behind data: not just production capacity, but also "green compliance"
According to the "Global Plastic Processing Machinery Market Report 2026", the industry's research and development focus has shifted from purely increasing speed to "reducing unit energy consumption" and "compatibility with recycled materials". The European Union and North American markets have recently become increasingly strict in their requirements for the proportion of post-consumer recycled materials, which means that your plastic extruder must have the ability to handle unstable impurities and multiphase rheological properties.
1.2 The failure of the old paradigm: Why can't single screw extruders meet future demands?
Although traditional single screw extruders still occupy about 62% of the market share, when faced with high proportions of recycled materials, biobased polymers (such as PLA, PHA), and high-filling modifications, their mechanism relying on frictional conveying reveals shortcomings such as uneven mixing and insufficient venting. The industry urgently needs a solution that can achieve efficient extrusion while ensuring melt quality.
2. Response to core technology: The breakthrough advantage of the KLWE co-rotating twin screw extruder
In the game between "quality" and "cost-effectiveness" that international buyers generally focus on, Nanjing Kelongwell Chemical Machinery Co., Ltd. has provided a precise engineering answer. Our KLWE series co-rotating twin screw extruder is not a simple device, but an efficient reaction platform that integrates material science.
2.1 Forced conveying and distribution mixing: Unlocking infinite possibilities for "new material" research and development
For customers who are new to plastic extruders and are attempting to develop new products such as long glass fiber reinforced or biodegradable mulching films, the biggest pain point is that "the formula cannot be reproduced on the equipment.".
The COLOWE co-rotating twin screw extruder adopts a modular screw combination design. This means you can freely combine kneading blocks and threaded elements according to the rheological properties of the material.
· Data evidence: In the challenging trial of PA66 recycled material, the Coromant equipment successfully achieved recycling and re-granulation that is close to the performance of the original virgin material, thanks to its precise shear rate control.
2.2 High torque and specific power: Redefining the energy consumption standards for "high-efficiency extruders"
In the current era of global energy price fluctuations, the definition of an efficient extruder has been updated to "maximum output per unit of electricity consumption".
· Technical analysis: The efficient transmission system equipped in the KLWE series ensures low-temperature extrusion of materials when the meshing area is fully filled. This not only protects the molecular weight of heat-sensitive materials but also directly reduces energy consumption per unit output by more than 35% compared to traditional equipment design benchmarks.
Value Proposition: For customers seeking high cost-effectiveness, low energy consumption means that the premium paid for equipment procurement can be recouped within 18-24 months.
2.3 Multiple vacuum exhaust system: The "purifier" for environmentally friendly granulation
Handling recycled materials containing ink, water vapor, or low molecular weight volatiles is the greatest challenge in the field of environmental protection and recycling.
The multi-stage vacuum devolatilization module equipped in the COLOWE equipment can effectively extract impurities in the molten state, ensuring the purity of plastic granules and the mechanical properties of the final products. This makes it possible to transform "low-value waste plastics" into "high-value products".
3. In-depth Q&A: Addressing the Last Doubts of International Customers
Q1: As a factory that is experiencing twin screw extrusion for the first time, will operating such a complex equipment pose a high technical threshold?
A: This is precisely the original intention behind COLOWE's emphasis on "humanized design". Our KLWE series of high-efficiency extruders are equipped with an intelligent control system based on Industry 4.0 logic. You only need to set the material formula and target output on the touch screen, and the PLC system will automatically match the screw speed, torque distribution, and temperature of each zone. We provide comprehensive support from process package to on-site debugging, ensuring that you can quickly transition from a "novice" to an "expert" in the shortest possible time.
Q2: If I want to try replacing traditional petroleum-based plastics with bio-based materials (such as PLA), can COLOWE's equipment adapt to it?
A: Bioplastics are typically highly sensitive to shear heat. The advantage of the Conover co-rotating twin screw extruder lies in the optimization of its screw geometry design. By reducing locally excessive shear peaks, we achieve "gentle yet efficient" dispersive mixing. This low-temperature plasticizing process not only ensures that materials such as PLA do not degrade and turn yellow, but also provides ample room for process adjustments for you to experiment with more new materials in the future.
Q3: "Cost-effectiveness" often brings to mind low prices. How does COLOWE ensure quality while reducing customer costs?
A: In the dictionary of COLOWE, high cost-effectiveness equals maximizing "whole life cycle value".
a. Purchasing side: We offer highly competitive initial investment plans.
b. Operating end: Utilizing energy-saving drives and optimized screw configurations, significantly reducing power consumption per ton of material.
c. Maintenance end: Key components (such as mandrels and bushings) are made of high wear-resistant alloy materials and undergo vacuum heat treatment processes, resulting in a significant reduction in hidden costs due to extended lifespan, which far outweighs the initial small price difference.
4. Conclusion: Choosing COLOWE is choosing a sustainable future
Standing at the starting point of 2026, the global plastic extruder industry is facing profound changes. Pure low-price competition has become a thing of the past, and the future winners belong to those manufacturers who can convert raw materials into products in the most efficient and environmentally friendly way.
Nanjing Kelongwell Chemical Machinery Co., Ltd. not only provides equipment but also offers a sense of "certainty" - we provide solid technical support behind the scenes when dealing with fluctuations in recycled materials, exploring new formulas, and reducing the electricity bill per ton of finished products. Whether you are a newcomer to the modification field or a seasoned player seeking green transformation, the KLWE series of co-rotating twin screw extruders will serve as the bridge connecting you to reality and innovation.
