The Exhibition Hall Of COLOWE's Second Factory Has Officially Opened: Redefining Cost-effective Plastic Extruders With Verifiable Hard Power
1, Industry background: Why high cost-effective extruders have become the new focus of global plastic processing
According to the United Nations Environment Programme's Global Plastic Outlook 2025, the annual global plastic production has exceeded 430 million tons, but the recycling rate is still below 10%. The EU's Packaging and Packaging Waste Regulations (PPWR) and mandatory targets for recycled content in multiple countries are driving a large number of enterprises to shift from raw material processing to recycled modified, bio based materials, and controllable degradation formulas. According to statistics from the China Plastics Machinery Industry Association, the export of plastic extruders in China will maintain double-digit growth in 2024, with a particularly significant increase in demand for co rotating twin-screw extruders used for blending modification.
What customers want is not just the ability to squeeze materials, but lower unit energy consumption, more stable process windows, and faster formula switching capabilities. This is precisely the question that the exhibition hall of COLOWE's second factory hopes to answer on site.
2, Hard power of the exhibition hall in the second factory of COLOWE: three verifiable data
1. 12000 square meters of manufacturing and process validation space
The new exhibition hall is linked with the manufacturing workshop, allowing customers to view the entire process of the co rotating twin-screw extruder from cylinder processing, screw component detection to complete machine assembly on the same moving line, and directly enter the experimental area for material testing. Real time visualization of process parameters, energy consumption curves, temperature control fluctuations, and other data helps customers who are new to plastic extruders establish a clear understanding.
2. Annual production capacity of 300+sets and standard delivery cycle of 45 days
Standardized component platform and modular design enable cost-effective extruders to no longer rely on a large number of non-standard customizations. For customers who are trying new materials for the first time, COLOWE can provide a smooth amplification path from experimental twin-screw extruders to mass production plastic extruders, reducing the risk of process deviation during the amplification process.
3. 99.2% one-time delivery qualification rate
According to the internal quality management system data, the first power on acceptance rate of delivered equipment from 2024 to 2025 is 99.2%, and the average fault response time is controlled within 24 hours. This data does not constitute a commitment, but it can demonstrate manufacturing consistency and pre factory validation level.
3, Same direction twin-screw extruder: why it is more suitable for environmental modification and new material development
The core advantage of the co rotating twin-screw extruder lies in the combination of modular screws and kneading blocks, which can achieve stronger dispersion and distribution mixing. Combined with units such as vacuum devolatilization, side feeding, and weight loss metering, the process window is wider when processing high filling, high fiber, recycled materials, and thermosensitive materials.
The key display of this type of equipment in the exhibition hall of the second factory building by COLOWE is: length to diameter ratio L/D covering 28-64, screw speed up to 900 rpm, torque level covering 1.5-15 N · m/cm ³, supporting small-scale and large-scale testing of PLA/PBAT modification, rPET/rPP regeneration reinforcement, and high-temperature engineering plastics. For customers who are new to plastic extruders, these parameters do not need to be fully understood, but the differences in specific energy consumption of the same formula under different screw configurations can be seen on site, thus understanding that the "cost-effectiveness" of high cost-effective extruders comes from process matching, rather than simple price concessions.
4, High cost-effectiveness extruder does not equal low price: full lifecycle cost is the key
Many international customers tend to focus their budget on the total equipment price when purchasing plastic extruders for the first time. However, the industry white paper "Life Cycle Cost Assessment of Plastic Mixing Equipment" points out that the procurement cost of extruders usually only accounts for 15% -25% of the total 5-year ownership cost, with energy consumption, screw barrel wear, downtime maintenance, and process waste being the main components.
COLOWE's response is to define high cost performance extruders as low specific energy consumption, long-life core components, quick replacement of screw components, and remote process support. The exhibition hall of the second factory building is equipped with wear-resistant cylinder profiles, screw component life comparisons, and real-time energy consumption panels, allowing customers to understand with data why configurations with slightly higher initial prices can actually recover the difference within 12-18 months through energy conservation and reduced downtime. This is the fundamental difference between "high cost-effectiveness" and simply low prices.
5, The five most common questions asked by first-time customers
1. We only have laboratory formulas and no experience in mass production. Can we directly use a co rotating twin-screw extruder?
Okay. COLOWE suggests starting with a small-sized experimental co rotating twin-screw extruder, first verifying the process window and batch stability, and then scaling up to mass production models with the same screw configuration. The experimental line in the exhibition hall of the second factory supports customers to bring their own materials for on-site testing.
2. Will the opportunity for high cost-effectiveness extrusion not sacrifice the quality of key components?
No. COLOWE adopts standardized and modular design on key components such as gearboxes, cylinders, and screw components, reducing costs through bulk procurement and process optimization, rather than lowering material grades. The material reports and heat treatment curves of key components can be viewed in the exhibition hall.
3. How to deal with environmentally friendly modified materials that are prone to degradation or produce volatile matter?
The co rotating twin-screw extruder can be equipped with multi-stage vacuum devolatilization ports and low shear temperature rise screws, combined with closed-loop temperature control, to reduce the degradation of heat sensitive materials. On site reference process packages can be provided for materials such as PLA, PBAT, rPET, etc.
How to ensure overseas after-sales service?
COLOWE provides remote diagnosis, video debugging, and critical spare parts safety stock recommendations. The device control system supports data uploading and remote parameter reading, making it easy to quickly locate problems.
How long does it take from placing the order to delivery?
The standard delivery cycle for conventional high cost-effective extruders is about 45 days, while the customized blending and modification production line depends on the configuration. The modular platform in the exhibition hall of the second factory building can shorten the communication and design cycle.
6, Conclusion: Equipment is no longer a cost, but a profit entry point for green manufacturing
As the global plastic industry enters a stage where energy consumption is calculated per kilowatt hour and yield is amplified per one percent, the selection of co rotating twin-screw extruders, cost-effective extruders, and plastic extruders is determining whether a factory can continue to operate under new environmental and cost constraints. The official opening of the exhibition hall of the second factory of Nanjing Kelongwell Chemical Machinery Co., Ltd. provides a window for communication that does not rely on language, but only relies on data and on-site verification.
Welcome international customers who are trying to produce new materials, hoping to increase regeneration content, or looking for cost-effective extruder solutions to come to the site with raw materials and problems. Watching a real run is more valuable than reading ten samples.
