As an important equipment in the development of modern polymer materials, twin screw extruder is widely used in compounding, extruding, pelletizing and molding of plastic polymer materials. When referring to the twin-screw extruder, one will naturally think of the industry's leading company-Nanjing Keya Equipment Group.
“It has been innovating and has never been surpassed”. Keya has developed and produced world-class twin-screw extrusion equipment. After 25 years of development, Keya has stepped out and embraced the world, not only continuing domestic twin-screw extrusion technology. The development of the industry also ranks internationally.
New product launch: SK40 Plus and SK70 Plus twin screw extruder
At the site of the 2019 Chinaplas, Plastic Machinery Network (siamtlr.com) invited Mr. Liu Guangzhi, the founder and chairman of Keya Equipment Group, to participate in an on-site interview. During the exchange with Liu Dong, we further understood To the extraordinaryness of Keya twin-screw technology and proud of the development of domestic twin-screw technology.
CHINAPLAS 2019 Site Interview: Right is Keya Liu Dong
At the Chinaplas 2019, Keya showcased two new products-SK40 Plus and SK70 Plus twin-screw extruders, which aroused widespread concern in the industry. Liu Dong said frankly that this exhibition is also intended to convey such a message to the industry that the Chinese (Keya) has the ability to make the world's best twin-screw extruder.
These two new models use Kaya's new technology, which is energy-saving and features. Both the core components and the design concept are not inferior to well-known foreign manufacturers. During the live interview, Liu Dong introduced to reporters the main technical highlights of the two new devices in detail:
These two new products belong to the SK Plus series with torque levels up to 15 and performance comparable to German ZSK models. This series of products are high-level domestically in terms of design, manufacturing and assembly, and make full use of mature foreign technology to ensure the overall accuracy and stability of the equipment. The screw groove depth ratio of 1.55 or 1.8 can be selected to meet customer requirements. Different needs for equipment. Dong Liu also said that the customer's requirements for wear and corrosion resistance of equipment are constantly increasing. As a professional twin screw manufacturer, in addition to the processing section of optional imported wear-resistant and corrosion-resistant materials for customers, Keya has also developed a new type of The screw and barrel are wear-resistant and corrosion-resistant, and are manufactured by Keyar independently.

With this technology, Keya not only can compete with the international advanced level, but also has its own unique technical characteristics. Later, Liu Dong stood up and introduced the sample of the cylinder on the stand to the reporter: "This is an abrasion-resistant and high-strength alloy layer developed by Keya. It is sintered in the figure-eight hole of the cylinder, and the figure-eight hole is refined Grinded. This process has been applied for invention, which is owned by Veikea all over the world. Compared with the traditional barrel manufacturing process, it replaces the expensive alloy bushing on the one hand, and optimizes the processing process on the other hand. Reduced man-hours, greatly improved product quality and processing efficiency. In addition, according to the customer's actual requirements of different materials wear and corrosion resistance of the barrel, the alloy material formula of the sintered layer can be flexibly adjusted to achieve good application results. "
Dong Liu introduced to reporters the spray technology of screw elements
In addition, another highlight of the new product at this exhibition is the screw component spraying technology. This technology sprays a uniform, super-hard layer of 0.02-0.04? M on the surface of the screw component without affecting the accuracy of the component. Thin film coating, although this coating is thin, but the surface density is very high, and has a high surface finish, which can greatly improve the wear resistance of the screw.

During the exhibition, Keya's new products and technologies fully demonstrated its strong strength in the industry, especially the SK Plus series. Most of the core components' innovative technologies can be described in China. In particular, the new heating rod technology of the barrel, the application of water-cooled motors, and the control system of the k-cloud extruder are all in the domestic position. The technological progress in the cooling channel of the barrel and the flow channel of the head has also reached. World-class standards have fulfilled the desire of Keya to be able to manufacture equipment reaching international advanced levels.
Liu Dong believes that the core of an enterprise's survival and development is its technology research and development capabilities. For 25 years, Keya has continuously invested in product technology innovation and research and development. The company takes “doing good twin-screw extruders in China” as its mission and implements the enterprise development policy of “strengthening” and then “bigness”. Liu Dong said: "Keya promotes the development of the entire industry by continuously improving its technology development capabilities and realizing the continuous expansion of product technology and twin screw extruder applications."
Embrace the Internet: June trial run of intelligent management system
After 25 years, the twin-screw extruder has developed to the third generation (the key technical indicators are marked by the screw speed reaching 900 rpm). Its overall performance and stability have been greatly improved compared with the previous two generations. The launch of the SK Plus series models has greatly improved the performance index of domestic twin-screw extruders, which not only requires excellence in product research and development design, processing manufacturing, inspection and assembly, but also supports soft power. In the era of the rapid development of the Internet and information technology, the application of information technology is still a model for the industry.
In the manufacturing and manufacturing management link, Keyar uses advanced information technology and Internet technology to achieve intelligent management of production operations. Through data collection, collation and analysis of product design, production site and other links, it can effectively improve product quality. The intelligent management system will be put into trial operation in June.
In terms of customer product requirements, Keyar launched the k-cloud intelligent control system in the industry, which provides functions such as automatic control, data acquisition, data storage, data analysis, production management, pre-maintenance, and integration of management and control to achieve a complete set of extruders. Digitalization and visualization of production line management and processes. Liu Dong believes that using the Internet to make industrial products will reduce communication costs and improve the efficiency of problem handling. It will be of great benefit to maintain and ensure the normal operation of the client group. Internet technology should be used to fully utilize it. Apply to enterprise management and product innovation to provide customers with more products and services.
Eternal goal: to make China and the world a better twin screw

According to the reporter, most of the twin-screw extruder products currently sold in the domestic market are mainly small and medium-sized models with screw diameters below 100mm. Keya has considerable experience in designing and manufacturing medium and large models with screw diameters of 125cm, 130cm, 145cm and even larger sizes. In the early 1990s, it undertook many medium and large-scale production lines of domestic companies such as Sinopec and accumulated rich design, Manufacturing, installation and debugging experience. In recent years, it has occupied an advantage in the medium and large equipment market. In 2018 alone, it completed the sales of nearly 40 sets of medium and large model production lines and delivered 30 sets of users, which has caused a lot of sensation in the industry.
Through this exclusive interview, we have full confidence in the development of domestic twin screw technology by knowing Keya. As Liu Dong said, "With the improvement of manufacturing level and design level, China's twin-screw extruder will one day replace the medium and large-sized twin-screw extruder imported from abroad." It is precisely because of the national brand such as Keya, dedicated and steadfastly cultivated modified compounding equipment industry, can this vision become a reality in the near future.
