Zhoushan Nanhaiya brought high wear-resistant barrels and screws to the Shenzhen and Tashkent Rubber and Plastics Exhibitions.

On April 15th, CHINAPLAS 2025, the highly anticipated international rubber and plastics exhibition, opened with great fanfare at the Shenzhen International Convention and Exhibition Center (Bao'an). Zhoushan Nanhai Asia Plastic Machinery Co., Ltd. showcased its full range of highly wear-resistant core products and customized solutions at the show. Across an exhibition area of over 380,000 square meters, the company showcased the precision strength of "Made in China" to professional visitors from 150 countries and regions.

At the exhibition, the Zhoushan Nanhaiya booth was bustling with visitors. Star products featured at the exhibition, such as the dual-alloy screw and barrel and the nitrided screw and barrel, attracted widespread attention with performance parameters far exceeding industry standards. Nanhaiya's products are all constructed from 38CrMoAl alloy steel and are crafted through multiple processes, including quenching and tempering, characterization, and precision machining. In particular, the barrel discharge port, a vulnerable section, features an innovative, full-circle carbide spray coating, achieving an internal hardness of 62HRC, a significant improvement over the industry average of 58HRC.

Especially noteworthy is the alloy layer depth of up to 2.5-3mm. The addition of tungsten alloy further enhances wear resistance, extending service life by over 40% compared to conventional products. These products are perfectly suited for demanding production environments in new energy vehicle parts, medical consumables, and high-end packaging. The modular screw and barrels on display can be flexibly combined to meet customer needs, providing integrated production solutions with complete production lines. These products have become a key focus for purchasing representatives from specialized, specialized, and innovative companies.

During the on-site inspection of the industry's advanced equipment and high-quality solutions at the exhibition, Nanhaiya also took the initiative to learn and think positively. It not only accurately grasped the current technological trends, but also transformed what it saw and heard into its own professional reserves, achieving dual growth in cognition and ability.

From September 21 to 23, 2025, Zhoushan Nanhaiya Plastic Machinery Co., Ltd. showcased its scaled-down screw and barrel models at its booth. With its leading wear-resistant technology and customized solutions, the products became a highlight of the exhibition, attracting numerous buyers from Central Asian countries such as Uzbekistan and Kazakhstan.

As a highly influential professional exhibition in Central Asia, this event, hosted by authoritative institutions such as the Ministry of Foreign Economic Relations, Investment and Trade of Uzbekistan, brought together companies from over ten countries, including China, Germany, and Russia, with an exhibition area exceeding 12,000 square meters. During the exhibition, Uzbekistan's "New Uzbekistan" national strategy and the infrastructure boom driven by the "Silk Road Revitalization Plan" became hot topics. The local demand for high-quality engineering equipment continued to rise, providing broad opportunities for cooperation for international exhibitors. Nanhaiya's core exhibits at this exhibition include a full range of products, including screws and barrels for injection molding machines and extruders. Its dual-alloy screw and barrel, constructed from 38CrMoAl alloy steel, is particularly eye-catching. Nanhaiya's products have long been supplied to large and medium-sized domestic and international plastics machinery manufacturers. Their technical specifications surpass national standards, effectively replacing imported products.

Targeting the specifics of the Central Asian market, Nanhaiya also highlighted its customized service capabilities. From small screws (Ø15mm) to large barrels (Ø940mm), and from standard extrusion equipment to specialized screw systems for PE, wood-plastic composites, and PVC, the company offers a full range of services, from concept design to complete production line equipment, tailored to customer production needs. At the exhibition, Nanhaiya reached preliminary cooperation agreements with three local Uzbek plastics manufacturers. The two parties will conduct in-depth discussions on screw and barrel upgrades for their production equipment.

After the exhibition, we also visited some local manufacturers to help them solve problems and obtain measurement equipment.
