[Shanghai, April 22-23, 2026] — The 38th CHINAPLAS International Plastics & Rubber Exhibition is being held at the National Exhibition and Convention Center (Hongqiao) in Shanghai, with the theme "Transformation, Collaboration, and Sustainable Development." As the most influential annual event in the global plastics and rubber industry, this year's exhibition has attracted over 5,000 high-quality exhibitors from home and abroad, covering an exhibition area of over 390,000 square meters, becoming an important platform for global plastics and rubber companies to showcase their innovative achievements.

Zhoushan Microwave Screw Machinery Co., Ltd. showcased its core technology product, the WB Microwave microwave screw extruder, at the exhibition, attracting a large number of industry buyers and professional visitors on the second day (April 22nd) and the third day (April 23rd).


1. Innovative Microwave Internal Heating Technology
Unlike traditional extruders that use external heating, the special screw exhibited by the company employs microwave-assisted internal heating technology. As seen in the exhibit, the screw's tail is wrapped with a precision copper-colored coil, a core component of the microwave generator, which directly heats the material inside the screw. This effectively solves the problem of traditional heating lag, significantly improving heating efficiency and reducing energy consumption, making it particularly suitable for processing heat-sensitive materials.

2. Planetary Screw Extruder System
The company's planetary extruder components were a highlight of the exhibition. Their unique internal gear and external gear ring structure design enables high-intensity shearing and mixing of polymer materials, resulting in more uniform heating and significantly improved plasticizing.

3. EPE Foaming Dedicated Screw Barrel
For the production of pearl cotton (EPE foam), the company showcased a dedicated foaming screw barrel. This equipment features a special venting and mixing section design, allowing for smooth addition of foaming agent and precise control of the foaming ratio under low pressure, preventing material breakage and meeting the production requirements of high-quality insulation materials.

Zhoushan Microwave Screw Machinery Co., Ltd., located in Zhoushan, Zhejiang Province, enjoys a superior geographical location and convenient transportation. The company currently has over 80 employees, a workshop area of over 3,000 square meters, and possesses a complete management system, sophisticated manufacturing equipment, and a professional manufacturing team.
The company's main products include:
SJS series conical twin-screw extruders
WB-WE series planetary screw extruders
Various pipe, sheet, and profile production equipment
SJ series single-screw extruders
Microwave screw extruders. All products are manufactured using high-quality alloy steel, precision-machined and nitrided, featuring high precision, non-deformation, wear resistance, and corrosion resistance. The company strictly controls quality to ensure that every piece of equipment meets industry standards.
During the exhibition, the company specially arranged technical experts and sales consultants to provide one-on-one consultation services. For customers who inquired about prices, technical personnel explained in detail the technical parameters, application areas, and customization solutions of WB Microwave machinery.
The booth was professionally arranged, and the products were displayed in an orderly manner, including various specifications of screw components (twin-screw, planetary screw, special head screw, etc.), fully demonstrating the company's R&D strength and manufacturing level.




According to the company's technical staff, WB Microwave machinery and various extruders are mainly used in the following fields:
Foam Plastic Production: Thermal insulation materials such as EPE (expanded polyethylene) and XPS (extruded polystyrene board)
Modified Plastic Granulation: Mixed extrusion with fillers, masterbatches, and flame retardants
Fiber Spinning: Production of chemical fibers such as polyester and nylon
Food Extrusion Puffing: Rice crackers, pet food, etc.
Microwave Drying/Sterilization: Uniform heating treatment of granules or powders
Zhoushan Microwave Screw Machinery Co., Ltd. expresses its sincere gratitude to all customers who consulted and inquired during the exhibition. The company promises to continue providing customers with high-quality, efficient, and affordable products, adhering to the principle of "reputation first, service foremost," and working with you to create a business and share development.
