AI-Powered supplier vetting

SummaryZhejiang Zhongyang Screw Manufacturing Co., Ltd. is presented as a China-based manufacturer and distributor of screws, barrels, and related assembly parts for plastic and rubber machinery. The supplier reports 12 years of industrial experience, a factory equipped with advanced CNC machines, more than 10 production lines, 50 quality-control staff, and exports to South America, Southeast Asia/Mideast, and Europe. It describes an ISO-certified quality system established in 2006 and offers design, technical support, customer service, and overseas engineering assistance. However, the records contain material inconsistencies regarding factory size, workforce, business type, and R&D staffing. No verifiable customer cases or detailed financial-strength evidence is provided.

Supplier typeThe supplier is legally identified as Zhejiang Zhongyang Screw Manufacturing Co., Ltd., a China-based limited company. Its stated business is designing, manufacturing, rebuilding, and distributing screws, barrels, and assembly parts, although one record labels the company nature as a trading company, creating a classification inconsistency.

CertificationsThe supplier explicitly states that it has been an ISO-certified enterprise since 2006 and that it operates a complete quality-control system covering production through final products. The specific ISO standard and certificate details are not provided.

After-Sales capabilityThe supplier describes a dedicated after-sales team, customer archiving and follow-up through product receipt and trial, efficient problem resolution, and the ability to send engineers to customer locations in China or abroad when necessary. These statements support an established service capability, though no service performance metrics are supplied.

R&D capabilityThe supplier reports professional design teams and experienced, creative engineers who address technical problems and design new screws and barrels for performance improvement. However, the records provide no quantified R&D resources, patents, new-product results, or development timeline.

Production capacityThe supplier reports a 10,000 m² factory with advanced CNC equipment, more than 10 production lines, 50 quality-control staff, and a one-month off-peak lead time. Other records state a 5,000 m² plant and alternatively more than 50,000 m² with over 200 workers, so capacity is indicated but the scale data is inconsistent.

Customization capabilityThe supplier states that it maintains sales, design, production, inspection, and service teams, supports specific customer needs, and designs new screw and barrel configurations to achieve targeted performance. This directly supports customization capability, although no examples, engineering specifications, or limits are given.

Product Q&A

Q:What customization options are available for the screw barrel?

We can customize the screw structure and compression ratio according to different products and ingredients. Standard specifications are available, but we also support OEM/ODM services for specific requirements.

Q:What materials are used for the screw and barrel?
