AI-Powered supplier vetting

SummaryZhejiang Guangming Plastic Machinery Co., Ltd. is identified as a combined company manufacturing and selling plastic-processing equipment, plastic products, and mechanical components. It offers screw and barrel products, OEM for known brands, ODM, and customization from samples or designs. The supplier reports documented service procedures, complaint handling, corrective and preventive actions, four R&D engineers, design documentation, and CAD capability. Production is reported at one line, with no ongoing batch quantity reconciliation. Overseas service infrastructure is limited: no overseas warehouse, showroom, agents or branches, and no stated overseas-service countries. Financial records are referenced for 2022–2024, but the provided information does not establish financial strength. A BV audit is recorded, while the audit type and evaluation result are given only as numeric codes without interpretable certification details.

Supplier typeThe supplier is named Zhejiang Guangming Plastic Machinery Co., Ltd. and classified as a combined company. Its stated business scope covers manufacturing and sales of plastic-processing equipment, plastic products, and mechanical parts, plus technical services.

After-Sales capabilityThe supplier reports written and followed procedures for service capability assessment, corrective and preventive actions, and customer complaints. However, it has no overseas warehouse, showroom, overseas agent or branch, and reports zero countries offering overseas services, limiting verified overseas after-sales coverage.

R&D capabilityThe supplier has four R&D engineers, CAD capability, and design input, output, review, verification, and validation documents available for audit. It provides ODM services, but reports no new products in the past year and no available SDK.

Production capacityThe supplier reports one production line, one quality-control test equipment unit, 21–30 quality-control staff, and an annual production output category. It also reports no ongoing quantity reconciliation for each batch or mass production, which is a documented production-control weakness.

Customization capabilityCustomization is explicitly offered from samples and designs, with R&D engineers assigned to customization from designs. The supplier also provides ODM services and maintains related design documentation, supporting a demonstrated customization capability.

Product Q&A

Q:What is the MOQ?

1 Set is available.

Q:What is the lead time?

Lead time varies by size and type. Nitriding single screw/barrel takes 40-70+ days depending on diameter. Parallel twin screw takes 45-60+ days. Conical twin screw takes 35-60+ days. Bimetallic versions require an additional 5 days.

Q:What is the lifespan of the screw and barrel?

Lifespan varies with formula and heat treatment. For 30phr nitriding, expect 3-5 years. Bimetallic screw and barrel have an extended lifespan.

Q:How can we ensure your quality?

We partner with many extruder and screw & barrel makers in Europe and Asia, all satisfied with our quality. Before shipping, we provide test reports for material, heat treatment, and tolerance.

Q:Can I improve the current screw and barrel properties?

For unsatisfactory output or melt quality, our engineers can revise or redesign your screw and barrel. Customized solutions are available.
