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 minimum order quantity (MOQ)?

The MOQ is 1 set. We accept small orders to accommodate diverse client needs.

Q:What is the lead time for delivery?

Lead time varies by size and type. Nitriding single screws take 40-70+ days, parallel twin screws 45-60+ days, and conical twin screws 35-60+ days. Bimetallic screws require an additional 5 days.

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

Lifespan depends on the formula and heat treatment. For 30phr nitriding, expect 3-5 years. Bimetallic screws and barrels have an extended lifespan due to their wear-resistant alloy layer.

Q:Can you customize the screw and barrel specifications?

Yes, we offer full OEM/ODM services. You can customize materials, hardness, nitriding depth, and dimensions. Screw structure and compression ratio can be designed according to different products.

Q:How can I improve the properties of my current screw and barrel?

Our engineers can revise or redesign your screw and barrel to improve output or melt quality. We offer customized solutions and reverse engineering services using 3D scanning.
