AI-Powered supplier vetting

SummaryZhengzhou Great Machinery Co., Ltd. is identified as a China-based manufacturer/factory in Henan, specializing in extrusion and plastic-processing equipment, including screen changers, melt gear pumps, chemical pumps, and recycling or pelletizing machinery. The supplier reports ISO 9001 certification, more than 10 production lines, 6–10 R&D engineers, 6–10 quality-control staff, and stated annual outputs of 1,100 melt gear pumps and 1,200 screen changers. Its description claims strict production and quality control and pre-sales/post-sales technical service, but the provided information does not independently substantiate service performance or customization capability. One associated buyer and an import record are available, indicating at least some transaction activity. Financial credibility cannot be assessed because financial figures are excluded from this analysis.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and Limited Company based in Zhengzhou, Henan, China. Its listed business areas and products cover packaging and printing, industrial equipment, textile, machinery, chemicals, screen changers, melt pumps, recycling machinery, and pelletizing lines.

CertificationsThe supplier reports holding ISO 9001 certification for its management systems. This is explicit evidence of certification, although no certificate number, issuing body, scope, or validity period is provided.

After-Sales capabilityThe company states that its professional technical team provides pre-sales and post-sales services. This supports the existence of a claimed service capability, but no service personnel details, response standards, service locations, or verified service outcomes are provided.

R&D capabilityThe supplier describes an ever-improving design approach, a professional technical team, and a mission focused on developing environmentally friendly plastic-extrusion products. Its product range includes several screen-changer designs and specialized pumps, while 6–10 R&D engineers are reported; however, no patents, new-product records, or measurable innovation results are provided.

Production capacityThe supplier reports operating more than 10 production lines and producing 1,100 melt gear pumps and 1,200 screen changers annually. Its product portfolio and stated output provide explicit evidence of established manufacturing capability in extrusion and plastic-processing equipment.

Client casesThe records identify SYNTECH FIBRES PRIVATE LIMITED as an associated buyer and show a textile-machine-parts product transaction involving the supplier, with Pakistan listed among import destinations. This demonstrates at least one documented buyer relationship, but the evidence is too limited to assess the breadth or quality of customer cases.

Product Q&A

Q:How does the dual piston screen changer work?

One piston moves out while the other stays in operation. The dirty screen is replaced, and the piston returns to venting stages before resuming, allowing continuous filtration.

Q:What materials can this screen changer process?

It is applicable for PP, PE, PS, EPE, EPS, XPS, and most other polymers used in non-woven, granulation, pipe, plate, sheet, and cast film applications.

Q:What is the warranty period and coverage?

We provide a 12-month warranty with free spare parts replacement for proper operation. Users bear transportation and packing fees.

Q:Can the size be customized?

Yes, various sizes are available to be matched with different extruders according to customer requirements.

Q:What is the lead time for production?

Lead time is one month during off-peak season and 1-3 months during peak season.
