SummaryNantong Weihua Import & Export Co., Ltd is a China-based limited company in Jiangsu, identified as both a trading company and manufacturer/factory, with products focused on sheet-metal forming and related industrial machinery. Evidence indicates export activity since 2003, exports to multiple regions, stated annual productivity of 2,000 sheet-metal machine sets, and peak-season fulfillment of 2–3 months. The supplier reports ISO 9001 and ISO 14001 certifications, 24/7 technical and spare-parts support, and R&D engineering experience of 31–40 years in aggregate. It claims customization-oriented product recommendations and applications across several industrial sectors. However, the available trade record shows only one transaction and does not establish a broad customer-case history. Financial credibility cannot be assessed because financial information is excluded.

Supplier typeThe supplier is identified as a trading company and manufacturer/factory, legally organized as a limited company in Jiangsu, China. Its stated business covers industrial equipment and manufacturing machinery, with product keywords centered on rolling, bending, and sheet-metal forming machines.

CertificationsThe supplier explicitly reports ISO 9001:2008 international quality-system certification and ISO 14001 and ISO 9001 management-system certifications. These statements provide direct evidence of certification holding, although the slices do not provide certificate numbers, validity dates, or issuing-body details.

After-Sales capabilityThe supplier states that it provides 24/7 free-call technical support and comprehensive, consistent technical and spare-parts service after sales. It also claims quality testing before delivery, directly indicating a defined after-sales support commitment.

R&D capabilityThe supplier states that Huaxi Machinery began production in 2002 and focuses on R&D and manufacturing of sheet-metal forming machinery, while the reported total experience of R&D engineers is 31–40 years. These statements support established R&D capability, though they do not document specific patents, new product launches, or measurable innovation outcomes.

Production capacityThe supplier describes machining equipment including large-scale lathes, boring, drilling, milling, and welding machines, and reports annual productivity of 2,000 sheet-metal machine sets. It also states a peak-season fulfillment time of 2–3 months and production of multiple machine categories, supporting a documented production base.

Customization capabilityThe supplier states that it introduces suitable products according to customer requests and provides solutions across multiple machine types, including three- and four-roll bending machines, angle rolls, laser cutting machines, and press brakes. Its description of CNC equipment handling complex, fine, small-batch, and varied parts further supports flexibility, although no specific customized project is documented.

Product Q&A

Q:What is the expected service life of the rolling machine?

The service life can reach up to 10 years if normal maintenance is performed according to instructions. However, it depends on worker skills, experience, and daily working hours; working 12 hours or more may affect longevity.

Q:What types of rolling machines do you offer?

We offer three main types: Mechanical 3-roller, Hydraulic 3-roller with pre-bending, and Hydraulic 4-roller with pre-bending.

Q:What are the specifications and styles available?

We provide light and heavy types with thickness ranging from 6-150mm and width from 1000-12000mm. Special machines can be manufactured for smaller diameters or specific applications like oil pipes and wind towers.

Q:Can the machine be customized for specific needs?

Yes, we can manufacture machines according to special customer requests, including custom colors (White + Red or others) and voltage frequencies (380V, 50HZ or customer request).

Q:What are the advantages of the four-roll design?

The four-roll design offers faster operation (50-80% faster than three-roll), better accuracy, reduced flat-end issues, and allows finishing cylinders in one pass without removing or turning plates.
