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:How long is the service life of your product?

It depends on worker skills, experience, and daily working hours. With normal maintenance under instructions, the life can reach up to 10 years. Working 12 hours or more daily will affect the service life.

Q:What are the specific categories of your products?

We have three main kinds of roll bending machines: Mechanical 3 roller, hydraulic 3 roller with pre-bending, and hydraulic 4 roller with pre-bending.

Q:What are the specifications and styles of existing products?

We offer light and heavy types with thickness from 6-150mm and width 1000-12000mm. We can also make special machines per customer request, such as for smaller rolling diameters or specific applications like oil pipes and wind towers.

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

It is the fastest machine for rolling cans, requires only one position for side bending, finishes cylinders in one pass, and reduces flat ends through better pre-bending and clamping rolls.

Q:Is this machine suitable for CNC operation?

Yes, the four-roll design is most suitable for CNC operation as the plate is under better control, clamped between top and bottom rolls until the part is finished.
